Description
CY14B116K/CY14B116M
16-Mbit (2048 K × 8/1024 K × 16) nvSRAM with Real Time Clock
Features
■ 16-Mbit nonvolatile static random access memory (nvSRAM) ❐ 25-ns and 45-ns access times ❐ Internally organized as 2048 K × 8 (CY14B116K), 1024 K × 16 (CY14B116M) ❐ Hands-off automatic STORE on power-down with only a small capacitor ❐ STORE to QuantumTrap nonvolatile elements is initiated by software, device pin, or AutoStore on power-down ❐ RECALL to SRAM initiated by software or power-up
■ High reliability
❐ Infinite read, write, and RECALL cycles ❐ 1 million STORE cycles to QuantumTrap ❐ Data retention: 20 years
■ Sleep mode operation
■ Full-featured real time clock (RTC) ❐ Watchdog timer ❐ Clock alarm with programmable interrupts ❐ Backup power fail indication ❐ Square wave output with programmable frequency (1 Hz, 512 Hz, 4096 Hz, 32.768 kHz) ❐ Capacitor or battery backup for RTC ❐ Backup current of 0.45 A (typical)
■ Low power consumption ❐ Ac...
