Overview  
The Cypress CY14X512PA combines a 512-Kbit nvSRAM[1] with  
a full-featured RTC in a monolithic integrated circuit with serial  
SPI interface. The memory is organized as 64 K words of 8 bits  
each. The embedded nonvolatile elements incorporate the  
QuantumTrap technology, creating the world’s most reliable  
nonvolatile memory. The SRAM provides infinite read and write  
cycles, while the QuantumTrap cells provide highly reliable  
nonvolatile storage of data. Data transfers from SRAM to the  
nonvolatile elements (STORE operation) takes place  
automatically at power-down. On power-up, data is restored to  
the SRAM from the nonvolatile memory (RECALL operation).  
You can also initiate the STORE and RECALL operations  
through SPI instruction.  
❐ 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 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 rate SPI write and read (with special fast read  
instructions)  
❐ Supports SPI mode 0 (0,0) and mode 3 (1,1)  
■ SPI access to special functions  
❐ Nonvolatile STORE/RECALL  
❐ 8-byte serial number  
❐ Manufacturer ID and Product ID  
❐ Sleep mode
