Secure SerialFlash

FEATURES

DESCRIPTION

•64-bit password security

•One array (496 bytes) two passwords (16 bytes)

The X76F400 is a password access security supervisor,

containing one 3968-bit Secure Serial Flash array.

—Read password

—Write password

Access to the memory array can be controlled by two 64-bit

passwords. These passwords protect read and

write operations of the memory array.

•Programmable passwords

•Retry counter register

The X76F400 features a serial interface and software

protocol allowing operation on a popular 2-wire bus.

—Allows 8 tries before clearing of the array

•32-bit response to reset (RST input)

•8 byte sector write mode

The bus signals are a clock input (SCL) and a bi-directional

data input and output (SDA).

•1MHz clock rate •2-wire

serial interface •Low

power CMOS

The X76F400 also features a synchronous response to

reset, providing an automatic output of a hard-wired

—2.5 to 5.5V operation

—Standby current less than 1µA

—Active current less than 3 mA

32-bit data stream, thereby meeting the industry standard

for memory cards.

The X76F400 utilizes Xicor’s proprietary Direct Write^™

•High reliability endurance:

—100,000 write cycles

cell, providing a minimum endurance of 100,000

cycles and a minimum data retention of 100 years.

•Data retention: 100 years

•Available in:

—8-lead, SOIC,TSSOP
