FM24C32U - 32K-Bit Standard 2-Wire Bus Interface Serial EEPROM

Description

FM24C32U is a 32Kbit CMOS non-volatile serial EEPROM organized as 4K 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.

Features

  • I Extended operating voltage: 2.7V to 5.5V I Up to 400 KHz clock frequency at 2.7V to 5.5V I Low power consumption.
  • 0.2mA active current typical.
  • 10µA standby current typical.
  • 1µA standby current typical (L version).
  • 0.1µA standby current typical (LZ version) I Schmitt trigger inputs I 32 byte page write mode I Self timed write cycle (6ms typical) I Hardware Write Protection for upper half of the array I Low VCC programming lockout for VCC = 5V± 10% (“H” optio.

FM24C32U – 32K-Bit Standard 2-Wire Bus Interface Serial EEPROM September 2002 FM24C32U – 32K-Bit Standard 2-Wire Bus Interface Serial EEPROM General Description FM24C32U is a 32Kbit CMOS non-volatile serial EEPROM organized as 4K 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). FM24C32U is designed to minimize pin count and simplify PC board layout requirements. FM24C32U offers hardware write protection where by the upper half (upper 16Kbit) of the memory array can be write protected by connecting WP pin to VCC.
