This document describes the features and characteristics of the M25P05-A 512-Kbit serial flash memory, including flash memory capacity, programming and erasing speed, supply voltage, and serial interface.
The M25P05-A is a 512‑Kbit (64 K×8) serial flash memory that operates over a 2.3 V to 3.6 V supply range and supports a 50 MHz SPI bus. It offers page programming up to 256 bytes, sector and bulk erase functions, and a deep‑power‑down mode for low‑power applications.
The device includes advanced write‑protect mechanisms, more than 100 k erase/program cycles per sector, and a data retention guarantee of over 20 years. It is available in several compact packages such as SO8, VFQFPN8, TSSOP8 and UFDFPN8.
