Key features include dual dsPIC DSC cores running at up to 100 MIPS each (200 MHz), dedicated peripherals assigned independently to each core for true parallel execution, high-resolution PWM (250 ps) ideal for digital power conversion, and integrated CAN FD for high-throughput automotive/industrial communication. The architecture also includes a 12-bit ADC with up to 3.5 MSPS, multiple SPI/I2C/UART interfaces, and Functional Safety (FuSa) features tailored for ISO 26262-capable systems. The dsPIC33CH512MP206-E/PT targets applications where software partitioning between cores improves system safety and responsiveness, such as field-oriented motor control, digital switch-mode power supplies, and functional-safety-critical industrial drives. Typical applications include high-performance BLDC/PMSM motor control (appliance, EV traction auxiliary, industrial servo), digital power conversion (totem-pole PFC, LLC, full-bridge converters), and automotive sensor fusion with safety isolation between control and housekeeping tasks.

DSPIC33CH512MP206-I/MR

DSPIC33CH512MP206-I/MR - 100MHz Dual-Core 16-bit DSC, 512KB Flash | Microchip

The Microchip dsPIC33CH512MP206-I/MR is a dual-core 16-bit Digital Signal Controller (DSC) operating at up to 100 MHz (200 MIPS primary, 180 MIPS secondary) in a 64-pin QFN (9x9 mm) package with exposed pad. It integrates 512 KB of Flash program memory, 64 KB RAM, and dedicated high-performance peripherals designed for precision closed-loop control. What is a DSC? A Digital Signal Controller (DSC) is a hybrid MCU-DSP architecture that combines a microcontroller's deterministic control peripherals (timers, PWMs, ADCs, digital I/O) with a Digital Signal Processor (DSP) core for high-throughput math. The dsPIC33CH family extends this with a heterogeneous dual-core topology: a master core handles control and communications while a slave core offloads time-critical DSP tasks, mirroring a hypernym hierarchy of DSC -> MCU -> microcontroller -> embedded processor -> semiconductor. Key features of this device include dual independent dsPIC33 cores, high-resolution PWM (250 ps), twelve 16-bit ADCs with up to 3.5 MSps, four 12-bit DACs, four analog comparators with 32 ns propagation delay, CAN FD, three SPI/I2S, four UART, and a parallel master port (PMP). The on-chip op-amps and 5-bit DAC references are tuned for field-oriented control (FOC) loops in motor drives. Architecturally, the device separates the cores onto independent buses with shared memory mailbox for inter-core messaging. This deterministic inter-core communication eliminates the timing jitter of a software RTOS, while each core retains its own DSP engine, register set, and interrupt controller - critical for safety-certified motor control and digital power topologies. Typical applications include high-performance motor control (FOC / PFC), digital switch-mode power supplies (SMPS), wireless battery chargers, renewable energy inverters, and functional-safety (FuSa) industrial systems. The dual-core configuration also enables sensor-fusion and advanced lighting (DALI / DMX) systems where a slave core can run autonomous DSP while the master handles communication. Designers should note that the slave core adds latency on mailbox calls; distribute workload such that the master makes decisions and the slave executes deterministic inner loops. The QFN-9x9 footprint with EP requires thermal vias under the exposed pad - up to 2.7 W dissipation at 85 C is supported with proper PCB copper. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet - a faster reading path for selection, sourcing, and PCB layout decisions on the dsPIC33CH dual-core family.

The Microchip Technology DSPIC33CH512MP206-I/PT is a 16-bit dual-core digital signal controller (DSC) that pairs a 100 MIPS main core with a 100 MIPS slave core on a single die, delivering up to 200 MIPS of aggregated DSP throughput. Housed in a 64-pin TQFP (10x10 mm) package, it integrates 512 KB of Flash program memory, 64 KB of SRAM, and high-resolution PWM peripherals targeted at precision motor control and digital power conversion. The two cores communicate through a dedicated mail-box / SFR inter-core link, enabling deterministic partitioning of control loops across the master and slave cores. A digital signal controller (DSC) is a hybrid MCU/DSP that combines the deterministic interrupt handling and peripheral set of a microcontroller with the single-cycle MAC and DSP engine of a digital signal processor. Within the broader hierarchy, the DSPIC33CH family sits above general-purpose 16-bit PIC MCUs and below 32-bit Cortex-M4F parts, targeting real-time control loops where cycle-accurate math and tight PWM timing are mandatory. Key differentiating specifications include: 100 MIPS per core at 3.0-3.6V operation, integrated high-resolution PWM with 250 ps edge placement, dual 12-bit ADC modules at 3.5 Msps each, CAN-FD, and 4 op-amps plus 4 comparators on-chip. The dual-core topology lets designers run a high-frequency current-control loop on the slave while the master handles communication stacks and state machines, reducing interrupt latency on the critical path. Typical applications span field-oriented control (FOC) of PMSM/BLDC motors, on-board EV chargers, photovoltaic micro-inverters, welding power supplies, and functional-safety industrial drives that benefit from the second core for diagnostic redundancy. The integrated op-amps simplify current-sense signal conditioning directly at the DSC pins. When designing with the DSPIC33CH512MP206-I/PT, allocate the time-critical loop to the slave core and reserve the master for housekeeping, leaving headroom for CAN-FD and EtherCAT-style communication stacks. Decouple AVDD and DVDD separately and use the on-chip op-amps for current sensing to minimize external analog components.

