NM24C32
32K-Bit Extended 2-Wire Bus Interface
Serial EEPROM with Write Protect
General Description:
The NM24C32 devices are 32,768 bits of CMOS nonvolatile
electrically erasable memory. These devices offer the designer
different low voltage and low power options, and they conform to
all specifications in the Extended IIC 2-wire protocol. Furthermore,
they are designed to minimize device pin count and simplify PC
board layout requirements.
The upper half of the memory can be disabled (Write Protection)
by connecting the WP pin to V
CC. This section of memory then
becomes ROM.
This communication protocol uses CLOCK (SCL) and DATA I/O
(SDA) lines to synchronously clock data between the master (for
example a microprocessor) and the slave EEPROM device(s).
Fairchild EEPROMs are designed and tested for applications
requiring high endurance, high reliability, and low power con-
sumption.
