FM24C64 – 64K-Bit Standard 2-Wire Bus
Interface Serial EEPROM
General Description
FM24C64 is a 64Kbit CMOS non-volatile serial EEPROM orga-
nized as 8K x 8 bit memory. This device confirms to Extended IIC
2-wire protocol that allows accessing of memory in excess of
16Kbit on an IIC bus. This serial communication protocol uses a
Clock signal (SCL) and a Data signal (SDA) to synchronously
clock data between a master (e.g. a microcontroller) and a slave
(EEPROM). FM24C64 is designed to minimize pin count and
simplify PC board layout requirements.
FM24C64 offers hardware write protection where by the entire
memory array can be write protected by connecting WP pin to V
CC
.
This section of memory then becomes unalterable until the WP pin
is switched to V
SS
.
“LZ” and “L” versions of FM24C64 offer very low standby current
making them suitable for low power applications. This device is
offered in SO, TSSOP and DIP packages.
Fairchild EEPROMs are designed and tested for applications
requiring high endurance, high reliability and low power consump-
tion.
