DSPIC33CH128MP206-I/MR - 16-Bit Dual-Core 100MHz DSC | Microchip
MPN: DSPIC33CH128MP206-I/MR ✓ AktifDSPIC33CH128MP206-I/MR Ringkasan
A Digital Signal Controller (DSC) is a hybrid architecture that merges a microcontroller (MCU) with DSP-class multiply-accumulate (MAC) capability. The dsPIC33CH family is the dual-core generation of Microchip's dsPIC33 DSCs, designed for applications that need a control host and a dedicated computation engine on one chip. The hierarchy is: dsPIC33CH DSC -> digital signal controller -> 16-bit embedded processor -> microcontroller family.
Key features of the DSPIC33CH128MP206 include high-resolution PWM (typically 250 ps resolution) for digital power topologies, multiple UART/SPI/I2C/CAN interfaces, 12-bit ADCs with dual sample-and-hold for simultaneous current/voltage sampling, configurable logic cells, and built-in Functional Safety (FuSa) features suitable for safety-critical designs. The dual-core split allows the slave core to handle time-critical closed-loop control while the master runs communication stacks and supervisory logic.
The architecture separates concerns cleanly: the master core hosts the application, OS, and housekeeping tasks, while the slave executes deterministic control code from a dedicated PRAM region with its own interrupt context. Inter-core communication uses dedicated mailbox RAM and hardware semaphores, removing the need for soft task synchronization.
Typical applications include digitally-controlled switch-mode power supplies (PFC, LLC, full-bridge converters), Field-Oriented Control (FOC) motor drives, wireless charging transmitters, digital LED drivers, server/telecom power bricks, and drones/BLDC drives in drones and automotive sensors.
When designing with this part, allocate the slave core's PRAM region and dual-sample-and-hold ADC channels carefully, ensure the exposed pad is soldered to a sufficient copper pour for thermal dissipation, and verify the high-resolution PWM timing against the switching frequency of your converter.

Aplikasi Umum
DSPIC33CH128MP206-I/MR cocok untuk 6 aplikasis: Digital PFC and LLC Power Supply, Field-Oriented Control (FOC) Motor Drive, Wireless Power Transmitter, Server and Telecom Power Brick, Drone BLDC ESC Controller, Automotive Sensor Signal Conditioning.
Digital PFC and LLC Power Supply
The DSPIC33CH128MP206-I/MR is well-suited to digital PFC plus LLC power-converter stages. Its dual-core split assigns the 200 MHz slave core to the high-speed current-control loop while the 100 MHz master handles PFC average-current mode, housekeeping, and PMBus telemetry. The 250 ps high-resolution PWM provides the edge placement accuracy required for totem-pole bridgeless PFC at 100 kHz switching frequency, eliminating the need for external delay lines. Compared with a discrete MCU plus CPLD partition, the dsPIC33CH integrates both cores on one die, reducing propagation jitter and BOM cost by roughly 25-30% in a 1 kW telecom brick.

Field-Oriented Control (FOC) Motor Drive
For FOC motor drives on BLDC and PMSM motors, the DSPIC33CH128MP206-I/MR excels by dedicating the 200 MHz slave core to the Park/Clarke transformations and the SVM modulator that runs at PWM frequency. The 12-bit ADC with dual sample-and-hold captures phase currents simultaneously within a few hundred nanoseconds, enabling sinusoidal control loop closure inside one PWM period. The master core handles CAN-FD comms, encoder feedback, and fault management without disturbing the control timing.

Wireless Power Transmitter
The DSPIC33CH128MP206-I/MR is ideal for Qi and AirFuel wireless-power transmitters operating at 100-205 kHz. The slave core's deterministic 200 MHz execution lets the resonator-control loop adjust inverter frequency and duty cycle every 5 microseconds while maintaining precise foreign-object detection (FOD) timing. The high-resolution PWM provides the dead-time control essential for zero-voltage switching (ZVS) on the primary coil, reducing switching losses and EMI below CISPR 11 limits.

Server and Telecom Power Brick
In 48 V-input server/telecom power bricks delivering 12 V at 50-100 A, the DSPIC33CH128MP206-I/MR's FuSa features and dual-core separation support paralleled converter phases with deterministic current-sharing. The slave core runs per-phase current-mode control at 200 MHz, while the master orchestrates OR-ing, hot-swap, and PMBus telemetry. AEC-Q100 automotive-derated use cases in 12 V battery systems also map well to this part's -40 C to +85 C industrial grade.

Drone BLDC ESC Controller
Drone Electronic Speed Controllers (ESCs) running at 24-48 V with 100 A peak currents benefit from the DSPIC33CH128MP206-I/MR's deterministic FOC control at 24 kHz PWM. The slave core handles fast current loop closure within a single 41 microsecond PWM period, leaving the master free to run DShot/OneShot protocol decoding and battery telemetry. The 64-pin QFN package keeps the board footprint small enough for 20x20 mm ESC designs.

Automotive Sensor Signal Conditioning
For automotive sensor modules that need deterministic signal processing with safety integrity, the DSPIC33CH128MP206-I/MR's FuSa support and dual-core architecture provide the foundation. The slave core executes sensor linearization and self-test routines while the master handles CAN-FD diagnostics. Combined with the -40 C to +125 C extended-temperature grade (DSPIC33CH128MP206-E/MR), the family covers a wide range of in-cabin and under-hood automotive sensor applications.

Catatan Desain
Estimated: At 200 MHz slave core + 100 MHz master core running full code, the QFN-64 EP device dissipates roughly 0.5-0.8 W. The exposed pad (EP) MUST be soldered to a thermal pad with at least 25 mm^2 of copper pour to keep junction temperature below 100 C at 85 C ambient. Insufficient thermal copper will cause the device to throttle or trigger thermal shutdown during heavy FOC workloads.
Place a 100 nF decoupling capacitor as close as possible to each VDD pin pair (5 pairs on this package), and a single 10 uF bulk capacitor near the package. The exposed pad must have at least 9 thermal vias (0.3 mm diameter) connecting to an internal ground plane for heat sinking. Route the high-speed ADC analog inputs (AN0-AN5) away from PWM switching traces to avoid coupling noise into current measurements.
Do not assume the slave core boots automatically - it must be explicitly launched by the master core using the SLCMD register and Mailbox interrupt sequence. Also, the high-resolution PWM dead-time control is sensitive to GPIO drive strength configuration; verify PGSTAT registers after startup to confirm the PWM edges are correctly aligned. Per the Microchip datasheet, the ICSP programming pins (PGEC1/PGED1) need 4.7 kohm pull-up resistors on PGECx for reliable in-circuit programming.
Separate analog and digital ground planes on the PCB and join them at a single point near the AVSS pin. Route crystal oscillator traces (OSCI/OSCO) with guard-ground traces on both sides to avoid noise injection. Keep PWM traces short and matched within 5 mm to maintain timing alignment between high-side and low-side FETs.
