DSPIC33CH128MP205-E/PT 概要
A Digital Signal Controller combines the deterministic interrupt response and ease-of-use of a microcontroller with the computational throughput of a DSP. Within the broader system hierarchy, a DSC sits below a generic MCU and provides hardware multiply-accumulate (MAC) instructions and single-cycle 40-bit accumulators, allowing it to close high-bandwidth control loops (digital power, field-oriented motor control) that an MCU cannot. The dsPIC33CH family's dual-core architecture extends this paradigm by partitioning software tasks: the master core runs the application framework and communications, while the slave core executes the time-critical control law in hardware-isolated memory, dramatically reducing jitter on the power conversion stage.
Key specifications include 100 MHz operation on both cores, 128 KB Flash (with up to 152 KB Flash per device family variant), 16 KB SRAM, four 16-bit timers, a configurable Logic Cell (CLC), four 12-bit DACs, and 39 selectable I/O sources. The integrated high-resolution PWM module features 1.04 ns duty cycle and 1.04 ns phase-shift granularity, which is essential for digital switch-mode power supplies (SMPS), totem-pole PFC, and LLC converters operating at hundreds of kHz.
Architecturally, the device uses a superset dsPIC33 DSC core with DSP-enhanced instruction set and a wide 16-bit data path. Dual-core communication is handled via a hardware Mailbox and a slave programmable interrupt controller. The AEC-Q100 qualification (denoted by the "E" in -E/PT) makes this variant suitable for automotive ECUs, sensor fusion, and traction control, while the -I/PT industrial variant targets factory automation and server PSUs.
Typical applications include digital switch-mode power supplies, LLC and PFC converters, brushless DC and PMSM motor control, sensorless FOC motor drives, wireless charging transmitters, server/DC-DC telemetry, and automotive LED headlamp drivers. The dual-core arrangement also suits safety-critical designs where the slave core can implement hardware-isolated diagnostics.
When designing with this device, validate that both cores' firmware images fit within 128 KB (master) + 32 KB (slave) and that all analog and PWM signals route to available pin functions. The PT package's 7x7 mm TQFP body supports standard reflow profiles and provides accessible debug via the 4-wire JTAG or 2-wire ICSP interface, which integrates natively with MPLAB X IDE and the MPLAB Code Configurator.

主な用途
DSPIC33CH128MP205-E/PT の用途: 6 件s: Digital Switch-Mode Power Supplies (SMPS) and Server PSU, Brushless DC / PMSM Motor Control (FOC), Wireless Charging / Inductive Power Transmitters, Automotive LED Headlamp Drivers and Adaptive Front-Lighting, Industrial Servo Drives and CNC Machine Tools, AEC-Q100 Sensor Fusion and Traction-Control ECUs.
Digital Switch-Mode Power Supplies (SMPS) and Server PSU
The DSPIC33CH128MP205-E/PT is purpose-built for digital switch-mode power supplies including LLC, full-bridge, active-clamp flyback, and totem-pole PFC topologies used in server, telecom, and industrial DC-DC converters. Its 1.04 ns high-resolution PWM edge placement lets the converter operate at 500 kHz+ switching frequency while maintaining tight regulation under dynamic loads, and the dual-core split means the slave core executes the average-current-mode control law with sub-microsecond deterministic jitter while the master handles PMBus telemetry, fault logging, and housekeeping. Paired with the MCP47CVB0x DAC and MCP330x ADC companions, the system achieves 1-2% output voltage accuracy across the -40C to +125C automotive/industrial range, well within the 80 Plus Titanium envelope for server PSUs.
おすすめ
Brushless DC / PMSM Motor Control (FOC)
For PMSM and BLDC motor drives, the DSPIC33CH128MP205-E/PT's dual-core architecture lets the slave core execute sensorless field-oriented control (FOC) with 10-20 kHz PWM and deterministic zero-crossing detection, while the master core manages CAN FD communications, application-layer logic, and safety diagnostics. The integrated high-resolution PWM module delivers 1.04 ns duty-cycle precision that translates directly to lower torque ripple and audible noise in e-bike traction motors, HVAC compressors, and small industrial servo drives; 12-bit 3.5 Msps ADCs sample phase currents synchronously to the PWM zero event for clean current loops. AEC-Q100 Grade 1 qualification is mandatory for automotive traction inverters and electric power steering applications.
