PIC24EP32MC202-I/SP Présentation
A 16-bit MCU (microcontroller unit) is a single-chip computer built around a 16-bit data path, on-chip Flash program memory, RAM, and a rich set of peripherals such as ADCs, PWMs and communication interfaces. The PIC24E family sits in Microchip's dsPIC33/PIC24EP performance tier, positioned above PIC18F and below dsPIC33EP DSP controllers in the PIC taxonomy, and is classified as a Motor Control MCU optimized for closed-loop FOC, BLDC and PFC control loops.
Key features include a 70 MIPS modified Harvard core, six 16-bit PWM channels with high-speed PWM (up to 1 ns edge resolution), 21 general-purpose I/O pins, a 6-channel 10-bit/12-bit ADC with up to 1.1 Msps conversion rate, two internal operational amplifiers for current sensing, four 16-bit timers, two I2C, two SPI and one UART interface, and 4 KB of RAM. The device also includes a 32-bit CRC engine, a real-time clock and multiple interrupt priority levels for deterministic motor control latency.
Technically, the PIC24EP32MC202 integrates dedicated motor-control peripherals (PWM, op amps and ADC with tight synchronization) that remove the need for an external DSP for many sensorless and sensored BLDC / PMSM designs. The high-speed PWM module can be time-base synchronized with the ADC, allowing sampling of phase currents at the exact PWM midpoint to maximize noise rejection.
Typical applications include BLDC and PMSM motor controllers, sensorless fan and pump drives, power inverters, industrial drives, and digital power supplies with PFC. The wide operating temperature range and on-chip op amps simplify analog front-end design for shunt-based current sensing. When designing with this MCU, ensure the VDDCORE pin is decoupled with 10 uF + 0.1 uF, and reserve one PWM channel pair for ADC trigger to maintain deterministic current sampling.

Applications typiques
PIC24EP32MC202-I/SP convient pour 6 applications: Sensorless BLDC Motor Control, PMSM Servo Drives, Power Factor Correction (PFC) Stage, Industrial BLDC Fan and Pump Drives, Solar Micro-Inverter Control, Digital Switch-Mode Power Supply (SMPS) Primary-Side Control.
Sensorless BLDC Motor Control
The PIC24EP32MC202-I/SP's 70 MIPS core, six high-resolution PWM channels (1 ns edge), two on-chip op amps for shunt current sensing and hardware-triggered 12-bit ADC together enable single-chip sensorless BLDC field-oriented control (FOC). Sampling three phase currents at the PWM midpoint rejects switching noise, and the integrated op amps eliminate external analog front-end ICs. The 32 KB Flash runs Microchip's MPLAB X motorBench FOC firmware plus a small UART/CAN service stack, while 4 KB RAM holds state variables, PI controllers and Clarke/Park transform buffers. Designers get full FOC torque and speed loops inside a single 28-pin SPDIP package for fans, pumps and appliance drives.
Recommandé
PMSM Servo Drives
For permanent-magnet synchronous motor (PMSM) servo drives used in robotics, CNC spindles and industrial automation, the PIC24EP32MC202-I/SP delivers the deterministic interrupt latency and high-resolution PWM required for smooth torque and velocity loops. The 70 MIPS core completes an FOC iteration (Clarke, Park, inverse Park, SVPWM) in under 10 us, leaving headroom for an Ethernet or CANopen communication stack. The 28-SPDIP package is ideal for prototype servo controllers, while the 21 I/O pins drive H-bridge gate drivers, encoder inputs and end-of-travel limits. Industrial-grade -40 C to +85 C operation supports factory-floor deployment.
Recommandé
Power Factor Correction (PFC) Stage
The PIC24EP32MC202-I/SP is well suited for digital boost-PFC front stages in switch-mode power supplies. Its high-speed PWM can generate the 50-100 kHz boost switching frequency, while the dedicated ADC trigger synchronized to the PWM edge samples the AC line current and inductor current at the exact zero-crossing of the switching ripple. The internal op amps condition the current-sense signal before the ADC. Six PWM channels can drive both the PFC boost switch and a downstream DC-DC converter. The 32 KB Flash stores the digital PI controller, line-voltage RMS calculation and brown-out protection firmware for digital PFC.
Recommandé
Industrial BLDC Fan and Pump Drives
For HVAC fans, refrigerator compressors and circulation pumps, the PIC24EP32MC202-I/SP provides single-chip sensorless BLDC commutation with on-chip op amps and PWM that handles the entire 3-phase inverter. The industrial -40 C to +85 C temperature rating supports outdoor and refrigeration environments, and the 28-SPDIP through-hole package simplifies assembly in white-goods manufacturing. Six PWM outputs drive the 3-phase bridge plus a brake/regeneration channel, while UART or I2C interfaces provide a service-port for diagnostics and firmware updates in the field.
Recommandé
Solar Micro-Inverter Control
In small solar micro-inverters (250-500 W), the PIC24EP32MC202-I/SP runs both the MPPT algorithm and the grid-tie inverter control loops in one MCU. The high-speed PWM generates the 50 kHz full-bridge switching waveform synchronized to the 50/60 Hz line, while the on-chip 12-bit ADC samples PV panel voltage, current and grid voltage for MPPT and anti-islanding. The 32 KB Flash holds MPPT, grid synchronization PLL and anti-islanding firmware; 4 KB RAM holds the SOGI-FLL state. The 28-SPDIP package allows through-hole assembly for low-volume micro-inverter prototypes and field trials.
Recommandé
Digital Switch-Mode Power Supply (SMPS) Primary-Side Control
For digital peak-current-mode LLC and phase-shift full-bridge SMPS primary-side controllers, the PIC24EP32MC202-I/SP delivers 70 MIPS of DSP-class throughput with the high-speed PWM and ADC that digital SMPS demands. The ADC can be triggered from the PWM edge to sample the primary current and the resonant tank voltage at a deterministic instant, while the 16-bit PWM drives the primary-side MOSFETs at 100-500 kHz. The 32 KB Flash stores the digital compensator (Type-II/Type-III), soft-start and protection firmware. The 28-SPDIP package fits into standard SMPS control-board form factors.

