CY62146GSL-45ZSXI

Overview

The CY62146GSL-45ZSXI is a 4 Mbit (256K x 16) asynchronous static random-access memory from Infineon's MoBL SRAM family. It features a parallel interface with a 45 ns access time, operating within a voltage range of 2.2 V to 3.6 V and an industrial temperature range of -40 °C to +85 °C. The component utilizes a TSOP-44 surface-mount package with Ni/Pd/Au lead finishes, supporting peak reflow temperatures up to 260 °C.

Feature Summary

• Asynchronous parallel interface for direct system integration
• Industrial-grade reliability across extended temperature ranges
• Low-power operation optimized for battery-backed applications

Applications

• Battery-backed data storage systems
• Industrial control logic caching
• Embedded system configuration memory

Procurement Notes

Verify the exact suffix 'GSL' against official Infineon documentation, as standard listings often utilize 'ESL' or 'EV30LL'. Confirm RoHS compliance status and humidity sensitivity classification prior to ordering. Ensure supply chain partners provide valid traceability documents for industrial grade components.

Selection Notes

Select this part for designs requiring 4 Mbit capacity with 16-bit word width in compact TSOP packages. Compare against CY62146ESL variants for pin compatibility and power specifications. Validate voltage margins against the 2.2 V to 3.6 V operational range during system design.

Part Context

This component belongs to the MoBL SRAM series, designed for mobile and low-power embedded applications. It complements other densities like the 1 Mbit CY62128 and 8 Mbit CY62157 families, offering standardized interfaces and packaging options for scalable memory architectures.

Replacement Considerations

CY62146ESL-45ZSXI offers equivalent electrical performance in the same TSOP-44 package. CY62146EV30LL-45ZSXI provides similar functionality with potential voltage variations. Verify pinout and timing parameters before substitution.
