This document provides preliminary information on a new product, which is a 32 Kbit, 256-byte page, fast program EEPROM memory accessed by SPI bus interface. It features a SPI bus compatible serial interface, large page size, fast programming, and low energy consumption.
The M35B32 is a 32 Kbit electrically erasable programmable memory (EEPROM) accessed through the SPI bus. It is designed to save and store up to 256 bytes within a very short time using an Event sector, which is convenient for unexpected power loss or urgent data storage. The device operates with a low energy budget and supports a supply voltage range of 2.5 V to 5.5 V.
