48L256 Datasheet (Microchip) - 256-Kbit SPI Serial EERAM

48L256, 256-Kbit SPI Serial EERAM

The Microchip Technology Inc.

48L256 serial EERAM has an SRAM memory core with hidden EEPROM backup.

The device can be treated by the user as a full symmetrical read/write SRAM.

Backup to EEPROM is handled by the device on any power disrupt, so the user can effectively view this device as an SRAM th
