ADMCF328

GENERAL DESCRIPTION
The ADMCF328 is a low cost, single-chip DSP-based control-
ler, suitable for permanent magnet synchronous motors, and
brushless dc motors. The ADMCF328 integrates a 20 MIPS,
xed-point DSP core with a complete set of motor control and
system peripherals that permits fast, efcient development of
motor controllers.
The DSP core of the ADMCF328 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 congurable, and double buffered, with hardware sup-
port for UART and SCI port emulation.
The ADMCF328 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 pro-
gram memory ROM contains a monitor function as well as
useful routines for erasing, programming, and verifying the
flash memory.
The motor control peripherals of the ADMCF328 provide a 12-bit
analog data acquisition system with ve analog input channels,
one dedicated ISENSE function (combining internal amplication,
sampling and overcurrent PWM shutdown features), 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
ADMCF328 also contains two auxiliary PWM outputs and
nine lines of digital I/O.
Because the ADMCF328 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.
