DSPIC33CH64MP205T-I/M4 - Dual-Core 200MHz DSC 88KB Flash | Microchip

The Microchip Technology DSPIC33CH64MP205T-I/M4 is a 16-bit dual-core Digital Signal Controller (DSC) with a primary master core running at 200 MHz and a secondary slave core at 180 MHz, delivering 88 KB of Flash and a 48-pin UQFN (6x6 mm) package with exposed thermal pad. A Digital Signal Controller (DSC) is a hybrid device that combines the deterministic control features of a microcontroller (MCU) with the high-throughput computational capabilities of a Digital Signal Processor (DSP). Positioned within the broader taxonomy as DSC -> microcontroller -> embedded processor -> semiconductor, the dsPIC33CH family is purpose-built for advanced closed-loop applications such as digital power conversion, motor control, and high-performance sensing where two independent cores can partition real-time control tasks from communication and housekeeping duties. Key features of the DSPIC33CH64MP205T-I/M4 include 88 KB (88K x 8) of program Flash, dual-core architecture enabling parallel task execution, high-resolution PWM with Flexible Data-rate CAN (CAN FD) support, and 3.3 V nominal supply operation across a 3.0 V to 3.6 V input range. The device is part of the Functional Safety (FuSa) capable dsPIC33CH family, providing integrated safety features suitable for ASIL-B/SIL-2-class designs. The exposed-pad UQFN-48 package supports efficient thermal dissipation at switching frequencies up to 200 MHz. The master/slave dual-core design enables one core to execute user code while the slave core handles time-critical peripheral control, eliminating software jitter on PWM updates. The integrated DSP engine executes single-cycle MAC instructions, accelerating sensorless motor-control algorithms, field-oriented control (FOC), and digital power compensation loops. With on-chip DMA, configurable logic cells (CLC), and high-speed analog comparators, the part targets designs that previously required an external FPGA or dedicated DSP coprocessor. Typical applications include digitally controlled switched-mode power supplies (SMPS), field-oriented motor control (FOC) for BLDC and PMSM motors, solar micro-inverters, and industrial automation drives. Designers choose this DSC when deterministic real-time response and DSP throughput are both required on a single chip. When designing with the DSPIC33CH64MP205T-I/M4, ensure that the master and slave cores are assigned well-defined roles during firmware bring-up and that the slave core's PCI (peripheral configuration) is locked before user code begins execution on the master. Use the exposed pad (EP) on the UQFN-48 package as the primary thermal path - it must be soldered to a sufficiently large copper pour. This page synthesizes distributor pricing, package-level drop-in alternatives, and practical design notes that supplement, rather than duplicate, the manufacturer datasheet content.

