CY14MB064Q2A-SXQT

Memory IC Overview

The CY14MB064Q2A-SXQT is a 64-Kbit (8 K × 8) serial non-volatile SRAM featuring an SPI interface. It integrates a nonvolatile element within each memory cell to retain data without power. The device operates at a frequency of 40 MHz and supports a supply voltage range of 2.7 V to 3.6 V. It is qualified for industrial quality with an extended operating temperature range from -40 °C to +125 °C. The component utilizes AutoStore technology for automatic data preservation.

Memory IC Feature Summary

• Integrates nonvolatile elements in each memory cell for permanent data retention
• Features AutoStore technology for automatic data backup during power loss
• Supports high-speed serial communication via SPI interface

Memory IC Applications

• Industrial control systems requiring persistent configuration storage
• Automotive electronics needing reliable data logging
• Consumer devices with frequent power cycling requirements

Memory IC Procurement Notes

Verify the specific suffix 'SXQT' indicates tape-and-reel packaging when sourcing. Confirm the 'Q2A' designation aligns with the required automotive or industrial qualification standards for your application. Ensure the voltage rating matches your system's 3.3 V nominal supply. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Memory IC Selection Notes

Select this component when non-volatility is critical alongside fast access speeds. The SPI interface reduces pin count compared to parallel alternatives. Consider the extended temperature range for harsh environments. Verify that the 64-Kbit capacity meets your data storage needs without excessive waste. Evaluate the SOIC-8 package constraints against your PCB layout space.

Memory IC Part Context

This part belongs to the Cypress Infineon nvSRAM family, combining SRAM speed with EEPROM-like persistence. It replaces traditional solutions involving separate microcontrollers and flash memory for small data sets. The series is designed for applications where data integrity during unexpected power failures is paramount.

Memory IC Replacement Considerations

Direct substitutes include other CY14MX064Q2A variants with different packaging options such as TSSOP or WSON. Cross-reference with CY14MB064Q2A-SXQ for lead-free equivalents. Ensure interface compatibility when substituting with generic SPI FRAM or Flash devices.
