FM25C160U
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. This SPI EEPROM family is designed to work with the 68HC11 or any other SPI-patible, high-speed microcontroller and offers both hardware (/WP pin) and software ("block write") data protection. For example, entering a 2-bit code into the STATUS REGISTER prevents programming in a selected block of memory and all programming can be inhibited by connecting the /WP pin to VSS; allowing the user to protect the entire array or a selected section. In addition, SPI...
