M95320-125 is a 32-Kbit serial SPI bus EEPROM with high-speed clock released by ST company. Its features include: compatible with Serial Peripheral Interface (SPI) bus, 32 Kb (4 Kbytes) of EEPROM, page size of 32 bytes, fast write speed, page write within 5 ms, write protection, single supply voltage, wide operating temperature range, ESD protection and long data retention.

The M24C32-125 is ST's automotive 32-Kbit serial I²C bus EEPROM, supporting 400 kHz fast mode and 100 kHz standard mode. It has a 32Kbit (4Kbyte) EEPROM memory array, a page size of 32 bytes, a write time of 5ms, a single supply voltage of 2.5V to 5.5V, a working temperature range of -40°C to +125°C, support for random and sequential read modes, write protection of the entire memory array, enhanced ESD/Latch-Up protection, more than 1 million write cycles, and data retention of more than 40 years.

This document describes the M95640 and M95320 serial SPI bus EEPROMs with high-speed clock and various features. They are compatible with the SPI bus serial interface, support a single supply voltage, and have adjustable size read-only EEPROM area, byte and page write functions, and self-timed programming cycle. Additionally, they feature enhanced ESD protection, more than 100,000 or 1,000,000 erase/write cycles (depending on ordering options), and more than 40-year data retention.