おすすめ
Wireless Charging / Inductive Power Transmitters
Wireless charging transmitters for Qi, AirFuel, and proprietary in-cabin automotive systems use the DSPIC33CH128MP205-E/PT to handle foreign-object detection (FOD), coil current demodulation, and closed-loop power transfer regulation up to 15 W (Qi) and 50 W+ (AirFuel). The slave core runs the inverter control loop with single-cycle latency on every half-bridge switching event, eliminating the jitter that plagues single-core MCUs at low-cost Qi designs. The master core processes the Qi protocol state machine, manages PID-tuned input power limiting, and drives status LEDs. The AEC-Q100 Grade 1 qualification suits in-cabin automotive wireless charging pads in instrument panels and armrests, where temperatures can reach +105C under sunlight.
おすすめ
Automotive LED Headlamp Drivers and Adaptive Front-Lighting
Automotive LED headlamps from Tier-1 suppliers such as Hella, Marelli, and Valeo embed a DSPIC33CH128MP205-E/PT as the matrix-beam controller, where the slave core handles pixel-by-pixel current regulation at 200-400 Hz refresh, while the master executes the camera-input adaptive beam algorithm, communicates over CAN FD with the body controller, and manages thermal foldback via the integrated 12-bit ADC reading NTC thermistors. AEC-Q100 Grade 1 plus the -40C to +125C automotive temperature profile are mandatory. The 48-pin TQFP (PT) package fits behind the headlamp housing with adequate PCB thermal dissipation given the device's low 3.3V supply current.
おすすめ
Industrial Servo Drives and CNC Machine Tools
Industrial servo drive electronics serving 100 W to 5 kW brushless servo motors, CNC spindle drives, and robotic-arm joints use the DSPIC33CH128MP205-E/PT as the position/velocity/current-loop master. Dual-core partitioning lets the slave core execute the 8-32 kHz current loop while the master runs the slower position loop, EtherCAT/EtherNet/IP communications, and the safety-rated STO (Safe Torque Off) state machine. The high-resolution PWM supports the multi-MHz switching frequencies needed for low-inductance servomotors where torque bandwidth exceeds 1 kHz. Industrial temperature variant (-40C to +85C using I-grade equivalent) handles factory-floor enclosures without active cooling.
おすすめ
AEC-Q100 Sensor Fusion and Traction-Control ECUs
Automotive domain controllers for traction control, sensor fusion across IMU/GNSS/camera inputs, and supervisory vehicle dynamics benefit from the DSPIC33CH128MP205-E/PT's automotive qualification and real-time determinism. The dual-core split lets the slave core handle the 1 kHz sensor-fusion interrupt load with single-cycle latency while the master executes application-level decisions and CAN FD messaging with body, chassis, and ADAS controllers. The 48-pin TQFP package supports the temperature-cycling tests required by AEC-Q100 and is supported by Microchip's automotive PPAP documentation package. Designers using this part in ISO 26262 ASIL-B applications can leverage Microchip's functional-safety collateral.

設計ノート
The 48-pin TQFP (PT) 7x7 mm package has a theta_JA of approximately 41-46 C/W on a standard 2-layer PCB with minimum thermal vias (per JEDEC EIA/JESD51 test board). At full dual-core 100 MHz utilization the device typically draws 40-80 mA from 3.3 V (~0.13-0.26 W), which yields a junction temperature rise of only 6-12 C above ambient - no heatsink needed. For designs operating near the +125C automotive ceiling, however, the maximum ambient must be derated to stay below +150C Tj, i.e. 25-30 C of margin at maximum specification. Adding 4-9 thermal vias under the exposed die attach pad improves theta_JA by 20-30%.
Place decoupling capacitors as close to each VDD/VSS pair (pins 9/10, 26/25, 48/47) as physically possible: 100 nF X7R plus 10 uF X5R per pair minimum. Add a bulk 22-47 uF tantalum or polymer capacitor on the 3.3 V rail within 25 mm of the IC. Use a single-point ground star at the IC VSS pin to minimize digital switching noise coupling into the ADC ground reference; route analog and digital grounds separately and join them only at the IC. For high-resolution PWM outputs (1.04 ns edge placement), keep PWM traces short and matched in length when driving parallel FETs.
Common pitfalls include: (1) forgetting the slave core requires its own firmware image programmed separately from the master via PGEC2/PGED2 - DFU/live-update tools must route programming commands to the correct programming pins; (2) designing the master/slave memory map without partition checking - the linker script must explicitly constrain each core's firmware to its own flash window; (3) ignoring the high-resolution PWM's dead-time insertion - high-side and low-side FETs require configurable dead-time to prevent shoot-through; (4) using a 3.3 V supply that droops below 3.0 V under heavy transient load, which causes brownout reset; (5) omitting the configuration bits (FSEC, FOSC, etc.) in source code - always set them via MPLAB X IDE configuration registers.
