A ferro- 15 electric random access memory or F-RAM is nonvolatile and Virtually unlimited endurance of 1000 trillion (10 ) read/write performs reads and writes similar to a RAM. It provides reliable cycles data retention for 151 years while eliminating the complexities, 151-year data retention (See Data Retention and Endurance overhead, and system-level reliability problems caused by serial on page 20) flash, EEPROM, and other nonvolatile memories. NoDelay writes Advanced high-reliability ferroelectric process Unlike serial flash and EEPROM, the CY15X104QN performs write operations at bus speed. No write delays are incurred. Data Fast serial peripheral interface (SPI) is written to the memory array immediately after each byte is Up to 50 MHz frequency 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 product offers substantial write endurance compared to other Sophisticated write protection scheme nonvolatile memories. The CY15X104QN is capable of Hardware protection using the Write Protect (WP) pin 15 supporting 10 read/write cycles, or 1000 million times more Software protection using Write Disable (WRDI) instruction write cycles than EEPROM. Software block protection for 1/4, 1/2, or entire array These capabilities make the CY15X104QN ideal for nonvolatile Device ID and Serial Number memory applications, requiring frequent or rapid writes. Examples range from data collection, where the number of write Device ID contains manufacturer ID and product ID cycles may be critical, to demanding industrial controls where the Unique ID long write time of serial flash or EEPROM can cause data loss. Serial Number The CY15X104QN provides substantial benefits to users of Dedicated 256-byte special sector F-RAM serial EEPROM or flash as a hardware drop-in replacement. The Dedicated special sector write and read CY15X104QN uses the high-speed SPI bus, which enhances Stored content can survive up to three standard reflow sol- the high-speed write capability of F-RAM technology. The device dering cycles incorporates a read-only Device ID and Unique ID features, which allow the host to determine the manufacturer, product Low-power consumption density, product revision, and unique ID for each part. The device 2.4 mA (typ) active current at 40 MHz also provides a writable, 8-byte serial number registers, which 2.3 A (typ) standby current can be used to identify a specific board or a system. 0.70 A (typ) Deep Power Down mode current For a complete list of related resources, click here. 0.1 A (typ) Hibernate mode current Low-voltage operation CY15V104QN: V = 1.71 V to 1.89 V DD CY15B104QN: V = 1.8 V to 3.6 V DD Commercial and industrial operating temperature Commercial operating temperature: 0 C to +70 C Industrial operating temperature: 40 C to +85 C Packages 8-pin Small Outline Integrated Circuit (SOIC) package 8-pin Grid-Array Quad Flat No-Lead (GQFN) package Restriction of hazardous substances (RoHS) compliant Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 408-943-2600 Document Number: 002-19436 Rev. *K Revised July 15, 2019
