CY7C421-10VC

FIFOs Memory Overview

The CY7C421-10VC is a synchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a storage organization of 512 words by 9 bits, providing a total capacity of 4608 bits. The component supports a maximum data rate of 50 MHz with an access time of 10 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is designed for surface-mount installation in a 32-pin PLCC package.

FIFOs Memory Feature Summary

• Synchronous single-direction bus architecture
• Supports depth and width expansion
• Programmable flag support

FIFOs Memory Applications

• High-speed data buffering in digital systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage

FIFOs Memory Procurement Notes

Verify the specific suffix 'VC' against official Cypress documentation to confirm package type and temperature range. Ensure compatibility with 5V logic levels and check RoHS compliance status as older variants may not meet current environmental standards. Confirm availability through authorized distributors given potential end-of-life status.

FIFOs Memory Selection Notes

Select this component when a 512x9 synchronous FIFO is required with 10ns performance. Compare against the CY7C421-10JC if a different package such as PLCC is preferred. Consider the CY7C421-40VCR for slower applications requiring SOJ packaging. Verify pinout compatibility during PCB layout design.

FIFOs Memory Part Context

This part belongs to the CY7C series of memory products from Cypress Semiconductor. It is distinct from the CY7C1021 SRAM and CY7C197 SRAM lines. The CY7C421 family specifically addresses First-In-First-Out memory needs for high-throughput applications requiring deterministic latency.
