A ferroelectric random access 13 High-endurance 10 trillion (10 ) read/writes memory or F-RAM is nonvolatile and performs reads and writes similar to a RAM. It provides reliable data retention for 121 years 121-year data retention (See Data Retention and Endurance on page 12) while eliminating the complexities, overhead, and system level reliability problems caused by serial flash, EEPROM, and other NoDelay writes nonvolatile memories. Advanced high-reliability ferroelectric process Very fast serial peripheral interface (SPI) Unlike serial flash and EEPROM, the CY15B016Q performs write operations at bus speed. No write delays are incurred. Data Up to 16 MHz frequency is written to the memory array immediately after each byte is Direct hardware replacement for serial flash and EEPROM successfully transferred to the device. The next bus cycle can Supports SPI mode 0 (0, 0) and mode 3 (1, 1) commence without the need for data polling. In addition, the Sophisticated write protection scheme product offers substantial write endurance compared with other Hardware protection using the Write Protect (WP) pin nonvolatile memories. The CY15B016Q is capable of supporting 13 Software protection using Write Disable instruction 10 read/write cycles, or 10 million times more write cycles than Software block protection for 1/4, 1/2, or entire array EEPROM. These capabilities make the CY15B016Q ideal for nonvolatile Low power consumption memory applications requiring frequent or rapid writes. 300 A active current at 1 MHz Examples range from data collection, where the number of write 20 A (typ) standby current cycles may be critical, to demanding industrial controls where the Low-voltage operation: V = 3.0 V to 3.6 V DD long write time of serial flash or EEPROM can cause data loss. Automotive-E temperature: 40 C to +125 C The CY15B016Q provides substantial benefits to users of serial EEPROM or flash as a hardware drop-in replacement. The 8-pin small outline integrated circuit (SOIC) package CY15B016Q uses the high-speed SPI bus, which enhances the AEC Q100 Grade 1 compliant high-speed write capability of F-RAM technology. The device specifications are guaranteed over an automotive-e temperature Restriction of hazardous substances (RoHS) compliant range of 40 C to +125 C.
