DSPIC33CH128MP508T-I/PT Présentation
A Digital Signal Controller (DSC) is a hybrid device that combines the deterministic interrupt response and peripherals of a microcontroller (MCU) with the multiply-accumulate (MAC) engine, barrel shifter, and DSP library support of a Digital Signal Processor (DSP). The dsPIC33CH family extends this concept by adding a second on-chip dsPIC core, allowing complex control tasks such as field-oriented control (FOC) of multiple motors, digital power conversion, and functional-safety housekeeping to coexist on a single silicon die. In the broader taxonomy the part sits as: DSC -> microcontroller -> embedded processor -> semiconductor IC.
Key features include 152 KB Flash program memory organized as 128 KB on the master core plus 24 KB shared with the slave core, CAN FD peripheral for high-throughput automotive and industrial networking, high-resolution PWM with 250 ps edge placement, and integrated op amps and 12-bit ADC for sensor interfacing. The functional-safety (FuSa) capability targets ASIL-B / SIL-2 designs by allowing the two cores to run independent diagnostics in lock-step or split tasks for cross-checking.
The device uses a 3.3 V CMOS process and offers 12-bit ADC with up to 3.5 MSPS sampling, multiple high-speed analog comparators, and a dedicated peripheral trigger generator that minimizes CPU load in tight control loops. The 80-pin TQFP provides 69 digital I/O plus analog channels, sufficient for multi-phase power stages or dual-axis drives without external GPIO expanders.
Typical applications include high-performance digital power supplies, server and telecom SMPS, wireless charging transmitters, drones and eVTOL motor controllers, automotive sensors and DC-DC converters, and multi-axis industrial servo drives. The dual-core architecture specifically accelerates applications that previously required two separate MCUs and a communication bus.
When designing with this part, ensure that the master and slave core firmware images are linked consistently and that the slave core is brought out of reset only after its program memory is loaded. Use the Microchip MPLAB X IDE with the XC-DSC compiler and the dsPIC33CH Motor Control or Digital Power plug-in modules for evaluation.

Applications typiques
DSPIC33CH128MP508T-I/PT convient pour 7 applications: High-Performance Digital Power Supply (SMPS), Multi-Axis Industrial Servo Drives, Wireless Power Transmitter Controller, Drone and eVTOL Motor Controllers, Automotive 48V Mild-Hybrid DC-DC Converters, Solar Inverter and MPPT Controller, Functional-Safety (FuSa) Appliance Controllers.
High-Performance Digital Power Supply (SMPS)
The DSPIC33CH128MP508T-I/PT fits server and telecom SMPS designs because the 200 MHz slave core executes 250 ps high-resolution PWM while the 180 MHz master core runs control algorithms and CAN-FD telemetry without interrupt contention. Its 152 KB Flash stores multi-loop state machines, adaptive digital compensators, and PMBus command sets. The 12-bit 3.5 MSPS ADC samples feedback currents and voltages synchronously to the PWM, while FuSa diagnostics enable ASIL-B power-converter certification.
Recommandé
Multi-Axis Industrial Servo Drives
The DSPIC33CH128MP508T-I/PT supports two-axis field-oriented control because each axis consumes independent PWM channels and ADC sample triggers and the dual cores can each handle one current-loop. The 80-pin TQFP exposes 69 digital I/O, enough for two quadrature encoders, two Hall-sensor inputs, and CAN-FD communication to a motion controller. The 200 MHz slave handles communication and fieldbus housekeeping, leaving the master core free to maintain 1 kHz current-loop update rates with deterministic latency.
Recommandé
Wireless Power Transmitter Controller
The DSPIC33CH128MP508T-I/PT drives wireless charging transmitter coils by generating precise phase-shifted PWM that synchronizes primary and secondary resonant networks. Its high-resolution 250 ps PWM edge placement enables foreign-object detection (FOD) by perturbing the operating frequency and observing Q-factor shifts. The slave core manages Qi or AirFuel protocol stacks, while the master core regulates inverter voltage, current, and temperature feedback. The 3.0-3.6 V supply suits USB-PD and 24 V industrial input rails via a downstream buck.
Recommandé
Drone and eVTOL Motor Controllers
The DSPIC33CH128MP508T-I/PT is well-suited to drone BLDC motor control because its 200 MHz slave core computes sensorless FOC at the high electrical speeds typical of multirotor motors (often >20,000 RPM). The master core maintains CAN-FD links to flight controllers while the slave drives 250 ps PWM commutation. The extended -40 C to +85 C industrial temperature range tolerates outdoor drone operating environments, and the 80-pin TQFP supports external current-sense amplifiers on dedicated analog channels.
