The nvSRAM is a fast SRAM with a nonvolatile element Internally organized as 2048 K 8 (CY14B116K), in each memory cell. The memory is organized as 2048 K bytes 1024 K 16 (CY14B116M) of 8 bits each or 1024 K words of 16 bits each. The embedded Hands-off automatic STORE on power-down with only a nonvolatile elements incorporate the QuantumTrap technology, small capacitor producing the worlds most reliable nonvolatile memory. The STORE to QuantumTrap nonvolatile elements is initiated by SRAM can be read and written an infinite number of times. The software, device pin, or AutoStore on power-down nonvolatile data residing in the nonvolatile elements do not RECALL to SRAM initiated by software or power-up change when data is written to the SRAM. Data transfers from High reliability the SRAM to the nonvolatile elements (the STORE operation) takes place automatically at power-down. On power-up, data is Infinite read, write, and RECALL cycles restored to the SRAM (the RECALL operation) from the nonvol- 1 million STORE cycles to QuantumTrap atile memory. Both the STORE and RECALL operations are also Data retention: 20 years available under software control. Sleep mode operation The RTC function provides an accurate clock with leap year Full-featured real time clock (RTC) tracking and a programmable, high-accuracy oscillator. The Watchdog timer alarm function is programmable for periodic minutes, hours, Clock alarm with programmable interrupts days, or months alarms. There is also a programmable watchdog Backup power fail indication timer. Square wave output with programmable frequency For a complete list of related documentation, click here.
