PIC24EP256MC202T-E/SO 概要
A 16-bit microcontroller (MCU) is an embedded processor that balances computational throughput with deterministic real-time control. The PIC24E family uses a modified Harvard architecture with a 16-bit data path, 24-bit instruction word, and a hardware DSP engine, occupying the tier between 8-bit MCUs and full 32-bit Cortex-M devices. This class of MCU is widely used in digital-power conversion, BLDC/PMSM motor commutation, sensor-fusion edge nodes, and automotive body controllers where PWM precision, deterministic interrupt latency, and analog integration reduce the bill of materials.
Key features of the PIC24EP256MC202T-E/SO include a 60 MIPS core, 256 KB self-programmable Flash with ECC, 32 KB SRAM, dedicated motor-control PWM with 7.14 ns PWM resolution, three on-chip op-amps usable as current-sense amplifiers, four high-speed analog comparators, a 10/12-bit ADC with up to 1.1 Msps conversion rate, and a USB 2.0 full-speed OTG transceiver. Connectivity options include I2C, SPI, UART/USART, IrDA, LIN, and CAN, simplifying integration with inverter companion, BLDC gate drivers, and isolated communication channels.
The device supports 3.0V-3.6V single-supply operation, has 21 general-purpose I/O pins, and integrates a real-time clock and calendar, a charge-time measurement unit, and a peripheral trigger generator that synchronizes ADC sampling to PWM edges. These peripherals allow single-chip implementation of field-oriented control loops for 3-phase PMSM/BLDC motors without external DSP chips.
Typical applications include automotive HVAC blowers, electric power-steering pumps, BLDC drone ESCs, robotic servos, industrial variable-frequency drives, and high-density fan controllers. The combination of AEC-Q100 grade-1 qualification and integrated analog makes the part particularly attractive for 12V/24V automotive body and chassis subsystems. Compared with ARM Cortex-M0+ alternatives, the PIC24E offers deterministic interrupt latency and on-chip op-amps that reduce external analog components.
When designing with this MCU, allocate at least 4 layers for the 28-SOIC layout to route the high-current motor traces away from sensitive analog inputs. Decouple VDD with 100 nF + 10 uF ceramic capacitors placed within 5 mm of the supply pins, and use a guarded star-ground topology for the op-amp feedback traces to avoid PWM-induced switching noise coupling into current-sense amplifiers.

主な用途
PIC24EP256MC202T-E/SO の用途: 6 件s: Automotive HVAC Blower Motor Control, BLDC Drone Electronic Speed Controller, Industrial Variable-Frequency Drive, Robotic Servo and CNC Spindle Controller, Server Fan and Cooling Controller, Solar Micro-Inverter Power Stage.
Automotive HVAC Blower Motor Control
The PIC24EP256MC202T-E/SO is well-suited for automotive HVAC blower motor control because it combines AEC-Q100 grade-1 qualification with three on-chip op-amps for current sensing and 7.14 ns MCPWM resolution for quiet sinusoidal commutation. The 60 MIPS core executes FOC algorithms with sub-microsecond loop times, while the integrated QEI interfaces directly to Hall or encoder feedback without external logic. Compared with discrete MCU+op-amp+gate-driver designs, this single-chip integration reduces BOM cost by approximately 30% and PCB area by 50%. Designers typically use the on-chip op-amps as current-sense amplifiers across low-side shunt resistors, with the peripheral trigger generator synchronizing ADC sampling to PWM edges for jitter-free current measurement at 20 kHz switching frequency.
おすすめ
BLDC Drone Electronic Speed Controller
The PIC24EP256MC202T-E/SO drives 3-phase BLDC motors in drone ESCs because its 60 MIPS throughput runs sensorless FOC at 32 kHz loop rates while the four on-chip comparators back-EMF-sense at zero crossing. The 256 KB Flash accommodates full FOC libraries plus telemetry protocols (DShot, ProShot) without external memory. The 28-SOIC package fits within size-constrained 4-in-1 ESC stacks. Hardware design note: route the three op-amp current-sense traces as guarded differential pairs and keep the bootstrap-capacitor traces short to minimize PWM-induced noise coupling. Expected efficiency at 30 A continuous is 96-98% with proper gate-driver selection (e.g., Microchip MCP8024).
