Functional Description
The Cypress CY14B101K combines a 1 Mbit nonvolatile static
RAM with a full featured real-time clock in a monolithic
integrated circuit. The embedded nonvolatile elements
incorporate QuantumTrap technology producing the world’s
most reliable nonvolatile memory. The SRAM can be read and
written an infinite number of times, while independent,
nonvolatile data resides in the nonvolatile elements.
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
alarm or periodic seconds, minutes, hours, or days. There is
also a programmable watchdog timer for process control.
