Datasheet
FM24C64
64K-Bit Standard 2-Wire Bus Interface Serial EEPROM
FM24C64 is a 64Kbit CMOS non-volatile serial EEPROM organized 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 – 64K-Bit Standard 2-Wire Bus
Interface Serial EEPROM
General Description
Features
FM24C64 is a 64Kbit CMOS non-volatile serial EEPROM organized 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.
■ Extended operating voltage: 2.5V to 5.5V
■ Up to 400 KHz clock frequency at 2.5V to 5.5V
■ Low power consumption
— 0.5mA active current typical
— 10µA standby current typical
— 1µA standby current typical (L version)
— 0.1µA standby current typical (LZ version)
■ Schmitt trigger inputs
FM24C64 offers hardware write protection where by the entire
memory array can be write protected by connecting WP pin to VCC.
This section of memory then becomes unalterable until the WP pin
is switched to VSS.
■ 32 byte page write mode
■ Self timed write cycle (6ms typical)
■ Hardware Write Protection for the entire array
“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.
■ Endurance: up to 100K data changes
Fairchild EEPROMs are designed and tested for applications
requiring high endurance, high reliability and low power consumption.
■ Temperature range
— Commercial: 0°C to +70°C
— Industrial (E): -40°C to +85°C
— Automotive (V): -40°C to +125°C
■ Data Retention: Greater than 40 years
■ Packages: 8-Pin DIP, 8-Pin SO and 8-Pin TSSOP
