CY7C4241-15JC

FIFOs Memory Overview

The CY7C4241-15JC is a synchronous FIFO memory with a 4K x 9 organization, housed in a 32-pin PLCC package. It supports a maximum frequency of 66.7 MHz and features a 10 ns access time. The device operates on a 4.5 V to 5.5 V supply with a maximum active current of 35 mA. It includes programmable Almost Empty and Almost Full flags, TTL-compatible inputs, and independent read/write clocks for asynchronous operation.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read and write operations using independent clock domains.
• Features programmable Almost Empty and Almost Full status flags for precise buffer management.
• Includes width-expansion capability to increase data bus width by connecting multiple devices.
• Provides center power and ground pins to reduce noise and improve signal integrity.

FIFOs Memory Applications

• High-speed data acquisition systems
• Multiprocessor interfaces
• Communications buffering

FIFOs Memory Procurement Notes

Verify the specific suffix 'JC' confirms the commercial temperature range (0°C to +70°C) and 32-pin PLCC package. Confirm RoHS compliance status as older Cypress parts may not meet current standards. Check for end-of-life or obsolescence notices from Infineon or authorized distributors before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when a 4K depth and 9-bit width are required for synchronous buffering. Ensure the system design accommodates the 4.5 V to 5.5 V supply voltage. Consider the 32-pin PLCC package constraints for PCB layout. Verify that the 66.7 MHz speed meets the application's timing requirements compared to faster -10 speed grades.

FIFOs Memory Part Context

This part belongs to the CY7C42X1 family of high-speed, low-power synchronous FIFOs manufactured by Cypress Semiconductor. The family offers various densities ranging from 64x9 to 8Kx9. The CY7C4241 specifically provides 4K words of storage. These devices are pin-compatible with IDT722X1 series FIFOs, facilitating direct replacements in existing designs.

FIFOs Memory Replacement Considerations

Pin-compatible and functionally equivalent substitutes include IDT72421, 72201, 72211, 72221, 72231, and 72241. Verify that any replacement matches the 4K x 9 density and 10 ns access time specifications.
