CY14E512PA
Features
512-Kbit nonvolatile static random access memory (nv SRAM)
- Internally organized as 64 K × 8
- STORE to Quantum Trap nonvolatile elements initiated automatically on power-down (Auto Store) or by using SPI instruction (Software STORE) or HSB pin (Hardware STORE)
- RECALL to SRAM initiated on power-up (Power-Up RECALL) or by SPI instruction (Software RECALL)
- Automatic STORE on power-down with a small capacitor
- High reliability
- Infinite read, write, and RECALL cycles
- 1 million STORE cycles to Quantum Trap
- Data retention: 20 years at 85 C
- Real time clock (RTC)
- Full-featured 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 k Hz)
- Capacitor or battery backup for RTC
- Backup current of 0.45 µA (typical)
- 40 MHz, and 104 MHz High-speed serial peripheral interface (SPI)
- 40 MHz clock rate SPI write and read with zero cycle delay
- 104 MHz clock...
