World's first serial EEPROM supporting ACR SIG
Microchip has announced the world's first serial EEPROM supporting the Advanced Communications Riser Special Interest Group (ACR SIG) specification.
Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
In addition to the SOT-23, the new devices are available in the popular 2 x 3mm DFN package and all standard packages.
They were developed using Microchip's PMOS electrically erasable cell (PEEC) technology and therefore provide data retention up to 200 years and the best endurance in the industry, with well over one million erase/write cycles in most applications.
Until now, Microchip's SPI serial EEPROM product line has supported the 4 to 256Kbit density range.
These new devices extend the range into 1 and 2Kbit applications and provide a high-speed version of the current 4Kbit part in the 25xx040A.
With speeds up to 10MHz, the new devices enable designers to take maximum advantage of the high-speed capabilities of the SPIbus.
The 25AA010A and 25LC010A EEPROMs provide 1Kbit of memory density, the 25AA020A and 25LC020A provide 2Kbit, and the 25AA040A and 25LC040A provide 4Kbit, all capable of speeds up to 10MHz.
In addition to the 6-pin SOT-23 and 8-pin DFN packages, all of the new memories are available in 8-pin SOIC, TSSOP, MSOP and PDIP packages.
Because they are all offered in such a broad range of package options, these new devices provide an easy upgrade path for applications requiring small amounts of memory, with high speeds.
Microchip's SEEVAL 32 serial EEPROM designer's kit supports development using the 25xx010A, 25xx020A and 25xx040A devices.
The kit is Windows-compliant and includes Microchip's Total Endurance modelling software, a SEEVAL 32 developer board and user interface software, power supply, RS232 serial cable, serial EEPROM sample pack and quick start users' guide.
It is available today at www.microchipdirect.com.