DSPIC33CH512MP208-E/PT

DSPIC33CH512MP208-E/PT - Dual-Core 100MHz DSC, 512KB Flash | Microchip

The Microchip DSPIC33CH512MP208-E/PT is a dual-core 16-bit Digital Signal Controller (DSC) delivering up to 100 MIPS on the master core and 90 MIPS on the slave core, packaged in an 80-pin TQFP (PT) with 0.50 mm pitch and a 12x12 mm body. It integrates 584 KB of Flash program memory (512 KB Instruction + 72 KB data Flash), 64 KB RAM, and high-resolution PWM with CAN Flexible Data-Rate (CAN FD) peripherals targeting precision motor control and digital power conversion. A Digital Signal Controller is a hybrid device that combines a microcontroller's deterministic interrupt-driven control with a Digital Signal Processor (DSP)'s single-cycle MAC engine. The dsPIC33CH family extends this further by placing two independent dsPIC cores on-chip: the master core manages application code, communication stacks, and the housekeeping peripheral set, while the slave core executes time-critical DSP loops such as field-oriented control (FOC) or power-conversion compensators, communicating with the master through deterministic dual-port RAM and shared mailbox FIFOs. This topology belongs to the broader hierarchy: DSC -> microcontroller -> embedded processor -> semiconductor IC. Key features include dual-core 16-bit architecture, 200 MHz master PLL clock with 180 MHz slave PLL, 16 high-resolution PWM channels with 250 ps resolution, four operational amplifiers and three 12-bit ADCs with up to 40 Msps combined throughput, plus CAN FD and high-speed comparators. Functional-safety features include a windowed watchdog, RAM built-in self-test (MBIST), and a dedicated slave core that can supervise the master, supporting IEC 60730 Class B and helping designers targeting ASIL-B / SIL-1 systems. Architecturally the device uses a Harvard bus with separate program and data paths, dual-issue DSP instructions, and a hardware divider to sustain real-time control loops. The high-resolution PWM (HRPWM) edge placement is generated by a micro-edge delay line, allowing switching frequencies in the multi-MHz range without losing duty-cycle precision - critical for totem-pole PFC, LLC converters, and high-FPM field-oriented motor drives. Typical applications include field-oriented motor control for industrial servo and traction drives, on-board EV charger and totem-pole PFC power supplies, solar inverters with MPPT, audio Class-D amplification, and functional-safety sub-systems. The dual-core split also suits dual-motor drone ESCs and precision robotics where one core drives the kinematics and the second core runs the per-axis current loop. When designing with this part, allocate the slave core exclusively to the deterministic control loop and let the master handle communication, sequencing, and housekeeping. Keep HRPWM analog ground returns short, decouple VDD/VSS close to the package with 100 nF + 1 µF pairs, and follow Microchip AN2721 and TB3138 for slave-core bring-up. This page synthesises distributor pricing, drop-in same-package alternatives, and practical dual-core design notes that go beyond the manufacturer datasheet itself.

DSPIC33CH512MP208-I/PT

DSPIC33CH512MP208-I/PT - 100MHz Dual-Core DSC | Microchip

The Microchip DSPIC33CH512MP208-I/PT is a 16-bit dual-core Digital Signal Controller (DSC) operating at up to 100 MHz, housed in an 80-pin TQFP (PT) package. The device integrates a 90 MIPS master core and a 100 MIPS slave core, both dsPIC33 architecture, with 512 KB Flash program memory, 64 KB RAM, and 8 DMA channels for high-throughput control loops. What is a dual-core DSC? A Digital Signal Controller combines a microcontroller's deterministic control peripherals with a DSP's mathematical throughput on a single die. The dsPIC33CH family extends this concept by partitioning the workload: the master core runs the application, communication stacks, and supervisory tasks, while the slave core executes deterministic real-time loops (motor commutation, power conversion) with its own dedicated peripheral set. Compared with single-core DSCs, dual-core devices reduce interrupt latency, decouple firmware certification boundaries, and enable parallel development of safety-critical and application code. Key features include high-resolution 250 ps PWM with 8 independent outputs, CAN FD, three UART/SPI/I2C pairs per core, and 16 timers. The dual-core architecture supports Functional Safety (FuSa) partitioning where the slave core runs safety functions independently of the main application, and on-chip interconnect enables shared memory for inter-core messaging. Integrated op-amps, comparators, and 12-bit ADC with 40 Msps capability make it suited to high-bandwidth feedback systems. The device is fabricated on a CMOS process, supports operating temperatures from -40 C to +85 C (industrial grade -I), and is housed in a 12x12 mm TQFP-80 package with 0.50 mm pitch. Programming is supported through MPLAB X IDE, MPLAB XC-DSC compiler, and the dsPIC33CH Curiosity development board, with on-chip trace and dual trace/ICE debug paths. Typical applications include field-oriented control (FOC) of PMSM and BLDC motors, digital power conversion (PFC + LLC), advanced LED lighting with adaptive dimming, and industrial drives requiring functional safety. The slave core is well suited to running the safety routine independently while the master core handles the user interface. Designers should pay close attention to pin assignment when using both cores' peripherals, since most signals are multiplexed. Use the Microchip Motor Control Application Framework (MCAF) as a starting point to avoid race conditions in inter-core messaging via the MSI (Master-Slave Interface) shared RAM.

