VMOD-32
MC68332 intelligent VMEbus I/O controller

Description

The VMOD-32 is a powerful intelligent I/O controller based on the MC68332 MCU.

Because of the modularity of the mezzanine I/O bus concept MODULbus, the VMOD-32 is fully

compatible to the higher grade VMOD-40 and VMOD-60 VMEbus computer boards.

The VMOD-32 is designed for cost effective solutions ranging from I/O controller to single board

computer applications. Due to the MODULbus, the number of customer specific areas of use and

options is almost inexhaustible.

The standard version of the VMOD-32 is provided with 1 MByte of DRAM, 4 MByte can be equipped

as maximum. SRAM is available as an option.

All versions of the VMOD-32 carry an RTC with on-chip 2 Kbytes SRAM; a battery backup circuit

prevents data loss during power failure. A JEDEC socket for an 8Bit EPROM offers a maximum size

of 1 MByte for firmware and/or operating system memory for the MC68332 MCU. It is possible to boot

either from the Flash PROM or from the EPROM.

A serial interface(RS232) is available on the front panel sub-D connector and can be used as console

port or data transfer line.

Additionally, a CAN fieldbus interface is available as an option. This offers basic CAN specifications

according to ISO/DIS 11898 with high speed CAN using the 82C200 controller. The CAN option on the

VMOD-32 is supported by the ICANOS CAN operating system and CAL and CANopen compatible

software packages.

The monitor software program offers download and start procedures for module tasks allowing

software development in high level languages on a UNIX,, OS-9, VxWorks or other development

system.

The VMOD-32 software environment is fully supported with VxWorks and OS-9 as powerful real time

operating systems.
