CY14B101Q集成電路（IC）的存儲(chǔ)器規(guī)格書PDF中文資料

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

? Sleep mode current of 8 ?A
