摩托罗拉 MVME333S-2 是一款 VMEbus 智能通信控制器，具有六个串行 I/O 端口，可配置为同步或异步以及 RS-232C 或 RS-422 电气协议。板载智能包括 10 MHz 的 MC68010 CPU，带有两个固件插槽，以及用于数据缓冲的 128 Kb 动态 RAM。它具有用于在所有六个通道上实现异步协议的固件（同时在所有通道上双向高达 9600 波特）。此外，在两个通道上还有一个高速双向 DMA，用于高达 1 Mb/s 的同步协议。
【英文介绍】
Features:
6 serial I/O ports
Supports synchronous and asynchronous communication
128 Kb of dynamic RAM
Dual channel high-speed two-way DMA
The MOTOROLA MVME333S-2 is a VMEbus intelligent communications controller with six serial I/O ports that can be configured to be synchronous or asynchronous as well as RS-232C or RS-422 electrical protocols. Onboard intelligence includes a 10 MHz MC68010 CPU with two firmware slots, and 128 Kb of dynamic RAM for data buffering. It has firmware for implementing asynchronous protocols on all six channels (up to 9600 baud bidirectional on all channels simultaneously). In addition, there is a high-speed bidirectional DMA on both channels for synchronization protocols up to 1 Mb/s.
