ADMC201 General Description
The ADMC201 is a motion coprocessor that can be used with either microcontrollers or digital signal processors (DSP). It provides the functionality that is required to implement a digital control system. In a typical application, the DSP or microcontroller performs the control algorithms (position, speed, torque and flux loops) and the ADMC201 provides the necessary motor control functions: analog current data acquisition, vector transformation, digital inputs/outputs, and PWM drive signals.

ADMC300 General Description
The ADMC300 is a single-chip DSP-based controller, suitable for high performance control of ac induction motors, permanent magnet synchronous motors and brushless dc motors. The ADMC300 integrates a 25 MIPS, fixed-point DSP core with a complete set of motor control peripherals that permits fast, efficient development of servo motor controllers.
The DSP core of the ADMC300 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 ADMC300.
The ADMC300 provides 4K × 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 either a serial 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 pre-programmed mathematical and motor control functions are included in the program memory ROM.
The motor control peripherals of the ADMC300 comprise a high performance, five channel ADC system that uses sigmadelta conversion technology offering a typical signal-to-noise ratio (SNR) of 76 dB, equivalent to 12 bits. In addition, a 16-bit center-based PWM generation unit can be used to produce high accuracy PWM signals with minimal processor overhead. The ADMC300 also contains a flexible encoder interface unit for position sensor feedback, two auxiliary PWM outputs, twelve lines of digital I/O, a two-channel event capture system, a 16-bit watchdog timer, a 16-bit interval timer and a programmable interrupt controller that manages all peripheral interrupts.
