Secure SerialFlash
DESCRIPTION
128 x 8 bit
FEATURES
•64-bit Password Security
•One Array (112 Bytes) Two Passwords (16 Bytes)
The X76F102 is a Password Access Security Supervisor,
containing one 896-bit Secure Serial Flash array. Access to
the memory array can be controlled by two 64-bit
passwords. These passwords protect read and write
—Read Password
—Write Password
•Programmable Passwords
•Retry Counter Register
—Allows 8 tries before clearing of the array
•32-bit Response to Reset (RST Input)
•8 byte Sector Write mode
•1MHz Clock Rate
•2 wire Serial Interface
•Low Power CMOS
—2.0 to 5.5V operation
—Standby current Less than 1µA
—Active current less than 3 mA
•High Reliability Endurance:
—100,000 Write Cycles
•Data Retention: 100 years
•Available in:
—8 lead PDIP, SOIC, MSOP, TSSOP, and Smart
Card Module
operations of the memory array.
The X76F102 features a serial interface and
software protocol allowing operation on a popular two
wire bus
.
The bus signals are a clock Input (SCL) and a bidirectional
data input and output (SDA).
The X76F102 also features a synchronous response to reset
providing an automatic output of a hard-wired 32-bit
data stream conforming to the industry standard for
memory cards.
TM
The X76F102 utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 100,000 cycles and
a minimum data retention of 100 years.
