FEATURES
DESCRIPTION
•64-bit Password Security
•One Array (240 Bytes) Two Passwords (16 Bytes)
The X76F200 is a Password Access Security Supervisor,
containing one 1920-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 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
—Allows 8 tries before clearing of the array
•32-bit Response to Reset (RST Input)
•8 byte Sector Write mode
bidirectional data input and output (SDA).
•1MHz Clock Rate
•2 wire Serial Interface
•Low Power CMOS
The X76F200 also features a synchronous response to reset
providing an automatic output of a hard-wired 32-bit
—2.0 to 5.5V operation
