PIC24EP128MC204-E/PT 概要
A Digital Signal Controller is a hybrid between a microcontroller and a DSP, offering deterministic real-time control plus efficient mathematical processing. In the system hierarchy the PIC24EP128MC204 sits under DSC -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. The 70 MIPS core, high-resolution PWM (1.04 ns PWM resolution with 8 output pairs) and on-chip op-amps make the part especially suited to closed-loop field-oriented control of PMSM, BLDC and AC induction motors.
Key features of the PIC24EP128MC204-E/PT include the Motor Control PWM (8 outputs / 4 pairs), a 10-bit ADC with up to 9 channels and 1.1 Msps conversion rate, two on-chip operational amplifiers for current sensing, a Quadrature Encoder Interface (QEI), a Peripheral Trigger Generator (PTG), and four general-purpose 16-bit timers. The device also exposes two UART, two SPI, and one I2C communication peripherals, plus an enhanced Parallel Master Port (PMP/EPSP) for external memory or graphics expansion.
Architecturally the PIC24EP family uses a 16-bit modified Harvard CPU with a 24-bit instruction word and 16-bit data path, allowing single-cycle MAC operations and deterministic interrupt latency. The peripheral trigger generator permits time-base synchronization between PWM, ADC and DMA without CPU intervention, reducing software jitter in torque loops. Dual-rail analog capability (separate AVDD/AVSS) improves ADC noise immunity in noisy inverter switching environments.
Typical applications include sensorless and sensored BLDC motor drives, HVAC compressor control, e-bike and e-scooter traction inverters, industrial servo drives, and automotive auxiliary pumps. The AEC-Q100 grade and extended temperature range make it directly applicable to under-the-hood automotive motor modules and 48 V mild-hybrid subsystems.
When designing with this part, remember the PIC24EP128MC204-E/PT requires a 3.3 V regulated supply and a 4x PLL multiplier plus a postscaler to reach the 70 MIPS throughput; clock configuration must be set in the device Configuration registers before peripheral use. Always de-bounce the motor fault inputs through hardware before connecting them to the PWM fault pins.

主な用途
PIC24EP128MC204-E/PT の用途: 7 件s: Sensored BLDC Motor Drive, Automotive HVAC Compressor Control, Industrial Servo Drive, E-bike / E-scooter Traction Inverter, Auxiliary Automotive Pumps and Fans, Sensorless PMSM Compressor Drive, Solar-Powered Water Pump Controller.
Sensored BLDC Motor Drive
The PIC24EP128MC204-E/PT is well-suited to sensored BLDC motor drives thanks to its 8-output / 4-pair Motor Control PWM with 1.04 ns resolution, two integrated op-amps for current shunt conditioning, and a dedicated Quadrature Encoder Interface for rotor position feedback. The 70 MIPS CPU executes Field-Oriented Control (FOC) at 20 kHz switching frequency with sufficient headroom for sensorless observer algorithms. AEC-Q100 qualification permits deployment in automotive water pumps, oil pumps and HVAC blowers. The device shares the 44-pin TQFP package with its industrial sibling PIC24EP128MC204-I/PT, simplifying BOM qualification across consumer and automotive SKUs.
おすすめ
Automotive HVAC Compressor Control
For automotive HVAC compressor inverters, the PIC24EP128MC204-E/PT brings AEC-Q100 Grade 1 qualification, an extended -40 C to +125 C operating range, and the deterministic 16-bit DSC core required for sinusoidal FOC at switching frequencies up to 20 kHz. The on-chip Peripheral Trigger Generator synchronizes ADC sampling to PWM edges, eliminating software jitter in torque-loop calculations. Two op-amps feed the dual-shunt current sensing network, while the DMA engine offloads encoder and ADC traffic so the CPU can run the speed PI loop at fixed cadence. Compared to a Cortex-M0 design, the DSC architecture delivers FOC in a single CPU cycle, reducing interrupt latency.
おすすめ
Industrial Servo Drive
In a closed-loop industrial servo, the PIC24EP128MC204-E/PT uses its 4-pair PWM to drive the three-phase inverter at 16 kHz or higher, with dead-time control implemented in hardware to prevent shoot-through. The Quadrature Encoder Interface decodes an incremental encoder at up to 10 Mcps to maintain rotor position accuracy, while the on-chip op-amps condition the current-shunt signals to feed the 1.1 Msps ADC. The 16 KB SRAM holds two FOC state-machine contexts plus a control-logic buffer, allowing developers to integrate Ethernet or CANopen firmware without external memory. The 70 MIPS throughput ensures the position loop runs at 4 kHz.
