CY14E512Q1A-SXI

Memory IC Overview

The CY14E512Q1A-SXI is a 512-Kbit (64K × 8) SPI nvSRAM utilizing QuantumTrap technology. It operates within a voltage range of 4.5 V to 5.5 V and supports industrial temperature ranges. The device features a high-speed serial peripheral interface capable of 40-MHz standard access and up to 104-MHz fast read speeds. It provides infinite SRAM write cycles and 1 million STORE cycles to nonvolatile elements, with data retention specified at 20 years at 85 °C.

Memory IC Feature Summary

• Integrates infinite-cycle SRAM with highly reliable QuantumTrap nonvolatile storage for secure data preservation.
• Supports automatic data storage during power-down events using an external capacitor on the VCAP pin.
• Enables hardware and software write protection mechanisms including block protection for specific memory segments.
• Provides flexible STORE and RECALL initiation through SPI instructions or hardware pins.

Memory IC Applications

• Industrial control systems requiring persistent configuration data
• Automotive electronics needing reliable nonvolatile memory
• IoT devices with frequent write cycles and power loss scenarios

Memory IC Procurement Notes

Verify the specific suffix 'SXI' against official Infineon ordering guides to confirm package type and tape/reel specifications. Ensure compatibility with the 4.5 V to 5.5 V operating voltage range required by the E-series designation. Confirm that the selected variant matches the required pinout, as Q1A variants lack the HSB pin found in other configurations.

Memory IC Selection Notes

Select this component when infinite write endurance is critical compared to traditional EEPROMs. The Q1A variant is suitable for designs where AutoStore is managed via software STORE instructions rather than hardware capacitors. Ensure the system can support the required SPI clock speeds and voltage levels for reliable operation.

Memory IC Part Context

This part belongs to the CY14X512Q family of 512-Kbit SPI nvSRAMs. It shares core architecture with CY14C512Q and CY14B512Q but differs in operating voltage and feature availability. The Q1A suffix denotes a specific pin configuration without the HSB pin or AutoStore capacitor support, distinguishing it from Q2A and Q3A variants.

Memory IC Replacement Considerations

Direct replacements include CY14E512Q2A-SXI and CY14E512Q3A-SXI. Note that these alternatives include additional features such as the HSB pin and AutoStore capability, which may require schematic adjustments if not utilized.

Memory IC FAQ

Does the CY14E512Q1A support AutoStore?

No, the CY14E512Q1A does not support AutoStore. Data must be secured using Software STORE instructions initiated via the SPI interface.

How is write protection implemented?

Write protection is available through the WP pin for hardware protection and via the Write Disable instruction for software protection, including block protection options.
