The ADMC330 is a low cost single chip DSP microcontroller optimized for stand alone ac motor control applications. The device is based on a 20 MHz fixed-point DSP core (ADSP2171) and a set of motor control peripherals including seven analog input channels and a 12-bit three-phase PWM generator. The device has two auxiliary 8-bit PWM channels and adds expansion capability through the serial ports and an 8-bit digital I/O port. The ADMC330 has internal 2K words program RAM, and 1K words data RAM, which can be loaded from an external device via the serial port. There are also 2K words of internal program ROM, which includes a monitor that adds software debugging features through the serial port. The ADMC330 core combines the ADSP-2100 base architecture (three computational units, data address generators and a program sequencer) with two serial ports, a programmable timer, extensive interrupt capabilities and on-chip program and data memory.
