CY7C466A-10JC

FIFOs Memory Overview

The CY7C466A-10JC is a 64K x 9 asynchronous FIFO memory component manufactured by Infineon Technologies (originally Cypress Semiconductor). It features a 10 ns maximum access time and supports read/write operations at frequencies up to 50 MHz. The device operates on a 5V ± 10% supply voltage with an operating current of 60 mA and standby current of 8 mA. It is housed in a 32-Lead Plastic Leaded Chip Carrier (J65 package) and is rated for commercial ambient temperature ranges from 0°C to +70°C.

FIFOs Memory Feature Summary

• Asynchronous read and write operations allow independent data transfer rates up to 50 MHz.
• Includes Full, Empty, and Half Full status flags to manage data flow and prevent overrun or underrun conditions.
• Supports standalone, width expansion, and depth expansion configurations for flexible system integration.
• Features a retransmit function in standalone mode to facilitate packet data acknowledgment and retransmission.

FIFOs Memory Applications

• Buffering data streams between components operating at different clock speeds.
• Packet processing systems requiring data retransmission capabilities.
• High-speed interface adapters utilizing cascading FIFO structures.
• Communication equipment managing asynchronous data transfers.

FIFOs Memory Procurement Notes

Verify the specific suffix 'JC' corresponds to the Commercial temperature range and J65 32-Lead PLCC package. Confirm that the source document identifies this as a legacy product originally from Cypress Semiconductor, now part of Infineon. Ensure compatibility with 5V logic levels and check for any end-of-life notices regarding availability.

FIFOs Memory Selection Notes

Select this component when a 64K depth and 9-bit width are required for asynchronous buffering. The 10 ns speed grade suits applications needing 50 MHz throughput. Consider the J65 package constraints if PCB space allows for leaded chip carriers. Evaluate expansion needs; this device supports cascading for greater depth or width but lacks bank switching found in synchronous SRAMs.

FIFOs Memory Part Context

This part belongs to the CY7C46xA family of asynchronous, cascadable FIFOs, which also includes 8K, 16K, and 32K variants. These devices utilize advanced CMOS technology and are designed for high-speed data buffering. They are pin-compatible with density upgrades within the family and offer functional equivalence to older IDT720x series parts.

FIFOs Memory Replacement Considerations

The datasheet notes functional equivalence to IDT7208. Verify pinout and electrical characteristics against specific IDT7208 variants before substitution. No other direct substitute part numbers are explicitly listed in the provided documentation.
