DESCRIPTION
The A25CM02 is electrically erasable programmable memory (EEPROM) organized as 262144 x 8 bits, accessed through the SPI bus.
The A25CM02 can operate with a supply range from 2.8V to 5.5V.
The A25CM02 offers an additional page, named the Identification Page (256 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.
The A25CM02 is available in SOP8, CSP8 Packages.