DSPIC33CH512MP208T-I/PT

DSPIC33CH512MP208T-I/PT - 180MHz Dual-Core DSC | 512KB Flash | Microchip

The Microchip DSPIC33CH512MP208T-I/PT is a dual-core 16-bit dsPIC33CH Digital Signal Controller (DSC) combining a 180 MHz main core and a 200 MHz slave core with 584 kB of Flash and PRAM in an 80-pin TQFP (12x12 mm) package. It targets functional-safety (FuSa) and high-performance motor-control, digital-power, and real-time control applications where deterministic dual-core partitioning boosts throughput without compromising determinism. The 'T' suffix indicates tape-and-reel packaging, the 'I' industrial temperature grade spans -40 °C to +85 °C, and the 'PT' suffix specifies the 80-pin TQFP. A Digital Signal Controller (DSC) is a hybrid microcontroller that integrates a high-performance DSP engine with a general-purpose MCU core. DSCs execute single-cycle MAC instructions and dedicated DSP math paths, allowing simultaneous control-loop and signal-processing tasks. Within the broader taxonomy they sit between MCUs (microcontrollers) and full DSPs, occupying the 'real-time control' node in the power management and industrial-automation hierarchy. The dsPIC33CH family is engineered for systems where deterministic time-critical loops (FOC on field-oriented control, PFC, LLC, DCDC) must coexist with housekeeping, communication, and safety diagnostics. Key features include 584 kB of dual-partition Flash with live update, 64 kB SRAM plus 16 kB tightly-coupled PRAM for the slave core, a 12-bit ADC at 3.5 Msps, high-resolution PWM with 250 ps resolution, CAN FD, and integrated op-amps/comparators/DAC. The chip also carries the Microchip Functional Safety hardware roadmap, including lockstep CPU options and a dedicated slave core for safety monitoring and housekeeping. Architecturally, the device couples a 16-bit dsPIC DSC core and an independent slave dsPIC core on a die-interconnect bus. This dual-core structure allows designers to isolate motor-control or power-conversion code on one core while reserving the other for system management, communication, or safety tasks. The high-resolution PWM, fast ADC, and dedicated math accelerator deliver precise switching and current-sampling in tightly-looped converters. Typical applications include field-oriented control (FOC) motor drives, on-board EV chargers, totem-pole PFC power supplies, LLC and phase-shifted DCDC converters, photovoltaic micro-inverters, industrial servo drives, and functional-safety certified appliances. Each application benefits from the dual-core split: the slave core offloads housekeeping so the main core stays in tight control loops. When designing with this DSC, allocate Flash, RAM, and interrupt vectors between the two cores early in the project because the slave core has its own peripheral set and bus bandwidth. Verify board layout keeps analog and switching traces short, place decoupling directly at each VDD/VSS pair, and confirm the production-grade FOC/PFC firmware is profiled on the slave core before committing to pinout.

DSPIC33CH512MP505-E/M4

DSPIC33CH512MP505-E/M4 - 100MHz Dual-Core DSC, 512KB | Microchip

The Microchip DSPIC33CH512MP505-E/M4 is a dual-core 16-bit Digital Signal Controller (DSC) in the dsPIC33CH family, integrating a 100 MIPS Main core and a 90 MIPS Secondary core on a single die, packaged in a 48-pin UQFN (6x6 mm) with 512 KB Flash and CAN-FD peripherals. The dual-core architecture enables deterministic real-time control loops with the Secondary core handling time-critical DSP or housekeeping tasks while the Main core runs the application stack, eliminating software scheduling jitter common in single-core MCUs. A Digital Signal Controller (DSC) is a hybrid microcontroller/DSP that combines a microcontroller's deterministic interrupt handling and peripheral integration with a DSP's single-cycle MAC engine and dedicated math instructions; it sits in the product hierarchy between microcontroller (MCU) and digital signal processor (DSP), and is commonly deployed in high-performance motor control, digital power conversion, and precision sensing. The dsPIC33CH family is the dual-core evolution of Microchip's dsPIC33CK/DSC line, designed for systems that need hard real-time partitioning. Key features of the -E/M4 variant include 512 KB program Flash, 72 KB SRAM, a 200 MHz PLL-derived system clock, integrated high-resolution PWM (1 ns edge placement) with 8 output pairs, four 12-bit ADCs with 3.5 MSPS aggregate sampling, two 12-bit DACs, four analog comparators, three op-amps, two CAN-FD modules, four UART/SPI/I2C configurable serial interfaces, and a temperature range of -40C to +125C (-E industrial grade). The 48-UQFN package provides a compact footprint while exposing up to 35 general-purpose I/O and the dedicated Master/Secondary inter-core MSI mailbox for deterministic IPC. On the architectural side, the Main core boots first and can optionally launch the Secondary core from a programmable address, with shared peripherals routed via a programmable crossbar and pin ownership registers that decide which core drives each GPIO at any given moment; the two cores communicate through MSI FIFOs and shared SFRs, allowing hand-off of high-rate control loops without OS overhead. The on-chip 8-channel Event System, CTMU for capacitive touch, and dedicated crypto/hash engines further reduce external component count. Typical applications include field-oriented control (FOC) of PMSM/BLDC motors, totem-pole bridgeless PFC power-factor correction, LLC/phase-shift full-bridge digital power supplies, and functional-safety ASIL-B/ASIL-C capable drive platforms. The dsPIC33CH dual-core pattern is specifically aimed at designs that previously required an external companion DSP or FPGA. When designing with this part, pay close attention to the pin-ownership matrix early in pin allocation, because the Secondary core and Main core cannot simultaneously drive the same GPIO and conflicts must be resolved at boot-time via SFR writes. Layout the 48-UQFN with a continuous GND/PWR pour on the exposed pad for thermal dissipation - this package runs at full speed with up to 200 MHz internal clock and benefits from a 4-layer PCB.

