Microcontroller Module ec332 with MC68332 Chip

The ec332 is a powerful microcontroller module which plugs directly in your embedded application. It provides the MC68332 microcontroller with the time processor unit (TPU). The TPU can be used for standard binary I/O purposes, but also for more sophisticated tasks as frequency analyses, PWM Output, Motor Control, Counter/Timer, etc. .
The module provides up to 1 MB Flash-EPROM (0 ws) 16-bit wide and up to 1 MB SRAM (0 ws) 16-bit wide Flash programming on board.A 10 pin debug interface (BDM) can be used to program the external flash-EPROM via debug software. The module is also available for an extended temperature range as an option.
