CY7C4201-15JXC

FIFOs Memory Overview

The CY7C4201-15JXC is a 256 x 9 synchronous FIFO memory manufactured by Cypress Semiconductor. It features a 10 ns access time and supports clock frequencies up to 66.7 MHz. The device operates on a single 5V supply with an active current of 35 mA. It utilizes a 32-pin Pb-free Plastic Leaded Chip Carrier (PLCC) package.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read and write operations using independent clocks.
• Includes programmable Almost Empty and Almost Full status flags for precise buffer management.
• Features width-expansion capability to increase data bus width across multiple devices.

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific -15 speed grade and JXC leaded package suffix against the official datasheet. Confirm that the commercial temperature range meets system requirements. Ensure pin compatibility with existing IDT72201 designs if applicable.

FIFOs Memory Selection Notes

Select this component for applications requiring 256-word depth and 9-bit width. The -15 variant suits systems needing 66.7 MHz operation. Consider the PLCC package for through-hole mounting or standard surface-mount reflow processes compatible with leaded packages.

FIFOs Memory Part Context

This part belongs to the CY7C42X1 family of high-speed, low-power synchronous FIFOs. It shares architectural similarities with other densities in the series, such as the CY7C4211 and CY7C4221, differing primarily in memory depth while maintaining identical pinouts and control logic.

FIFOs Memory Replacement Considerations

Pin-compatible and functionally equivalent to IDT72201. Verify electrical characteristics against IDT72421 if higher performance is required.
