EEPROM Serial-SPI 16Kbit 2K x 8 3.3V/5V 8Pin SOIC N Tube
General Description
The FM25C160U is a 16K 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 microcontroller and the EEPROM. In addition, the serial interface allows a minimal pin count, packaging designed to simplify PC board layout requirements and offers the designer a variety of low voltage and low power options.
Features
■Sequential read of entire array
■16 byte "Page write" mode to minimize total write time per byte
■/WP pin and BLOCK WRITE protection to prevent inadvert ent programming as well as programming ENABLE and DISABLE opcodes.
