EEPROM devices handle 125C temperatures
The 25XX512 and 25XX1024 are the industry's only 512Kbit and 1Mbit SPI serial EEPROMs specified to operate up to 125C.
Microchip has released the 25AA1024 and 25LC1024 - the fastest 1Mbit serial EEPROM devices in the industry - along with the 25AA128, 25LC128, 25AA512 and 25LC512 128 and 512Kbit devices All of the new devices are specified to operate over an extended temperature range (up to 125C), and provide over one million erase/write cycles and 200-year data retention

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.
With byte-level reads and writes, the 10MHz 25XX128 and 25XX512 devices and the 20MHz 25XX1024 devices do not require sector erases prior to writes.
This provides faster programming times and lower program voltages.
The new devices also consume very low operating and standby currents, while supporting full voltage-range operation from 1.8 to 5.5V.
The 25XX512 and 25XX1024 are the industry's only 512Kbit and 1Mbit SPI serial EEPROMs specified to operate up to 125C.
These two devices also feature a "deep power-down mode", which further reduces standby currents when the EEPROM device is not in use.
For applications that require Flash-like operation, the 25XX1024 and 25XX512 devices offer sector erase, chip erase and read identification (ID) with four sectors per chip.
The devices' ability to respond to both serial EEPROM and Flash commands makes them the most flexible devices in their class.
Microchip's SEEVAL 32 Serial EEPROM Designer's Kit (Part number DV243002) enables quick and easy development of robust, reliable serial EEPROM-based applications, and includes support for the new 25XX128, 25XX512 and 25XX1024 devices.
The kit includes the SEEVAL 32 development board and interface software, Microchip's Total Endurance lifetime modelling and analysis software, a serial cable, power supply, sample pack and documentation.
The 25XX128 is available in an eight-pin PDIP, TSSOP, SOIC, SOIJ, 5 x 6mm DFN and rotated SOIC packages, the 25XX512 is available in an eight-pin PDIP, SOIC, SOIJ and 5 x 6mm DFN packages and the 25XX1024 is offered in an eight-pin PDIP, SOIJ and 5 x 6mm DFN packages.
