X76F200
Secure SerialFlash
FEATURES
DESCRIPTION
• 64-bit password security
• One array (240 bytes) two passwords (16 bytes)
—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
The X76F200 is a password access security supervi-
sor, containing one 1920-bit Secure SerialFlash array.
Access to the memory array can be controlled by two
64-bit passwords. These passwords protect read and
write operations of the memory array.
The X76F200 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 bidirec-
tional data input and output (SDA).
• 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:
The X76F200 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.
The X76F200 utilizes Xicor’s proprietary Direct Write™
cell, providing a minimum endurance of 100,000
cycles and a minimum data retention of 100 years.
