Microchip’s 5V “EV” dsPIC33 MCUs offer enhanced noise immunity, ECC flash
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 features of this family include up to six advanced motor control PWMs, 12-bit ADC, and operational amplifiers, a combination configured for motor control applications. The dsPIC33EV devices provide interface to 5V automotive sensors such as level or flow sensing, with improved noise immunity and enhanced reliability, and provide 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 including under-hood applications.
Peripheral integration features include CAN and SENT peripherals for automotive communications, 70 MIPS performance with DSP acceleration for high-speed control algorithm execution. These features, combined with the lower system cost and high performance of the dsPIC33EV family, make it well suited for a wide range of applications in the appliance (e.g., dryers, refrigerators, dishwashers, range hoods and control panels), industrial (e.g., power tools, sewing machines, actuators, building controls and HVAC systems), automotive markets (e.g., sensors, user interface, fuel pumps, cooling fans and water pumps), among others.
The dsPIC33 “EV” family is supported by Microchip’s dsPIC33EV 5V CAN-LIN Starter Kit (part # DM330018, $79.99). For motor control applications, a new dsPIC33EV256GM106 5V Motor Control Plug-In Module (part # MA330036, $25.00) is available to plug into the Low Voltage Motor Control Development Bundle (part # DV330100, $369.00).
Devices in the dsPIC33EV family are available in 28 SOIC, 28 QFN, 28 SPDIP, 44 TQFP, 44 QFN, 64 TQFP, and 64 QFN packages, with Flash memory ranging from 64 kB to 256 kB, including options with and without CAN. Prices at $1.34 in volume.
