Intel is a storyline dating back decades, but there are signs that the two rivals are becoming closer frenemies and even collaborating. There's a good reason for that--Nvidia is a threat to both companies. Intel and AMD have teamed up on a custom GPU for next-gen mobile chips. Nvidia happens to be AMD's biggest GPU rival on PCs. AMD also wants its GPUs in the data center too. Nvidia is the GPU leader in the data center and threatens Intel on artificial intelligence and high-performance computing.

Intel wants to be the processor of data however it is used and sees Nvidia as fierce competition. Add it up and AMD and Intel may even need each other. The caveat: Intel and AMD won't be all warm and fuzzy over time. Intel poached Raja M. Koduri, chief architect of the Radeon Technologies Group and oversaw the development of the advanced Vega GPUs.

UNI/O Serial EEPROM The UNI/O Serial EEPROM is a single I/O EEPROM device that has been developed by Microchip Technology Inc. The EEPROM has been developed to work on the UNI/O Bus, a propriety single I/O bus protocol, also developed by Microchip Technology Inc. The Bus combines the clock and data lines into a single bit stream using the Manchester Encoding technique. To find out more on the working of the bus and the device click. The UNI/O Serial EEPROM family was designed keeping in mind the best features of the other Microchip EEPROM families namely the I2C, SPI and Microwire and has been optimized for embedded applications. This single I/O EEPROM family has the advantage of using just ONE MCU I/O pin as opposed to at least 4 MCU I/O’s needed by the SPI, 4 I/Os by the Microwire and at least 2 I/Os by the I2C. This helps: • Increase system value by freeing up extra I/O’s for other applications.

• Reduce system cost by shifting a smaller, lower pin count MCU. • Add memory to the MCU when the MCU is pin-limited. • Reduces board cost with fewer traces, ensuring more compact designs.

• Spike Filters for noise protection. • BOR circuitry – no false writes • State machine goes into “Idle” as a “Fail Safe” Mode • ESD Protection at all pins >4kV. Why Choose the UNI/O Serial EEPROM? Do you face the following issues? MCU needs external memory but you’re pin limited? Need to add new features to your existing design without having to shift to a more expensive MCU?

Want to lower system costs? (By using a smaller MCU) Need a more compact Design? Solution: The single I/O UNI/O EEPROM is the one stop solution to get around all of the above. How To Install Gta Sa Multiplayer Mod on this page. The UNI/O EEPROM not only gets around the pin limitation problem being a single I/O device, it has the dual advantage of either adding extra features to your existing MCU using these freed-up I/Os or shifting to a less expensive/smaller pin count MCU. The UNI/O Serial EEPROM was designed keeping in mind the best features of our other standard EEPROM buses, namely the I2C, Microwire and SPI. Here are some of the advanced features which can be used with UNI/O Serial EEPROMs: WIP Polling Software Write Protect. (Block Protect) Status Register Write Enable/Disable Current Address Read Software Addressable Set All/Erase All The UNI/O Serial EEPROM will also be the first and only EEPROM to fit into the small 3 lead SOT-23 package.

Finally, being a standard EEPROM device you continue to enjoy the standard benefits of EEPROMs like low supply voltage (1.8V) operation, wide temperature ranges (-40°C to 120°C) and high endurance (1M cycles). For more on the features and benefits of using the UNI/O EEPROM, click.

SPI Vs UNI/O EEPROM Using the UNI/O EEPROM instead of the SPI saves you at least 3 I/O pins on your MCU which can be used to add external features or enable you to shift to a smaller, less expensive MCU. Also, the UNI/O EEPROMs are priced cheaper than the SPI for the same density.

However, it must be noted that the SPI wins when the application demands higher speeds. Also the SPIs have a larger selection in terms of densities going all the way to 1 Mbit. The UNI/O EEPROM advantage: Fewer pins, design compactness, lower cost, smaller packages The SPI EEPROM advantage: Faster bus, wider densities (Up to 1 Mbit) I2C Vs UNI/O EEPROM The UNI/O EEPROM saves you at least one pin when compared to the I2C. Also, the I2C needs extra pull-up resistors as shown for the data and clock lines as a recommended practice to prevent these I/Os from floating. These can be done away with in the UNI/O bus thus ensuring not only lower system costs but a more compact design overall. The UNI/O serial EEPROM is also built in with additional features like the software write-protect feature and the status register which is not found in the standard I2C EEPROMs.

The I2C is however slightly faster than the UNI/O EEPROM and has a wider selection of densities. The UNI/O EEPROM advantage: Fewer I/O pins, design compactness, smaller packages, software write protect, status register The I2C EEPROM advantage: Slightly faster bus, wider densities (Up to 1Mbit), lower cost Summarizing, the UNI/O Space: Apart from the standard EEPROM space, the UNI/O Serial EEPROM wins particularly in these sockets: Pin Count is a Premium Only one I/O available, potential to use smaller/cheaper Microcontroller or add another features to applications when emulated EEPROM is not sufficient. Board Space is a Premium 3-pin SOT with simple hook up.

