CY14ME064Q2B-SXI

Memory IC Overview

The Infineon CY14ME064Q2B-SXI is a 64-Kbit (8K × 8) SPI nvSRAM utilizing QuantumTrap technology. It operates within a voltage range of 4.5 V to 5.5 V and supports SPI clock rates up to 40 MHz with zero cycle delay for read/write operations. The device features infinite SRAM write cycles and 1 million STORE cycles to nonvolatile elements, ensuring 20 years of data retention at 85°C. It includes AutoStore functionality powered by an external capacitor on the VCAP pin and offers hardware/software write protection.

Memory IC Feature Summary

Integrates QuantumTrap nonvolatile memory cells with SRAM for infinite read/write endurance and high reliability.
Supports automatic data storage during power-down via AutoStore using an external capacitor on the VCAP pin.
Provides flexible write protection through a dedicated WP pin and software block protection mechanisms.

Memory IC Applications

Industrial control systems requiring frequent data logging
Automotive electronics needing reliable nonvolatile storage
Smart metering applications with extended temperature requirements

Memory IC Procurement Notes

Verify component authenticity against official Infineon documentation due to discontinuation status. Confirm package integrity and RoHS compliance upon receipt. Ensure proper handling of moisture-sensitive devices as indicated in datasheet specifications. Cross-reference ordering codes carefully to match exact voltage and feature variants.

Memory IC Selection Notes

Select this variant specifically for 5V operation requirements, distinguishing it from the 3V CY14MB064Q2B model. The Q2B suffix indicates support for AutoStore and presence of the VCAP pin, unlike the Q1B version. Ensure circuit design accommodates the VCAP capacitor for power-loss data preservation.

Memory IC Part Context

This component belongs to the CY14MX064Q family of serial nvSRAMs developed originally by Cypress Semiconductor and now managed by Infineon Technologies. The product line combines the speed of SRAM with the persistence of nonvolatile memory, targeting applications where traditional EEPROMs are too slow or have limited endurance.