Recommandé
Automotive 48V Mild-Hybrid DC-DC Converters
The DSPIC33CH128MP508T-I/PT can be used in 48V-to-12V automotive DC-DC converters because it supports CAN FD for communication with the vehicle's power-net management and offers 250 ps PWM for multi-phase synchronous rectification. The dual-core topology allows the master to run a 100 kHz control loop while the slave handles diagnostics and LIN/CAN messaging. Designers should select the AEC-Q100-qualified variant of the same family for production automotive deployments.
Recommandé
Solar Inverter and MPPT Controller
The DSPIC33CH128MP508T-I/PT targets string solar inverters because its 152 KB Flash stores adaptive MPPT algorithms (P&O, incremental conductance, model predictive) and its 12-bit ADC samples PV current and voltage synchronously to PWM. The slave core can drive a 4-line LCD or communicate via Modbus, while the master core maintains the inverter's grid-tie current loop. The 3.3 V supply simplifies auxiliary-power design in 600 V-class systems using a flyback bias rail.
Recommandé
Functional-Safety (FuSa) Appliance Controllers
The DSPIC33CH128MP508T-I/PT is a natural fit for functional-safety appliance control because its dual cores can run the same control loop twice and cross-check results, supporting ASIL-B / SIL-2 designs. The 80-pin TQFP provides enough I/O for motor drivers, sensor inputs, and safety relays. The slave core can host a safety test library, freeing the master core to focus on regulation. Use Microchip's Functional Safety Ready firmware framework to accelerate IEC 60730-1 or IEC 61508 certification.

Principaux différenciateurs
- Dual-core architecture with independent 200 MHz slave (vs DSPIC33CH128MP506-I/PT (same 80-pin TQFP))
- Higher 200 MHz slave-core frequency versus older dsPIC33 families (vs Single-core dsPIC33EP series (such as DSPIC30F6015-30I/PT, 30 MIPS))
- 80-pin TQFP with high-resolution 250 ps PWM and CAN FD (vs TMS320F28027 from Texas Instruments (38-pin, 60 MHz))
Notes de conception
Place 0.1 uF decoupling capacitors within 3 mm of every VDD/VSS pin pair on the 80-pin TQFP and add a single 10 uF bulk capacitor near the AVSS/AVDD analog supply pins. The dsPIC33CH analog supply is sensitive to high-frequency digital switching noise; route AVDD/AVSS traces away from PWM outputs and use a separate ground island on the inner PCB layer. Per Microchip application note AN1078, a ground split between digital and analog with a single-point tie under the device improves ADC SNR by 6-10 dB.
Critical pitfall: the slave core firmware image must be loaded by the master core at startup, otherwise the slave remains in reset. In MPLAB X IDE, ensure the project option 'Use Slave Program Memory' is enabled and the slave linker script partitions the shared Flash region correctly. Estimated: a slave firmware of 16 KB plus the master firmware of 80 KB fits within 152 KB total Flash with adequate margin. Failing to link both images produces a master core that hangs in SLAVE_RESET state.
Power sequencing note: VDD and AVDD must rise monotonically within 10 ms to ensure proper POR (power-on reset). If a separate analog LDO drives AVDD, enable it simultaneously with VDD to avoid latch-up. Estimated: with both cores running at full speed (180 + 200 MHz) and all peripherals active, IDD peaks near 95 mA. Design the 3.3 V LDO for 150 mA to maintain a 50% safety margin.
The 250 ps PWM edge placement generates fast slew rates that can cause ringing on the gate-drive traces. Per Microchip dsPIC33CH digital-power design guidelines, keep gate-drive traces shorter than 25 mm and add a 33 ohm source-termination resistor close to the PWM output pin. Estimated: a 50 mm unterminated trace produces -6 dB of overshoot at 100 MHz, which may exceed the gate-driver's absolute-maximum rating on some MOSFETs.
Estimated: at 180 MHz master + 200 MHz slave running dual FOC loops with full peripheral activity, the die dissipates approximately 0.7 W. The 80-pin TQFP has theta_JA near 50 C/W on a 2-layer PCB and 35 C/W on a 4-layer board with a continuous ground plane. For continuous 0.7 W operation in 70 C ambient, junction temperature reaches 105 C on the 2-layer board - within spec but with only 20 C margin to the 125 C industrial limit. Use a 4-layer board with a continuous copper pour under the TQFP thermal pad to maintain margin.
