It is pin compatible with these devices. Among the VRS700’s features are 8 PWM outputs, a Watch Dog Timer, bank mapping to permit direct addressing of the 4096 bytes of RAM and a serial port. The VRS700’s hardware features and powerful instruction set make it a versatile and cost-effective controller for a wide range of applications requiring a microcontroller running at 3V. The Flash memory can be programmed using programmers available from Goal Semiconductor or other 3rd party commercial programmers. The VRS700 is available in PLCC-44 and QFP-44 packages in the Industrial Temperature Range.
