FM24C64EM8

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. Rochester Electronics Manufactured Components Rochester branded components are manufactured using either die/wafers purchased from the original suppliers or Rochester wafers recreated from the original IP. All re-creations are done with the approval of the Original Component Manufacturer (OCM). Parts are tested using original factory test programs or Rochester developed test solutions to guarantee product meets or exceeds the OCM data sheet.

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 Block Diagram VSS WRITE LOCKOUT VCC H.V.
