Chandler, Ariz. — Microchip Technology Inc. has announced a new family of 16-bit dsPIC33 digital signal controllers (DSCs). The dsPIC33 "EV" family provides 5-V operation for improved noise immunity and robustness, which is suited for devices operating in harsh environments such as automotive (including sensors, user interface, fuel pumps, cooling fans and water pumps), appliance (including dryers, refrigerators, dishwashers, range hoods and control panels) and industrial (including power tools, sewing machines, actuators, building controls and HVAC systems) applications.
The dsPIC33EV family is the first dsPIC DSC with Error Correcting Code (ECC) Flash for increased reliability and safety, said Microchip. 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 include up to six advanced motor control PWMs, a 12-bit ADC, and operational amplifiers, making the devices suitable for motor control applications. The dsPIC33EV devices also provide an easy interface to 5-V automotive sensors such as level or flow sensing, with improved noise immunity and enhanced reliability. They also can 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, said Microchip. With operation up to 150°C and AEC-Q100 Grade 0 qualification, the devices can be used in under-the-hood applications. The advanced peripheral integration features include CAN and SENT peripherals for automotive communications, and 70 MIPS performance with DSP acceleration for high-speed control algorithm execution.
Availability: 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 64KB to 256KB, including options with and without CAN. The dsPIC33EV256GM106, dsPIC33EV128GM106, dsPIC33EV64GM106, dsPIC33EV256GM006, dsPIC33EV128GM006, and dsPIC33EV64GM006 are offered in 64-pin TQFP and QFN packages. The dsPIC33EV256GM104, dsPIC33EV128GM104, dsPIC33EV64GM104, dsPIC33EV256GM004, dsPIC33EV128GM004, and dsPIC33EV64GM004 are offered in 44-pin TQFP and QFN packages. The dsPIC33EV256GM102, dsPIC33EV128GM102, dsPIC33EV64GM102, dsPIC33EV256GM002, dsPIC33EV128GM002 and dsPIC33EV64GM002 are offered in 28-pin SOIC, QFN and SDIP packages. All of these new devices are available for sampling and volume production.
