AD extends precision analog µC family with application specific MCUs
Analog Devices, Inc. has extended its portfolio of precision analog microcontrollers with a device that combines new levels of on-chip integration, performance and analog peripherals required for motor control and smart sensing applications that are widely used in industrial and automotive system designs. The ADuC7128 features a powerful 32-bit ARM7 RISC microcontroller core, a 12-bit multichannel, analog-to-digital converter (ADC) operating at speeds to 1 MSPS (mega-samples-per-second) and 50 percent more embedded flash memory at 126 Kbytes.
New ADuC7128 MCU optimized for motor control and smart sensing applications, features unmatched 32-bit ARM7 RISC performance, high-speed, multi-channel data conversion and larger flash memory.
The new device builds on the success of Analog Devices’ ADuC702x precision analog microcontroller family by embedding application-specific analog peripherals that reduce development time and cost associated with existing discrete solutions in motor control and smart sensing applications.
The peripherals include 6-channel pulse-width modulation (PWM) with H-bridge mode, an on-chip quadrature encoder that deliver the speed, position and direction control required by dc motor controls, and an integrated direct digital synthesizer (DDS) and low-pass filter that generates a raw sine wave at up to 1 MHz to act as a stimulus for smart sensing applications.
