Microchip’s new 5V DSCs boast enhanced noise immunity in harsh environments

Microchip has launched a new family of 16-bit dsPIC33 Digital Signal Controllers (DSC). The dsPIC33 EV family provides 5V operation for improved noise immunity and robustness, and is targeted 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 dsPIC33EV devices also include 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 six advanced motor control PWMs, 12-bit ADC, and operational amplifiers, an ideal combination for motor control applications. The dsPIC33EV devices provide easy interface to 5V automotive sensors such as level or flow sensing, with improved noise immunity and enhanced reliability, and provide plenty of performance to execute smart sensor filter algorithms and integrate CAN communication software.

For robust automotive touch user interfaces, the 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 that are ideal for under-hood applications. The advanced peripheral integration features include CAN and SENT peripherals for automotive communications, 70 MIPS performance with DSP acceleration for high-speed control algorithm execution.
