PIC24EP256MC202-H/SO Descripción general
A 16-bit microcontroller (MCU) is a single-chip processor core with on-chip Flash program memory, RAM, peripherals and I/O designed to combine deterministic real-time control with DSP-style arithmetic. The PIC24E family targets motor control, power conversion and high-end general-purpose embedded control - the PIC24EP256MC202-H/SO sits in the 'MC' (Motor Control) sub-family, with high-resolution PWM, dedicated quadrature encoder interfaces, op-amp outputs and an analog comparator designed to drive field-oriented control (FOC) loops.
Key features include 256 KB (85.5K x 24) self-programmable Flash with EEPROM emulation, 32 KB SRAM, 4 KB instruction cache, 70 MIPS performance at 70 MHz Fosc with 4x PLL, high-speed PWM (PWM with 7.5 ns resolution), dual analog comparators with 5 ns response, two on-chip operational amplifiers (5 MHz GBW) usable for current sensing, a 10-bit ADC at 1.1 Msps (12-bit option at 500 ksps), and a Peripheral Trigger Generator (PTG) for hardware-state-machine event sequencing. Communication peripherals include SPI, I2C, UART, CAN, and ECAN.
The device operates from 3.0 V to 3.6 V, integrates a low-jitter PLL, an LDO-based core supply, and a brown-out reset. Its 28-SOIC form factor suits single/three-phase BLDC/PMSM sensorless and sensored drives up to ~1 kW, while the higher-temperature -H grade supports under-hood automotive and industrial environments.
Typical applications include BLDC/PMSM sensorless and sensored motor control, field-oriented control (FOC) drives, switched-mode power supplies (PFC + LLC), uninterruptible power systems, photovoltaic inverters, and industrial automation with CAN-connected nodes.
When designing with the -H/SO, provide a low-impedance 3.3 V rail, place the 10 uF + 0.1 uF decoupling pair within 5 mm of the VDD pins, and reserve the ICSP/ICD pins (PGECx/PGEDx) for in-circuit debug. Ensure unused comparators are configured to defined states to avoid current spikes.

Aplicaciones típicas
PIC24EP256MC202-H/SO es adecuado para 6 aplicacións: BLDC / PMSM Sensorless Motor Control (FOC), Switched-Mode Power Supply (PFC + LLC), Solar / Photovoltaic Inverter Control, Uninterruptible Power Supply (UPS) and Inverter, Industrial Servo Drive with CAN Networking, Automotive Auxiliary Pump / Fan Motor Control.
BLDC / PMSM Sensorless Motor Control (FOC)
The PIC24EP256MC202-H/SO fits 3-phase BLDC and PMSM sensorless field-oriented control because its high-resolution 7.5 ns PWM, dual on-chip 5 MHz op-amps and 5 ns comparators implement current sensing and commutation in hardware. The 70 MIPS core runs the FOC and MTPA loops in well under 10 us. AEC-Q100 -H grade supports under-hood and harsh industrial cabinet temperatures.
Recomendado
Switched-Mode Power Supply (PFC + LLC)
For digital PFC + LLC power supplies, the PIC24EP256MC202-H/SO drives the high-resolution PWM, samples the input voltage/current through its 1.1 Msps 10-bit ADC, and runs cycle-by-cycle control loops. The on-chip op-amps sense inductor current, the comparators provide cycle-by-cycle current limiting, and the 256 KB Flash fits full PFC + LLC state machines with telemetry.
Recomendado
Solar / Photovoltaic Inverter Control
The PIC24EP256MC202-H/SO is well suited to small photovoltaic inverters and micro-inverters because the high-resolution PWM synchronizes MPPT switching, the dual op-amps measure PV string current, and the CAN/ECAN peripheral networks multiple inverter modules. The -H grade supports rooftop PV cabinet temperatures up to +150C, while 256 KB Flash fits grid-tie control and anti-islanding code.
Recomendado
Uninterruptible Power Supply (UPS) and Inverter
In online UPS designs, the PIC24EP256MC202-H/SO runs the inverter control loop with the high-resolution PWM, monitors battery voltage/current with the on-chip op-amps, and orchestrates transfer between mains and battery via ECAN messaging to other cabinet modules. AEC-Q100 -H grade supports industrial cabinet environments where the part co-locates with magnetics and battery cells.
Recomendado
Industrial Servo Drive with CAN Networking
For servo drives on a CANopen / DeviceNet industrial bus, the PIC24EP256MC202-H/SO combines the on-chip ECAN controller with the motor-control peripherals. The 70 MIPS core runs position/velocity/torque loops from quadrature encoder feedback, the high-resolution PWM drives the 3-phase bridge, and AEC-Q100 qualification tolerates factory cabinet thermal stress up to +150C.
Recomendado
Automotive Auxiliary Pump / Fan Motor Control
Automotive auxiliary pumps, HVAC blowers and cooling fans use the PIC24EP256MC202-H/SO for AEC-Q100 qualified BLDC control on a 12 V bus. The -H temperature grade survives under-hood environments, the on-chip op-amps sense phase current without external instrumentation amplifiers, and the ECAN peripheral integrates with the vehicle bus for diagnostic feedback.

Notas de diseño
Decouple VDD (pins 6 and 28) with a 10 uF bulk + 0.1 uF ceramic pair within 5 mm of the pins. Place a 1 uF ceramic on VCAP (pin 7) for the on-chip core LDO. Hold unused analog inputs at VSS to prevent cross-conduction. According to the Microchip PIC24EP256MC202 datasheet, brown-out reset must be left enabled at the BOR level matching your supply tolerance to avoid partial Flash writes during transient brown-out.
At 70 MIPS continuous operation with all peripherals active, the 28-SOIC package dissipation stays well under 1 W, but in a fully sealed under-hood automotive enclosure the junction-to-ambient thermal resistance (~70 C/W) can still push the die toward 110 C ambient. Provide copper pour on VDD/VSS planes and route thermal vias under the exposed thermal pad area where available. Use the -H grade's +150 C ceiling for derating.
Common pitfalls: (1) forgetting to configure unused comparators to a defined state can add 1-2 mA quiescent; (2) using a 20 MHz crystal with the 4x PLL when the design needs 70 MHz (use 10 MHz base); (3) leaving the ICSP pins PGEC1/PGED1 floating when not using debug (recommend 4.7 k pull-up to avoid spurious resets); (4) failing to clear the ADC channel selection after a sequence scan can yield phantom readings. Always refer to the Microchip errata document for the silicon revision you are using.
