CY7C4271V-10JXC

Overview

The CY7C4271V-10JXC is a 1-Mbit (128K x 8) asynchronous static random-access memory manufactured by Infineon Technologies. It features a 10 ns access time and operates within a voltage range of 3.0 V to 3.6 V, with a maximum supply current of 60 mA. The device utilizes a parallel interface and is housed in a TSOP-48 surface-mount package. Designed for industrial applications, it supports a temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation providing fast read access times
• Low-voltage CMOS technology for reduced power consumption
• Industrial-grade reliability across extended temperature ranges

Applications

• Industrial control systems requiring non-volatile-like speed
• Embedded storage in telecommunications equipment
• Data buffering in consumer electronics

Procurement Notes

Verify the specific suffix JXC against official Infineon documentation to confirm the exact package type and lead-free status. Confirm availability as this component may be subject to lifecycle changes or discontinuation. Ensure compatibility with existing board designs regarding pinout and voltage levels before procurement.

Selection Notes

Select this part when a 1-Mbit capacity with 10 ns speed is required in a TSOP-48 form factor. Consider the 3.3V operating voltage and industrial temperature rating. Evaluate alternatives if higher density or lower power modes are needed, ensuring the replacement matches the interface and physical footprint requirements.

Part Context

This component belongs to Infineon's Fast SRAM family, designed for high-performance data storage. It complements other devices in the series offering varying densities and speeds. The asynchronous nature distinguishes it from synchronous SRAMs, making it suitable for simple bus interfaces without complex clocking requirements.

Replacement Considerations

Check for direct replacements such as the CY7C4271V-10BZXC for different packaging options. Verify functional equivalence with other 128K x 8 SRAMs from Infineon or third-party manufacturers, ensuring timing parameters and voltage specifications align.
