DSPIC33EP512GM710-H/BG - 70 MIPS 16-bit DSC, 512KB Flash | Microchip
MPN: DSPIC33EP512GM710-H/BG ✓ ActiveDSPIC33EP512GM710-H/BG Overview
A digital signal controller combines the computational power of a DSP engine with the peripheral set and ease of use of a microcontroller. Within the embedded processing hierarchy, the dsPIC33E family sits between general-purpose 16-bit MCUs and standalone DSPs, providing a single-chip solution for control-oriented digital signal processing tasks such as field-oriented motor control, digital power conversion, and sensor fusion.
Key features include the 70 MIPS dsPIC33E CPU core with integrated DSP instructions (single-cycle MAC, 40-bit accumulator), two on-chip operational amplifiers, a CAN 2.0B module, and high-resolution PWM peripherals targeted at motor control - the datasheet headline is literally '70 MIPS, Motor Control, OpAmps, CAN'. The GM710 variant offers the largest memory configuration (512 KB Flash / 48 KB RAM) in its pin class.
Architecturally, the dsPIC33E core pairs a modified Harvard 16-bit pipeline with a dedicated DSP multiply-accumulate unit, zero-overhead looping, and hardware division, while an extensive DMA controller offloads data movement between peripherals and RAM. The analog front end (op amps, 10/12-bit ADC with up to 4 Msps sampling on selected devices) enables direct sensor interfacing.
Typical applications include single and dual motor drives (the manufacturer's Single-Dual Motor Control PIM, document 50002216a, is built around this exact part), digital power supplies and solar inverters, industrial automation nodes using the CAN bus, and high-temperature sensing systems benefiting from the -40C to +150C 'H' temperature grade.
Design consideration: place the 0.1 uF decoupling capacitors on every VDD ball as close as possible to the 121-TFBGA package, and route the oscillator traces away from high-current PWM outputs to preserve the 70 MIPS core clock integrity.

Typical Applications
DSPIC33EP512GM710-H/BG is suitable for 6 applications: Single and Dual Motor Drives, Digital Power Conversion, Industrial Automation with CAN Bus, High-Temperature Sensing and Control, Embedded Signal Processing Nodes, Robotics and Servo Control.
Single and Dual Motor Drives
The DSPIC33EP512GM710-H/BG is purpose-built for motor control: its 70 MIPS DSP core executes field-oriented control (FOC) algorithms with single-cycle MAC instructions, while the high-resolution PWM modules generate complementary outputs with dead-time insertion for three-phase inverters. Microchip's own Single-Dual Motor Control PIM (document 50002216a) demonstrates driving one or two motors using the device's two internal op amps and external passive networks for current sensing. The 512 KB Flash holds both the control firmware and sensorless observer code with headroom for future field upgrades. In the 121-TFBGA package, the distributed VDD/VSS ball array also spreads switching heat across the PCB, benefiting closed-loop drive designs that run continuously near the -40C to +150C limits.
Recommended
Digital Power Conversion
Digital power supplies, LLC converters, and solar micro-inverters demand deterministic high-frequency control loops, which the 70 MIPS dsPIC33E core delivers with zero-overhead looping and hardware division. The on-chip high-speed ADC paired with the DSP engine closes current-mode loops at switching frequencies well above audibility, while the 512 KB Flash accommodates multiple converter profiles, compensation tables, and communication stacks in one image. The 48 KB RAM buffers telemetry and transient logs. The 'H' grade -40C to +150C operating range allows placement inside thermally enclosed power stages, and the CAN 2.0B module links converters into distributed power systems without external transceiver-controller logic on the digital side.
Recommended
Industrial Automation with CAN Bus
In factory automation nodes, the DSPIC33EP512GM710-H/BG combines a CAN 2.0B controller - the datasheet headline peripheral alongside motor control - with enough 70 MIPS DSP throughput to run local control loops and condition sensor signals via its two op amps before digitization. The 512 KB Flash stores protocol stacks plus application logic, and the 48 KB RAM queues CAN frames and process data without external memory. The -40C to +150C rating of the 'H' grade tolerates cabinet hot spots near drives and actuators. Because the 121-TFBGA package minimizes board area, the device fits compact I/O modules, and the same die in the 100-pin TQFP ('-I/PF') supports development boards before BGA production.