おすすめ
Industrial Variable-Frequency Drive
The PIC24EP256MC202T-E/SO serves as the control MCU in industrial VFDs because its deterministic interrupt latency and 7.14 ns PWM resolution deliver precise V/Hz and sensorless vector control for induction motors up to 5 kW. The AEC-Q100 qualification extends to industrial -40 C to +125 C environments, and the integrated LIN/UART interfaces simplify connection to HMI panels. The 32 KB SRAM is sufficient for full Clarke/Park transforms plus a 1024-point FFT for vibration monitoring. Compared with ARM Cortex-M0+ VFD controllers, this PIC24E delivers 2x the PWM resolution at lower BOM cost thanks to integrated op-amps and comparators.
おすすめ
Robotic Servo and CNC Spindle Controller
The PIC24EP256MC202T-E/SO drives robotic servo motors and CNC spindles because its QEI module directly interfaces to incremental encoders at up to 5 Mpps while the MCPWM outputs generate the precise torque commands. The 256 KB Flash stores full PID plus feed-forward control tables, and the 32 KB RAM buffers trajectory planning data. The three on-chip op-amps handle torque-current, speed, and position-loop feedback in parallel. For 6-axis robot arms, the chip's 21 GPIO pins support 3 encoders plus endstop inputs, enabling per-axis closed-loop control from a single MCU.
おすすめ
Server Fan and Cooling Controller
The PIC24EP256MC202T-E/SO manages server cooling fans because its 7.14 ns PWM resolution enables silent low-RPM operation, while the integrated comparators detect rotor lock with 1 us response time. The AEC-Q100 grade supports 24/7 operation at elevated server-inlet temperatures. Hardware note: use the on-chip op-amp as a current-sense amplifier for stall detection. The 256 KB Flash accommodates full closed-loop PID plus failure-mode firmware, and the LIN/UART interfaces connect to baseboard management controllers (BMCs) for telemetry reporting.
おすすめ
Solar Micro-Inverter Power Stage
The PIC24EP256MC202T-E/SO is appropriate for solar micro-inverter MPPT control because its 60 MIPS core executes perturb-and-observe MPPT at 50 kHz while the high-resolution MCPWM drives the full-bridge at 100 kHz switching. The AEC-Q100 grade supports outdoor -40 C to +125 C operation. The on-chip op-amps sense input current and output voltage simultaneously, eliminating external instrumentation amplifiers. The 256 KB Flash stores MPPT tables plus grid-synchronization firmware for IEEE 1547 compliance. Compared with discrete MCU+FPGA MPPT designs, this single-chip solution reduces BOM cost by 40%.

設計ノート
Estimated: at VIN=3.3 V, Iactive=70 mA (60 MIPS with all peripherals active), power dissipation is approximately 230 mW. Place 100 nF + 10 uF ceramic decoupling capacitors within 5 mm of pins 11 and 28 (VDD). Use a star-ground topology with VSS tied to a single ground pour, and keep analog VSS (AGND, internally bonded to VSS) isolated from switching-return currents.
The 28-SOIC (7.50 mm body) requires a 4-layer PCB minimum for switching-motor applications. Route the MCPWM output traces (RB0-RB5) as short direct paths to the gate driver, and use a guarded differential pair for the op-amp current-sense traces to minimize PWM-induced common-mode noise. Place a ground ring around each current-sense shunt resistor and stitch vias every 5 mm along the trace edges.
The 7.14 ns MCPWM resolution produces edge rates of approximately 50 V/ns at typical gate-driver inputs. This couples 10-20 mV of switching noise into analog traces if not properly isolated. Use a 4-layer stackup with continuous ground plane beneath the MCU, and route analog signals (ANx, op-amp inputs) on a layer adjacent to ground. The peripheral trigger generator should be configured to trigger ADC sampling 500 ns after PWM edge transitions to allow settling.
Do not connect MCLR directly to VDD without a 10 kohm pull-up resistor; floating MCLR causes intermittent resets. The on-chip op-amps have a unity-gain bandwidth of approximately 10 MHz - do not attempt to use them as video amplifiers. The 256 KB Flash is partitioned into 85.5K x 24 instruction words; erase block size is 512 instructions, so design the firmware-update strategy around page-aligned writes.
