DSPIC33EP128GM310-H/PT - 70 MIPS 16-bit DSC 128KB TQFP-100 | Microchip

The Microchip Technology DSPIC33EP128GM310-H/PT is a 16-bit dsPIC33E digital signal controller (DSC) delivering up to 70 MIPS performance with 128 KB (43K x 24) of Flash program memory, operating at 3.3V in a 100-pin TQFP (12x12 mm) surface-mount package. The -H suffix denotes an extended-temperature automotive-grade variant qualified to AEC-Q100, supplied in tray packaging. A digital signal controller combines the compute architecture of a microcontroller with the mathematical throughput of a digital signal processor. Within the power-management hierarchy of embedded systems, a DSC sits between general-purpose MCUs and dedicated DSPs: it executes control-loop code and DSP-style MAC (multiply-accumulate) instructions on a single 16-bit Harvard architecture core, which is why DSCs dominate digital motor control and power conversion designs. Key features include the 70 MIPS dsPIC DSC core with integrated DSP engine, single-cycle MAC and dual fetch; enhanced on-chip peripherals including analog comparators and operational amplifiers for motor feedback conditioning; flexible Peripheral Pin Select (PPS) for remapping digital I/O; and multiple PGECx/PGEDx pin pairs supporting in-circuit serial programming (ICSP) via MPLAB tools such as SNAP, ICD and REAL ICE. The dsPIC33EP128GM3xx architecture provides a broad peripheral set aimed at control systems: PWM modules suited to three-phase inverter drives, high-speed ADCs for current sensing, UART/SPI/I2C communication, and a DMA controller that offloads data movement from the CPU. The 128 KB Flash supports compiled control algorithms plus bootloader headroom, and 3.3V operation aligns with modern logic rails. Typical applications are precision motor control (BLDC, PMSM, stepper drives), digital power supplies and solar inverters, industrial automation nodes, and sensor signal processing where DSP instructions accelerate filtering. Design consideration: connect every VDD/VSS pair per the datasheet, and pair ICSPCLK/ICSPDAT from the same PGECx/PGEDx pair when wiring the programming header.

A digital signal controller combines the computational architecture of a digital signal processor - single-cycle MAC, barrel shifter, dual operand fetch, and DSP instruction set - with the deterministic control peripherals of a microcontroller. Within the power-management hierarchy, the dsPIC33E family sits above basic MCUs and below standalone DSPs, making it the de-facto choice for closed-loop motor control, digital power conversion, and sensing applications that need both math throughput and rich peripherals on one chip. Key features of this GM3-series device include 12 motor-control PWM channels (MCPWM), 8 input capture and 8 output capture/compare channels, 2 quadrature encoder interfaces (QEI) for servo feedback, 4 integrated operational amplifiers for current-sense signal conditioning, a Charge Time Measurement Unit (CTMU) for capacitive-touch and precision timing, and the Peripheral Trigger Generator (PTG) for hardware-automated sequences that offload the CPU. Technically, the dsPIC33EP core executes from Flash with pipelined 16-bit Harvard architecture, includes 4 DMA channels for peripheral-to-RAM transfers without CPU intervention, and supports Peripheral Pin Select (PPS) so most digital peripherals can be routed to any of the remappable RPn pins - a major advantage for PCB layout flexibility and board respins. Operating voltage is 3.3V, and the I-grade temperature range covers -40C to +85C for industrial environments. Typical applications include brushless DC and PMSM motor drives (using MCPWM, QEI, and the on-chip op-amps for shunt-current amplification), digital SMPS and power-factor-correction converters, and industrial sensor front ends where the CTMU and 12-bit ADC acquisition pipeline reduce external component count. Design consideration: because the DSC runs at up to 70 MIPS from an internal PLL, apply rigorous power-supply decoupling on all VDD/VSS pairs and follow the Microchip clock-routing guidelines in the family data sheet to keep switching noise out of the analog op-amp front ends.

The E/SP suffix denotes the extended automotive temperature grade in the SPDIP package. Architecturally, the dsPIC33EP core supports C compiler development in Microchip MPLAB X with the XC16 compiler, and in-circuit serial programming (ICSP) through any PGECx/PGEDx pin pair, simplifying field updates and debugging. The DMA controller offloads data movement between peripherals and RAM, freeing CPU cycles for control algorithms. Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power supplies and converters, automotive auxiliary systems requiring AEC-Q100 parts, and general-purpose embedded control with DSP filtering requirements. Design consideration: the SPDIP package suits prototyping and low-volume through-hole assembly; for space-constrained or automated SMT production, the same die is available in SSOP and QFN-suffix packages, but those are not drop-in replacements for the SPDIP footprint.
