VM2 Embedded Controller Family
VM2 is a family of industrial microcontrollers developed for use in
- Machine automation
- Process control
- Scientific and medical instruments
- Portable and hand-held devices
- Automatic test equipment (ATE)
and other embedded controller applications.
The VM2 controller family is backed up by free design and programming tools.
Example Circuit Designs
- Colour Display support
- File systems in internal Flash, SRAM, SD cards and USB Flash drives
- Internet protocols
- Web servers, FTP and email
- Analogue and Digital I/O
- Audio output
- Encryption and Security
The VM2 plugs into the main PCB of your application
to control all your user interface and I/O devices.
Or, if you don’t want to develop your own application PCB we
supply a range of products you can plug together to build your application.
We supply a range of starter kits so you can evaluate the VM2 for your application.
The VM2 Family
There are two standard units in the VM2 embedded controller family, and variations available on special order. All members of the VM2 family are plug-in and pin-compatible.
VM2 (Standard unit)
The standard VM2 embedded controller has 1MB of SRAM, 8MB of flash and a rich set of I/O.
Instead of a ‘large display’ capability it has 20 extra I/O channels. It can drive smaller displays.
Product code: 5900
VM2-D2 (Adds display driver & more SRAM)
The VM2-D2 adds a driver for large colour displays, e.g. WVGA resolution (800 x 480). It also doubles the SRAM size to 2MB.
Product code: 5920
VML (For low cost designs)
The VM2L is a stripped-down VM2 for low cost designs. Application code size and the SRAM size are 64K Bytes each. Filing systems and graphic displays are not supported.
Not available from stock. Built to order only.
Product code: 5901
VM2 Build Options
The VM2 and VM2-D2 can be built with up to 8MB SRAM. These are not available ex stock, but can be built to order.
VM2 Backup battery
VM2 uses a standard CR2032 Lithium battery to power the Real time clock and retain some settings while not powered. Not all applications require a battery.