DSPIC33CH512MP505-E/PT

DSPIC33CH512MP505-E/PT - 100MHz Dual-Core DSC | Microchip

The Microchip Technology DSPIC33CH512MP505-E/PT is a 16-bit dual-core Digital Signal Controller (DSC) combining a 100 MIPS main core and a 90 MIPS slave core, housed in a 48-pin TQFP (7x7 mm) package, with 512 KB Flash and 48 KB RAM, designed for high-performance precision motor control and digital power conversion. A Digital Signal Controller (DSC) is a hybrid device that merges a microcontroller's peripheral integration with a Digital Signal Processor's (DSP) computational throughput. Within the broader device taxonomy, a DSC sits between Microcontroller (MCU) and Digital Signal Processor (DSP); the dsPIC33CH family extends this further into a dual-core architecture where the main core offloads latency-critical tasks (PWM, ADC sampling, control loops) to the slave core. This dual-core topology is critical for latency-sensitive applications such as field-oriented motor control and LLC resonant converters, where single-core MCUs struggle to meet control-loop deadlines. Key features include integrated high-resolution PWM (1 ns duty resolution), four 12-bit, 3.5 MSPS analog-to-digital converters (ADCs) with up to 36 channels, four analog comparators with 1 ns propagation delay, four operational amplifiers, CAN-FD and I2S interfaces, and 39 general-purpose I/O pins. The 200 MHz maximum operating frequency enables single-cycle MAC operations, which are essential for real-time sinusoidal PWM generation and digital filter computation in closed-loop control. The DSPIC33CH512MP505-E/PT uses a Harvard architecture with separate program and data buses, plus a 16 KB dedicated slave-core RAM block that enables deterministic data exchange between cores without arbitration latency. Built-in hardware features such as PWM fault inputs, QEI for rotary encoders, and the Peripheral Trigger Generator (PTG) simplify firmware and reduce total component count on motor-control boards. AEC-Q100 qualification supports automotive deployment. Typical applications include sensorless field-oriented control (FOC) for three-phase BLDC/PMSM motors, digital totem-pole PFC power factor correction converters, LLC resonant converter control, on-board EV battery chargers, and industrial servo drives. The dual-core architecture allows one core to handle the PFC control loop while the second manages the DC-DC converter loop, ensuring sub-microsecond response. When designing with this device, the slave-core firmware must be loaded into the designated slave Flash region at production time, and the main core must be programmed to invoke the slave before any peripheral hand-off occurs. Decoupling requires at minimum a 0.1 µF ceramic capacitor as close as possible to every VDD/VCAP pin pair.

DSPIC33CH512MP505-I/M4

DSPIC33CH512MP505-I/M4 - Dual-Core 100MIPS DSC, 512KB Flash | Microchip

The Microchip DSPIC33CH512MP505-I/M4 is a dual-core 16-bit Digital Signal Controller (DSC) featuring a 90 MIPS master core and a 100 MIPS slave core in a 48-pin UQFN (6x6 mm) package. It integrates 512 KB of Flash program memory (584 KB total per Mouser description), 48 KB RAM, and a CAN Flexible Data-Rate (CAN FD) controller, making it designed for high-performance precision motor control and digital power conversion. Key features include dual dsPIC DSC cores with integrated DSP engine, dedicated high-resolution PWM modules optimized for field-oriented control (FOC) of motors, and separate peripheral sets assignable to either core via programmable ownership. The slave core can independently execute time-critical control loops while the master core handles communication, housekeeping, or application-layer logic, reducing interrupt latency and enabling tighter torque/speed control loops in switched-mode and PMSM drives. Typical applications include high-performance motor control (PFC + motor on a single chip), digital switch-mode power supplies, photovoltaic inverters, server/lighting ballasts, and audio Class-D amplifiers. The combination of dual-core deterministic partitioning and integrated analog (12-bit ADC, comparators, DAC) makes the device well-suited for systems that previously required two controllers plus inter-MCU communications. When designing with this device, allocate peripheral ownership early: each pin can be assigned as output by only one core at a time, though both cores can monitor it as input. Programming requires MPLAB X IDE with the dsPIC33CH plugin; the Curiosity Development Board (DM330028-2) is the official prototyping platform. Decoupling and ground-pad layout guidance from the manufacturer datasheet must be followed to achieve the rated 100 MIPS slave-core throughput.

DSPIC33CH512MP505-I/PT - 100MHz Dual-Core 16-bit DSC, 512KB Flash, 48-TQFP | Microchip

