PIC24EP32MC204-H/PT 概要
A 16-bit MCU (microcontroller unit) is a single-chip computer built around a 16-bit data path, instruction word, and ALU. Within Microchip's taxonomy, PIC24E devices sit between the legacy PIC16/PIC18 8-bit families and the 32-bit PIC32 parts, offering higher throughput than 8-bit cores while retaining the deterministic interrupt model familiar to PIC developers. The PIC24E family in particular is positioned for digital-signal-control applications such as motor control, power conversion, and switching power-supply regulation, where 70 MIPS execution, hardware PWM and on-chip analog make single-chip solutions practical.
Key features of the PIC24EP32MC204-H/PT include a 70 MIPS 16-bit dsPIC33/PIC24E core, 32 KB of Flash program memory, 4 KB of SRAM, four on-chip operational amplifiers for current sensing, dedicated high-resolution PWM outputs suitable for sinusoidal motor commutation, and Motor Control PWM peripherals with complementary outputs and dead-time control. The integrated op-amps allow direct interface to low-side current-sense resistors, eliminating external amplifier stages and saving board area. The part also includes multiple UART/SPI/I2C interfaces, a 12-bit ADC, and configurable I/O for encoder or Hall-sensor feedback.
Architecturally, the PIC24E core uses a modified Harvard structure with separate program and data buses, hardware MAC/divide, and zero-overhead looping. The internal oscillator and PLL provide flexible clocking from 8 MHz crystals or external sources, and the device supports 5V-tolerant I/O on selected pins. The result is a deterministic, interrupt-friendly MCU tailored for time-critical closed-loop control loops running at kHz to tens-of-kHz update rates.
Typical applications for the PIC24EP32MC204-H/PT include BLDC and PMSM motor drives in industrial automation, field-oriented control (FOC) of permanent-magnet synchronous motors, automotive HVAC blower and pump controllers, robotic actuators, ceiling-fan and appliance motor control, and low-voltage battery-powered tools. Its integrated op-amps simplify three-phase current sensing and the high-resolution PWM enables silent sinusoidal drive.
When designing with this device, ensure that the high-temperature grade matches your application's worst-case ambient. The PT (TQFP-44) package has moderate thermal headroom; for high-current drive stages, isolate the analog ground from the noisy power ground using Microchip's recommended star-ground layout. Decouple VDD/VSS pairs with 100 nF ceramics as close to the pins as possible.

主な用途
PIC24EP32MC204-H/PT の用途: 6 件s: BLDC / PMSM Motor Drive (FOC), Automotive HVAC Blower / Pump Controller, Industrial Servo / Stepper Control, Ceiling Fan / Appliance Motor Control, Battery-Powered Power Tool Drive, Robotic Actuator / Drone ESC.
BLDC / PMSM Motor Drive (FOC)
The PIC24EP32MC204-H/PT's 70 MIPS core, dedicated motor-control PWM with up to 16.5 ns high-resolution edge placement, and four on-chip op-amps for low-side current sensing make it a single-chip FOC controller for BLDC and PMSM motors. In a typical sensorless FOC loop, the ADC samples phase currents every 10-20 us, the dsPIC33/PIC24E core executes Park/Clarke transforms, and the PWM peripheral outputs three-phase sinusoidal duty cycles. Compared with discrete MCU + external op-amp designs, the integrated op-amps cut BOM count by 4 parts and the H grade +150C rating enables under-hood automotive placement.
おすすめ
Automotive HVAC Blower / Pump Controller
With AEC-Q100 qualification and the -40C to +150C H temperature grade, the PIC24EP32MC204-H/PT is rated for under-hood automotive HVAC blower and coolant-pump motor control. The on-chip op-amps interface directly to low-side shunt resistors in the inverter stage, while the high-resolution PWM delivers quiet sinusoidal commutation required for cabin-noise-sensitive applications. The integrated CAN/UART peripherals (where supported by the device variant) allow integration with the vehicle CAN bus for speed command and telemetry.
おすすめ
Industrial Servo / Stepper Control
For industrial servo and stepper drives the PIC24EP32MC204-H/PT provides the deterministic interrupt latency and 70 MIPS throughput needed for closed-loop current/torque control loops running at 20-50 kHz update rates. The 12-bit ADC captures feedback from current shunts, and the PWM module generates the switching waveforms with programmable dead-time to prevent shoot-through in the H-bridge. The -40C to +150C H grade supports factory-floor ambient conditions with margin.
おすすめ
Ceiling Fan / Appliance Motor Control
Consumer ceiling fans and white-goods appliances use single-chip MCU + inverter solutions to deliver silent BLDC motor drive, remote-control speed adjustment, and energy-efficiency compliance. The PIC24EP32MC204-H/PT delivers sinusoidal PWM to the gate driver, integrates the current-sense op-amps, and runs the state-machine + UART IR receiver code within 32 KB Flash. Compared with discrete 8-bit MCU solutions, the 16-bit performance cuts switching losses and audible torque ripple.
おすすめ
Battery-Powered Power Tool Drive
Cordless drills, saws and outdoor tools run on 18-36 V Li-ion battery packs and need efficient, low-loss BLDC motor control for runtime and thermal reasons. The PIC24EP32MC204-H/PT runs sensorless FOC on a 70 MIPS core at 3.3 V from a buck converter, and its on-chip op-amps sense phase currents without external amplifiers. The H temperature grade tolerates elevated internal tool temperatures during sustained high-current operation.
おすすめ
Robotic Actuator / Drone ESC
Lightweight robotic actuators and small UAV electronic speed controllers (ESCs) require high PWM resolution and fast current loops in a small package. The PIC24EP32MC204-H/PT in TQFP-44 (10x10 mm) provides 70 MIPS control plus 16.5 ns PWM edge resolution and four on-chip op-amps for current telemetry, all in a footprint compatible with the 44-pin TQFP drop-in family. The H grade allows operation in elevated-temperature ESC housings.

設計ノート
The TQFP-44 (PT) package has a moderate theta_JA in the range of 40-50 C/W on a standard 4-layer JEDEC test PCB. The 'H' grade junction-temperature limit is +150C, so at 85C ambient the device can dissipate approximately 1.3-1.6 W before derating. For high-PWM-density applications with sustained switching, ensure sufficient copper pour under the exposed thermal footprint and route motor-drive return currents on inner layers away from the analog ground pour.
Per the Microchip datasheet, place a 100 nF decoupling capacitor as close as possible to every VDD/VSS pin pair, plus a bulk 10 uF ceramic near the package to handle PWM-edge inrush on the digital supply. Route analog VREF+/VREF- traces with ground shielding, and use a star-ground topology at the AGND/VSS boundary to keep motor-switching noise out of the ADC sampling window. AVSS must be tied to VSS at exactly one point near the IC.
Estimated: the four on-chip op-amps have a limited input common-mode range that must be checked against the actual shunt-resistor common-mode voltage (typically near the negative rail for low-side sensing). If the shunt voltage exceeds the op-amp input range, add an external resistor divider or use high-side sensing. Also, the high-resolution PWM mode (16.5 ns edge) requires specific peripheral configuration; users should NOT assume the standard 8.32 ns edge resolution applies without enabling the HRPWM module in firmware.
Per Microchip application notes, place the MCU on the same PCB side as the gate driver to minimize gate-loop inductance, and keep the OSC1/OSC2 traces short and surrounded by a ground guard ring. For three-phase BLDC drive layouts, mirror the phase-A/B/C current-shunt traces so that switching transients cancel at the op-amp input pins; this preserves ADC accuracy during the PWM edge event.
