The M45PE10 is a 1Mbit, low voltage, page erasable serial flash memory with byte alterability and a 33 MHz SPI bus interface.
The M45PE10 provides 1 Mbit (128 K × 8 bit) of serial flash memory organized in 512 pages of 256 bytes each. It supports page‑write and page‑program operations of up to 256 bytes, sector erase of 512 Kbit, and deep power‑down mode for ultra‑low standby current.
The device operates from a single 2.7 V to 3.6 V supply and uses a standard SPI‑compatible bus with a maximum clock rate of 33 MHz. Features include more than 100 000 write cycles, over 20 years data retention, and hardware protection modes such as write‑protect and deep power‑down.
