DSPIC33EP64GS805T-I/PT - 70 MIPS 16-bit DSC 48-TQFP | Microchip

The Microchip Technology DSPIC33EP64GS805T-I/PT is a 16-bit digital signal controller (DSC) delivering 70 MIPS from a dsPIC33EP core with 64KB of Flash program memory and 8KB of RAM, housed in a 48-pin TQFP (7x7 mm) surface-mount package and operating from a 3.0V to 3.6V supply over -40C to +85C. A digital signal controller combines the computational throughput of a DSP with the peripheral integration and control architecture of a microcontroller. Within the power-management hierarchy, the DSC sits above generic MCUs: it closes high-bandwidth control loops digitally, replacing analog compensation networks in switch-mode power supplies. The dsPIC33EP family executes DSP instructions (MAC, dual fetch) alongside standard MCU code, making it a bridge between real-time signal processing and embedded system control. The GS80x family is purpose-built for digital power conversion. Its interconnected high-speed PWM module provides complementary outputs with dead-time control, fault inputs, and phase-shifted or interleaved topologies support. A high-speed 10/12-bit ADC with up to 4 MSPS capability feeds on-chip analog comparators and a programmable gain amplifier (PGA), enabling current-mode control without external signal-conditioning stages. The device integrates a CAN 2.0B controller, up to two I2C and two SPI ports, UART channels with I2S support, 4-channel DMA, 7 timers, and 33 general-purpose I/O. Dual-partition Flash supports live firmware updates, critical for field-deployed power converters. Peripherals communicate through an internal bus architecture that reduces latency in time-critical control loops executing at 70 MIPS. Typical applications include AC-DC converters, interleaved power factor correction (as demonstrated in Microchip's 350W Interleaved PFC reference design), multi-output buck/boost regulators, digital lighting ballasts, battery chargers, and solar micro-inverters. When designing with this DSC, budget the 3.0V to 3.6V supply carefully; the high-speed PWM and ADC require clean decoupling on every VDD/VDDCORE pin pair. The Tape & Reel (T suffix) packaging suits automated pick-and-place production.

A digital signal controller combines the computational throughput of a digital signal processor (DSP) with the peripheral integration and control-oriented architecture of a microcontroller (MCU). Within the power-management hierarchy, a DSC sits between a general-purpose MCU and a dedicated power-control ASIC: it executes high-frequency closed-loop control algorithms - such as voltage-mode, current-mode, or multi-loop digital control - in software while providing purpose-built peripherals for sensing and switching. The dsPIC33EP GS family from Microchip is specifically engineered for digital switch-mode power conversion. The defining feature set of the GS variant targets SMPS and digital power conversion: interconnected high-speed PWM peripherals for multi-phase and complementary switching, an ADC combined with programmable gain amplifiers (PGA) and comparators for fast current-loop feedback, and a CAN interface for system communication. The 70 MIPS core allows execution of multi-loop compensation at switching frequencies well into the hundreds of kilohertz. Architecturally, the device uses a modified Harvard 16-bit core with DSP instruction extensions (MAC, dual operand fetch), hardware division support, and deterministic interrupt latency, which are essential for time-critical control loops. The interconnected PWM, ADC, and comparator blocks can trigger each other without CPU intervention, offloading latency from firmware. Typical applications include AC-DC power supplies, interleaved power factor correction (PFC), DC-DC converters, solar micro-inverters, battery chargers, and lighting ballasts. Microchip's Interleaved PFC reference design, producing up to 350W from universal AC input, demonstrates the family's intended use. Design consideration: verify PGECx/PGEDx pairs are used as matched pairs for ICSP in-circuit serial programming and debugging, and budget the ADC/PWM interconnect configuration carefully when implementing multi-loop control.

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.

DSPIC33EP64MC204-I/TL - 70MIPS 64KB DSC | Microchip | Motor Control

The Microchip Technology DSPIC33EP64MC204-I/TL is a 16-bit dsPIC33EP digital signal controller (DSC) delivering up to 70 MIPS from 64KB (22K x 24) of Flash program memory, housed in a 44-pin VTLA (6x6 mm) exposed-pad QFN package operating from 3.0V to 3.6V across -40C to +85C. A digital signal controller combines the compute architecture of a microcontroller with the math acceleration of a digital signal processor. In the power-management hierarchy, the dsPIC33EP family sits above basic 16-bit MCUs and below dedicated DSPs, offering a single-chip solution that runs control loops, handles communications, and drives power electronics simultaneously. This makes DSCs the de facto standard for digital power conversion and precision motor control. Key features include the 70 MIPS dsPIC DSC core with integrated DSP engine, 64KB Flash sized as 22K x 24 instruction words, and connectivity peripherals including I2C, SPI, UART/USART, IrDA, LINbus, and QEI. The MC variant specifically targets motor control with high-speed PWM outputs and advanced analog peripherals. Architecturally, the device uses a 16-bit RISC pipeline with DSP instructions (MAC, MPY) and dual operand fetch, enabling single-cycle multiply-accumulate operations that sustain high-frequency current loops in field-oriented control (FOC) schemes. The 3.3V supply domain simplifies integration with modern gate drivers and level shifters. Typical applications include brushless DC and PMSM motor drives, digital power supplies (LLC, totem-pole PFC), and industrial automation nodes requiring deterministic control-loop execution alongside serial communications. For design, budget the Flash carefully - 64KB (22K x 24 words) is ample for FOC firmware but leaves limited headroom for protocol stacks; consider the pin-compatible DSPIC33EP128MC204-I/TL if code size grows. The exposed pad must be soldered to a ground pour for thermal and signal integrity.
