CY15B004J-SXA

Memory IC Overview

The CY15B004J-SXA is a 4-Kbit (512 × 8) serial ferroelectric random access memory (F-RAM) manufactured by Infineon Technologies. It utilizes an I2C interface with clock frequencies up to 1 MHz and operates within a voltage range of 2.7 V to 3.65 V. The device supports Automotive-A temperature conditions from –40 °C to +85 °C and features high endurance of 10^14 read/write cycles with data retention exceeding 151 years at 65 °C.

Memory IC Feature Summary

• Provides NoDelay writes that operate at bus speed without requiring write delays or polling
• Offers high endurance of 10^14 read/write cycles and extended data retention
• Functions as a direct hardware replacement for serial I2C EEPROMs

Memory IC Procurement Notes

Verify the specific ordering suffix 'SXA' corresponds to the standard 8-pin SOIC package configuration. Confirm that the Automotive-A qualification meets your system's environmental requirements. Ensure the I2C bus pull-up resistors are selected correctly for the target clock frequency. Check for RoHS compliance documentation if required by your manufacturing standards.

Memory IC Selection Notes

Select this component when replacing serial EEPROMs to eliminate write latency and improve system reliability. Consider the 4-Kbit capacity and I2C interface compatibility with your microcontroller. Evaluate the Automotive-A temperature range against your operational environment. Assess the low power requirements to ensure they align with your battery or power budget constraints.

Memory IC Part Context

This part belongs to the CY15B004J series of 4-Kbit F-RAM devices. It shares the same logical organization and interface protocol as other variants in the family, differing primarily in packaging options and temperature grades. The series is designed to provide nonvolatile storage with RAM-like performance characteristics.

Memory IC Replacement Considerations

Direct hardware replacement for serial I2C EEPROMs with identical pinouts. Verify that the host controller supports the required I2C timing parameters. Ensure voltage levels match the 2.7 V to 3.65 V operating range.
