PIC24EP128MC202-I/MM 개요
A 16-bit microcontroller (MCU) is an integrated circuit containing a CPU, program memory (Flash), data memory (SRAM), and on-chip peripherals on a single die. Within the broader taxonomy, the PIC24EP belongs to the digital signal controller (DSC) class - devices that combine a microcontroller architecture with DSP-grade instructions for real-time control loops. PIC24EP sits in the high-performance tier of Microchip's PIC24 family, above baseline PIC24F parts, and offers dedicated motor-control peripherals including up to 6 PWM channels with multiple modes and on-chip op-amps for current sensing.
Key features include 70 MIPS CPU speed, 128 KB Flash (43K x 24 words), 16 KB SRAM, integrated high-speed PWM with up to 6 channels, multiple on-chip operational amplifiers for current sensing, advanced analog (12-bit ADC), and a rich set of communication peripherals. The MM package pinout supports field-oriented control (FOC) loops with minimal external components. Integrated op-amps reduce BOM by eliminating external current-sense amplifiers in most brushless DC motor designs.
Typical applications include BLDC/PMSM motor drives, field-oriented control inverters, industrial fans and pumps, automotive HVAC actuators, and high-precision servo control. The high PWM resolution and on-chip analog front-end make it well suited to sensorless and sensored motor control algorithms.
When designing with this MCU, ensure the 28-QFN exposed pad is properly soldered for thermal dissipation; this device is rated for the -40 C to +85 C industrial temperature range. Memory-mapped peripherals and a deterministic interrupt controller allow consistent loop times critical for smooth torque and speed control.

일반적인 애플리케이션
PIC24EP128MC202-I/MM 적합 용도: 6 애플리케이션s: BLDC/PMSM Motor Control, Field-Oriented Control (FOC) Inverters, Industrial Fans and Pumps, Automotive HVAC Actuators, Precision Servo Control, Sensorless BLDC Drivers.
BLDC/PMSM Motor Control
The PIC24EP128MC202-I/MM is purpose-built for brushless DC and permanent magnet synchronous motor control, integrating high-resolution PWM, on-chip operational amplifiers, and a 12-bit ADC. Its 70 MIPS CPU executes field-oriented control (FOC) loops within the typical 10-50 us cycle time required for smooth commutation at 30,000 RPM. The integrated op-amps eliminate external current-sense amplifiers, reducing BOM cost and PCB area. This makes it ideal for compact BLDC drivers in fans, pumps, drones, and e-mobility. Designers can implement sensorless back-EMF or sensored FOC with deterministic interrupt latency from the peripheral engine.

Field-Oriented Control (FOC) Inverters
For FOC inverters driving industrial servo motors, the PIC24EP128MC202-I/MM delivers the CPU throughput and PWM resolution needed for sinusoidal commutation. Its 6 PWM channels support complementary high-side/low-side drive with programmable dead-time insertion, while on-chip op-amps handle shunt-based phase-current sensing without external amplifiers. The 70 MIPS core runs the Park/Clarke transforms, PI controllers, and SVPWM generator within tight loop times. The 28-QFP exposed pad supports thermal dissipation for full-load industrial operation. This combination enables single-MCU inverter designs up to several hundred watts.
추천
Industrial Fans and Pumps
Variable-speed industrial fans and pumps benefit from the PIC24EP128MC202-I/MM's BLDC control capability and low BOM integration. The on-chip op-amps interface directly to low-side shunt resistors, while the high-resolution PWM delivers quiet acoustic performance critical for HVAC and white-goods applications. Operating from 3.0-3.6 V at -40 C to +85 C industrial range, it withstands harsh factory-floor environments. Energy-efficiency algorithms such as sensorless FOC with flux-weakening maximize runtime on battery or solar-powered pumps. The 28-QFN package fits within space-constrained pump controller housings.
추천
Automotive HVAC Actuators
For automotive HVAC flap and blower actuators, the PIC24EP128MC202-I/MM (or its -E/MM AEC-Q100 sibling) drives small BLDC motors with precise speed and torque control. The MCU's PWM and ADC peripherals support sensorless or single-shunt current sensing in a compact 28-QFN footprint that fits inside actuator housings. LIN or CAN connectivity enables body-control-module integration. Operating from -40 C to +85 C industrial range, it handles under-hood thermal conditions when paired with the -E automotive variant. This application benefits from Microchip's automotive-qualified tool chain and functional safety documentation.
추천
Precision Servo Control
The PIC24EP128MC202-I/MM powers precision servo drives in robotics, CNC machines, and camera gimbals where deterministic real-time control is essential. Its 70 MIPS performance and multi-channel high-resolution PWM deliver smooth torque and position control, while the on-chip op-amps sample phase currents at high PWM rates for closed-loop feedback. The peripheral event trigger and DMA engine offload time-critical sampling from the CPU, freeing cycles for trajectory planning and kinematics. Industrial operating temperature and the 28-QFN package suit the demanding environments of factory automation.
추천
Sensorless BLDC Drivers
Sensorless BLDC designs benefit from the PIC24EP128MC202-I/MM's fast ADC and high-resolution PWM that sample back-EMF zero-crossings with sub-microsecond accuracy. The 70 MIPS CPU executes zero-crossing detection, commutation timing, and start-up algorithms in real time without external DSP chips. On-chip op-amps can be repurposed for back-EMF amplification in low-voltage designs, reducing component count. The MCU's 128 KB Flash accommodates sensorless algorithms plus optional UART/I2C communication for IoT-connected motor nodes in smart-home appliances and battery tools.

설계 노트
The 28-QFN-S EP package exposes a thermal pad beneath the die that must be soldered to the PCB for proper heat dissipation. Use a 4x4 to 6x6 array of thermal vias (0.3 mm drill, 0.5 mm pitch) connecting the exposed pad to an inner copper plane. Decouple VDD with 100 nF X7R ceramic placed within 3 mm of each VDD pin, plus a bulk 4.7-10 uF tantalum or polymer cap near the package. Place a ferrite bead or pi-filter between digital VDD and analog AVDD to minimize switching noise coupling into ADC measurements.
Estimated: at 70 MIPS continuous CPU activity and 3.3 V supply, core current draw is approximately 30 mA (~100 mW dissipation). The 28-QFN theta_JA is approximately 35 C/W on a 2-layer JEDEC test board, producing a ~3.5 C temperature rise per 100 mW. For industrial environments at 85 C ambient, ensure total dissipation including peripheral current stays below 0.6 W to maintain safe junction temperature under 125 C. Place temperature-sensitive analog traces away from the MCU exposed pad area.
Do not leave the MCLR pin floating - tie it to VDD via a 10 kohm pull-up resistor and a 100 nF cap to ground for noise immunity. The ICD pins (PGEC1/PGED1) must be pulled low during reset via 4.7 kohm resistors to avoid inadvertently entering debug mode on noisy resets. When migrating from PIC24FJ to PIC24EP, note that the EP series requires 3.3 V only; the 5 V-tolerant pins of the FJ family are not present here. Verify PWM channel mapping via PPS (Peripheral Pin Select) before locking the PCB layout.
