FM25C640U - 64K-Bit SPI Interface Serial CMOS EEPROM
The FM25C640U is a 64K 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 Data-out (SO) pins to synchronously control data transfer between the SPI m
