CY7C4201-15JC

FIFOs Memory Overview

The CY7C4201-15JC is a synchronous FIFO memory integrated circuit manufactured by Cypress Semiconductor Corp. It features a storage capacity of 256 words by 9 bits, providing a total depth of 256 x 9. The device supports unidirectional data transfer with a maximum clock frequency of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 35mA. The component is housed in a 32-pin PLCC package (11.43x13.97mm) and is designed for surface mount installation. It functions reliably within an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Synchronous operation with dedicated read and write clocks for independent domain control
• Unidirectional data flow architecture optimized for specific buffer applications
• Programmable status flags indicating full, empty, and half-full conditions

FIFOs Memory Applications

• Data buffering between asynchronous system domains
• Interface bridging in high-speed digital communication systems
• Temporary data storage in embedded processing architectures

FIFOs Memory Procurement Notes

Verify the exact suffix 'JC' corresponds to the 32-PLCC package and 10ns speed grade. Confirm RoHS compliance status as older Cypress parts may not meet current environmental standards. Check for obsolescence or lifecycle status before finalizing procurement plans. Ensure voltage levels match the 4.5V to 5.5V requirement of the target system design.

FIFOs Memory Selection Notes

Select this part when a small, fast synchronous buffer is required for 9-bit wide data paths. Compare against wider bus options like the CY7C4205 if 18-bit width is needed. Consider the CY7C4241 series for larger 4K depth requirements. Verify that the 32-PLCC footprint fits the PCB layout constraints compared to TQFP alternatives.

FIFOs Memory Part Context

This component belongs to the CY7C42xx family of synchronous FIFOs from Cypress, which offers various depths ranging from 64 to 4K words. The CY7C4201 specifically addresses the 256-word depth segment. It shares architectural similarities with other members like the CY7C4205 but differs in word width and capacity. The family is characterized by CMOS technology and standard logic interfaces.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the same Cypress/Infineon portfolio. Verify electrical compatibility for any cross-manufacturer replacements. No specific public substitute part numbers are confirmed in the provided documentation.
