DESCRIPTION
The X76F041 is a password access security supervisor
device, containing four 128 x 8 bit SecureFlash arrays.
Access can be controlled by three 64-bit programmable
passwords, one for read operations, one for write opera-
tions and one for device configuration.
The X76F041 features a serial interface and software
protocol allowing operation on a simple two wire bus. The
bus signals are a clock input (SCL) and a bidirectional
data input and output (SDA). Access to the device is con-
trolled through a chip select input (CS), allowing any
number of devices to share the same bus.
The X76F041 also features a synchronous response to
reset; providing an automatic output of a pre-configured
32-bit data stream conforming to the ISO standard for
memory cards.
The X76F041 utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 100,000 cycles
per sector and a minimum data retention of 100 years.
