GENERAL DESCRIPTION

The ADMC(F)340 is a low cost, single-chip DSP-based

controller suitable for permanent magnet synchronous, ac

induction, switched reluctance, and brushless dc motors. The

ADMC(F)340 integrates a 20 MHz, fixed-point DSP core with

a complete set of motor control and system peripherals for fast,

efficient development of motor controllers.

The DSP core of the ADMC(F)340 is completely code compatible

with the ADSP-21xx DSP family and combines three computa-

tional units, data address generators, and a program sequencer.

The computational units comprise an ALU, a multiplier/accumu-

lator (MAC), and a barrel shifter. There are special instructions

for bit manipulation, multiplication (x squared), biased rounding,

and global interrupt masking. The system peripherals are the

power-on reset circuit (POR), the watchdog timer, and two

synchronous serial ports. The serial ports are configurable

and double buffered, with hardware support for UART, SCI,

and SPI port emulation. The ADMC(F)340 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 ADMCxx family

parts. The program 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 ADMC(F)340 provide a 12-bit

analog data acquisition system with 13 analog input channels,

three dedicated ISENSE functions (combining internal amplifi-

cation, 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

ADMC(F)340 also contains two 16-bit auxiliary PWM timers

and 25 lines of programmable digital I/O.

Several functions, such as the auxiliary PWM and the serial

communication ports, are multiplexed with the nine PORTA

(9, PIO) programmable input/output (PIO) pins. The other 16

programmable digital I/O pins are dedicated. The pin functions

can be independently selected to allow maximum flexibility

for different applications.
