DSPIC33CH128MP202-E/2N Übersicht
A Digital Signal Controller (DSC) is a hybrid between a microcontroller (MCU) and a Digital Signal Processor (DSP). Like an MCU, it integrates Flash, RAM, peripherals, and interrupt control on-chip; like a DSP, it adds a single-cycle MAC engine, dual Harvard buses, and DSP-specific accumulators. DSCs sit in the hierarchy MCU -> DSC -> DSP -> embedded processor, combining deterministic control with high-throughput math. The dsPIC33CH family in particular introduces dual-core capability, a sub-family of digital signal controllers aimed at high-end embedded control.
Key features include high-resolution PWM (250 ps), CAN Flexible Data (CAN FD), a 12-bit ADC with up to 3.5 MSPS, four analog comparators with 32 ns response time, and functional-safety (FuSa) hardware support for IEC 61508 SIL 2 capable designs. The integrated op amps, DAC, and configurable logic cells reduce external component count in motor drive and digital power stages. The dsPIC33CH family also provides high-speed analog peripherals including a 4 ADC S&H pair and a 5 ns PWM-to-PWM synchronization chain.
Architecturally, the master/slave cores share selected peripherals and inter-core FIFOs provide deterministic command and data exchange. The slave core can execute dedicated tasks such as closed-loop control without interrupting the master's communication stack, reducing jitter and improving loop bandwidth. This makes the dsPIC33CH well-suited for designs where a single-core controller struggles with deterministic task scheduling.
Typical applications include wireless charging, server power supplies, drone flight controllers, and automotive sensor interfaces. In automotive body and powertrain ECUs the dual-core split simplifies ASIL-B/C decomposition, while in industrial motor drives it separates current-loop control from CAN/CAN-FD diagnostics. The 28-pin UQFN footprint allows compact power-converter and BLDC motor PCB layouts.
When designing with this part, route the slave core's high-speed PWM outputs close to the UQFN thermal/epitaxial pad to minimize parasitic inductance. Verify the linker placement of code into the slave PRAM region using MPLAB X IDE, since incorrect mapping disables the secondary core. Decouple AVDD/AVSS analog rails with a dedicated 1uF/0.1uF pair placed within 3 mm of the analog pins.

Typische Anwendungen
DSPIC33CH128MP202-E/2N ist geeignet für 6 Anwendungs: Wireless Charging Power Conversion, Server Power Supply Digital Control, BLDC / PMSM Motor Control, Drone Flight Controller / ESC, Automotive Sensor Fusion ECU, Industrial PLC and Process Control.
Wireless Charging Power Conversion
The DSPIC33CH128MP202-E/2N's dual-core architecture is purpose-built for resonant wireless charging transmitters, where the slave core runs the 100-200 kHz zero-voltage-switching (ZVS) control loop with sub-microsecond jitter while the master core handles Qi/BPP/EPP protocol negotiation, foreign-object detection (FOD), and BLE pairing. The 250 ps high-resolution PWM aligns dead-band insertion to within nanoseconds across the half-bridge gate drivers, reducing switching losses below 5 W per kW. Integrated 12-bit ADC samples the resonant tank current and primary coil voltage synchronously to the PWM carrier for cycle-by-cycle current-mode control. CAN FD is leveraged for in-vehicle wireless charging modules to report diagnostic state to the central body controller.
Empfohlen
Server Power Supply Digital Control
In 80 PLUS Titanium server PSU and 48V-to-POL converter designs, the DSPIC33CH128MP202-E/2N executes the average-current-mode PFC and phase-shifted full-bridge control loops on its slave core at fixed 4-microsecond intervals, eliminating master-core interrupt jitter that would otherwise degrade THD below 0.95 PF. The 12-bit 3.5 MSPS ADC samples input voltage, inductor current, and output voltage within a single switching cycle for feed-forward correction across 85-264 VAC input. The functional-safety hardware supports IEC 61508 SIL 2 overvoltage and overcurrent protection paths required in telecom and data-center PSUs.
Empfohlen
BLDC / PMSM Motor Control
Field-oriented control (FOC) of three-phase PMSM motors benefits from the DSPIC33CH128MP202-E/2N's slave-core determinism, which executes the current-regulation loop at 20 kHz with single-microsecond latency regardless of CAN or UART traffic on the master core. The high-resolution PWM provides 250 ps edge placement for sinusoidal commutation, reducing torque ripple and audible noise below 2 kHz operating range. The 12-bit ADC's 3.5 MSPS throughput captures all three phase currents simultaneously using the integrated 4 S&H pair, eliminating sequential-sampling skew in sinusoidal FOC. The -40 C to +125 C extended range supports under-hood and industrial servo applications.
