X24320

400KHz 2-Wire Serial E PROM with Block Lock

4K x 8 Bit

FEATURES

•

Save Critical Data with Programmable

Block Lock Protection

—Block Lock (0, 1/4, 1/2, or all of E PROM Array)

—Software Write Protection

DESCRIPTION

The X24320 is a CMOS Serial E PROM, internally

organized 4K x 8. The device features a serial inter-

face and software protocol allowing operation on a

simple two wire bus. The bus operates at 400 KHz all

the way down to 1.8V.

Three device select inputs (S

–S

) allow up to eight

devices to share a common two wire bus.

A Write Protect Register at the highest address location,

FFFFh, provides three write protection features:

Software Write Protect, Block Lock Protect, and

Programmable Hardware Write Protect. The Software

Write Protect feature prevents any nonvolatile writes to the

device until the WEL bit in the Write Protect

the user four array block protect options, set by

programming two bits in the Write Protect Register. The

Programmable Hardware Write Protect feature

allows the user to install the device with WP tied to

, write to and Block Lock the desired portions of

the memory array in circuit, and then enable the In

Circuit Programmable ROM Mode by programming the

WPEN bit HIGH in the Write Protect Register. After this,

the Block Locked portions of the array, including

the Write Protect Register itself, are permanently

protected from being erased.
