FM24C32U – 32K-Bit Standard 2-Wire Bus
Interface Serial EEPROM
General Description
FM24C32U is a 32Kbit CMOS non-volatile serial EEPROM orga-
nized 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 V
. This section of memory then becomes
unalterable until the WP pin is switched to V
SS
.
“LZ” and “L” versions of FM24C32U offer very low standby current
making them suitable for low power applications. This device is
offered in both SO and DIP packages.
Fairchild EEPROMs are designed and tested for applications
requiring high endurance, high reliability and low power consump-
tion.