No external resistors required, fewer traces (more compact design).

The UNI/O Serial EEPROM: The UNI/O EEPROM (11xx Family) is a three pin Serial EEPROM Power (Vdd, Vss) SCIO – Serial Clock I/O Vss All Communication occurs on the SCIO (pin1) Working with the UNI/O Bus: Manchester Encoding: The UNI/O Bus is an asynchronous single I/O bus that uses the Manchester Encoding scheme to multiplex the data and clock on to a single I/O (SCIO).

With data stream Manchester-encoded the UNI/O device synchronizes to the MCU data rate. The clock signal is extracted by the receiver to correctly decode the data value of each bit. MCU establishes the data rate with the start header. UNI/O device will time out and go to standby if an expected transition is not seen. The EEPROM will sync to the MCU data rate as long as the clock frequency is between 10 KHz to 100 KHz. Both the master and slave can operate as transmitter or receiver but the master determines which mode is active. UNI/O Bus Bit Period The bit period is determined by the master and forms an integral part of the communication between the master and the receiver.

Difference Between Serial And Random Access Memory Full here. It is with this bit period that clock and data can be extracted. Bit period (TE) determined by the master. One data bit per bit period. Clock is extracted from the bit period – A transition always occurs at the middle of the bit period. Falling edge indicates a ‘0’ while a rising edge indicates a ‘1’. Bit period is between 10 us and 100 us. Clock rate is between 100 KHz and 10 KHz.

Falling Edge Indicates a “0”; Rising Edge Indicates a “1” UNI/O EEPROM Command Summary: 1. Standby Pulse Long pulse used to ensure device is in standby and ready to receive commands. Required after a POR/BOR. Required when an error occurs. Not required during consecutive commands to the same device. Start HeaderUsed by UNI/O device to synchronize with master. MCU must keep bit period the same until the next header is sent.

UNI/O device will transmit data at the same rate Standby pulse, start header example. Acknowledge MAK (Master Ack) – Occurs after each byte is sent by master MAK is sent as a “1” bit during the MAK period NoMAK is sent as a “0” bit during the MAK period NoMAK is used to terminate operation and initiate write cycle for write commands SAK (Slave Ack) – Slave tells master byte was received OK.

SAK is sent as a “1” bit during the SAK period NoSAK is sent as a lack of state change SAK always sent when no error detected Exception: not sent after start header NoSak sent for error conditions and after the start header Master will need to send a Standby Pulse if a NoSAK is received (except after start header) The MAK/SAK sequence ensures that both the master and the slave remain synchronized. The sequence also reduces the chance of false writes due to unexpected operation of the MCU. The MCU can tell every 8 bits if the slave is still synchronized. Acknowledge routine UNI/O Device Address The UNI/O EEPROM is designed to allow multiple devices on the same bus Each device has an address 11XXXX0 address is 0xA0 Device address precedes any command Future devices will have other addresses This will allow multiple devices on bus Reading from the UNI/O EEPROM Once the bit period, data rate, and device address has been established, the EEPROM can be read up to “n” consecutive bytes at a time.

The slave will send 8 bits of data at the current bus data rate The Master will need to determine the bit value during each bit period For sequential reads, the Master sends a MAK after the data byte The slave will send a SAK and another 8 bits. The address pointer will wrap around at the end of the array Sequential reads can be done forever Read Command Sequence Writing to the UNI/O EEPROM Write Enable (WREN) Sets Write Enable Latch (WEL) Required before every write to array & status register Byte Writes Once the write enable latch is set, the user may proceed with issuing a WRITE instruction (including the header and device address bytes) followed by the MSB and LSB of the Word Address. Once the last Acknowledge sequence has been performed, the master transmits the data byte to be written. (Also allow for 5 ms write cycle time after instruction.) Page Writes Write up to 16 bytes in one command Must stay within page boundary Must first set WEL with WREN command Implementing Page Write (Allow for 5ms Write cycle time after last SAK) UNI/O EEPROM Status Register The status register is an 8-bit register that provides write control and data protection. The Write-In-Process (WIP) bit indicates whether the 11XX is busy with a write operation. When set to a ‘1’, a write is in progress, when set to a ‘0’, no write is in progress.

This bit is read-only. The Write Enable Latch (WEL) bit indicates the status of the write enable latch. When set to a ‘1’, the latch allows writes to the array, when set to a ‘0’, the latch prohibits writes to the array. This bit is set and cleared using the WREN and WRDI instructions, respectively. This bit is read-only for any other instruction.

Reading the Status Register (RDSR) The RDSR instruction provides access to the STATUS register. The STATUS register may be read at any time, even during a write cycle. Reads the Status Register value Only command valid during write cycle Can repeatedly read value by sending MAK Useful for monitoring WIP Write Status Register (WRSR) The WRSR instruction allows the user to select one of four levels of protection for the array by writing to the appropriate bits in the STATUS register. The array is divided up into four segments. The user has the ability to write-protect none, one, two, or all four of the segments of the array. Writes BP1, BP0 bits in Status Register Must first set WEL with WREN command.
