CY7C419-10JXCT

FIFOs Memory Overview

The CY7C419-10JXCT is a 256 x 9 asynchronous FIFO memory device manufactured by Infineon Technologies. It features a dual-ported RAM cell architecture enabling independent read and write operations at speeds up to 50 MHz. The component supports TTL-compatible logic levels and includes status flags for empty, full, and half-full conditions. It operates within a commercial temperature range of 0°C to +70°C with a supply voltage of 5V ± 10%. The device is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package.

FIFOs Memory Feature Summary

• Asynchronous first-in first-out buffer memory architecture
• Dual-ported RAM cells for independent read/write operations
• TTL compatible input and output logic levels
• Hardware flow control via Empty, Full, and Half Full flags

FIFOs Memory Applications

• Data buffering between asynchronous systems
• Interface bridging between different clock domains
• Packet data transfer applications requiring retransmit capability
• Parallel data expansion in width or depth configurations

FIFOs Memory Procurement Notes

Verify the specific suffix JXCT against official documentation to confirm lead-free packaging and exact speed grade. Confirm that the commercial operating temperature range meets system requirements. Ensure compatibility with existing PLCC footprints during integration.

FIFOs Memory Selection Notes

Select this model for applications requiring 256-word depth and 9-bit word width. Choose based on the required access time and operating temperature range. Consider depth expansion capabilities if larger storage buffers are needed compared to standalone usage.

FIFOs Memory Part Context

This component belongs to the CY7C419/21/25/29/33 family of asynchronous FIFOs. The family offers varying depths from 256 to 4096 words while maintaining consistent pinouts and functionality across speed grades. It utilizes advanced CMOS technology for low power consumption.

FIFOs Memory Replacement Considerations

Pin-compatible and functionally equivalent alternatives include IDT7200, AM7200, and similar devices from other manufacturers. Verify electrical characteristics and timing parameters before substitution.
