DSPIC33EP64GS708-E/PT - 16-bit 70 MIPS Digital Power DSC | Microchip

The Microchip Technology DSPIC33EP64GS708-E/PT is a 16-bit digital signal controller (DSC) from the dsPIC33EP GS family for digital power applications, delivering up to 70 MIPS core performance with 64KB (64K x 8) of Flash memory and 8KB of RAM, housed in an 80-pin TQFP (12x12 mm) package with extended automotive temperature range (E-grade, -40C to +125C). A digital signal controller combines the computational throughput of a DSP with the deterministic control and peripheral set of a microcontroller. Within the power-management hierarchy, the dsPIC33EP GS series targets digital switch-mode power supplies (SMPS) and power-conversion systems, sitting above general-purpose MCUs in control-loop capability while remaining programmable in C like any PIC/dsPIC device. Key features include an interconnected high-speed PWM module purpose-built for multi-phase and multi-loop power conversion, high-speed ADC with an integrated programmable gain amplifier (PGA), and on-chip comparators that close fast protection loops without CPU intervention. Dual-partition Flash supports live field firmware updates, important for grid-tied and server power products that cannot tolerate downtime. The GS-series peripheral interconnect allows ADC sample events to trigger PWM updates within a single control period at converter switching frequencies of hundreds of kilohertz. Architecturally, the dsPIC DSC core provides DSP-class multiply-accumulate (MAC) instructions and dual operand fetch, so Proportional-Integral (PI) and 3p3z compensator loops execute efficiently at 70 MIPS, leaving headroom for housekeeping tasks such as communication and housekeeping sequencing. Typical applications include AC-DC converters and interleaved power factor correction (PFC), DC-DC converters and LLC resonant stages, solar micro-inverters, and automotive AEC-Q100 qualified power modules. When designing with this device, budget ADC sampling and PWM dead time carefully at high switching frequency, and use the on-chip comparators for cycle-by-cycle current limiting rather than software-only protection.

A digital signal controller combines the computational strengths of a microcontroller (MCU) with the math-acceleration of a digital signal processor (DSP) in a single core. In the power-management hierarchy, the dsPIC33EP GS family sits at the system-control level, orchestrating switch-mode power conversion loops, power factor correction stages, and inverter control while also handling housekeeping tasks such as communication, sequencing, and fault management. Key features of this device include its 70 MIPS 16-bit pipeline core, dual-partition FLASH supporting live field updates, and a peripheral set purpose-built for digital power: interconnected high-speed PWM modules, high-speed ADC with hardware support for multiple simultaneous sampling, integrated programmable gain amplifiers (PGA), and analog comparators tightly coupled to the PWM for cycle-by-cycle current limiting. The architecture ties the ADC, comparators, and PWM into a deterministic control loop with minimal CPU intervention, which is what distinguishes the GS series from general-purpose dsPIC33EP GP variants. Functional Safety (FuSa) support documentation makes it suitable for safety-relevant industrial power designs. The dual-partition FLASH allows firmware execution from one partition while the other is erased and reprogrammed, enabling fail-safe over-the-air or in-field updates. Typical applications include AC-DC converters, power factor correction (PFC) stages, digital lighting ballasts, solar micro-inverters, battery chargers, and uninterruptible power supplies (UPS). The 350W interleaved PFC reference design from Microchip demonstrates the family's intended use in universal-input single-output power conversion. When designing with this DSC, plan control-loop timing around the 70 MIPS core budget and route high-frequency PWM outputs away from analog PGA/ADC inputs; the 0.5 mm terminal pitch TQFP requires careful PCB land-pattern design. Verify that the industrial temperature grade (-40C to +85C for the /I suffix) matches your thermal environment, selecting the /E grade (up to +125C) for harsher conditions.

A digital signal controller combines the computational throughput of a digital signal processor with the deterministic control architecture and peripheral set of a microcontroller. Within the power-management hierarchy of embedded systems, the DSC sits above general-purpose MCUs and below dedicated DSPs, making it the preferred choice for closed-loop switch-mode power supplies, digital lighting, and motor control where fast interrupt response and hardware PWM resolution matter. Key features include the dsPIC33EP GS core running at 70 MIPS from a 3.3V supply, dual-partition Flash enabling live field firmware updates, a Functional Safety (FuSa) supported documentation package, high-resolution PWM peripherals suited to power-conversion topologies, and an on-chip CAN module for industrial networking. Per the Microchip product page, the device status is In Production. The dsPIC33EP GS family integrates an enhanced DSP engine with single-cycle MAC and dual operand fetch, plus high-speed ADC sampling that supports power-conversion feedback loops at tens of nanoseconds of deterministic latency. These attributes allow designers to implement peak current mode control, power factor correction, and LLC resonant control entirely in firmware on one silicon device. Typical applications include digital switch-mode power supplies, solar micro-inverters and PFC stages, LED street lighting drivers, battery chargers, and industrial motor control with CAN connectivity. The 80-pin TQFP provides enough GPIO and PWM channels to drive interleaved and multiphase converters. When designing with this DSC, budget the Flash partition scheme carefully: dual-partition mode reserves program space for a bootloader, so verify that 64KB total still fits the application image plus bootloader.
