CY15B102Q 2-Mbit (256 K 8) Serial (SPI) Automotive F-RAM 2-Mbit (256 K 8) Serial (SPI) Automotive F-RAM Features Functional Overview 2-Mbit ferroelectric random access memory (F-RAM) logically The CY15B102Q is a 2-Mbit nonvolatile memory employing an organized as 256 K 8 advanced ferroelectric process. F-RAM is nonvolatile and 13 High-endurance 10 trillion (10 ) read/writes performs reads and writes similar to a RAM. It provides reliable data retention for 121 years while eliminating the complexities, 121-year data retention (See the Data Retention and Endurance table) overhead, and system-level reliability problems caused by serial flash, EEPROM, and other nonvolatile memories. NoDelay writes Advanced high-reliability ferroelectric process Unlike serial flash and EEPROM, the CY15B102Q performs write operations at bus speed. No write delays are incurred. Data Very fast serial peripheral interface (SPI) is written to the memory array immediately after each byte is Up to 25 MHz frequency successfully transferred to the device. The next bus cycle can Direct hardware replacement for serial flash and EEPROM commence without the need for data polling. In addition, the Supports SPI mode 0 (0, 0) and mode 3 (1, 1) product offers substantial write endurance compared with other Sophisticated write protection scheme nonvolatile memories. The CY15B102Q is capable of supporting 13 Hardware protection using the Write Protect (WP) pin 10 read/write cycles, or 10 million times more write cycles than EEPROM. 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. Device ID Examples range from data collection, where the number of write Manufacturer ID and Product ID cycles may be critical, to demanding industrial controls where the Low power consumption long write time of serial flash or EEPROM can cause data loss. 5 mA active current at 25 MHz The CY15B102Q provides substantial benefits to users of serial 750 A standby current EEPROM or flash as a hardware drop-in replacement. The 20 A sleep mode current CY15B102Q uses the high-speed SPI bus, which enhances the high-speed write capability of F-RAM technology. The device Low-voltage operation: V = 2.0 V to 3.6 V DD incorporates a read-only Device ID that allows the host to Automotive-E temperature: 40 C to +125 C determine the manufacturer, product density, and product revision. The device specifications are guaranteed over an 8-pin small outline integrated circuit (SOIC) package Automotive-E temperature range of 40 C to +125 C.
