Overview
Description
The 72V3612 is a 3.3V version of the 723612. Two independent 64 x 36 dual-port SRAM FIFOs on board the chip buffer data in opposite directions. Communication between each port can bypass the FIFOs via two 36-bit mailbox registers. The enables for each port are arranged to provide a simple bi-directional interface between microprocessors and/or buses with synchronous control.
Features
- Supports clock frequencies up to 83 MHz
- Fast access times of 8ns
- Free-running CLKA and CLKB can be asynchronous or coincident
- Mailbox bypass Register for each FIFO
- Programmable Almost-Full and Almost-Empty Flags
- Microprocessor interface control logic
- Passive parity checking on each port
- Available in 132-pin PQF and 120-pin TQFP packages
- Industrial temperature range (–40C +85C) is available