おすすめ
E-bike / E-scooter Traction Inverter
Light electric vehicles such as e-bikes and e-scooters benefit from the PIC24EP128MC204-E/PT's small 44-pin TQFP footprint, low 3.3 V supply and integrated motor-control peripherals, which eliminate the need for an external DSP. The 70 MIPS DSC runs trapezoidal or sinusoidal commutation on 36 V to 48 V battery packs, while the 1.04 ns PWM resolution enables silent low-speed torque delivery - a key differentiator versus discrete 8-bit MCU designs. Two UART interfaces support a throttle display and Bluetooth telemetry module simultaneously. The -E temperature grade permits operation in hot motor housings and direct sun on summer days.
おすすめ
Auxiliary Automotive Pumps and Fans
Electric water pumps, oil pumps and cooling fans in 12 V/48 V mild-hybrid vehicles use the PIC24EP128MC204-E/PT as a single-chip motor controller. The hardware QEI accepts Hall-effect or quadrature encoder signals without external counters, the dual on-chip op-amps condition low-side current-shunt measurements, and the 8-channel DMA offloads ADC and PWM updates to maximize CPU availability for CAN-FD comms. AEC-Q100 Grade 1 qualification eliminates the need for additional qualification cycles on the customer side. The 128 KB Flash holds both FOC firmware and LIN/CAN stack with margin for OBD-II diagnostics.
おすすめ
Sensorless PMSM Compressor Drive
Refrigerant compressors in white goods and light-commercial HVAC systems run on sensorless PMSM control loops that demand high CPU throughput and precise PWM timing. The PIC24EP128MC204-E/PT delivers 70 MIPS, hardware PWM with 1.04 ns edge placement, and a Peripheral Trigger Generator that synchronizes ADC sampling to the PWM center for maximum DC-bus noise rejection. The integrated op-amps allow single-shunt current reconstruction that lowers BOM cost, while the 128 KB Flash stores sensorless observer code plus compressor-specific protection routines (over-current, under-voltage, locked rotor). The -E grade handles the elevated ambient near the compressor shell.
おすすめ
Solar-Powered Water Pump Controller
Off-grid solar water pumps benefit from the PIC24EP128MC204-E/PT's 3.0-3.6 V supply tolerance that matches 12 V lead-acid or lithium battery banks with a simple buck regulator, plus the AEC-Q100 grade that ensures reliability in harsh field enclosures. The Quadrature Encoder Interface accepts flow-meter pulses for closed-loop flow regulation, while the 8-channel DMA offloads ADC scans of solar panel voltage, current and tank level sensors. Two UART ports expose an RS-485 Modbus interface for remote telemetry. Compared to discrete 8-bit MCU designs, the DSC core runs MPPT at 32 kHz with full-resolution ADC sampling.

設計ノート
Estimated: the PIC24EP128MC204-E/PT draws approximately 60 mA at 70 MIPS with all peripherals active (3.3 V supply). Decouple VDD with a 10 uF bulk + 0.1 uF ceramic pair on each VDD/VSS pair (pins 8/9 and 28/29). A separate 10 uH + 10 uF pi-filter on AVDD/AVSS reduces ADC sampling noise by 6-10 dB in switching-converter environments. Add a ferrite bead in series with the analog rail if the digital 3.3 V is shared with a gate driver.
Place the 44-pin TQFP on a 0.8 mm pitch and route PWM traces as differential pairs with 8 mil gap to reduce switching-edge ringing. Keep shunt resistors within 5 mm of the op-amp inputs to minimize noise pickup, and place the bootstrap capacitors for the gate driver as close as possible to the high-side driver pins. Use a 4-layer PCB with a continuous ground plane under the MCU; this typically reduces radiated emissions by 10-15 dB at the 70 MHz CPU clock harmonic.
Do not leave the MCLR pin floating - it must be pulled high through a 10 kOhm resistor to VDD, with a 100 nF capacitor to ground for noise debouncing. Failure to configure the FOSC, FPLL and FICD Configuration bits before enabling the PLL will leave the CPU at 8 MHz default and will not achieve the 70 MIPS throughput. Always program the JTAG off (ICS bits) before sealing the device in production to prevent accidental JTAG access and to free PGC1/PGD1 for GPIO.
Estimated: at 70 MIPS CPU load and typical I/O toggling, the PIC24EP128MC204-E/PT dissipates roughly 200 mW - well within the 44-pin TQFP thermal envelope (theta_JA around 60 C/W). No external heatsink is required. However, in sealed enclosures at 85 C ambient, the silicon die may approach 100 C; derate by 10-15% in firmware (reduce CPU clock to 60 MIPS) to keep junction temperature below the 125 C AEC-Q100 limit.
