DSPIC33CH64MP206T-I/MR - Dual-Core 16-Bit DSC, 88KB Flash | Microchip

The Microchip Technology DSPIC33CH64MP206T-I/MR is a dual-core 16-bit Digital Signal Controller (DSC) delivering up to 200 MHz CPU speed with 88 KB of Flash program memory and a 64-pin QFN (9x9 mm) package. It features a master/slave architecture where the master core runs the application code and the slave core handles dedicated time-critical tasks such as high-resolution PWM and motor-control loops. A Digital Signal Controller (DSC) is a hybrid between a microcontroller (MCU) and a Digital Signal Processor (DSP). It combines deterministic on-chip peripherals, interrupt latency, and bit-level I/O control with hardware multiply-accumulate (MAC) and barrel shifter blocks, enabling single-cycle math on fractional data. The dsPIC33CH family specifically adds a second independent core inside the same silicon die, partitioning firmware into a high-level supervisory core (master) and a real-time control core (slave) that communicate through a tightly-coupled dual-core mailbox. This hierarchical topology belongs to the broader embedded control category: DSC -> MCU family -> embedded processor -> semiconductor device. Key features include 88 KB Flash with Error Correction Code (ECC), up to 16 KB RAM split between the cores, a 12-bit ADC with up to 3.5 Msps conversion, high-resolution PWM (250 ps edge placement), CAN Flexible Data (CAN FD) support, and a functional-safety (FuSa) hardware path qualified to assist ISO 26262 system designs. The part is rated for the industrial -40C to +85C temperature range and ships in a tape-and-reel-friendly 64-pin QFN with thermal pad for 1.7 W typical dissipation headroom. Architecturally the slave core can be programmed and debugged independently, enabling software teams to develop the control algorithm separately from the supervisory logic. Integrated op amps, comparators, and dead-time generators reduce external analog components on the PCB, which is critical for compact motor-drive and digital-power stages. Typical applications include digital switch-mode power supplies, field-oriented control (FOC) motor drives, solar microinverters, wireless charging transmitters, and functional-safety industrial controllers. The dual-core partition also suits lighting ballast and Class-D audio amplifier designs. When designing with this device, allocate the master core to communication stacks (UART, SPI, CAN FD) and the slave core to closed-loop control tasks. Use a 4-layer PCB stack-up to keep the exposed thermal pad soldered to a continuous ground pour for proper heat extraction under sustained PWM load.

The Microchip Technology DSPIC33CH64MP206T-I/PT is a 16-bit dual-core Digital Signal Controller (DSC) in the dsPIC33CH family, integrating a 180 MHz main core and a 200 MHz auxiliary core with 88 KB of PRAM-programmable Flash in a 64-pin TQFP (10x10 mm) package. The 'T' suffix denotes tape-and-reel packaging and 'I' indicates the industrial -40°C to +85°C temperature grade, while the -I/PT suffix combination is supplied in a surface-mount 64-TQFP with 0.5 mm pitch. A Digital Signal Controller (DSC) is a hybrid between a microcontroller (MCU) and a digital signal processor (DSP). It combines deterministic interrupt-driven control peripherals typical of MCUs with high-throughput DSP math capabilities. Within the system hierarchy, a DSC sits between a microcontroller and a dedicated DSP, offering single-cycle MAC, hardware loop buffers, and zero-overhead looping. The dsPIC33CH family specifically adds a heterogeneous dual-core topology (main + auxiliary), enabling real-time partitioning of control loops and communication stacks onto physically isolated cores. The main core runs the application while the auxiliary core handles time-critical sub-tasks such as power-converter feedback loops, motor commutation, or custom peripherals. Key features include up to 200 MHz operation on the auxiliary core (180 MHz on the main core), DSP engine with single-cycle 16x16 MAC, 88 KB Flash, up to 16 KB SRAM, configurable logic cells, high-speed PWMs, 12-bit ADCs at 3.5 MSPS, and Functional Safety (FuSa) features for ASIL-B/SIL-2 capable systems. The device supports 3.0 V to 3.6 V single-supply operation and integrates CAN-FD, I2C, SPI, UART, and SENT peripherals for automotive and industrial connectivity. Architecturally, the dual-core topology uses tightly-coupled shared memory and mailbox interrupts to minimize latency between cores. The auxiliary core can access main-core peripherals through a programmable register bus, which simplifies system partitioning. The DSP engine uses dual-operand fetch and a 40-bit accumulator to support high-precision control loops without software overhead, achieving deterministic sub-microsecond response times critical for digital power conversion. Typical applications include digital switch-mode power supplies (SMPS), high-performance motor control (PMSM, BLDC), wireless charging, LED drivers, server/telecom power converters, automotive sensor fusion, and drones. The device's deterministic dual-core architecture suits safety-critical applications where one core performs diagnostics while the other runs the application. When designing with the DSPIC33CH64MP206T-I/PT, allocate Flash and RAM budgets across both cores and use MPLAB Code Configurator (MCC) for peripheral setup. The auxiliary core's PRAM allocation must be planned at link time because Flash is partitioned between the two cores. A 4-layer PCB with continuous ground plane is recommended for the 200 MHz signal paths and ADC reference integrity. This page synthesizes distributor pricing, dual-core partition notes, and FuSa-grade design considerations not always captured in the manufacturer datasheet.