The Microchip Technology DSPIC33CH512MP505-I/PT is a 16-bit dual-core digital signal controller (DSC) in the dsPIC33CH family, delivering a 100 MHz main core and a 90 MHz secondary core with integrated DSP and enhanced on-chip peripherals. Housed in a 48-pin TQFP (7x7 mm) package, the device integrates 512 KB of Flash program memory, dedicated slave-core RAM, high-resolution PWM modules, and a CAN Flexible Data-Rate (CAN FD) controller, making it a single-chip solution for high-performance precision motor control and digital power conversion. A Digital Signal Controller (DSC) sits at the intersection of a microcontroller (MCU) and a Digital Signal Processor (DSP). The MCU side provides deterministic interrupt handling, peripherals (UART, SPI, I2C, CAN, PWM), and general-purpose I/O; the DSP side adds single-cycle MAC, saturating arithmetic, and zero-overhead looping. In the dsPIC33CH hierarchy, this places the device within: DSC -> dsPIC33 family -> dsPIC33CH sub-family (dual-core) -> motor-control and digital-power class. This dual-class positioning explains why the part is marketed for both motor-control firmware and high-frequency switching power conversion. Key features include: dual 16-bit DSC cores running up to 100 MIPS (main) and 90 MIPS (secondary), each with its own DSP engine; 512 KB on-chip Flash with live update support; up to 96 KB total RAM (including a dedicated slave-core partition); high-resolution 7.5 ns PWM with multiple fault inputs; integrated CAN FD controller; and rich analog (high-speed ADC, comparators, DAC). The dual-core architecture allows closed-loop control math on one core while the second core handles housekeeping, communication stacks, or a second motor-control loop. Typical applications span field-oriented control (FOC) of PMSM/BLDC motors, sensorless motor drives, multi-axis servo systems, on-board chargers (OBC), DC-DC converters, photovoltaic inverters, and digital LED lighting. The high-resolution PWM and fast ADC sample timing enable switching frequencies beyond 1 MHz with sub-percent duty-cycle accuracy, while the secondary core can be dedicated to housekeeping, safety monitoring, or a CAN FD communication stack. Design consideration: ensure that the main and secondary core pin-ownership tables (set in firmware) match the board's pin map before bringing the secondary core out of reset, and place decoupling capacitors (100 nF + bulk) within 5 mm of each VDD/VSS pin pair. The 48-TQFP package has limited thermal headroom - estimate the dissipation from the core clock and peripheral activity, then verify against the 31 C/W theta_JA on a 4-layer JEDEC board.

DSPIC33CH512MP505T-I/M4 - 100MHz Dual-Core DSC, 512KB Flash | Microchip

The Microchip Technology DSPIC33CH512MP505T-I/M4 is a 16-bit dual-core Digital Signal Controller (DSC) in the dsPIC33CH family, integrating a 100 MIPS main core and a 100 MIPS secondary core on a single die. Housed in a 48-pin UQFN (6x6 mm) package, it combines 512 KB of Flash program memory with 48 KB + 16 KB of RAM, dedicated PRAM for inter-core messaging, and CAN-FD connectivity. The dual-core architecture allows deterministic real-time control loops on the slave core while the master core runs communication stacks, GUI logic, or housekeeping tasks independently. A Digital Signal Controller (DSC) is a hybrid microcontroller class that fuses a deterministic 16-bit MCU pipeline with single-cycle DSP MAC and barrel-shifter hardware. The dsPIC33CH family extends the DSC concept by integrating two independently programmable cores on one silicon die, connected by a deterministic FIFO-based mailbox (MSI) interface. This topology is often compared to a microcontroller + FPGA pair but with lower latency, simpler tool flow, and shared on-chip peripherals. Compared to single-core dsPIC33CK devices, the dual-core design eliminates the need for an external companion MCU in safety-critical or hard-real-time systems. Key features include 200 MHz maximum operating frequency across both cores, 12-bit ADC with up to 3.5 MSPS, three op-amps and three DACs on-chip, configurable logic cells (CLC), and built-in functional safety features such as a windowed watchdog, deadman timer, BIST, and lock-step capable CRC. The integrated high-speed analog reduces BOM cost in motor-control and power-conversion designs by replacing external op-amps and comparators. The device supports 3.0V to 3.6V single-supply operation and is AEC-Q100 qualified for automotive environments. Typical applications include field-oriented control (FOC) of PMSM/BLDC motors, digital totem-pole PFC and LLC resonant converters, on-board chargers, and multi-axis servo drives. The slave core is typically dedicated to the inner current-control loop at sub-microsecond cycle time, while the master core handles speed/torque profile, CAN-FD communication, and fault management. When designing with this device, plan the MSI mailbox allocation between cores early - the inter-core message-passing bandwidth is finite. Use the dsPIC33CH plugins in MPLAB X IDE and MPLAB Code Configurator (MCC) to generate peripheral initialization code for both cores. Programming requires two separate hex images merged into one via MPLAB IPE.

DSPIC33CH512MP505T-I/PT - 100MHz Dual-Core DSC, 512KB Flash | Microchip

The Microchip DSPIC33CH512MP505T-I/PT is a high-performance dual-core 16-bit Digital Signal Controller (DSC) combining a 100 MIPS main dsPIC33C core and a 100 MIPS slave core, packaged in a 48-pin TQFP (7x7 mm). It integrates 512 KB of Flash program memory, 48 KB+16 KB RAM, and a rich peripheral set including CAN-FD, making it suitable for advanced real-time control applications. A Digital Signal Controller (DSC) is a hybrid class of microcontroller that combines the deterministic interrupt response and peripheral set of a traditional MCU with the high-throughput math capabilities of a DSP. In the broader taxonomy, this device sits between a microcontroller (MCU) and a digital signal processor (DSP), specialized for closed-loop control loops running at high PWM frequencies with concurrent sensor sampling. The dsPIC33CH family specifically introduces a dual-core architecture, allowing designers to partition software between a master application core and a slave core dedicated to time-critical control loops. Key differentiating specifications include the dual 16-bit dsPIC cores capable of 100 MIPS each, 512 KB of on-chip Flash split between the cores, 48 KB SRAM plus a dedicated 16 KB slave-core RAM, integrated CAN-FD peripheral, a high-resolution PWM module suited for field-oriented control (FOC) of PMSM and BLDC motors, and a wide 3.0V to 3.6V supply range with -40C to +85C industrial temperature grade. Architecturally, the dsPIC33CH uses separate program and data buses per core, deterministic interrupt latency, and tightly coupled peripherals shared across cores. The slave core can execute dedicated control tasks (such as a digital power conversion loop or motor commutation) independently of the master, offloading jitter-sensitive code and enabling deterministic cycle times without software priority inversion. Typical applications include sensorless field-oriented control (FOC) of BLDC/PMSM motors, digital switch-mode power supplies (SMPS) and totem-pole PFC stages, photovoltaic inverters, automotive body and chassis controllers, and industrial drives requiring concurrent communication and high-frequency PWM. The integrated CAN-FD also makes it attractive for vehicle and industrial networking nodes. When designing with this device, allocate the slave core to the most time-critical control loop and reserve the master for application state machines, communication stacks, and housekeeping. Ensure the decoupling network follows the manufacturer's reference layout: at minimum a 100 nF X7R ceramic per VDD pin plus a bulk 4.7 uF to 10 uF near the package.

