CY14B108M-ZSP25XI

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

• STORE to QuantumTrap nonvolatile 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
