M45PE10 is a 1-megabit page-erasable serial flash memory with byte-alterability and a 75 MHz SPI bus interface.
The M45PE10 is a 1‑Mbit (128 Kbit × 8 bit) serial paged flash memory accessed via a high‑speed SPI‑compatible bus. It supports page‑wise write, program and erase operations, and is organized into two sectors of 256 pages each.
Key features include a maximum 75 MHz SPI clock, a supply range of 2.7 V‑3.6 V, deep‑power‑down mode, over 100 000 write cycles, and more than 20 years of data retention. The device is offered in an ECOPACK® RoHS‑compliant package.
