Advanced 2-Wire Serial E PROM with Block Lock^TMProtection

FEATURES

DESCRIPTION

The X24645 is a CMOS 65,536-bit serial E²PROM,

internally organized 8192 x 8. The X24645 features a

•2.7V to 5.5V Power Supply

•Low Power CMOS

—Active Read Current Less Than 1mA

—Active Write Current Less Than 3mA

serial interface and software protocol allowing operation

on a simple two wire bus.

—Standby Current Less Than 1∝A

•Internally Organized 8192 x 8

•New Programmable Block Lock Protection

—Software Write Protection

—Programmable hardware Write Protect

Two device select inputs (S₁, S₂) allow up to four

devices to share a common two wire bus.

A Write Protect Register at the highest address location,

1FFFh, provides three new write protection

•Block Lock (0, 1/4, 1/2, or all of the E PROM

array)

features: Software Write Protect, Block Write Protect, and

Hardware Write Protect. The Software Write

•2 Wire Serial Interface

Protect feature prevents any nonvolatile writes to the

X24645 until the WEL bit in the write protect register is

•Bidirectional Data Transfer Protocol

•32 Byte Page Write Mode

—Minimizes Total Write Time Per Byte

•Self Timed Write Cycle

—Typical Write Cycle Time of 5ms

•High Reliability

—Endurance: 100,000 Cycles

—Data Retention: 100 Years

•Available Packages

set. The Block Write Protection feature allows the user to

individually write protect four blocks of the array by

programming two bits in the write protect register. The

Programmable Hardware Write Protect feature allows

the user to install the X24645 with WP tied to V_CC,

program the entire memory array in place, and then

enable the hardware write protection by programming a

WPEN bit in the write protect register. After this,

selected blocks of the array, including the write protect

as WP remains HIGH.
