FM25C041U - Fairchild Semiconductor

FM25C041U 4K-Bit SPI Interface Serial CMOS EEPROM

The FM25C041U is a 4K (4,096) bit serial interface CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory). This device fully conforms to the SPI 4-wire protocol which uses Chip Select (/CS), Clock (SCK), Data-in (SI) and Dataout (SO) pins to synchronously control data transfer between the SPI microcontroller and the EEPROM. In addition, the serial.

Features

I Sequential read of entire array I 4 byte "Page write" mode to minimize total write time per byte I /WP pin and BLOCK WRITE protection to prevent inadvertent programming as well as programming ENABLE and DISABLE opcodes. I /HOLD pin to suspend data transfer I Typical 1µA standby current (ISB) for "L" devices and 0.1µA standby current for "LZ" devices.
