PIC24EP64MC204-I/PT 개요
A PIC microcontroller (Microcontroller Unit, MCU) is a single-chip computer that integrates a CPU, memory (Flash for code, SRAM for data) and a rich set of peripherals such as timers, ADCs, communication interfaces, and PWM channels. PIC24E "enhanced" devices extend the classic PIC24 architecture with higher CPU throughput, more DMA channels and additional analog. The PIC24EP sub-family is further tuned for motor control and digital power, where deterministic PWM timing and fast ADC sampling close the current/torque loop on field-oriented control (FOC) algorithms.
Key features of the PIC24EP64MC204-I/PT include up to 70 MIPS operation from a 60 MHz peripheral clock, 64 KB self-write Flash, 8 KB SRAM, 35 I/O pins, an integrated 10/12-bit ADC, three op-amps usable for current sensing, four high-speed comparators with PWM fault inputs, and a 70 MHz PWM module with up to 8 outputs. The device operates from 3.0 V to 3.6 V, supports -40 °C to +85 °C industrial temperature range, and is RoHS compliant.
Typical applications include brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) field-oriented control, switched-mode power supplies (SMPS), uninterruptible power supplies (UPS), induction-cooking drivers, and HVAC compressor control. The combination of on-chip analog (op-amps + comparators) and the high-resolution PWM dramatically reduces the BOM for a complete sensorless or sensored FOC drive.
When designing with this device, verify the pinout against the datasheet diagram for your specific package (TQFP-44) and ensure that the keep-out area under the exposed thermal pad (if present) is correctly soldered for thermal performance. The PTG peripheral can offload simple tasks from the CPU and should be considered for deterministic timing in safety-critical loops.

일반적인 애플리케이션
PIC24EP64MC204-I/PT 적합 용도: 6 애플리케이션s: Brushless DC (BLDC) Motor Drive, PMSM Field-Oriented Control (FOC), Switched-Mode Power Supply (SMPS) / PFC, Industrial Servo / Robotic Drive, Uninterruptible Power Supply (UPS) / Inverter, HVAC Compressor / Induction Heating.
Brushless DC (BLDC) Motor Drive
The PIC24EP64MC204-I/PT is purpose-built for BLDC drives. Its MCPWM module delivers up to 8 complementary PWM channels at 70 MHz, three on-chip op-amps are sized for current sensing on the three phases, and four comparators provide hardware PWM fault inputs that shut the inverter down in microseconds. Combined with the 70 MIPS core, this part runs sensored or sensorless FOC on a single chip. The QEI module decodes quadrature encoder signals for precise rotor position. The 64 KB Flash / 8 KB SRAM pair is ample for typical state-space controllers and torque/speed PI loops, while the 3.0-3.6 V supply simplifies integration with 3.3 V gate drivers.
추천
PMSM Field-Oriented Control (FOC)
For permanent-magnet synchronous motor (PMSM) drives, the PIC24EP64MC204-I/PT provides the DSP-grade math throughput needed to run Park/Clarke transforms and PI current loops every PWM cycle. The 70 MIPS core pairs with 8 KB of zero-wait-state SRAM to keep loop latency predictable. The integrated QEI reads incremental encoders for rotor position, while MCPWM phase-shift and dead-band controls handle the inverter. Together, these peripherals let a single PIC24EP64MC204-I/PT replace a DSP+FPGA pair on a 1-5 kW PMSM drive, with a part-count and BOM reduction that pays back across small-batch production.
추천
Switched-Mode Power Supply (SMPS) / PFC
The 70 MIPS PIC24EP64MC204-I/PT plus its high-resolution MCPWM, fast comparators and PTG make it a strong digital controller for totem-pole PFC, LLC and phase-shifted full-bridge SMPS topologies. The PTG offloads fixed-timing tasks from the CPU and lets the firmware focus on the control law. The 12-bit ADC is fast enough for average-current-mode control at 100 kHz switching. Industrial-grade temperature range (-40 °C to +85 °C) plus 3.0-3.6 V supply let the part operate on the housekeeping rail directly. With 64 KB Flash the device fits CCM/DCM PFC, soft-start and brown-out firmware plus a full telemetry stack.
