CY14B101LA-ZS20XIT

Memory IC Overview

The CY14B101LA-ZS20XIT is a 1-Mbit (128 K × 8) nonvolatile static RAM utilizing QuantumTrap technology. It operates within a voltage range of 2.7 V to 3.6 V and supports an industrial temperature range of -40 °C to +85 °C. The device features a 20 ns access time and is housed in a 44-pin Thin Small Outline Package Type II. It provides infinite read/write cycles for the SRAM array and up to 1 million STORE cycles to the nonvolatile elements, with a data retention capability of 20 years.

Memory IC Feature Summary

• Integrates fast static RAM with embedded QuantumTrap nonvolatile memory cells for data preservation.
• Supports automatic STORE operations upon power-down using a small external capacitor on the VCAP pin.
• Enables software-controlled STORE and RECALL sequences via specific address patterns.
• Includes hardware STORE control through the HSB pin for system-initiated data saving.

Memory IC Applications

• Industrial control systems requiring persistent configuration storage
• Embedded applications needing reliable data retention during power interruptions
• Systems demanding high endurance for frequent nonvolatile write operations

Memory IC Procurement Notes

Verify component authenticity against Infineon official documentation. Confirm package integrity and moisture sensitivity handling procedures prior to assembly. Ensure the VCAP capacitor value falls within the specified minimum and maximum limits to guarantee successful AutoStore functionality. Check for any product discontinuance notifications or lifecycle status updates before finalizing procurement plans.

Memory IC Selection Notes

Select this part when a parallel interface nvSRAM with 128 K x 8 organization is required. The 20 ns speed grade suits high-performance applications compared to slower variants. The 44-pin TSOP II package is suitable for surface-mount designs with specific footprint constraints. Consider the single 3 V supply requirement and industrial temperature rating for environmental compatibility.

Memory IC Part Context

This component belongs to the CY14B101LA family of 1-Mbit nvSRAM devices. It shares architectural similarities with the CY14B101NA, which offers a 64 K x 16 organization. Both families utilize the same QuantumTrap technology and support identical control mechanisms for STORE and RECALL operations across various package options including SOIC, SSOP, and FBGA.

Memory IC Replacement Considerations

Direct substitutes include other CY14B101LA variants with different access times or packages, such as CY14B101LA-SZ25XIT or CY14B101LA-SZ45XIT. Cross-family replacements like the CY14B101NA require adaptation for the 16-bit data bus width. Verify pinout compatibility and electrical characteristics before substituting.
