CY14V101PS

1-Mbit (128K × 8) Quad SPI nvSRAM with

Real Time Clock

■ Temperature range

❐ Industrial: –40 °C to 85 °C

Features

■ Density

❐ 1 Mbit (128K × 8)

■ Packages

❐ 16-pin SOIC

■ Bandwidth

❐ 108-MHz high-speed interface

❐ Read and write at 54 MBps

Functional Overview

The Cypress CY14V101PS combines a 1-Mbit nvSRAM with a

QPI interface. The QPI allows writing and reading the memory in

either a single (one I/O channel for one bit per clock cycle), dual

(two I/O channels for two bits per clock cycle), or quad (four I/O

channels for four bits per clock cycle) through the use of selected

opcodes.

■ Serial Peripheral Interface

❐ Clock polarity and phase modes 0 and 3

❐ Multi I/O option – Single SPI (SPI), Dual SPI (DPI), and Quad

SPI (QPI)

■ High reliability

❐ Infinite read, write, and RECALL cycles

❐ One million STORE cycles to nonvolatile elements (SONOS

FLASH Quantum trap)

The memory is organized as 128 Kbytes each consisting of

SRAM and nonvolatile SONOS FLASH Quantum Trap cells. The

SRAM provides infinite read and write cycles, while the

nonvolatile cells provide highly reliable storage of data. Data

transfers from SRAM to the nonvolatile cells (STORE operation)

take place automatically at power-down. On power-up, data is

restored to the SRAM from the nonvolatile cells (RECALL

operation). The user can initiate the STORE and RECALL

operations through SPI instructions.

❐ Data retention: 20 years at 85 °C

■ Read

❐ Commands: Standard, Fast, Dual I/O, and Quad I/O

❐ Modes: Burst Wrap, Continuous (XIP)

■ Write

❐ Commands: Standard, Fast, Dual I/O, and Quad I/O

❐ Modes: Burst Wrap

■ Data protection

❐ Hardware: Through Write Protect Pin (WP)

❐ Software: Through Write Disable instruction

❐ Block Protection: Status Register bits to control protection

■ Special instructions

❐ STORE/RECALL: Transfer data between SRAM and

Quantum Trap nvSRAM

❐ Serial Number: 8-byte customer selectable (OTP)

❐ Identification Number: 4-byte Manufacturer ID and Product

■ Store from SRAM to nonvolatile SONOS FLASHQuantum Trap

❐ AutoStore: Initiated automatically at power-down with a small

capacitor (V_CAP

)

❐ Software: Using SPI instruction (STORE)

❐ Hardware: HSB pin

■ Recall from nonvolatile SONOS FLASH Quantum Trap to

SRAM

❐ Auto RECALL: Initiated automatically at power-up

❐ Software: Using SPI instruction (RECALL)

■ Low-power modes

❐ Sleep: Average current = 380 µA at 85 °C

❐ Hibernate: Average current = 8 µA at 85 °C

■ Operating supply voltages

❐ Core V_CC: 2.7 V to 3.6 V

❐ I/O V_CCQ: 1.71 V to 2.0 V
