DOMINION Electronics has released Rabbit Semiconductors’ PowerCore range of microprocessor core modules. PowerCores are designed to facilitate rapid development and implementation of embedded systems.

They are powered by eight-bit Rabbit microprocessors with a C-friendly instruction set designed for use with the Dynamic C development system. The PowerCore mounts on a user-designed motherboard and acts as the controlling microprocessor for the user's system. PowerCores with onboard power supplies can also provide power to the motherboard. They give designers a complete package for control and communication. With available on-board power supply, analogue features and a Rabbit 3000 microprocessor, the PowerCore bridges the gap between microcontrollers and single board computers.

It reduces the effort required to build embedded control applications. It is available with 1MB Flash, 1MB SRAM and 1MB Serial Flash as well as five serial ports, 39 I/O, a real time clock and Ethernet.

Onboard analogue features include a ramp generator. Coupled with inexpensive comparators and the pulse capture capabilities of the Rabbit 3000 microprocessor, this allows measurement of analogue voltages for applications such as temperature measurement using the on-board thermistor. Onboard ac crossover detection is available for triac applications.

The Ethernet port frees designers from the limitations of serial-port communications and control and also permits instant local or worldwide connectivity using low-cost networking hardware. Embedded systems using the Ethernet RabbitCore module can be controlled and monitored (as well as programmed and debugged when using appropriate accessory hardware) across any network or the internet.
