VM2 Embedded Controller Family

VM2 Controllers

VM2D Embedded Controller

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.

Design resources

The VM2 controller family is backed up by free design and programming resources.

Further capabilities...

Application Boards

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.

Starter Kits

We supply a range of starter kits so you can evaluate the VM2 for your application.

The VM2 Family

Standard VM2

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.

+ Display driver, extra SRAM

The VM2-D2 adds a driver for colour displays, e.g. WVGA resolution (800 x 480) and larger.

VM2-D2 also doubles the SRAM size to 2MB.

Upto 8MB SRAM

The VM2 and VM2-D2 can be built with upto 8MB SRAM. These are not available ex stock, but can be built to order.

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.
