FM24C32U – 32K-Bit Standard 2-Wire Bus  
Interface Serial EEPROM  
General Description  
Features  
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.  
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  
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. This section of memory then becomes  
I 32 byte page write mode  
I Self timed write cycle (6ms typical)  
I Hardware Write Protection for upper half of the array  
unalterable until the WP pin is switched to VSS  
.
I Low VCC programming lockout for VCC = 5V 10% (“H” option)  
Internal ERASE/WRITE logic is disabled if VCC is below 3.8V  
“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.  
I Endurance: 1 Million data changes  
I Data Retention: Greater than 40 years  
I Packages: 8-Pin DIP and 8-Pin SO  
Fairchild EEPROMs are designed and tested for applications  
requiringhighendurance, highreliabilityandlowpowerconsump-  
tion.  
I Temperature range  
Commercial: 0°C to +70°C  
Industrial (V): -40°C to +85°C  
Automotive (E): -40°C to +125°C