DSPIC33CH64MP205T-I/PT

DSPIC33CH64MP205T-I/PT - Dual-Core 200MHz DSC 64KB Flash | Microchip

The Microchip Technology DSPIC33CH64MP205T-I/PT is a dual-core 16-bit Digital Signal Controller (DSC) built on the dsPIC33CH family, integrating a 180 MHz master core and a 200 MHz slave core in a single 48-pin TQFP (7x7 mm) package. It provides 88 KB of program Flash (64 KB master + 24 KB slave) and combined RAM of 16 KB master + 4 KB slave, with additional PRAM for safety monitoring. The 'T' suffix indicates tape-and-reel packaging and the 'I' industrial temperature grade spans -40C to +85C at a 3.0V to 3.6V supply range. A digital signal controller (DSC) combines a microcontroller with a hardware DSP engine, sitting in the hierarchy DSC -> MCU -> embedded processor -> semiconductor. The dsPIC33CH family elevates this concept by placing TWO DSC cores on-chip: a master that runs the application and a slave that handles time-critical peripherals, control loops, or Functional Safety (FuSa) housekeeping. This dual-core architecture removes the latency jitter that single-core MCUs suffer when the main loop is interrupted by communication or ADC servicing, and it enables fault-detected architectures compliant with IEC 61508 SIL 2/SIL 3 functional-safety standards. Key features include 32 KB instruction cache, hardware multipliers (16x16 single-cycle), 12-bit 3.5 MSPS ADC, PWM with 250 ps resolution, up to 12 general-purpose DMA channels, and a CAN-FD peripheral set. The slave core runs independently of the master and can access dedicated peripheral regions, making it ideal for digital power conversion, motor control, advanced sensing, and redundant safety monitoring within a single device. The device targets high-performance switched-mode power supplies, field-oriented motor control (FOC), and automotive/industrial functional-safety subsystems. The dual-core configuration uses a single 3.3 V rail and shares an external crystal/PLL reference between cores. The master core typically handles application code and user interface, while the slave core manages real-time control loops, ADC sampling, or self-diagnostic routines. This division of labor reduces software real-time complexity and removes the need for an external companion MCU in many designs. Typical applications include digital switch-mode power supplies (SMPS) with active PFC, field-oriented control (FOC) motor drives for industrial BLDC and PMSM motors, on-board chargers and DC-DC converters for xEV powertrains, and functional-safety subsystems requiring redundant compute (ISO 26262 ASIL B/C, IEC 61508 SIL 2/3). The integrated PRAM and dual watchdog architecture support safety integrity level certification without an external companion IC. When designing with this device, treat the two cores as separate compile targets with their own linker scripts and map firmware dedicated IPs (FDCI) for inter-core mailbox communication. Provide ample decoupling (100 nF + 4.7 uF) around both AVDD and VDD pins and keep the trace length to the PLL loop filter under 10 mm to minimize jitter on the 200 MHz slave clock.

The Microchip Technology DSPIC33CH64MP206-E/MR is a dual-core 16-bit Digital Signal Controller (DSC) integrating a master and a slave dsPIC33C core on a single die. The master core runs at 180 MHz (200 MIPS) while the slave core operates at 200 MHz, paired with 64 KB of Flash, 8 KB of SRAM and 16 KB of PRAM in a 64-pin QFN (9x9 mm, MR) package with an exposed thermal pad. The 'E' suffix indicates an extended temperature grade of -40C to +125C for industrial environments. A Digital Signal Controller (DSC) is a hybrid class of microcontroller that fuses a deterministic MCU pipeline with a single-cycle DSP engine. The dsPIC33CH family builds on this with dual-core heterogeneous partitioning: one core supervises the system, runs communications and housekeeping, while the second core deterministically executes time-critical DSP loops. Architecturally the chip sits in the power-management / motor-control tier of the embedded hierarchy - DSC -> microcontroller -> embedded processor -> semiconductor. Key features include dedicated high-resolution 16-bit PWM channels optimized for digital power conversion, integrated CAN Flexible Data (CAN FD) peripherals, up to 12-bit ADC at 3.5 Msps, configurable logic cells, and an integrated op-amp. Functional Safety (FuSa) support libraries and Class B/Safety diagnostics are bundled. The 64-pin QFN package provides compact board footprint while preserving analog pinout density. Typical applications include wireless charging transmitters, server and telecom SMPS, BLDC/PMSM motor control, drone ESCs, automotive sensor fusion, and digital LED lighting. The dual-core architecture lets firmware split time-critical control loops from user-interface code without task-switching jitter. When designing with this part, populate the exposed thermal pad with a continuous copper plane and stitch vias to inner ground layers; at 200 MIPS the slave core can pull substantial current during heavy DSP bursts.

