The CY15B204QN-40SXET is a 4-Mb EXCELON™ Auto Ferroelectric RAM (F-RAM) organized as 512K × 8 with high-speed SPI up to 40 MHz. It delivers virtually unlimited endurance of 1013 read/write cycles and 121-year data retention, making it ideal for frequent, rapid-write automotive and industrial systems. Operating from 1.8 V to 3.6 V across -40°C to +125°C, it meets AEC-Q100 Grade 1 and RoHS standards. Provided in an 8-pin SOIC package, it is Pb-free and tape-and-reel capable.

Features

  • 4-Mb F-RAM, 512K × 8 organization
  • 1013 read/write cycle endurance
  • 121-year data retention at 85°C
  • Instant non-volatile write technology
  • Up to 40 MHz SPI interface
  • Supports SPI Modes 0 and 3
  • Hardware and software write protection
  • Dedicated 256-byte special sector
  • Unique device ID and serial number
  • Low power: 3.9 mA active, 0.1 µA hibernate
  • Deep power-down and hibernate modes
  • Input/output capacitance: 6/8 pF

Benefits

  • Reliable storage for frequent data logging
  • Eliminates data loss from power failures
  • Enables instant write, no wait time
  • High-speed SPI simplifies integration
  • Flexible use with multiple SPI modes
  • Protects data from accidental writes
  • Special sector survives soldering cycles
  • Easy device tracking and authentication
  • Minimizes energy use in standby
  • Extends battery life in low-power modes
  • Reduces EMI with low pin capacitance
  • Drop-in replacement for serial EEPROM/flash
