NM24C65
64K-Bit Extended 2-Wire Bus Interface
Serial EEPROM with Write Protect
General Description:
The NM24C65 devices are 65,536 bits of CMOS nonvolatile
electrically erasable memory. These devices offer the designer
different low voltage and low power options, and they conform to
all 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.