Empfohlen
Drone Flight Controller / ESC
The DSPIC33CH128MP202-E/2N powers the electronic-speed-controller (ESC) half of drone flight platforms, where the slave core runs the 8-32 kHz BLDC motor FOC loop while the master core maintains DShot/OneShot CAN-FD communication to the flight controller. With its small 6x6 mm UQFN footprint, the device fits inside miniaturized 20 mm x 20 mm 4-in-1 ESC PCBs. The functional-safety hardware and high-resolution PWM improve motor response time during aggressive maneuvers, reducing propwash-induced attitude errors. The 200 MHz slave-core clock headroom allows forward-looking implementation of model-predictive control (MPC) algorithms on next-generation flight controllers.
Empfohlen
Automotive Sensor Fusion ECU
Automotive sensor fusion ECUs such as 6-axis IMU+GNSS or battery-management junction boxes benefit from the DSPIC33CH128MP202-E/2N's deterministic slave core, which executes Kalman filter updates at 1 kHz while the master core handles CAN-FD bus traffic at 2 Mbps. The extended -40 C to +125 C temperature range meets AEC-Q100 Grade 1 expectations for under-hood and chassis placement. Functional-safety hardware supports ASIL-B decomposition between the master and slave cores, allowing one core to perform diagnostic checks on the other during run-time. The on-chip 12-bit ADC digitizes up to 16 analog sensor channels directly, reducing external ADC BOM.
Empfohlen
Industrial PLC and Process Control
In PLC and process-control I/O modules, the DSPIC33CH128MP202-E/2N's dual-core design isolates the IEC 61131-3 user-program execution on the slave core from Modbus TCP and EtherCAT communication firmware on the master core, improving scan-time jitter to within +/- 1 microsecond for deterministic motion sequencing. The 250 ps PWM drives high-precision stepper and servo control outputs, while the 12-bit ADC acquires 4-20 mA analog inputs through integrated op amps. Functional-safety hardware allows compliance with IEC 61508 SIL 2 for safety-related process loops.

Designhinweise
The DSPIC33CH128MP202-E/2N requires separate analog (AVDD) and digital (VDD) supply rails, both within 3.0 V to 3.6 V. Decouple VDD with a 10 uF bulk + 0.1 uF ceramic pair placed within 5 mm of the package; route AVDD through a ferrite bead from VDD and decouple with a 1 uF + 0.1 uF ceramic pair within 3 mm of the analog pins (AVDD, AVSS). The UQFN central epitaxial pad must be soldered to the ground plane to achieve the rated thermal performance and provide low-impedance ground return.
Route the high-speed PWM outputs (PWM1H/L through PWM3H/L on pins 5-10) using matched-length traces and avoid 90-degree bends. Place the gate drivers within 25 mm of the PWM pins to minimize parasitic inductance below 10 nH. Use a 4-layer PCB with a continuous ground plane beneath the device; the central UQFN pad requires at least 8 thermal vias (0.3 mm diameter, 0.5 mm pitch) to ground. Keep the crystal or external clock traces short and shield them with ground pours on both sides.
Do not assume the slave core initializes automatically - the master core must explicitly unlock and start the slave via the MSI (Master-Slave Interface) registers at boot. PRAM code sections must be linked into the slave's PRAM memory region using MPLAB X IDE's memory configuration; incorrect placement causes the slave core to execute garbage instructions. The slave core cannot access the master's Flash directly; shared data must use inter-core FIFOs (MSI RAM windows). Always review the silicon errata DS80000795 before finalizing firmware.
The CAN FD bus requires a 120 ohm termination resistor at each end of the bus segment, with stubs kept below 50 mm. For high-speed 2 Mbps CAN FD, place the transceiver within 10 mm of the DSPIC33CH128MP202-E/2N's C1TX/C1RX pins and use impedance-controlled routing (typically 100-ohm differential). Analog input traces to AN12-AN17 should be guarded by ground traces and kept away from PWM switching signals to prevent capacitive coupling above 10 pF, which would degrade ADC accuracy below 10 ENOB.
Compliance-Informationen
RoHS compliant per Microchip product page. The -E temperature grade extends to +125 C for industrial and under-hood automotive use; AEC-Q100 Grade 1 conformance is documented in the device qualification report. Functional-safety hardware supports IEC 61508 SIL 2 capable designs, but final SIL/ASIL classification is integrator responsibility.
