Overview

The CY15B104QN-50SXI is a 4Mbit non-volatile ferroelectric RAM (F-RAM) organized as 512K x 8. It features an SPI interface capable of 50 MHz operation and functions as a high-performance alternative to traditional EEPROM or Flash memory, offering instant non-volatile writes at bus speed. This device operates over a wide voltage range of 1.8V to 3.6V and is designed for applications requiring frequent or rapid data logging.

Why Choose This Part

F-RAM technology provides virtually unlimited write endurance and eliminates the write delays associated with EEPROM or Flash. The device consumes only 3mA at 50MHz and features ultra-low power modes, including a 0.7 microamp shutdown current, making it suitable for battery-operated systems.

Applications

Industrial Data Logging
Ideal for recording high-frequency sensor data where traditional non-volatile memory would exceed its write endurance limits.
Power-Loss Event Recording
Captures critical system state data immediately upon power failure without the need for large backup capacitors or long write cycles.
Configuration Storage
Maintains system parameters and calibration data with 151-year data retention and hardware write protection.

Getting Started

Communicate with the device using standard SPI Mode 0 or Mode 3 protocols. Use the dedicated 256-byte special sector for storing unique device identifiers or serial numbers. For prototyping, ensure the 8-SOIC package is correctly decoupled with a 0.1 microfarad capacitor near the VDD pin.
