PIC24EP64MC202-I/SS 概要
An MCU (microcontroller unit) is a single-chip computer integrating a CPU core, program memory (typically Flash), data memory (SRAM), and a rich set of on-chip peripherals such as timers, ADC, communication controllers, and GPIO. The PIC24EP family extends this concept into the digital-signal-control (DSC) segment with a 16-bit modified Harvard architecture and a single-cycle MAC engine, bridging 8-bit PIC microcontrollers and 32-bit ARM Cortex parts. Within Microchip's taxonomy, the dsPIC33/PIC24EP "MC" family is the motor-control-optimized derivative of the PIC24EP DSC line, distinguished by high-resolution PWM, fast ADC, QEI for shaft feedback, and analog comparators that protect the power stage.
Key features include three pairs of complementary PWM outputs (6 PWM channels) with 1.04 ns resolution, a 10-bit ADC with up to 500 ksps conversion, two on-chip operational amplifiers usable as current-sense buffers, three high-speed comparators for cycle-by-cycle overcurrent protection, a Quadrature Encoder Interface (QEI), and a Peripheral Trigger Generator (PTG). The device operates from 3.0 V to 3.6 V across an industrial temperature range of -40 C to +85 C and supports USB, I2C, SPI, and UART interfaces for supervisory or HMI connectivity.
Typical applications include sensorless and sensored BLDC/PMSM motor drives (fans, pumps, drones, e-bikes), appliance compressors, small industrial servo drives, robotics, and power tools. Two op-amps on-die directly sense shunt resistors in a three-phase inverter, eliminating external amplifiers and shrinking BOM. The high-resolution PWM and 10-bit ADC in 1 MSPS sampling capability simplify current-loop tuning.
When designing with this part, place decoupling capacitors within 3 mm of each VDD/VSS pin pair and route the analog AVdd/AVss pair with a separate ground island tied to digital ground at a single point. Program Flash via ICSP or the device's JTAG boundary-scan interface using MPLAB X IDE and the XC16 compiler.

主な用途
PIC24EP64MC202-I/SS の用途: 6 件s: BLDC / PMSM Motor Control, Sensorless Fan / Pump Drives, Appliance Compressor Drives, Power Tools and Cordless Drills, Small Industrial Servo Drives, Drone and Robotics ESC.
BLDC / PMSM Motor Control
The PIC24EP64MC202-I/SS is purpose-built for 3-phase BLDC and PMSM motor control, where its 6-channel high-resolution PWM (1.04 ns edge resolution) drives the inverter half-bridges and the on-chip 2 op-amps buffer shunt-resistor current feedback into the 10-bit ADC for the FOC current loop. Combined with the QEI module for shaft-position sensing and 70 MIPS CPU performance for Park/Clarke/PI computations, the part supports field-oriented control loops running at 20-50 kHz in 28-SSOP. Two on-chip op-amps replace external amplifiers that would otherwise inflate BOM cost in a 3-phase inverter.
おすすめ
Sensorless Fan / Pump Drives
The PIC24EP64MC202-I/SS's 64 KB Flash and 8 KB SRAM are sufficient for sensorless back-EMF or BEMF-flux observer algorithms driving small BLDC fans and pumps where cost dominates. The 3 high-speed comparators handle zero-cross detection of the floating phase voltage, while the integrated op-amps amplify low-side shunt signals for current-limit protection. Running at 70 MIPS the controller can sustain a 4-8 kHz BEMF-zero-cross estimation loop alongside the main commutation loop, all within the compact 28-SSOP footprint ideal for space-constrained consumer and appliance designs.
おすすめ
Appliance Compressor Drives
Refrigerator and air-conditioner compressors using variable-speed BLDC or PMSM motors benefit from the PIC24EP64MC202-I/SS's combination of PWM fault shutdown, hardware overcurrent comparators, and integrated analog front end. The 6 PWM outputs with dead-time insertion drive a 3-phase IGBT or MOSFET inverter directly, while the three comparators provide independent hardware protection for cycle-by-cycle current limiting - critical for compressor start-up inrush conditions. Industrial -40 C to +85 C temperature range supports the operating envelope of household and light-commercial appliances.
おすすめ
Power Tools and Cordless Drills
Brushless corded and battery-powered tools (drills, impact drivers, saws) leverage the PIC24EP64MC202-I/SS for compact high-speed motor control with battery monitoring. The 16-bit CPU runs sensorless or sensored FOC at 50+ kHz current loops, while on-chip op-amps directly sense phase currents from low-side shunts - eliminating external amplifier stages needed by less-integrated MCUs. UART/I2C peripherals connect to battery management ICs, and the wide industrial temperature range survives the harsh thermal environment of motor housings during high-torque operation.
おすすめ
Small Industrial Servo Drives
Sub-100 W industrial servo applications (CNC feed axes, robotics joints, conveyor drives) use the PIC24EP64MC202-I/SS to combine position, velocity, and current closed-loop control in one chip. The QEI module decodes incremental encoder A/B/Index signals up to several MHz, while the 70 MIPS CPU runs the cascaded PID control loops with sub-millisecond cycle times. USB connectivity enables direct host PC commissioning without an external interface IC, and the SSOP-28 form factor supports compact PCB integration into modular servo amplifier designs.
おすすめ
Drone and Robotics ESC
Electronic speed controllers (ESC) for small drones and hobby robotics use the PIC24EP64MC202-I/SS for high-frequency, low-latency motor commutation. The 1.04 ns PWM edge resolution supports 24 kHz+ PWM frequencies needed for low-inductance outrunner motors, while the comparator-based hardware current limit protects against prop-stall overcurrent events. 70 MIPS performance handles fast throttle-to-PWM mapping with minimal input lag, and the small SSOP-28 footprint suits the cramped ESC PCB inside a quadcopter arm.

設計ノート
Estimated: at 60 MHz CPU + active PWM + ADC + USB, VDD 3.3 V, the PIC24EP64MC202-I/SS draws approximately 25-35 mA core current (per Microchip datasheet DS70000657G typical curves). Place a 10 uF bulk + 0.1 uF decoupling capacitor within 3 mm of each VDD/VSS pin pair. Use a separate ferrite-bead-isolated AVDD rail for the analog supply to keep switching noise out of ADC and comparator references.
Estimated layout recommendation: route the analog AVSS/AVDD pair as a star ground tied to the digital VSS at a single point near the IC, keep PWM traces short and matched to within 5 mm to avoid shoot-through skew, and place the op-amp feedback components as close as possible to OA1IN-/OA1OUT. The exposed thermal pad (where present) must be soldered to a copper pour for thermal dissipation.
A common mistake is leaving the unused USB transceiver pins (RCV, VMIO, VP) floating when USB is not used. Microchip's errata recommends tying them to ground via 10 k resistors if USB is disabled, otherwise the unused analog inputs can inject noise into adjacent ADC channels. Also, when migrating from PIC24EP64MC202 to PIC24EP32MC202, verify that the reduced 32 KB Flash does not exceed application firmware size; the linker map file should show at least 10% margin.
