Description

The ADMC331BST is a low cost, single-chip DSP-based controller,suitable for ac induction motors, permanent magnet synchronous motors, brushless dc motors, and switched reluctance motors. The ADMC331BST integrates a 26 MIPS, fixed-point DSP core with a complete set of motor control peripherals that permits fast, efficient development of motor controllers.

The DSP core of the ADMC331BST is the ADSP-2171, which is completely code compatible with the ADSP-2100 DSP family and combines three computational units, data address generators and a program sequencer. The computational units comprise an ALU, a multiplier/accumulator (MAC) and a barrel shifter. The ADSP-2171 adds new instructions for bit manipulation,multiplication (X squared), biased rounding and global interrupt masking. In addition, two flexible, double-buffered,bidirectional, synchronous serial ports are included in the ADMC331BST. It provides 2K × 24-bit program memory RAM,2K × 24-bit program memory ROM and 1K × 16-bit data memory RAM. The program and data memory RAM can be boot loaded through the serial port from a Serial ROM (SROM),E2PROM, asynchronous (UART) connection or synchronous connection. The program memory ROM includes a monitor that adds software debugging features through the serial port. In addition, a number of preprogrammed mathematical and motor control functions are included in the program memory ROM.

The motor control peripherals of the ADMC331BST include a 16-bit center-based PWM generation unit that can be used to produce high accuracy PWM signals with minimal processor overhead and seven analog input channels. The device also contains two auxiliary 8-bit PWM channels, a 16-bit watchdog timer and expanded capability through the serial ports and 24-bit digital I/O ports.
