F-RAM

2-Mbit (256

K × 8) Serial (SPI) Automotive F-RAM

Features

Functional Overview

■ 2-Mbit ferroelectric random access memory (F-RAM) logically

organized as 256 K × 8

❐ High-endurance 10 trillion (10¹³) read/writes

❐ 121-year data retention (See the Data Retention and

Endurance table)

❐ NoDelay™ writes

The CY15B102Q is a 2-Mbit nonvolatile memory employing an

advanced ferroelectric process. F-RAM is nonvolatile and

performs reads and writes similar to a RAM. It provides reliable

data retention for 121 years while eliminating the complexities,

overhead, and system-level reliability problems caused by serial

flash, EEPROM, and other nonvolatile memories.

❐ Advanced high-reliability ferroelectric process

Unlike serial flash and EEPROM, the CY15B102Q performs

write operations at bus speed. No write delays are incurred. Data

is written to the memory array immediately after each byte is

successfully transferred to the device. The next bus cycle can

commence without the need for data polling. In addition, the

product offers substantial write endurance compared with other

nonvolatile memories. The CY15B102Q is capable of supporting

10¹³read/write cycles, or 10 million times more write cycles than

EEPROM.

■ Very fast serial peripheral interface (SPI)

❐ Up to 25 MHz frequency

❐ Direct hardware replacement for serial flash and EEPROM

❐ Supports SPI mode 0 (0, 0) and mode 3 (1, 1)

■ Sophisticated write protection scheme

❐ Hardware protection using the Write Protect (WP) pin

❐ Software protection using Write Disable instruction

❐ Software block protection for 1/4, 1/2, or entire array

These capabilities make the CY15B102Q ideal for nonvolatile

memory applications requiring frequent or rapid writes.

Examples range from data collection, where the number of write

cycles may be critical, to demanding industrial controls where the

long write time of serial flash or EEPROM can cause data loss.

■ Device ID

❐ Manufacturer ID and Product ID

■ Low power consumption

❐ 5 mA active current at 25 MHz

❐ 750 A standby current

The CY15B102Q provides substantial benefits to users of serial

EEPROM or flash as a hardware drop-in replacement. The

CY15B102Q uses the high-speed SPI bus, which enhances the

high-speed write capability of F-RAM technology. The device

incorporates a read-only Device ID that allows the host to

determine the manufacturer, product density, and product

revision. The device specifications are guaranteed over an

Automotive-E temperature range of –40 C to +125 C.

❐ 20 A sleep mode current

■ Low-voltage operation: V_DD= 2.0 V to 3.6 V

■ Automotive-E temperature: –40 C to +125 C

■ 8-pin small outline integrated circuit (SOIC) package

■ AEC Q100 Grade 1 compliant

■ Restriction of hazardous substances (RoHS) compliant
