DSPIC33EV32GM102-E/SP Overview
A digital signal controller combines the computational core of a microcontroller with DSP-class math capability in a single device. In the power-management hierarchy, a DSC sits between general-purpose MCUs and full DSP processors: it executes deterministic control loops while performing multiply-accumulate operations needed for digital power conversion, motor control and sensor signal processing. The dsPIC33EV family extends the classic dsPIC33 architecture with a 5V-tolerant supply domain, reducing the need for level shifting and external regulators in harsh 12V/24V industrial and automotive electrical environments.
Key features of this part include the 5V-rated dsPIC DSC core running at up to 60 MIPS, on-chip CAN (Controller Area Network) for automotive and industrial networking, an extended industrial-to-automotive temperature grade (-40C to +125C), and Microchip Functional Safety (FuSa) support. The 32KB Flash is self-programmable, and the 4KB RAM supports the DMA-driven data movement typical of digital power firmware.
Architecturally, the dsPIC33EV core is a modified Harvard 16-bit processor with DSP instructions, integrated peripherals, and clock/pll flexibility that lets the DSC run from a low-cost crystal while multiplying up to the maximum 60 MIPS execution rate. The integrated CAN, motor-control PWM, and analog peripherals on the GM102 family variant make it a single-chip solution for inverter and node controller designs.
Typical applications include BLDC/DC motor control in appliances and power tools, automotive body and powertrain sensor nodes on the CAN bus, and industrial digital power supplies (PFC, LLC) where 5V noise immunity is a design advantage.
A key design consideration: the DIP-28 (SPDIP) package suits prototyping and through-hole production; for space-constrained SMT designs, the same die is available in SSOP-28 as DSPIC33EV32GM102-E/SS, but it is not footprint-identical to the /SP.

Typical Applications
DSPIC33EV32GM102-E/SP is suitable for 6 applications: Automotive CAN Sensor Nodes, BLDC and DC Motor Control, Industrial Digital Power Supplies, Home Appliances, Industrial Automation and PLC I/O Modules, Prototyping and Low-Volume Embedded Systems.
Automotive CAN Sensor Nodes
The DSPIC33EV32GM102-E/SP fits automotive node designs because it is AEC-Q100 qualified with a -40C to +125C extended range and integrates an on-chip CAN peripheral in a 5V supply domain that survives noisy vehicle harness transients. In a typical body-control or sensor node, the DSC runs its main control loop at up to 60 MIPS while the CAN peripheral handles network traffic with DMA-assisted message buffers, keeping CPU overhead low. The 5V I/O directly drives optocouplers and discrete drivers without level shifting, and the 32KB Flash supports bootloader-based OTA/firmware updates over CAN. The through-hole SPDIP package also aids serviceability in low-volume vehicle aftermarket modules.
Recommended
BLDC and DC Motor Control
The dsPIC33EV family is explicitly positioned by Microchip for motor control, and the GM102's 60 MIPS DSP core executes field-oriented control or trapezoidal commutation loops with single-cycle multiply-accumulate operations. The 5V logic provides noise immunity in the electrically harsh environment near inverter power stages, and the extended -40C to +125C grade suits motor housings and power-tool bodies where ambient temperatures rise. PWM outputs drive gate drivers for the three-phase bridge while ADC inputs sense phase currents; the 4 DMA channels move ADC results without CPU intervention, tightening control-loop jitter. The family also connects directly to Microchip's motor-control development boards and PIM ecosystem.
Recommended
Industrial Digital Power Supplies
Digital PFC, LLC and buck converter controllers benefit from the DSC's DSP math plus deterministic interrupt latency at up to 60 MIPS. The 5V supply domain of the dsPIC33EV family simplifies interfacing with gate-driver logic levels common in offline power stages and improves noise margins near switching circuitry. The GM102's 32KB Flash holds a compensator, protection state machine, and PMBus/CAN communication in one chip, while the extended temperature grade tolerates power-supply internal ambient temperatures of +105C to +125C. DMA-driven ADC sampling enables fast overcurrent protection loops independent of the main firmware execution path.
Recommended
Home Appliances
Microchip targets the dsPIC33EV family at appliances operating in harsh electrical environments: compressors, fans and pumps in refrigerators, washers and air conditioners. The 5V I/O tolerates the switching noise of triac and relay loads, the AEC-Q100 qualification exceeds typical appliance reliability requirements, and the integrated CAN enables modular appliance architectures where a main board communicates with inverter and sensor boards. The 60 MIPS core runs sensorless BLDC commutation for variable-speed compressors while simultaneously servicing user-interface and safety-interlock code, all within 32KB of self-programmable Flash.
Recommended
Industrial Automation and PLC I/O Modules
The extended temperature rating, 5V noise-immune I/O and CAN bus make the GM102 a fit for PLC I/O expansion modules and factory-floor sensor converters. The DSC's DSP instructions enable on-module filtering, RMS calculation and FFT-based diagnostics of current/voltage waveforms at 60 MIPS without an external DSP. The through-hole 28-pin SPDIP package simplifies design of DIN-rail modules that are hand-soldered or reworked during customization, and the 32KB Flash with self-write supports field-updatable calibration tables and firmware via the CAN or serial link.
Recommended
Prototyping and Low-Volume Embedded Systems
The 28-pin SPDIP through-hole package is ideal for breadboards, socketed prototypes and low-volume products where automated SMT assembly is not economical. The same die is available in SSOP (DSPIC33EV32GM102-E/SS), so firmware written on the /SP prototype transfers unchanged to a production SMT layout. With Microchip's low-cost programmers and the free MPLAB X / XC16 toolchain, the total entry cost for dsPIC33EV development is minimal, while AEC-Q100 qualification gives the finished prototype a path to production in demanding environments.

Key Differentiators
- Extended -40C to +125C AEC-Q100 grade in through-hole DIP (vs DSPIC33EV32GM102-I/SP)
- Twice the program memory headroom on the same footprint (vs DSPIC33EV32GM004-E/P8)
- 5V supply domain eliminates level shifting (vs 3.3V-only 16-bit DSP/MCU competitors)
Design Notes
Design the 5V rail with local 0.1uF ceramic decoupling at each VDD pin (pins 8 and 14) plus bulk 10uF near the DIP socket. The dsPIC33EV core regulator requires the specified VCAP capacitor on pin 7 - value and type must follow the family datasheet DS70005144H; omitting it causes brown-out resets. The separate AVDD/AVSS pins (27/28) should get an RC filter from the digital 5V rail to keep ADC noise low in motor-control and power-supply sensing applications.
The DIP-28 lead frame has higher ground-path inductance than SMT packages, so use a solid ground plane on the PCB even for through-hole layouts. Route the MCLR line (pin 1) with a pull-up resistor and keep it short; it doubles as the ICSP programming connection (with PGC pin 13 and PGD pin 12), so provide a programming header footprint. Series-resonant crystal layout for OSC1/OSC2 (pins 10/11) should keep crystal and load capacitors within a few millimeters of the pins.
Three frequent mistakes with this part: (1) assuming the /SP and /SS variants are interchangeable - they share the die but not the footprint, so BOM substitution requires layout approval; (2) selecting the -I/SP industrial grade for designs that see +105C ambient near motor drives - the -E/SP extended grade is required above +85C; (3) forgetting that peripheral pins are multiplexed - configure Peripheral Pin Select registers in firmware before relying on PWM/CAN/UART pin mappings. Always verify exact DC/AC limits against family datasheet DS70005144H.
