CY14B108M-ZSP25XI

CY14B108M-ZSP25XI is a 8Mbit (1024 K × 8/512 K × 16) nvSRAM with real time clock. This combines a 8Mbit non-volatile static RAM (nvSRAM) with a full featured RTC in a monolithic integrated circuit. The embedded non-volatile elements incorporate QuantumTrap technology producing the world’s most reliable non-volatile memory. The SRAM is read and written infinite number of times, while independent non-volatile data resides in the non-volatile elements. 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 for process control.

• 25ns access times, 1 million STORE cycles to QuantumTrap
• Hands off automatic STORE on power-down with only a small capacitor
• STORE to QuantumTrap non-volatile elements is initiated by software
• RECALL to SRAM initiated by software or power-up, high reliability
• 20 year data retention, single 3V +20%, –10% operation, watchdog timer
• Clock alarm with programmable interrupts
• 54-pin TSOPII package
• Industrial temperature range from (–40 to 85°C)
• Capacitor or battery backup for RTC
• Infinite read, write and RECALL cycles
