Features:

6 serial I/O ports

Supports synchronous and asynchronous communication

128 Kb of dynamic RAM

High-speed bi-directional DMA on two channels

The Motorola MVME333S-2 is a VMEbus intelligent communications controller with six serial I/O ports that can be configured for synchronous or www.cniacs.com asynchronous and RS-232C or RS-422 electrical protocols.

On-board intelligence includes the MC68010 10 MHz CPU with two slots for firmware and 128 Kb of dynamic RAM for data buffering.

It has firmware for asynchronous protocols on all six channels (up to 9600 baud in both directions on all channels simultaneously).

In addition, there is a high-speed bi-directional DMA for synchronous protocols up to 1 Mb/s on two channels.