Principaux différenciateurs
- Higher Flash density in pin-compatible package (vs PIC24EP32MC202-E/SP)

- Application-tuned peripheral integration (vs dsPIC33EP32MC202-I/SP)
Notes de conception
Estimated: Decouple each VDD pin with a 10 uF bulk + 0.1 uF ceramic placed within 5 mm of the IC, and add a separate 10 uF + 0.1 uF pair on AVDD. The PIC24EP32MC202 has separate digital and analog supply pins (VDD, VDDCORE, AVDD); failure to decouple VDDCORE causes erratic operation at 70 MIPS.
At 70 MIPS switching the I/O pins with 20 mA loads, the 28-SPDIP package dissipates well under 1 W. For -40 C to +85 C industrial operation, no heatsink is needed, but derate the I/O sourcing current above +70 C ambient by 2-3% per degree to stay within the 150 mA total pin-current limit per datasheet DS-70000657H.
Route the crystal traces (OSC1/OSC2) within 1 cm of the MCU and guard them with a ground pour to avoid jittering the 60 MHz core clock. Place the ICSP programming header (PGEC1/PGED1 on RB6/RB7) on a 0.1 inch grid so a Microchip ICD or PICkit can clip on without removing the MCU from the board during development.
Do not drive any I/O pin above VDD + 0.3 V or below VSS - 0.3 V - the PIC24EP32MC202 has no 5 V tolerance on its I/O. If your design mixes 3.3 V MCU with 5 V signals, use the MCP14A0901 gate driver or a level shifter; failing to level-shift will latch-up the MCU. Also, the PWM outputs are push-pull only and cannot drive tri-state buses without external buffers.
Informations de conformité
RoHS / REACH status not stated in the verified web data; refer to Microchip's product environmental compliance page. AEC-Q100 not applicable - this is an industrial-grade MCU. Automotive designers should use the PIC24EP32MC202-H/SP variant (AEC-Q100 qualified) instead.
