DESCRIPTION
These devices combine two popular functions, Watchdog
Timer, and Serial E
PROM Memory in one package. This
combination lowers system cost, reduces board space
requirements, and increases reliability.
2
The Watchdog Timer provides an independent protection
mechanism for microcontrollers. During a system failure,
the device will respond with a RESET/RESET signal
after a selectable time-out interval. The user selects the
interval from three preset values. Once selected, the
interval does not change, even after cycling the power.
The memory portion of the device is a CMOS Serial
E
PROM array with Xicor’s Block Lock
array is internally organized as x 8. The device features a
Serial Peripheral Interface (SPI) and software protocol
allowing operation on a simple four-wire bus.
2
TM
Protection. The
The device utilizes Xicor’s proprietary Direct Write
providing a minimum endurance of 100,000 cycles per
sector and a minimum data retention of 100 years.