It combines two independent dsPIC33 DSC cores (a main core and a slave core) on a single die, enabling sophisticated real-time control and DSP workloads to be partitioned for deterministic execution. The device also includes high-resolution PWM (250ps resolution), CAN-FD, and dedicated motor-control peripherals, and is qualified to AEC-Q100 for automotive applications. A Digital Signal Controller (DSC) is a hybrid microcontroller that integrates a DSP engine onto an MCU core; the dsPIC33CH family extends this with two cores on-chip. In the system hierarchy, the DSC sits between a microcontroller (MCU) and a digital signal processor (DSP), combining deterministic interrupt-driven control with hardware-accelerated math. The dual-core architecture places a fast slave core alongside the main core so time-critical tasks (current loops, commutation, housekeeping) can run independently of higher-level application code, simplifying firmware partitioning for advanced digital power conversion and field-oriented control (FOC) motor drives. Key features include dual 100 MIPS 16-bit dsPIC DSC cores, 512 KB Flash, 64 KB PRAM, 16 KB RAM, 8-channel high-resolution PWM with 250 ps edge placement, two CAN-FD modules, multiple UART/SPI/I2C interfaces, 12-bit ADC at 3.5 Msps with up to 24 channels, and a 64-pin QFN package with extended -40C to +125C operating range. Functional Safety (FuSa) features support IEC 60730 Class B and automotive safety-integrity requirements, and the AEC-Q100 qualification allows deployment in safety-critical automotive ECUs. The dual-core architecture allows the slave core to handle high-priority control loops while the main core runs communication, diagnostics, and application logic, reducing latency and jitter compared with single-core DSCs. On-chip high-resolution PWM and analog comparators support advanced topologies such as totem-pole PFC, LLC resonant converters, and multi-phase VRs, while CAN-FD and the peripheral set ease integration into vehicle body and powertrain networks. Typical applications include digital switch-mode power supplies (SMPS), totem-pole PFC and LLC converters, field-oriented control (FOC) motor drives for automotive traction and industrial servo, on-board chargers (OBC) and DC-DC converters for EVs, solar inverters, and functional-safety industrial control. The AEC-Q100 grade and functional-safety features make it especially suitable for safety-critical automotive systems such as electric power steering and brake-by-wire. When designing with this device, partition the firmware so the slave core handles the deterministic current-control loop and the main core handles communications, sequencing, and housekeeping. Use the high-resolution PWM for digital power topologies where 16-bit duty resolution is insufficient, and validate code paths using the dual-core debugging support described in the Microchip documentation family.

DSPIC33CH512MP506-I/PT - Dual-Core 200MHz DSC, 512KB Flash | Microchip

The Microchip Technology DSPIC33CH512MP506-I/PT is a dual-core 16-bit Digital Signal Controller (DSC) from the dsPIC33CH family, featuring a primary core at 180 MHz and a secondary (slave) core at 200 MHz, packaged in a 64-pin TQFP (PT, 10x10 mm). The device integrates 512 KB of Flash program memory, 64 KB RAM, and 4 KB of EEPROM, alongside CAN-FD and high-resolution PWM peripherals optimized for precision motor control and digital power conversion. A Digital Signal Controller is a hybrid architecture that combines the deterministic real-time control capability of a microcontroller with the computational throughput of a Digital Signal Processor (DSP). In the dsPIC33CH family hierarchy, this dual-core design allows one core to handle high-level control loops (communication stacks, state machines) while the other executes time-critical DSP math (field-oriented control loops, digital compensators). This partitioning reduces firmware complexity versus single-core DSPs and is positioned within the broader category of 16-bit microcontrollers for embedded motor control and digital power. Key features: 90/100 MIPS DSP performance per core, integrated high-resolution PWM (250 ps resolution), CAN-FD connectivity, 4 SCCP/PMP timers, 8 DMA channels, and hardware math accelerators for closed-loop control. Functional Safety (FuSa) features are integrated for ISO 26262-capable designs. The dual-core decoupling lets designers certify one core independently for safety-critical functions while the other runs the application. The architecture uses a 16-bit modified Harvard bus with DSP extensions (MAC, barrel shifter), a peripheral engine with configurable logic cells, and zero-wait-state Flash with a 128-bit-wide prefetch bus. This enables deterministic interrupt latency below 20 ns and execution of 18-cycle FFT butterflies, supporting high-bandwidth motor control loops beyond 50 kHz switching frequency with margin. Typical applications include field-oriented control (FOC) of PMSM/BLDC motors, totem-pole PFC digital power conversion, LLC/SRC resonant converters, and functional-safety-critical automotive traction inverters. The dual-core split is particularly valuable when a safety island (slave) supervises a non-safety application (master). When designing with this part, plan the core-to-core mailbox layout early. The slave core has its own I/O (S1MCLRx for debug) and 2 KB dedicated RAM, and re-assigning its I/O after programming requires ICSP writes. Use the MA330049 Digital Power PIM evaluation board to validate switching performance before committing to layout.

