CY7C4231-25JC

FIFOs Memory Overview

The CY7C4231-25JC is a synchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a storage capacity of 2K x 9 bits, providing a total memory density of 18 kilobits. The component supports a maximum data rate of 66.7MHz with an access time of 10ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 35mA. The device is housed in a 32-pin PLCC package with dimensions of 11.43mm x 13.97mm. It is designed for surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Synchronous operation with unidirectional bus direction
• Supports programmable flags for status indication
• CMOS technology for low power consumption

FIFOs Memory Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous components
• Temporary data storage in communication protocols

FIFOs Memory Procurement Notes

Verify the specific suffix 'JC' against official Cypress documentation to confirm package type and temperature grade. Ensure compatibility with 4.5V to 5.5V logic levels. Check for RoHS compliance status as older Cypress parts may not meet current environmental standards. Confirm availability through authorized distributors or verified secondary market sources due to potential obsolescence.

FIFOs Memory Selection Notes

Select this component when a small, fast synchronous FIFO is required for 9-bit wide data paths. The 2K depth is suitable for moderate buffering needs. Compare with the CY7C4231-15JCT if faster access times are needed, noting that the -15 variant offers 10ns access at potentially higher speeds. Ensure the system design accommodates the 32-PLCC footprint and standard 5V logic interfaces.

FIFOs Memory Part Context

The CY7C4231 belongs to the CY7C series of low-voltage synchronous FIFOs produced by Cypress Semiconductor. This family includes various depths such as 64, 256, 512, 1K, 2K, 4K, and 8K words. The CY7C4231 specifically addresses the 2K x 9 configuration, offering a balance between capacity and speed for embedded applications requiring reliable data synchronization.

FIFOs Memory Replacement Considerations

The CY7C4231-15JCT is a documented alternative within the same series, offering similar specifications but potentially different timing characteristics. Verify pinout compatibility and electrical parameters before substitution. Other members of the CY7C42xx family may serve as functional replacements if depth and width requirements align.
