ST M95320 M95320-W M95320-R M95320-S M95640 M95640-W M95640-R M95640-S Data Sheet
The document describes electrically erasable programmable memory devices accessed via a high-speed SPI-compatible bus. Available in 32Kbit (M95320 series) and 64Kbit (M95640 series) capacities, these chips support multiple supply voltages ranging from 1.65V to 5.5V depending on the specific model suffix.
Key features include compatibility with SPI Bus Serial Interface modes, adjustable read-only EEPROM areas, hardware protection for the status register, and enhanced ESD protection. The devices offer erase/write cycle endurance of over 100,000 or 1 million cycles and data retention exceeding 40 years.
