CY62256LL-70ZXI

Memory IC Overview

The CY62256LL-70ZXI is a 256Kb (32K x 8) asynchronous static RAM manufactured by Infineon Technologies. It features a 70 ns access time and operates within a 4.5V to 5.5V voltage range. The component utilizes a 28-lead Thin Small Outline Package (TSOP-1). Designed for industrial applications, it supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum active supply current of 50 mA and a standby current of up to 10 µA.

Memory IC Feature Summary

• Features automatic power-down when deselected to minimize standby consumption
• Provides TTL-compatible inputs and outputs for system integration
• Supports easy memory expansion through dedicated chip enable and output enable controls

Memory IC Applications

• Industrial control systems requiring volatile data retention
• Embedded memory solutions in consumer electronics
• Automotive electronic modules with extended temperature requirements

Memory IC Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and lead-free status. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with your design specifications. Ensure compatibility with 5V logic levels before procurement.

Memory IC Selection Notes

Select this component for designs requiring low-power SRAM with industrial temperature resilience. Compare the 70 ns speed against faster variants if performance is critical. Verify that the TSOP-1 footprint fits the PCB layout constraints compared to SOIC or DIP alternatives.

Memory IC Part Context

This device belongs to the CY62256 family of high-performance CMOS static RAMs. The LL designation indicates a low-power variant optimized for reduced active and standby currents. The ZXI suffix specifically denotes a lead-free version housed in a standard 28-lead TSOP package.

Memory IC Replacement Considerations

CY62256LL-70ZI serves as a non-lead-free equivalent within the same series.