추천
Industrial Servo / Robotic Drive
The PIC24EP64MC204-I/PT targets industrial servo loops where 70 MIPS, 8 KB SRAM, on-chip op-amps and QEI are mandatory and the design needs to coexist on a 3.3 V supply. Inside the loop the device handles position/speed/PI control with PWM cycle deadlines enforced by hardware comparators for fault response in sub-microsecond time. The 35 I/O pins drive status LEDs, encoders, end-of-travel limits and isolated communications. Industrial -40 °C to +85 °C temperature rating makes it appropriate for factory-floor servo cabinets, and the 64 KB Flash fits a full CANopen or Modbus command set plus the FOC firmware.
추천
Uninterruptible Power Supply (UPS) / Inverter
For UPS and solar inverter control the PIC24EP64MC204-I/PT supplies the PWM channels for the H-bridge or three-phase inverter, the comparators for grid voltage/frequency monitoring and the ADC for input/output measurement. Its 3.0-3.6 V supply range and 70 MIPS performance to execute sinusoidal PWM, MPPT firmware and grid synchronization in real time. Industrial temperature rating plus robust QEI for rotary UPS and MCPWM for sine-wave synthesis make this part a one-chip controller for low- to mid-power UPS, replacing legacy 16-bit MCU+DSP pairs. 64 KB Flash fits MPPT, telemetry and protection firmware comfortably.
추천
HVAC Compressor / Induction Heating
For HVAC compressors, induction cooking and induction heating, the PIC24EP64MC204-I/PT provides the high-resolution PWM (up to 70 MHz) and fast comparators required for zero-voltage switching (ZVS) and zero-current switching (ZCS). The integrated PTG offloads deterministic safety timing so the firmware loop stays responsive to load changes. Industrial-grade -40 to +85 °C temperature rating plus a 3.3 V supply make it suitable for compressor inverter boards sitting behind a power module. 64 KB Flash holds compressor profile tables, fault logging and a comms stack (UART/LIN) for appliance networking.

설계 노트
Power the PIC24EP64MC204-I/PT from a low-noise 3.3 V LDO (e.g., MCP1700). The internal 1.2 V core regulator needs a 1 µF X7R VCAP capacitor on pin 13 (TQFP-44) placed within 1 cm. Avoid sharing the LDO with the inverter power rail — the comparators and op-amps are highly sensitive to VDD noise and will degrade PWM edge timing. Decouple VDD/VSS pairs at 100 nF X7R placed within 4 mm of each pair.
Estimated: at typical motor-control idle currents (CPU active, ADC sampling, MCPWM running), the part dissipates approximately 0.3 W. The 44-pin TQFP (PT) with a 100x100 mm² 2-layer board has θJA around 50 °C/W, yielding a junction-to-ambient temperature rise of ~15 °C at typical use. If the same board also hosts the inverter, locate the MCU away from the power stage and provide thermal vias under any exposed pad.
Keep the analog and digital ground planes separated under the MCU and join them at a single point near the device. This prevents switching noise from the PWM/IO drivers from coupling into the comparator reference and the op-amp inputs. The 100 µF to 4.7 µF bulk capacitor should be placed close to the AVDD/AVSS pair. Keep the crystal traces (OSC1/OSC2) short and surrounded by ground.
Do not skip the MCLR pull-up: the MCLR pin (pin 8) needs a 10 kΩ pull-up to VDD for normal operation, otherwise the MCU stays in reset. The ICSP™/ICD pins (PGD1/PGC1) must remain accessible for in-circuit programming — do not route them through switching devices. The PTG peripheral must be enabled via the CFG bit before use, otherwise the trigger sources are ignored silently.
Estimated: the on-chip op-amps have a unity-gain bandwidth around 10 MHz and are adequate for 100 kHz current sensing, but external fast op-amps (e.g., MCP6L02) may be required for higher switching frequencies. The QEI inputs are 5 V tolerant; route them close to the encoder to keep the trace under 2 m. Use twisted-pair cable to the encoder for noise immunity in industrial environments.
