16-bit DSCs for harsh environments

4 February 2015 DSP, Micros & Memory

The new dsPIC33 ‘EV’ family of 16-bit digital signal controllers (DSC) from Microchip provides 5 V operation for improved noise immunity and robustness, ideal for devices operating in harsh environments such as appliance and automotive applications.

The dsPIC33EV family is the first dsPIC DSC with error correcting code (ECC) Flash for increased reliability and safety. For safety-critical applications, the devices also include cyclic redundancy check (CRC), deadman timer (DMT) and windowed watchdog timer (WWDT) peripherals, as well as a backup system oscillator and certified Class B software.

Other key features of this family include up to 6 advanced motor control PWMs, 12-bit ADC and operational amplifiers, an ideal combination for motor control applications. The chips provide easy interfacing to 5 V automotive sensors such as level or flow sensing, and provide plenty of performance to execute smart sensor filter algorithms and integrate CAN communication software.

For robust automotive touch user interfaces, their higher-voltage operation enables more dynamic range and support for larger screen sizes. The dsPIC33EV devices offer up to 150°C operation with AEC-Q100 Grade 0 qualification enabling robust automotive applications such as under-hood systems.

Integrated features include CAN and SENT peripherals for automotive communications, and 70 MIPS performance with DSP acceleration for high-speed control algorithm execution. These features also make the dsPIC33EV range well suited for the appliance market and industrial products.