DSPIC33CH64MP206-I/PT

DSPIC33CH64MP206-I/PT - Dual-Core 16-bit DSC 64KB Flash | Microchip

The Microchip Technology DSPIC33CH64MP206-I/PT is a dual-core 16-bit Digital Signal Controller (DSC) featuring a master/slave architecture, 64KB Flash, and high-resolution PWM, housed in a 64-pin TQFP (10x10) package. The main (master) core and the secondary (slave) core can operate at up to 180 MHz / 200 MIPS, giving the device a combined DSP throughput typically used in tightly-coupled closed-loop control tasks such as digital power conversion and field-oriented motor control. What is a Digital Signal Controller (DSC)? A DSC is a hybrid device that fuses a microcontroller (MCU) with a Digital Signal Processor (DSP). It inherits the MCU's deterministic interrupt handling, peripheral set, and C-friendly toolchain, while adding single-cycle MAC units, barrel shifters, and saturating arithmetic for high-speed signal processing. This places DSCs above generic MCUs but below standalone DSPs in the compute hierarchy, and as part of the broader power-management and motor-control IC landscape they coexist with FPGAs and Cortex-M microcontrollers. Key features of the DSPIC33CH64MP206 include integrated high-resolution PWM (typically 250 ps edge placement), CAN FD, four 12-bit ADC cores with up to 3.5 MSPS each, four op-amps/comparators, and the dual-core design in which the slave core can offload time-critical DSP loops from the master. A 64KB program Flash, 8KB SRAM, 1KB PRAM for inter-core messaging, and 72 KB total address space provide room for state machines and PID control loops in motor drive and digital power firmware. Architecturally the master core handles housekeeping, communication stacks (UART/SPI/I2C/CAN), and supervisory state machines, while the slave core is dedicated to a single high-priority task (sensorless FOC, digital PFC, LLC control loop, etc.) with its own interrupt vector table, register set, and tightly-coupled PRAM mailbox to the master. The device is fabricated on a CMOS process and is offered in -40C to +85C industrial temperature grade in this -I/PT variant. Typical applications for the DSPIC33CH64MP206 include wireless charging transmitters, server/telecom SMPS and PFC stages, drone BLDC motor ESCs, automotive sensor fusion front-ends, and digital LED drivers. It is particularly well suited to any closed-loop control loop where a small, fast slave core can guarantee deterministic sub-microsecond control regardless of what the master is doing. When designing with this part, allocate the slave core to one mission-critical DSP task only; do not use it as a general-purpose second CPU. Use the PRAM mailbox and interrupt-driven handshake for inter-core messaging rather than shared globals, and review the dsPIC33CH family reference manual's slave-bootstrap sequence to avoid lockup at startup. This page synthesizes the Microchip datasheet with distributor pricing, same-family drop-in alternatives, and design notes that go beyond the datasheet's typical-application section, with the goal of giving an engineer a single decision-ready page for the DSPIC33CH64MP206-I/PT.

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.

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 high-resolution PWM module delivers sub-nanosecond duty-cycle resolution for precision power conversion, and the CAN Flexible Data (CAN FD) interface supports modern automotive and industrial networks. Eight DMA channels and multiple serial ports (UART, SPI, I2C) round out the peripheral set. Architecturally, the 16-bit modified Harvard pipeline with DSP multiply-accumulate instructions enables efficient execution of compensator algorithms such as 3P3Z and PID loops at switching frequencies well above 100 kHz. Dual-core partitioning lets engineers update firmware on one core without disturbing the safety-critical control loop on the other. Typical applications include digital power supplies (server PSU, telecom rectifiers, wireless charging), brushless DC and PMSM motor control (drones, industrial drives), automotive sensors, and power factor correction stages. For design, allocate the secondary core to the switching control loop and reserve the primary core for CAN FD communication and supervisory logic; the E-grade temperature rating requires verifying junction temperature against the QFN thermal pad copper area.

The 100 MHz core closes high-bandwidth current loops that slower MCUs cannot. When designing with this device, connect all VDD and VSS pins, and pair PGECx/PGEDx pins correctly for ICSP programming, since mixing pairs from different debug channels will cause programming to fail. This page synthesizes distributor pricing, drop-in family alternatives, and practical design notes not found in the manufacturer datasheet.
