A 15 ferroelectric random access memory or F-RAM is nonvolatile Virtually unlimited endurance of 1000 trillion (10 ) read/write and performs reads and writes similar to a RAM. It provides cycles reliable data retention for 151 years while eliminating the 151-year data retention (See Data Retention and Endurance complexities, overhead, and system-level reliability problems on page 17) caused by serial flash, EEPROM, and other nonvolatile NoDelay writes memories. Advanced high-reliability ferroelectric process Unlike serial flash and EEPROM, the CY15X102QN performs Fast SPI write operations at bus speed. No write delays are incurred. Data Up to 50 MHz frequency is written to the memory array immediately after each byte is Supports SPI mode 0 (0, 0) and mode 3 (1, 1) successfully transferred to the device. The next bus cycle can commence without the need for data polling. In addition, the Sophisticated write protection scheme product offers substantial write endurance compared to other Hardware protection using the Write Protect (WP) pin nonvolatile memories. The CY15X102QN is capable of Software protection using Write Disable (WRDI) instruction 15 supporting 10 read/write cycles, or 1000 million times more Software block protection for 1/4, 1/2, or entire array write cycles than EEPROM. Device ID and Serial Number These capabilities make the CY15X102QN ideal for nonvolatile memory applications, requiring frequent or rapid writes. Device ID contains manufacturer ID and product ID Examples range from data collection, where the number of write Unique ID cycles may be critical, to demanding industrial controls where the Serial Number long write time of serial flash or EEPROM can cause data loss. Dedicated 256-byte special sector F-RAM The CY15X102QN provides substantial benefits to users of Dedicated special sector write and read serial EEPROM or flash as a hardware drop-in replacement. The Stored content can survive up to three standard reflow sol- CY15X102QN uses the high-speed SPI bus, which enhances dering cycles the high-speed write capability of F-RAM technology. The device incorporates a read-only Device ID and Unique ID features, Low-power consumption which allow the host to determine the manufacturer, product 2.4 mA (typ) active current at 40 MHz density, product revision, and unique ID for each part. The device 2.3 A (typ) standby current also provides a writable, 8-byte serial number registers, which 0.70 A (typ) Deep Power Down mode current can be used to identify a specific board or a system. 0.1 A (typ) Hibernate mode current Low-voltage operation CY15V102QN: V = 1.71 V to 1.89 V DD CY15B102QN: V = 1.8 V to 3.6 V DD Industrial operating temperature: 40 C to +85 C Packages 8-pin Small Outline Integrated Circuit (SOIC) package 8-pin thin dual flat no leads (DFN) package 8-pin plastic dual in-line (PDIP) package Restriction of hazardous substances (RoHS) compliant Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 408-943-2600 Document Number: 002-26764 Rev. *B Revised March 19, 2020
