CY15V102QSN-108SXIT

Memory IC Overview

The Infineon CY15V102QSN-108SXIT is a 2-Mbit ferroelectric RAM (F-RAM) organized as 256K x 8 bits. It features a serial quad SPI interface supporting up to 108 MHz SDR and 54 MHz DDR clock frequencies. The device operates within a voltage range of 1.71 V to 1.89 V and supports an industrial temperature range of –40°C to +85°C. Packaged in an 8-pin SOIC, it offers virtually unlimited endurance of 10^14 read/write cycles and 151-year data retention.

Memory IC Feature Summary

• Instant non-volatile write technology eliminates write delays and polling requirements.
• Integrated ECC and CRC logic for enhanced data integrity and error detection.
• Supports Execute-in-Place (XIP) for direct code execution from memory.
• Includes dedicated special sector with content surviving multiple reflow cycles.

Memory IC Applications

• Data collection systems requiring frequent rapid writes
• Industrial control applications demanding high endurance
• Embedded systems needing instant non-volatile storage

Memory IC Procurement Notes

Verify the specific suffix 'I' indicates tape and reel packaging when ordering. Confirm the 'V' designation matches the required 1.71 V to 1.89 V supply voltage range for the target application. Ensure compatibility with the industrial temperature grade specifications before finalizing procurement.

Memory IC Selection Notes

Select this component for applications prioritizing write speed and endurance over density. The low-voltage variant suits power-constrained designs. Verify that the system controller supports the required SPI modes and clock speeds. Consider the 8-pin package constraints for PCB layout and thermal management.

Memory IC Part Context

This part belongs to the EXCELON™ Ultra F-RAM family, designed to replace serial flash and EEPROM in high-performance applications. It combines non-volatility with RAM-like write speeds. The series emphasizes reliability through advanced ferroelectric processes and robust data protection mechanisms.

Memory IC Replacement Considerations

Check pinout compatibility with existing serial flash or EEPROM footprints. Verify voltage level translation if the host system operates outside the 1.71 V to 1.89 V range. Ensure software drivers support the specific command set and register configurations of this F-RAM device.