The Microchip Technology DSPIC33CH64MP208T-I/PT is a 16-bit dual-core Digital Signal Controller (DSC) that combines a 200 MHz master dsPIC core with a 180 MHz slave dsPIC core in a single 80-pin TQFP (12x12) package. The device integrates 88 KB of Flash program memory, 20 KB of SRAM, and 4 KB of auxiliary Flash, targeting high-end embedded control and functional safety (FuSa) applications. A Digital Signal Controller (DSC) is a hybrid MCU/DSP class of microcontroller that integrates a microcontroller control unit with a Digital Signal Processor (DSP) engine. In the taxonomy of semiconductors, a DSC sits between a microcontroller (MCU) and a Digital Signal Processor (DSP), inheriting deterministic interrupt-driven control from MCUs and high-throughput math pipelines from DSPs. The dsPIC33CH family extends this with a heterogeneous dual-core architecture where the master core runs the application and the slave core handles time-critical or safety housekeeping, reducing jitter on motor-control and digital-power loops. Key features include 70 MIPS performance on the master core, dedicated peripherals such as High-Speed PWM (12.5 ns resolution), 12-bit ADC at up to 3.5 Msps, 12-bit DAC, four analog comparators, and three DMA engines. Functional-safety diagnostics include dual-window watchdog timers, ECC on Flash/RAM, and a configurable Fault Collection Unit (FCU). The 80-pin TQFP package offers 69 I/O pins with 5V-tolerant inputs and operating temperature range of -40C to +85C for the industrial grade -I variant. Architecturally, each core has independent register sets, interrupt controllers, and DMA channels, communicating through hardware mailboxes and shared memory. The slave core can also be clock-gated or independently reset, supporting selective activation for power-conscious designs. The chip supports 3.0V to 3.6V single-supply operation and integrates a PLL for flexible clock generation. Typical applications include digital switched-mode power supplies (SMPS), field-oriented control (FOC) motor drives for BLDC/PMSM, automotive sensors and actuators, solar micro-inverters, and LED lighting controllers. The dual-core topology is particularly suited to functional-safety systems requiring ASIL-B or SIL-2 certified firmware partitioning. Designers should note that two independent firmware images are required (one per core) and that the slave-core debug port uses dedicated pins that may need to be reassigned to GPIO in production. The 12x12 mm TQFP footprint allows PCB layouts with conventional 0.5 mm pitch routing and 4-layer stack-ups. This page combines manufacturer datasheet values, distributor pricing tiers, drop-in alternatives, and PCB design notes that go beyond the datasheet, giving engineers a single reference for sourcing and designing with the dsPIC33CH64MP208 family.

The two cores communicate through a dedicated shared-RAM interface, allowing one silicon device to replace a two-chip controller/processor pairing. Key features include the dual-core asymmetric architecture optimized so the slave core is designed for sophisticated control algorithms, CAN Flexible Data (CAN FD) for automotive and industrial networking, and high-resolution PWM peripherals engineered for switching power supplies and motor drives. The -I/PT ordering code denotes the industrial temperature grade (-40C to +125C) in a surface-mount TQFP package suitable for automated assembly. Architecturally, the master core manages communications, housekeeping and system supervision while the slave core executes control-loop code with minimal jitter. This partitioning reduces interrupt latency pressure on the control loop compared with a single-core design, which is why the dsPIC33CH family is optimized for high-performance digital power conversion. Typical applications include digital power supplies, server and telecom power, wireless charging, drone motor control, automotive sensors, and industrial inverters where CAN FD networking and precise PWM timing are required. Design consideration: budget your flash carefully - this 64 KB variant is the smallest MP506 memory option, so pin-compatible 128 KB, 256 KB and 512 KB siblings in the same 64-TQFP footprint exist for firmware growth without PCB redesign.

