Functional Overview
●The Cypress CY14X101Q combines a 1-Mbit nvSRAM with a nonvolatile element in each memory cell with serial SPI interface. The memory is organized as 128 K words of 8 bits each. The embedded nonvolatile elements incorporate the QuantumTrap technology, creating the world’s most reliable nonvolatile memory.
●Features
●■ 1-Mbit nonvolatile static random access memory (nvSRAM) internally organized as 128 K × 8
● ❐ STORE to QuantumTrap nonvolatile elements initiated automatically on power-down (AutoStore) 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)
● ❐ Support automatic STORE on power-down with a small capacitor (except for CY14X101Q1A)
●■ High reliability
● ❐ Infinite read, write, and RECALL cycles
● ❐ 1million STORE cycles to QuantumTrap
● ❐ Data retention: 20 years at 85 °C
●■ 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 SPI 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
●■ Write protection
● ❐ Hardware protection using Write Protect (WP) pin
● ❐ Software protection using Write Disable instruction
● ❐ Software block protection for 1/4, 1/2, or entire array
●■ Low power consumption
● ❐ Average active current of 3 mA at 40 MHz operation
● ❐ Average standby mode current of 150 A
