FM24C128 – 128K-Bit Standard 2-Wire Bus Interface Serial EEPROM General Description Features FM24C128 is a 128Kbit CMOS non-volatile serial EEPROM organized as 16K 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). FM24C128 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 FM24C128 offers hardware write protection where by the entire memory array can be write protected by connecting WP pin to VCC. The entire memory then becomes unalterable until the WP pin is switched to VSS. ■ 64 byte page write mode ■ Self timed write cycle (6ms max) ■ Hardware Write Protection for the entire array “LZ” and “L” versions of FM24C128 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.
