PIC24EP128MC202-E/SP 概要
A 16-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals on one die, executing instructions on 16-bit-wide data paths to balance code density, deterministic interrupt response, and arithmetic performance for embedded control. PIC24EP parts sit within the broader PIC microcontroller taxonomy (PIC10/12/16/18/24/32) and specifically the PIC24E sub-family, which adds enhanced DSP instructions, dual read-port Flash, and high-speed PWM peripherals that the 'MC' (Motor Control) variants further optimize.
Key differentiating features include a 12-bit ADC with up to 500 ksps conversion rate, dual 16-bit/32-bit op-amps accessible to the ADC front-end, high-resolution PWM (typical 7.14 ns resolution at 70 MIPS) for field-oriented control (FOC) loops, four 32-bit timer/capture modules, two UART, two SPI, and one I2C peripheral, plus a 32-bit CRC engine. The 'MC' peripheral set was specifically tuned for sensorless and sensored BLDC, PMSM, ACIM, and stepper motor control, including hardware fault inputs and PWM shutdown logic.
Architecturally, the PIC24EP uses a Harvard-style modified RISC core with a 24-bit instruction word and dual-port Flash allowing live reads while executing, accelerating firmware hot paths in motor ISR loops. The high-speed ADC-to-PWM datapath, with the op-amps pre-conditioning current shunt signals, lets a single MCU close current, torque, and velocity loops at 20-50 kHz without an external DSP.
Typical applications include brushless DC (BLDC) and permanent-magnet synchronous (PMSM) motor controllers for appliance pumps and fans, automotive body and HVAC actuators, industrial servo drives, drone ESCs, robotic joints, and field-oriented control drives for low-voltage battery-powered tools. Designers also deploy this part in power-conversion front-ends that require high-resolution PWM plus the on-chip op-amps for current sensing.
When designing with the PIC24EP128MC202-E/SP, allocate the op-amp outputs to dedicated ADC channels to minimize latency, and use the on-chip high-resolution PWM for low-speed torque ripple reduction. Be aware that the 28-SPDIP package imposes a larger PCB footprint than equivalent QFN parts, so confirm mechanical fit before selecting this packaging option.

BLDC / PMSM Motor Control (FOC)
The PIC24EP128MC202-E/SP is purpose-built for sensorless and sensored BLDC and PMSM motor control. Its 60 MIPS PIC24E core, dual internal 32 MHz op-amps for current-shunt amplification, 12-bit 500 ksps ADC, and six high-resolution 7.14 ns PWM channels let a single MCU execute complete field-oriented control loops at 20-50 kHz without an external DSP. Microchip's AN1078 sensorless FOC and AN1160 sensored BLDC reference designs are validated on this exact silicon, providing proven firmware for pumps, fans, and small traction drives.
おすすめ
Automotive Body Electronics Actuators
AEC-Q100 qualification and -40C to +125C operation make the PIC24EP128MC202-E/SP a strong fit for automotive body-electronics motor-control modules such as HVAC flap actuators, headlamp leveling, seat ventilation fans, and door-zone LIN slaves. The high-resolution PWM enables silent torque ripple control, while the op-amp front-end directly digitizes current-shunt signals without external amplifiers. The 128 KB Flash comfortably hosts AUTOSAR-friendly motor-control libraries plus a UDS/J1939 bootloader.
おすすめ
Home Appliance Pumps and Compressors
Variable-speed pumps and compressors in dishwashers, washing machines, and refrigerators use the PIC24EP128MC202-E/SP for sinusoidal FOC of PMSM or BLDC motors. The 60 MIPS throughput handles the FOC math, plus space-vector modulation and a low-speed sensorless observer, while the AEC-Q100 grade extends product life into harsh under-cabinet thermal environments. The 128 KB Flash accommodates full sensorless startup curves and OEM diagnostic routines.
おすすめ
Industrial Servo and Stepper Drives
Low-voltage 24-48 V industrial servo and stepper drives benefit from the PIC24EP128MC202-E/SP's deterministic PIC24E interrupt structure, fast 60 MIPS core, and HR-PWM. Closed-loop stepper control with on-the-fly microstepping and stall-detection algorithms fit comfortably in 128 KB Flash. The dual op-amps directly digitize phase-current shunts, removing 2-4 external amplifiers per axis and shrinking the BOM.
おすすめ
Drone / UAV Electronic Speed Controllers
Lightweight quadcopter and drone ESCs use the PIC24EP128MC202-E/SP to run 50 kHz+ FOC loops on multi-pole BLDC outrunner motors. The high-resolution 7.14 ns PWM keeps commutation timing jitter low enough to suppress audible motor noise, and the 60 MIPS throughput supports DSHOT/Oneshot protocol decoding alongside the motor-control ISR. The 28-SPDIP package simplifies hand-soldered prototype ESCs in the lab.
おすすめ
Battery-Powered Cordless Power Tools
Cordless drills, impact drivers, and 18-48 V garden tools use the PIC24EP128MC202-E/SP to drive sensored BLDC motors with active freewheel and back-EMF braking. The 12-bit ADC and op-amps capture pack current and motor BEMF for overload protection and motor-temperature estimation. The 128 KB Flash stores multiple motor calibration profiles for low-speed and high-speed gears, and AEC-Q100 helps meet demanding vibration and thermal-stress profiles.

- High-resolution PWM (7.14 ns resolution) for low-speed torque ripple control （vs PIC24EP128GP202-I/SP)

設計ノート
Place the 10 uF + 0.1 uF decoupling pair within 5 mm of VDD (pin 20) and AVDD (pin 6), with a wide ground return to VSS/AVSS. Keep the analog AVSS trace short and route it back to the power supply star-ground to avoid digital switching noise corrupting the ADC/op-amp reference. The op-amp outputs (RC1/RC3) must connect to dedicated ADC channels and not be shared with digital loads.
Do not program the device above 3.6 V VDD or below 3.0 V - the Flash and ADC specifications are only guaranteed in this window. The PGEC1/PGED1 pins (RB6/RB7) are used for in-circuit serial programming; do not place pull-ups that exceed 4.7 kOhm or ICD3 will fail to drive the lines. Op-amp input pairs must be configured for the current-shunt polarity or FOC current sign will be reversed.
Route the high-speed PWM traces (PWM1H/L through PWM3H/L) as differential pairs where possible to minimize ringing. Keep switching traces away from the analog op-amp inputs by at least 3 mm or surround the analog region with a ground moat. Place the external crystal or resonator close to RA6/RA7 with short traces; the -E grade at +125C requires a crystal rated to +125C for stability.
The HR-PWM resolution (7.14 ns at 70 MIPS) requires a clean 7.37 MHz oscillator source; an Fcy of exactly 70 MIPS is needed to hit the documented 7.14 ns edge placement. If a 10 MHz crystal is used, configure the PLL to derive Fcy = 60 MIPS for the documented 8.33 ns HR-PWM step; mismatched Fcy will quantize the duty cycle and degrade low-speed torque ripple performance.
