The Simtek STK18TA8 combines a 1 Mbit nonvolatile  
static RAM and a full-featured real-time clock, in a  
reliable, monolithic integrated circuit.  
A
Serial  
Peripheral Interface (SPI) makes system integration  
simple. The embedded nonvolatile elements  
incorporate Simtek’s QuantumTrapTM technology  
producing the world’s most reliable nonvolatile  
memory. The SRAM provides unlimited read and write  
cycles, while independent, nonvolatile data resides in  
the highly reliable QuantumTrapTM cell. Data transfers  
from the SRAM to the nonvolatile elements (the  
STORE operation) takes place automatically at power  
down. On power up, data is restored to the SRAM (the  
RECALL operation) from the nonvolatile memory.  
Both the STORE and RECALL operations are also  
available under software control.  
The Real-Time Clock function provides an accurate  
clock with leap year tracking and a programmable,  
high accuracy oscillator. The Alarm function is  
programmable for one-time alarms or periodic  
seconds, minutes, hours, or days. There is also a  
programmable Watchdog Timer for process control.
