PIC24EP32GP203-I/TL 概要
An MCU, or microcontroller unit, is a single integrated circuit that combines a CPU core, program memory, data memory, and a range of peripheral interfaces on one die. The PIC24EP family occupies a specific niche in this hierarchy: 16-bit modified Harvard microcontrollers tuned for high-performance signal conditioning, motor control, and general-purpose embedded applications that exceed the capability of 8-bit PIC MCUs but do not require a full Cortex-M-class core. The PIC24E family hypernym chain runs: 16-bit MCU -> PIC24 -> PIC24EP -> general purpose family, within the broader semiconductor taxonomy of microcontroller -> embedded processor -> integrated circuit. Compared with 8-bit PIC16/PIC18 parts, the PIC24E doubles or quadruples instruction throughput and adds native DSP instructions.
Key features include dual 16-channel 10-bit ADCs with 1.1 Msps sampling rate (12-bit equivalent ADC mode), two op-amps, two comparators, a Peripheral Trigger Generator (PTG) for autonomous peripheral sequencing, four 16-bit timers, four DMA channels, and a CTMU (Charge Time Measurement Unit) for capacitive touch and current measurement. Communication interfaces include UART, SPI, I2C, and ECAN, providing flexible connectivity for sensor, display, and industrial control networks.
The PIC24E core architecture is a 16-bit modified Harvard CPU with a 24-bit instruction word, supporting single-cycle multiply, hardware divide, and zero-overhead looping. With 70 MIPS execution, the core can perform complex DSP filter algorithms, PID motor-control loops, and protocol stacks without offloading to external coprocessors. The 36-VTLA package also integrates a low-power sleep mode down to 25 nA typical, well-suited for battery-aware IoT edge nodes.
Typical applications include industrial sensor conditioning, BLDC/PMSM motor control (with field-oriented control algorithms), capacitive-touch human-machine interfaces, UPS and solar inverter control, LED lighting drivers with PFC, and portable medical instrumentation. The wide ADC bandwidth also suits audio front ends and power-metering ICs.
Design consideration: when migrating from PIC24F to PIC24EP, ensure the application uses a 3.0V-3.6V VDD supply because PIC24EP devices do not support 5V operation. Use the Peripheral Trigger Generator (PTG) to offload tightly timed ADC-DMA sequences from the CPU and to minimize interrupt latency in deterministic control loops.

主な用途
PIC24EP32GP203-I/TL の用途: 6 件s: Industrial Sensor Conditioning, BLDC / PMSM Motor Control, Capacitive-Touch HMI, UPS and Solar Inverter Control, LED Lighting Drivers with PFC, Portable Medical Instrumentation.
Industrial Sensor Conditioning
The PIC24EP32GP203-I/TL fits industrial sensor conditioning hubs because it integrates dual 16-channel 10-bit ADCs at 1.1 Msps and two built-in op-amps, removing the need for external signal-conditioning stages. Used as the hub for a 4-20 mA loop, RTD bridge, or strain-gauge front end, the part digitizes up to 32 analog inputs with hardware DMA offload, freeing the 70 MIPS core to run linearization and polynomial calibration algorithms. The 3.0 V - 3.6 V supply matches industrial 24 V buck-rails (after LM7805/LM1117 regulation), and the -40 C to +85 C temperature grade covers most factory-floor environments. Compared with discrete ADC + MCU architectures, the integrated solution cuts PCB area by 30-40 percent and reduces BOM cost.
おすすめ
BLDC / PMSM Motor Control
The PIC24EP32GP203-I/TL drives field-oriented-control (FOC) loops for small BLDC and PMSM motors up to 200 W when paired with an external gate driver. Its 70 MIPS execution easily sustains 20 kHz current-control loops, the four 16-bit timers provide dedicated PWM channels, and the dual ADCs sample phase currents simultaneously. Compared with 8-bit PIC18 parts, the 16-bit Harvard core executes Clarke/Park transforms and SVM modulation in roughly one-third the cycles. The integrated op-amps condition current-sense shunt signals directly, while the CTMU measures back-EMF for sensorless startup. For higher-power FOC above 1 kW, upgrade to the dsPIC33EP family, which adds SMPS peripherals and DSP multiply-accumulate.
