Description:

The MC2000-332 is physically smaller than an SBC2000 yet has all the power as well as an optional A/D connector. The MC2000-332 has just the pins for the port connectors, without the actual ports. hat way the board remains very small and you can add the ports you need without taking up any more space than you have to.

The development kits for this board contain our MC-2000 Development Platform that attaches to the MC2000-332 and provides all the ports for development purposes. Vesta Basic and C development environments are fully supported.

Initial program execution begins in 8 bit wide boot ROM. Execution can be transferred to 16 bit wide flash memory for faster execution or 16 bit wide no wait state battery backable RAM for maximum performance.

The integral TPU supports special time related functions such as PWM generation, quadrature decoding, asynchronous serial transfer, pulse generation, input time stamp capture and period measurement. Any TPU channel can generate an interrupt on positive or negative input transitions. 8 A/D, 12 DIO, 10 TPU channels and 7 interrupts are available.

The system clock rate can be changed under program control to minimize power consumption without interrupting operation. A low-power STOP mode is also available. Additionally, the MC2000-332 can turn itself off completely, reducing supply current to zero, and then reactivate itself at a preprogrammed time. Off-board peripherals are supported by the VAST network and one reconfigurable asynchronous serial channel.
