Product Summary
The ADMC330BSTZ is a low cost single chip DSP microcontroller optimized for stand alone ac motor control applications. The ADMC330BSTZ is based on a 20 MHz fixed-point DSP core (ADSP-2171) and a set of motor control peripherals including seven analog input channels and a 12-bit three-phase PWM generator. The ADMC330BSTZ has two auxiliary 8-bit PWM channels and adds expansion capability through the serial ports and an 8-bit digital I/O port. The ADMC330BSTZ 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.
