CY7C460-15JI

FIFOs Memory Overview

The CY7C460-15JI is an asynchronous FIFO memory component manufactured by Cypress Semiconductor Corp. It features a storage capacity of 8K x 9 bits, providing a total density of 72 kilobits. The device supports a maximum access time of 15 nanoseconds and operates with a cycle time of 25 nanoseconds. It utilizes CMOS technology and is housed in a 32-pin Plastic Quad Flatpack (PQCC) package, specifically identified as LCC-32. The unit includes retransmit capability and three-state outputs for flexible bus interfacing.

FIFOs Memory Feature Summary

• Asynchronous operation mode for independent clock domains
• Retransmit capability to handle data collisions
• Three-state output buffers for bus sharing

FIFOs Memory Applications

• Data buffering between asynchronous systems
• Clock domain crossing interfaces
• Protocol conversion buffers

FIFOs Memory Procurement Notes

Verify the specific manufacturer origin, as Infineon has listed this part number in distribution channels. Confirm the package type matches the 32-pin PQCC/LCC-32 specification. Check lifecycle status, as some sources indicate obsolete or last-time-buy conditions. Ensure the voltage range aligns with system requirements before integration.

FIFOs Memory Selection Notes

Select this component when a small-depth, narrow-width asynchronous buffer is required. The 15ns access time suits moderate-speed applications. Consider the 32-pin package constraints for PCB layout. Verify compatibility with system voltage levels, noting potential variations in supply voltage specifications across different manufacturer datasheets.

FIFOs Memory Part Context

This part belongs to the CY7C46x family of asynchronous FIFOs. It shares functional similarities with other members like the CY7C466A but differs in depth and width configurations. The series is characterized by CMOS construction and standard logic interface protocols suitable for general-purpose digital buffering tasks.
