GENERAL DESCRIPTION
The ADMCF326 is a low cost, single-chip DSP-based controller,
suitable for permanent magnet synchronous motors, ac induction
motors, and brushless dc motors. The ADMCF326 integrates a
20 MIPS, fixed-point DSP core with a complete set of motor
control and system peripherals that permits fast, efficient devel-
opment of motor controllers.
The DSP core of the ADMCF326 is the ADSP-2171, which is
completely code-compatible with the ADSP-21xx 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 (
× squared), biased rounding and global inter-
rupt masking.
The system peripherals are the power-on reset circuit (POR),
the watchdog timer and a synchronous serial port. The serial
port is configurable, and double buffered, with hardware sup-
port for UART and SCI port emulation.
The ADMCF326 provides 512
× 24-bit program memory RAM,
4K
× 24-bit program memory ROM, 4K × 24-bit program
FLASH memory, and 512
× 16-bit data memory RAM. The
user code will be stored and executed from the flash memory.
The program and data memory RAM can be used for dynamic
data storage or can be loaded through the serial port from an
external device as in other ADMCxxx family parts. The program
memory ROM contains a monitor function as well as useful rou-
tines for erasing, programming, and verifying the flash memory.
The motor control peripherals of the ADMCF326 provide a 12-bit
analog data acquisition system with six analog input channels,
and an internal voltage reference. In addition, a three-phase,
16-bit, center-based PWM generation unit can be used to produce
high accuracy PWM signals with minimal processor overhead.
The ADMCF326 also contains two auxiliary PWM outputs
and nine lines of digital I/O.
Because the ADMCF326 has a limited number of pins, functions
such as the auxiliary PWM and the serial communication port
are multiplexed with the nine programmable input/output (PIO)
pins. The pin functions can be independently selected to allow
maximum flexibility for different applications.
