CY7C4201-25AI

FIFOs Memory Overview

The CY7C4201-25AI is a synchronous FIFO memory integrated circuit manufactured by Cypress Semiconductor Corp. It features a storage capacity of 256 x 9 bits and operates with a data rate of 40MHz. The device has an access time of 15ns and supports unidirectional bus direction. It is housed in a 32-TQFP package (7x7) and requires a supply voltage between 4.5 V and 5.5 V. Maximum supply current is 35mA, and it functions within a temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture for reliable data buffering
• Unidirectional bus interface simplifies system integration
• Programmable flags support status monitoring

FIFOs Memory Applications

• High-speed data buffering in digital systems
• Interface bridging between asynchronous components
• Data acquisition systems requiring temporary storage

FIFOs Memory Procurement Notes

Verify the specific suffix 'AI' corresponds to the 32-TQFP package and commercial temperature grade. Confirm RoHS compliance status as older Cypress parts may not meet current regulations. Ensure the supplier provides valid traceability documentation for this discontinued or legacy component series.

FIFOs Memory Selection Notes

Select this part when a 256x9 depth is required with 15ns latency. Compare against the CY7C421 series for larger capacities. Verify voltage compatibility with the 4.5V to 5.5V range. Check pinout compatibility if replacing similar TQFP FIFOs.

FIFOs Memory Part Context

Part of the CY7C42xx family of synchronous FIFOs from Cypress. This series offers various depths and speeds. The CY7C4201 variant specifically targets applications needing moderate density with fast access times in a compact surface-mount package.

FIFOs Memory Replacement Considerations

Check for direct substitutes like CY7C4201-15JC or CY7C4201-25AC if package or speed variations are acceptable. Verify pin-to-pin compatibility before substitution.
