ADMC401

Single-Chip, High Performance Embedded DSP Controller

Features

Benefits

• High resolution integrated 12-bit multi-chan-

nel ADC (> 70 dB SNR)

– 8 channel simultaneous sampling (8 chan-

nels converted in < 2µ sec)

– Integrated precision voltage reference

• Three phase 16-bit PWM generation unit

• Two 8-bit auxiliary PWM outputs

• 26 MIPS fixed-point DSP core

– 2K x 24-bit program memory RAM

– 2K x 24-bit program memory ROM

– 1K x 16-bit data memory RAM

– 14-bit adress bus and 24-bit data bus for

external memory expansion

• Incremental encoder interface

• Programmable digital I/O

• Integrated power-on-reset

• High performance DSP integrated with fast

12-bit ADC provides for true single chip

solution

• Fully code compatible with all ADSP-21xx

and ADMCxx family products

• Algebraic assembly language for easy pro-

gramming

• External address and data bus allows exter-

nal memory to be added as needed

• Flexible encoder interface unit for position

feedback

• Integrated power-on-

reset function and

voltage reference

remove system cost

Applications
