Motor control range boosted
1 min read
Microchip has expanded its dsPIC family of digital signal controllers with the launch of the dsPIC33EP512GM710. The move is said to add higher levels of integration for motor control applications.
According to the company, the latest DSCs enable dual motor control, featuring 12 motor control pwm channels (six pairs), dual 12bit a/d converters, multiple 32bit quadrature encoder interfaces and two CAN modules.
With this level of integration and a processing power of up to 70MIPS, it suggests devices in the family can control two motors independently. The devices can also act as a communication hub, connecting multiple CAN buses in automotive and industrial applications.
Alongside up to 512kbyte of flash and up to 48kbyte of ram, the devices integrate four op amps and two independent a/d converter modules, configurable as 10bit 1.1Msample/s with four sample and holds, or 12bit, 500ksample/s with one sample and hold, supporting up to 49 channels. The family also includes a peripheral trigger generator for scheduling complex, high speed peripheral operations.
Options for the devices, which are now in volume production, include 44, 64, 100 and 121 pin tqfp, qfn and tfbga packages.
