CY7C462A-25PTC

FIFOs Memory Overview

The CY7C462A-25PTC is an asynchronous FIFO memory component manufactured by Cypress Semiconductor. It features a storage capacity of 16K x 9 bits and operates with a maximum access time of 25ns, corresponding to a clock frequency of 28.5MHz. The device utilizes CMOS technology and is housed in a 28-pin PDIP package. As part of the cascadable family, it supports unidirectional data flow for buffer applications.

FIFOs Memory Feature Summary

• Asynchronous operation allowing independent read and write clocks
• Cascadable architecture supporting expanded memory configurations
• CMOS construction for low power consumption

FIFOs Memory Applications

• Data buffering between different clock domains
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

FIFOs Memory Procurement Notes

Verify the specific suffix 'PTC' confirms the 25ns speed grade and PDIP-28 package type. Ensure compatibility with system voltage requirements and confirm that the asynchronous nature aligns with the target interface design. Cross-reference official datasheets for pinout accuracy.

FIFOs Memory Selection Notes

Select this component when a fixed 16K depth is required without synchronous control overhead. Consider the 25ns latency for timing constraints. Evaluate the PDIP package suitability for the intended PCB assembly method compared to surface-mount alternatives within the same series.

FIFOs Memory Part Context

This part belongs to the CY7C462A series of asynchronous FIFOs. The series offers scalable capacities including 8K, 32K, and 64K depths. The CY7C462A-25PTC specifically represents the 16K configuration with a 25ns performance tier, designed for general-purpose buffering tasks.

FIFOs Memory Replacement Considerations

Check for CY7C462A-15PTC if faster 15ns access is needed. Verify CY7C462A-35PTC for slower, potentially lower-cost options. Ensure any substitute maintains the 16Kx9 depth and asynchronous functionality.
