CY7C419-15VXCT

FIFOs Memory Overview

The CY7C419-15VXCT is an asynchronous FIFO memory with a capacity of 256 words by 9 bits. It features a maximum access time of 15 ns and supports independent read and write operations at speeds up to 50 MHz. The device operates on a single 5V supply (4.5V to 5.5V) with a typical operating current of 35 mA. It utilizes a 28-pin SOJ package and functions within the commercial temperature range of 0°C to +70°C.

FIFOs Memory Feature Summary

• Asynchronous first-in first-out buffer memory architecture
• Dual-ported RAM cell for independent read/write operations
• Retransmit capability in standalone configurations
• Expandable in width via dedicated expansion pins

FIFOs Memory Applications

• Data buffering between asynchronous systems
• Packet transfer applications requiring retransmit functionality
• Interface bridging with varying data rates
• System synchronization buffers

FIFOs Memory Procurement Notes

Verify the specific suffix VXCT corresponds to the 28-pin SOJ package and commercial temperature grade. Confirm RoHS compliance status as the datasheet indicates Pb-free options are available within the series. Ensure the ordering code matches the required speed grade of 15 ns access time.

FIFOs Memory Selection Notes

Select this component when a 256x9 word depth is required for asynchronous data buffering. The 15 ns speed grade suits applications needing up to 50 MHz throughput. Consider the SOJ package constraints and verify if the standalone or width expansion modes meet system requirements, noting that depth expansion is not supported in this configuration.

FIFOs Memory Part Context

This part belongs to the CY7C419/21/25/29/33 family of asynchronous FIFOs manufactured by Cypress Semiconductor, now part of Infineon Technologies. The family offers depths ranging from 256 to 4096 words, all maintaining a 9-bit width. These devices are designed for high-speed data buffering using advanced CMOS technology.

FIFOs Memory Replacement Considerations

Pin-compatible and functionally equivalent alternatives include IDT7200, AM7200, and their respective variants. Verify voltage levels and package dimensions before substitution.
