CY7C4201-15JXCT

FIFOs Memory Overview

The CY7C4201-15JXCT is a 256 x 9 synchronous FIFO memory manufactured by Infineon Technologies. It features independent read and write clocks, supporting simultaneous asynchronous operations up to 66.7 MHz. The device includes programmable Almost Empty and Almost Full flags, TTL-compatible inputs, and width expansion capabilities. It operates on a single 5V supply with commercial temperature range support.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read/write operations via independent clock domains
• Features programmable status flags for precise buffer level monitoring
• Enables data bus width expansion through parallel device configuration

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific suffix JXC indicates a lead-free (Pb-free) plastic leaded chip carrier package. Confirm the -15 speed grade corresponds to the 66.7 MHz maximum frequency specification. Ensure the component meets the required commercial operating temperature range of 0°C to +70°C for the intended application environment.

FIFOs Memory Selection Notes

Select this component when a 256-word depth with a 9-bit word width is required. Choose this part if independent read and write clocking is necessary for asynchronous domain crossing. Consider this option for applications requiring programmable flag thresholds to optimize system throughput and prevent overflow or underflow conditions.

FIFOs Memory Part Context

This component belongs to the CY7C42X1 family of high-speed, low-power synchronous FIFO memories. The family offers various densities ranging from 64 to 8K words, all sharing a common 9-bit data bus architecture. These devices are designed for efficient data buffering in digital signal processing and communication interfaces.
