Product Overview
CY15B104QN-50SXA is a CY15B104QN EXCELON™ automotive grade, 4Mb non-volatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is non-volatile and performs reads and writes similar to a RAM. It provides reliable data retention for 151 years while eliminating the complexities, overhead, and system-level reliability problems caused by serial flash, EEPROM, and other non-volatile memories. It provides substantial benefits to users of serial EEPROM or flash as a hardware drop-in replacement. This 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 and Unique ID features, which allow the host to determine the manufacturer, product density, product revision, and unique ID for each part. The device also provides a writable, 8-byte serial number registers, which can be used to identify a specific board or a system.
- Virtually unlimited endurance of 100 trillion (1014) read/write cycles
- Advanced high-reliability ferroelectric process, fast serial peripheral interface (SPI)
- Up to 50MHz frequency, supports SPI mode 0 (0, 0) and mode 3 (1, 1)
- Hardware protection using the write protect active-low (WP) pin, low-power consumption
- Software protection using write disable active-low (WRDI) instruction
- 2.7µA (typ) standby current, low-voltage operation: VDD = 1.8V to 3.6V, 50MHz frequency
- AEC-Q100 grade 3 compliant, automotive-A temperature range from (-40°C to +85°C)
- 8-pin SOIC (EIAJ) package, no inrush current control
- Software block protection for 1/4, 1/2, or entire array
- Stored content can survive up to 3 standard reflow soldering cycles
