General Description
The SA25F010 is a 1Mb (256K X 4) CMOS non-volatile serial Flash Memory. This device fully conforms to the SPI 4-wire protocol, is enabled through the Chip Select (CSb) pin, and uses Clock (SCK), Data-in (SI) and Data-out (SO) pins to synchronously control data transfer between the SPI microcontroller and the Serial FLASH memory.
