The CY15B104QI-20BFXIT is a 4-Mbit EXCELON™ LP ferroelectric RAM (F-RAM) with a high-speed SPI interface up to 20 MHz, organized as 512K × 8. Operating from 1.8 V to 3.6 V across –40°C to +85°C, it is housed in an 8-pin UFLGA package. The device features virtually unlimited endurance of 10^15 read/write cycles, 151-year data retention at 60°C, advanced write protection, unique device ID, and ultra-low power operation for demanding industrial applications.

Features

  • 4-Mbit EXCELON™ LP F-RAM, 512K × 8
  • Virtually unlimited endurance: 10^15 cycles
  • 151-year data retention at 70°C
  • Instant non-volatile write, no delay
  • Fast SPI interface up to 20 MHz
  • Supports SPI mode 0 and 3
  • Hardware and software write protection
  • Unique device and serial number
  • 256-byte special sector for secure storage
  • Low active current: 1.2 mA at 20 MHz
  • Deep power-down and hibernate modes
  • Input/output capacitance: max 6/8 pF

Benefits

  • Reliable for frequent, rapid data logging
  • Prevents data loss during power failure
  • No write delays, maximizes system speed
  • Easy integration with standard SPI bus
  • Flexible protection for critical data
  • Enables device authentication and tracking
  • Secure storage for sensitive parameters
  • Minimizes power drain in standby modes
  • Reduces EMI with low pin capacitance
  • Suitable for long-life industrial systems
  • Drop-in replacement for serial EEPROM/flash
  • Simplifies board-level identification