The device combines 88 KB of Flash program memory and 20 KB of RAM, supported by 8 DMA channels and multiple internal bus architectures. According to the Microchip datasheet, the dual-core topology lets one core act as a deterministic real-time controller while the other handles application logic, communication stacks, or housekeeping tasks. A Digital Signal Controller (DSC) is a hybrid device that fuses a microcontroller's deterministic control peripherals with a Digital Signal Processor (DSP)'s computation engine. In the system hierarchy, a DSC sits between a general-purpose MCU and a standalone DSP, making it ideal for closed-loop digital control, motor drive, and digital power conversion.

Key differentiating features include high-resolution PWM outputs for precision power conversion, integrated CAN Flexible Data (CAN FD) peripherals, three serial I/O interfaces, and functional-safety (FuSa) support. The slave core can be field-upgraded independently of the master core, simplifying OTA-style firmware updates. AEC-Q100 qualification is available on specific speed grades for harsh-environment designs, and the extended -40C to +125C operating temperature range suits industrial and automotive under-hood applications. Architecturally the device uses 16-bit modified Harvard cores with single-cycle MAC, dual 40-bit accumulators, and tightly-coupled DSP instructions. Eight DMA channels offload peripheral data movement, reducing CPU stalls during high-rate ADC and PWM sequencing, which is critical when the slave core drives the control loop and the master core services user interfaces. Typical applications include digital switch-mode power supplies, totem-pole PFC and LLC converters, field-oriented motor control (FOC), solar micro-inverters, on-board EV chargers, and industrial LED drivers. The dual-core partition isolates the safety-critical real-time loop on the slave core while the master runs the UI, communications, or telemetry stack. When designing with this part, pair the slave core exclusively with the high-resolution PWM, ADC, and analogue comparators used in the control loop, and avoid sharing time-critical ISR resources across cores.

Each core features independent DSP and peripheral resources, with one core designated as the master and the other as the slave for deterministic task partitioning. The device carries 88 KB of Flash program memory, dual-port RAM split into 16 KB and 4 KB regions for inter-core data exchange, and operates across a 3.0 V to 3.6 V supply range with 180 MHz master / 200 MHz slave oscillator capability. A Digital Signal Controller (DSC) is a hybrid MCU-DSP architecture that combines a microcontroller's deterministic interrupt handling with a DSP's single-cycle MAC instruction set. The dsPIC33CH family extends this concept with a heterogeneous dual-core topology where the master core runs the application framework while the slave core executes time-critical DSP or control loops in parallel. This positions the part above traditional 16-bit MCUs in the taxonomy (16-bit microcontroller -> DSC -> dsPIC33CH -> dual-core DSC) and below 32-bit Cortex-M parts in raw compute throughput, but with deterministic latency that mid-range ARM parts rarely match. Key features include a 200 MIPS slave core, dedicated high-resolution PWM with 250 ps resolution, CAN Flexible Data (CAN FD), and integrated Functional Safety (FuSa) primitives that allow the device to be deployed in ASIL-B/SIL-2 systems without an external watchdog MCU. The 28-pin UQFN (6 mm x 6 mm) package, designated "2N" in Microchip's suffix scheme, targets space-constrained designs such as digital power converters, motor drives, and sensor-fusion nodes. On-chip peripherals include multiple UARTS, SPI, I2C, an ADC, and configurable logic cells that let designers harden glue logic without external CPLDs. Typical applications span digital switch-mode power supplies, field-oriented control (FOC) motor drives, automotive mechatronics, and industrial LED lighting with adaptive thermal management. The dual-core partitioning is especially valuable when control loops must run uninterrupted while the master core handles housekeeping such as communication stacks, safety diagnostics, and HMI updates. With on-chip CAN FD, the device can serve directly in automotive and industrial backbones without an external transceiver controller. Designers should be aware that the dual-core architecture requires careful integration via Microchip's MPLAB Harmony framework; shared RAM regions must be protected with hardware semaphores to avoid race conditions. Programming and debug are supported through 4-wire ICSP on any of the multiple PGECx/PGEDx pin pairs.

In the product hierarchy it sits between a microcontroller (MCU) and a full DSP, combining 16-bit modified Harvard CPU architecture with a hardware multiplier-accumulator (MAC) that executes DSP operations in single cycles. The dsPIC33CH extends this further by integrating two DSC cores on one die. Key features include dual-core operation at 180MHz (main) and 200MHz (slave), 88KB of Flash split across the cores, 20KB of SRAM, 21 I/O pins, 3 serial interfaces, two 16-bit timers, and a high-resolution PWM module. Functional Safety (FuSa) features are integrated per IEC 60730 Class B, with hardware diagnostics that support safety-critical applications. The industrial temperature range of -40C to +85C is indicated by the I suffix. The architecture separates the cores with the slave having direct access to dedicated peripherals and shared SRAM via a mailbox and SFR-based inter-core communication. This division enables closed-loop control loops (such as power conversion) to run deterministically on the slave while the main core handles communication, housekeeping, and supervisory logic. The high-resolution PWM (ns-edge placement) and CAN-FD support target digital power conversion and motor control applications. Typical applications include digital switch-mode power supplies, field-oriented control (FOC) motor drives, LED lighting controllers, and industrial automation. The dual-core topology allows tight current-loop control on the slave while the main core runs telemetry and user interfaces. Functional Safety features also make this DSC attractive for appliances requiring IEC 60730 compliance, such as washing machines, dishwashers, and induction cooktops. When designing with this device, ensure that the inter-core mailbox is configured before the slave core is released from reset. The slave core's firmware must be loaded into PRAM and validated via the built-in CRC engine before the main core enables it; an uninitialized slave will read zeros from program memory and must not be permitted to drive outputs.