The Microchip Technology DSPIC33CH64MP506T-I/PT is a 16-bit dual-core digital signal controller (DSC) with a 100 MHz operating speed, 64 KB of program flash memory, and CAN FD connectivity, housed in a 64-pin TQFP (10x10 mm) package. A digital signal controller combines the computational horsepower of a digital signal processor (DSP) with the peripheral integration and control-oriented architecture of a microcontroller (MCU). In the embedded systems hierarchy, the dsPIC33CH sits within the 16-bit DSC class between general-purpose MCUs and full 32-bit DSPs, making it a power management IC companion for digitally controlled power conversion and motion systems. Key features of the dsPIC33CH family include an asymmetric dual-core architecture: a primary core running up to 100 MHz for general control and supervision, plus an independent secondary core dedicated to time-critical loops. The family integrates high-resolution PWM (HRPWM) with sub-nanosecond effective resolution, CAN Flexible Data-rate (CAN FD) for modern in-vehicle and industrial networks, and multiple serial interfaces. The MP506 variant provides 64 KB of flash and dedicated PRAM for inter-core communication. Architecturally, the two cores can run different code at different clock speeds, allowing engineers to partition safety-critical or high-frequency control algorithms (such as peak current-mode power conversion) onto the secondary core while the primary core handles communication, housekeeping, and human-interface tasks. Debug of both cores is supported simultaneously through standard Microchip tools. Typical applications include digital power supplies, wireless charging transmitters and receivers, server PSU and telecom rectifier control, drone electronic speed controllers, and automotive sensor modules where CAN FD and high-resolution PWM are required. A key design consideration: the 3.0V to 3.6V supply range requires a clean 3.3V rail, and decoupling capacitors should be placed close to each VDD pin on the TQFP-64 footprint.

DSPIC33CH64MP508-I/PT - Dual-Core 16-bit DSC, CAN FD | Microchip

The Microchip Technology DSPIC33CH64MP508-I/PT is a 16-bit dual-core Digital Signal Controller (DSC) from the dsPIC33CH family with 64 KB of program Flash, 20 KB of data RAM, integrated CAN Flexible Data (CAN FD) and high-resolution PWM, housed in an 80-pin TQFP (12x12 mm, 0.5 mm pitch) surface-mount package rated for -40C to +85C industrial operation. A Digital Signal Controller combines the computational throughput of a DSP with the peripheral integration and deterministic control of a microcontroller. Within the power-management hierarchy, a DSC sits above a standard MCU for closed-loop control tasks: it executes control-loop mathematics (PID, compensators, transforms) at kHz rates while simultaneously servicing fast analog peripherals. The dsPIC33CH extends this concept by placing two independent dsPIC cores in one chip, partitioning system management from hard real-time control. The dsPIC33CH architecture assigns distinct roles to each core. The Master core handles system supervision, communication stacks and user interface tasks, while the Slave core is dedicated to time-critical loops such as power-conversion or motor-control algorithms. This partitioning lets developers tune the Slave core independently for loop latency while the Master manages CAN FD networking, diagnostics and housekeeping. The tightly coupled 16-bit DSP engine with hardware multiply-accumulate, plus eight DMA channels, sustains high-throughput data movement without CPU intervention. Key peripheral resources include multiple high-resolution PWM modules with nanosecond-class resolution for switching converters, serial peripherals for multi-protocol connectivity, and CAN FD for automotive and industrial networking. DigiKey lists the family as Functional Safety (FuSa) supported, relevant to safety-oriented designs. Typical applications are high-performance digital power supplies, wireless charging, server power, motor control inverters, drones and automotive sensors, where dual-core partitioning isolates the control loop from communication overhead. A key design consideration is power supply quality: the 3.3V core and I/O rails require proper decoupling, and the high-resolution PWM outputs demand clean grounding to avoid switching-noise coupling into ADC readings.
