The Cypress CY14B116K/CY14B116M combines a 16-Mbit nvSRAM with a full-featured RTC in a monolithic integrated circuit. The nvSRAM is a fast SRAM with a nonvolatile element in each memory cell. 该存储器采用“2048 K 字节,每字节 8 位”或“1024 K 字,每字 16 位”的组织方式。The embedded nonvolatile elements incorporate the QuantumTrap technology, producing the world’s most reliable nonvolatile memory. The SRAM can be read and written an infinite number of times. The nonvolatile data residing in the nonvolatile elements do not change when data is written to the SRAM. 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 RTC function provides an accurate clock with leap year tracking and a programmable, high-accuracy oscillator. The alarm function is programmable for periodic minutes, hours, days, or months alarms. There is also a programmable watchdog timer.

Dear valued customer,
