The VCU1220 is a fully programmable, ruggedized embedded control module intended for use in a variety of system and vehicle control applications. User applications are given full access to system resources and peripherals with an easy-to-use hardware abstraction written in C++.

A number of input and output stages provide the discrete interface with the larger system. Two CAN 2.0B ports and one RS485 port are fully configurable to allow for communication with other devices. Each port includes a software selectable termination resistor for maximum system flexibility. User applications are programmed onto the device using the CAN1 or CAN2 interface and the VCU1220 bootloader, which can be accessed via the Stafl Systems Bootloader Utility.
