The CY15B204QI-20LPXI is a 4-Mbit (512K × 8) Excelon LP ferroelectric RAM (F-RAM) with high-speed SPI interface up to 20 MHz. It delivers virtually unlimited endurance with 10^15 read/write cycles and 151-year data retention at 60°C. Operating from 1.8 V to 3.6 V across -40°C to +85°C, it features advanced write protection and low active current (1.4 mA at 20 MHz). Drop-in compatibility with serial EEPROM and flash enables reliable storage in industrial and IoT systems.

Features

  • 4-Mbit nonvolatile F-RAM, 512K x 8
  • Virtually unlimited endurance: 10^15 cycles
  • 151-year data retention at 60°C
  • NoDelay™ writes, instant at bus speed
  • Up to 20 MHz SPI interface, modes 0 and 3
  • Advanced ferroelectric process technology
  • Hardware and software write protection
  • Dedicated 256-byte special sector
  • Unique Device ID and serial number
  • Low active current: 1.4 mA at 20 MHz
  • Deep power down: 1.0 µA, Hibernate: 0.1 µA
  • Input voltage range: 1.8 V to 3.6 V

Benefits

  • Reliable data even after 151 years
  • 10^15 cycles enable frequent data logging
  • Instant writes eliminate wait times
  • 20 MHz SPI supports fast data transfer
  • Robust protection prevents accidental writes
  • Special sector survives solder reflow
  • Unique ID simplifies device tracking
  • Low power extends battery life
  • Wide voltage fits many designs
  • Drop-in replacement for EEPROM/flash
  • No wear leveling or refresh needed
  • High-speed write for real-time systems
