This datasheet also covers the CY7C408A-15DMB variant, as both devices belong to the same 64 x 9 cascadable fifo family and are provided as variant models within a single manufacturer datasheet.
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.
Key Features
64 x 8 and 64 x 9 first-in first-out (FIFO) buffer memory.
35-MHz shift in and shift out rates.
Almost Full/Almost Empty and Half Full flags.
Dual-port RAM architecture.
Fast (50-ns) bubble-through.
Independent asynchronous inputs and outputs.
Output enable (CY7C408A).
Expandable in word width and FIFO depth.
5V ± 10% supply.
TTL complete.
Capable of withstanding greater than 2001V electro-
static.
Note: The manufacturer provides a single datasheet file (CY7C408A-15DMB_CypressSemiconductor.pdf) that lists specifications for multiple related part numbers.
