M95P16-IXMNT/E Ultra low-power 16 Mbit Serial SPI Page EEPROM

The M95P16-I and M95P16-E (hereinafter referred to complessively as M95P16) are manufactured with ST's advanced proprietary NVM technology. They offer byte flexibility, page alterability, high page cycling performance, and ultra low power consumption, equivalent to that of EEPROM technology.

These devices are a 16-Mbit SPI page EEPROM, organized as 4096 programmable pages of 512 bytes each, accessed through an SPI bus, with high-performance dual- and quad-SPI outputs.

The devices offer two additional (identification) 512-byte pages:

Additional status, configuration and volatile registers set the desired device configuration, while the safety register provides information on the device status.

The M95P16-I operates with a supply voltage from 1.6 to 3.6 V, over an ambient temperature range of ‑40 °C to +85 °C. The M95P16-E offers an extended temperature range, from ‑40 °C to +105 °C. Both devices support a clock frequency of up to 80 MHz.

The M95P16 devices offer byte and page write instructions of up to 512 bytes. Write instructions consist in self-timed auto erase and program operations, resulting in flexible data byte management.

The devices also accept page/block/sector/chip erase commands, to set the memory to an erased state. The memory can then be fast-programmed by 512-byte pages, and further optimized using the Page program with buffer load instruction, to hide the SPI communication latency.