DSPIC33CH64MP202T-I/SS - Dual-Core DSC 100MHz 64KB Flash | Microchip

The Microchip DSPIC33CH64MP202T-I/SS is a 16-bit dual-core Digital Signal Controller (DSC) delivering 100 MHz main-core / 200 MHz slave-core performance with 64 KB Flash and 88 KB PRAM, housed in a 28-pin SSOP package. It targets high-end embedded control requiring deterministic motor-control loops combined with high-bandwidth housekeeping on a single chip. A Digital Signal Controller (DSC) is a hybrid device that merges a microcontroller (MCU) with a digital signal processor (DSP) on one die. In the broader taxonomy, a DSC sits between microcontroller (MCU) and digital signal processor (DSP); it belongs to the power-management-aware control class of MCUs that includes dedicated high-resolution PWM, op-amps, and analog comparators. The dsPIC33CH family extends this by integrating two dsPIC cores on one chip, allowing a master CPU to perform communication and supervisory tasks while a slave CPU executes time-critical control loops. This separation improves jitter and frees the main core to run operating systems, communications stacks, or user interfaces. Key features include a 200 MHz maximum slave-core clock, 64 KB Flash (88K x 8 organization), PRAM (Program RAM), up to 200 MIPS aggregate throughput, dedicated high-resolution PWM peripherals, integrated op-amps and comparators for current/voltage feedback, and CAN-FD support for industrial networking. Functional Safety (FuSa) features assist IEC 61508 / ISO 26262 development. The dual-core architecture reduces system latency and removes the need for an external companion MCU. The dsPIC33CH silicon uses a modified Harvard architecture with separate instruction and data paths, dual-ported SRAM, and a single-cycle 16x16 MAC DSP engine. Each core has independent register sets and interrupt controllers, enabling true parallel execution rather than time-slicing. The slave core can read/write shared RAM regions accessible by the master for inter-core messaging. Typical applications include digital power conversion (PFC plus LLC), sensorless and field-oriented motor control (FOC for PMSM/BLDC), automotive mechatronic actuators, solar micro-inverters, and industrial drives requiring tight current-loop bandwidth. The dual-core partition suits ASIL-B/C functional-safety architectures where one core runs the safety loop and the other runs the application. Design with this part by allocating deterministic control tasks to the slave core and user-interface or communication tasks to the master core; shared RAM buffers must be guarded against race conditions using the mailbox primitives documented in the dsPIC33CH family reference manual. Designers must also ensure the SSOP-28 PCB land pattern provides adequate copper pour for thermal dissipation; at 100 MHz plus 200 MHz dual-core activity, expect continuous dissipation in the 0.3-0.6 W range depending on peripheral enable state.

DSPIC33CH64MP205-E/PT

DSPIC33CH64MP205-E/PT - Dual-Core 16-bit MCU, 64KB Flash | Microchip

The Microchip Technology DSPIC33CH64MP205-E/PT is a dual-core 16-bit Digital Signal Controller (DSC) housed in a 48-lead TQFP (7x7 mm) package, featuring a master/slave architecture that allows one dsPIC33C core to function as the master while the second core operates as a slave for task partitioning in real-time control loops. The part integrates 64 KB of program Flash (with up to 88 KB across the family per third-party listings) and runs at up to 200 MHz internal MIPS performance derived from a 64 MHz external reference on each core. High-resolution PWM, CAN Flexible Data (CAN FD), and DSP acceleration combine to support switched-mode power, motor control, and digital-power feedback applications. The 48-TQFP footprint with 0.50 mm pitch supports compact PCB designs while keeping analog and digital I/O accessible for sensor interfaces. A Digital Signal Controller is a hybrid between a microcontroller (MCU) and a digital signal processor (DSP). It combines deterministic on-chip peripherals, interrupt-driven control, and DSP-style multiply-accumulate (MAC) execution in a single 16-bit Harvard core. In the product taxonomy, a DSC sits between an MCU and a DSP, inheriting from 16-bit microcontrollers and the broader category of embedded microcontrollers, and ultimately from semiconductors. Dual-core variants like the dsPIC33CH family add asymmetric multiprocessing (AMP), where the master handles communication, supervisory logic, and housekeeping while the slave core runs tightly-timed control loops, commutation algorithms, or DSP filters. Key differentiating features include dual-core architecture (master + slave on one die), high-resolution PWM for digital power conversion, integrated CAN FD for automotive-grade networking, dual dsPIC DSC cores capable of independent firmware, and 16-bit DSP engine with MAC and barrel shifter. Together, these reduce BOM cost by eliminating an external companion controller in power-conversion or motor-control designs. Architecturally, the dsPIC33CH uses separate buses for instruction and data fetch, an instruction cache, and deterministic interrupt latency. Each core has private peripherals and shared resources are arbitrated via hardware, allowing the slave to run a control loop with sub-microsecond jitter while the master executes housekeeping tasks without interference. Typical applications include digital switch-mode power supplies, field-oriented control (FOC) motor drives, wireless charging transmitters, LED lighting drivers, and industrial automation controllers. The wide operating voltage and integrated analog further extend its reach to renewable-energy inverters and automotive sensor conditioning. When designing with this device, allocate the master core to communication and housekeeping tasks (CAN, UART, supervisory logic), and the slave core to time-critical control loops (PWM, ADC sampling, commutation). Use the PGxECL/PGxFLT pins and high-resolution PWM mode for digital-power topologies.
