FM24C256
256 KBit 2-Wire Bus Interface
Serial EEPROM with Write Protect
General Description
The FM24C256/C256L/C256LZ devices are 256 Kbits CMOS
nonvolatile electrically erasable memory. These devices offer the
designer different low voltage and low power options. They
conform to all requirements in the Extended IIC 2-wire protocol.
Furthermore, they are designed to minimize device pin count and
simplify PC board layout requirements.
The entire memory array can be write disabled (Write Protection)
by connecting the WP pin to V
CC
.
Functional address lines allow up to eight devices on the same
bus, for up to a total of 2 Mbit address space.
The IIC 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.
