CY7C408A Datasheet 64 X 8 Cascadable Fifo

Manufacturer: Cypress (now Infineon)

Overview: 1CY 7C40 9A CY7C408A CY7C409A 64 x 8 Cascadable FIFO 64 x 9 Cascadable.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The CY7C408A and CY7C409A are 64-word deep by 8- or 9-bit wide first-in first-out (FIFO) buffer memories.

In addition to the industry-standard handshaking signals, almost full/almost empty (AFE) and half-full (HF) flags are provided.

AFE is HIGH when the FIFO is almost full or almost empty, otherwise AFE is LOW.

Key Features
