Microchip enhances dsPIC family for harsh environments


The latest addition to Microchip's dsPIC family is said to bring improved noise immunity and robustness for applications operating in harsh environments, as well as the ability to run from a 5V supply. The parts offer a capability of 70MIPS and feature DSP acceleration for high speed control algorithms. 

Called the dsPIC33EV family, the range is described as the first dsPIC digital signal controller to feature ECC flash for increased reliability and safety. Other safety critical features include Cyclic Redundancy Check, Deadman Timer, Windowed Watchdog Timer peripherals, a backup system oscillator and certified Class B software. 

Up to six motor control PWMs are available, as well as a 12bit A/D converter and operational amplifiers. The combination is said to suit motor control applications. 

Automotive touch interfaces are enhanced by the higher operating voltage, allowing more dynamic range and support for larger screens. Capable of operating at temperatures of up to 150°C, the parts are qualified to AEC-Q100 Grade 0. Peripherals include CAN (optional) and SENT for automotive communications 

The EV is available in 28, 44 and 64pin options and in SOIC, QFN, SPDIP and TQFP housings. Flash can range from 64 to 256kbyte.