Recommended
High-Temperature Sensing and Control
Applications such as under-hood automotive auxiliaries, downhole instrumentation, and industrial process sensing benefit directly from the DSPIC33EP512GM710-H/BG's -40C to +150C operating range - far beyond the +85C ceiling of standard MCU grades. The on-chip op amps amplify low-level sensor outputs (thermocouples, pressure bridges, current shunts) locally, reducing external analog component count, while the 16-bit DSP engine performs filtering, linearization, and FFT-based diagnostics at 70 MIPS. The 512 KB Flash retains calibration tables and data-logging firmware, and the 121-TFBGA ball array provides thermal conduction into the PCB. This makes the part a single-chip sensing-plus-control solution where conventional MCUs would need derating or shielding.
Recommended
Embedded Signal Processing Nodes
As a digital signal controller, the DSPIC33EP512GM710-H/BG fills the gap between general 16-bit MCUs and standalone DSPs: its dsPIC33E core executes single-cycle multiply-accumulate, 40-bit accumulators, and bit-reversed addressing for FFTs, sustaining 70 MIPS for audio preprocessing, vibration analysis, and power-quality metering. The 512 KB Flash keeps coefficient sets and multiple algorithm branches resident, while 48 KB RAM provides working buffers for real-time block processing. Compared with an MCU-plus-DSP two-chip solution, this single 121-TFBGA device reduces BOM count, board area, and inter-chip latency. The CAN interface then streams processed results to supervisory controllers in distributed measurement networks.
Recommended
Robotics and Servo Control
Robot joint and servo controllers need coordinated multi-axis control with fast current loops - exactly the workload the DSPIC33EP512GM710-H/BG's 70 MIPS core, motor-control PWM, dual op amps, and CAN bus were designed around. Each servo axis requires FOC execution at tens of kHz; the DSP engine sustains this with cycles left for trajectory planning, encoder interpolation, and CANopen-style communication frames handled by the on-chip CAN 2.0B module. The 512 KB Flash stores kinematics and safety routines, and the -40C to +150C range suits joints near motors where ambient temperatures climb. Using the 121-TFBGA package keeps the controller PCB compact enough to mount inside the actuator housing itself.

Key Differentiators
- Highest memory in the GM710 pin class (vs DSPIC33EP256GM710-H/BG)
- -40C to +150C extended temperature rating (vs DSPIC33EP512GM710T-I/PF)
- Minimal board area via 121-ball TFBGA (vs DSPIC33EP512GM710-H/PF)
Design Notes
The 121-TFBGA requires a controlled PCB process: use a solder-mask-defined or non-solder-mask-defined land pattern exactly per the Microchip packaging datasheet, with via-in-pad filled and planarized if routing escapes beneath the array. Design the breakout with 0.2-0.3 mm trace/spacing rules and plan for X-ray inspection in production - solder joints under a BGA cannot be visually verified. Keep at least one full ground ball layer dedicated to VSS return paths for the PWM and CAN peripherals.
The 'H' grade guarantees operation to +150C junction/ambient per the device rating, but self-heating must be budgeted: at 70 MIPS with all peripherals active, core current is highest, and ambient temperature near motor drives often exceeds 85C. Estimated: leave at least 25C margin to the +150C limit by verifying worst-case current draw at maximum clock in your application firmware, and use thermal vias under the BGA array into inner copper planes to spread heat across the board rather than concentrating it under the die.
At 70 MIPS the external crystal/clock traces are sensitive to coupling from motor-control PWM outputs switching amps of current. Route the oscillator traces as short as possible, guard them with ground, and keep them on layers away from PWM nets. Place 0.1 uF decoupling capacitors at every VDD ball pair using microvias if possible. Because a TFBGA cannot be reworked in the field like a TQFP, validate the full peripheral pin multiplexing assignment in software (PPS) before PCB release.
Do not confuse the suffixes: '-H/BG' is the 121-TFBGA high-temperature part, while '-I/PF' and '-E/PT' are TQFP variants of the same die - they are not footprint-compatible and ordering the wrong suffix forces a redesign. Also, the 6-page 'PIM Information Sheet' (177 KB) indexed by datasheet aggregators is NOT the full device datasheet; download the complete family datasheet from Microchip before finalizing schematics.
