CY7C4201-25AC

FIFOs Memory Overview

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

FIFOs Memory Feature Summary

• Synchronous first-in-first-out memory architecture for data buffering
• Unidirectional data transfer capability
• Supports programmable flags for status indication

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific suffix '25AC' against official Cypress or Infineon datasheets to confirm pinout compatibility and electrical characteristics. Ensure the 32-TQFP package dimensions match the target PCB footprint. Confirm RoHS compliance status as required by project specifications, noting potential variations in legacy documentation.

FIFOs Memory Selection Notes

Select this component when a small-depth synchronous FIFO is required for unidirectional data flow. The 256x9 organization suits applications needing minimal latency buffering. Verify that the 15ns access time meets the system clock requirements. Consider the TQFP package constraints for thermal management and board space availability.

FIFOs Memory Part Context

This part belongs to the CY7C42xx series of synchronous FIFOs from Cypress Semiconductor. These devices are designed for high-performance data buffering applications. The CY7C4201 variant specifically offers a compact 256-word depth, making it suitable for space-constrained designs requiring reliable synchronous data handling without complex control logic.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the CY7C42xx family, such as different speed grades or package options. Verify pin-to-pin compatibility before substitution. Consult official replacement guides from Infineon Technologies, the current manufacturer, for validated alternatives.