おすすめ
Capacitive-Touch HMI
The PIC24EP32GP203-I/TL is well suited to capacitive-touch human-machine interfaces because its CTMU (Charge Time Measurement Unit) measures capacitance to femtofarad resolution without an external touch IC. With 32 KB Flash, the part runs Microchip's mTouch firmware library for self-cap and mutual-cap touch-sensor scanning on up to 16 buttons or a 4x4 matrix. The 70 MIPS core executes proximity detection and gesture recognition in real time, and the integrated op-amps buffer analog sliders/wheels directly. Compared with discrete touch ICs + MCU designs, the integrated approach reduces PCB traces, BOM cost, and firmware complexity.
おすすめ
UPS and Solar Inverter Control
The PIC24EP32GP203-I/TL is used in low-power UPS and solar micro-inverter controllers where 70 MIPS execution, the Peripheral Trigger Generator (PTG), and dual ADCs enable deterministic MPPT and grid-synchronization loops. The PTG sequences ADC conversions and PWM updates autonomously, freeing the core for housekeeping and Modbus/CAN communications. The 32 KB Flash holds the MPPT algorithm, grid-relay logic, and anti-islanding code; the 4 KB RAM holds moving-average filter state and PID variables. Compared with low-end PIC16F designs, the PIC24EP triples the PWM frequency, enabling smaller magnetics in the inverter's LC filter.
おすすめ
LED Lighting Drivers with PFC
The PIC24EP32GP203-I/TL drives commercial LED luminaires with active power-factor correction and constant-current control. Its four 16-bit timers generate PWM at up to 1 ns resolution for high-frequency dimming and DALI/0-10 V dimming interfaces. The dual 10/12-bit ADCs sense input voltage, input current, and output current simultaneously, and the integrated op-amps close the PFC current loop with low-offset error. Compared with analog PFC + analog driver designs, the digital architecture enables tighter THD (<10%) and easier firmware upgrade for new dimming standards.
おすすめ
Portable Medical Instrumentation
The PIC24EP32GP203-I/TL powers portable medical devices such as glucose meters, pulse oximeters, and single-channel ECG strips. Its 70 MIPS core runs DSP filters (low-pass, high-pass, notch) for ECG denoising in real time, while the dual ADCs digitize PPG and ECG signals simultaneously. The CTMU handles touch-button inputs on the device enclosure without external touch ICs. The 25 nA typical sleep current and 3.0 V - 3.6 V supply suit battery-powered designs with coin-cell or Li-ion power. Compared with 8-bit designs, the 16-bit core doubles the SNR of the digitized waveform, improving diagnostic accuracy at equivalent power.

設計ノート
Estimated: The PIC24EP32GP203-I/TL operates from 3.0 V to 3.6 V; do not connect to 5 V rails as the PIC24E family does not support 5 V tolerance on digital I/O. Place a 10 uF bulk + 100 nF decoupling capacitor pair within 5 mm of the VDD pin and repeat for AVdd. Add a ferrite bead between VDD and AVdd if analog performance below 10 LSB is required. The exposed thermal pad must be soldered to a continuous ground pour to provide thermal dissipation at elevated ambient temperatures.
Estimated: A common migration mistake is assuming PIC24EP GPIO is 5 V tolerant like PIC24F or PIC18F - it is NOT. Driving any I/O above VDD + 0.3 V can latch up the part. When designing with the CTMU for capacitive touch, follow Microchip AN1250 layout rules: keep the touch sensor traces short, route them away from switching signals, and add a ground guard ring around each sensor pad to prevent false triggers from neighboring traces.
Estimated: Place the 60 MHz crystal within 5 mm of the OSC1/OSC2 pins, with a continuous ground pour beneath. Keep ADC traces short and routed over a continuous analog ground island; do not cross analog and digital traces. The Peripheral Trigger Generator (PTG) lets you sequence ADC-DMA conversions deterministically - use it to reduce interrupt load by up to 60 percent in motor-control and PFC loops.
Estimated: At 70 MIPS in a 36-VTLA (5x5 mm) package with exposed thermal pad soldered to a 1 square inch 1 oz copper pour, theta_JA is approximately 35 C/W. Industrial-grade operation at 85 C ambient is well within thermal limits for the typical 30 mA active supply current. For closed-enclosure designs above 60 C ambient, derate by 1 mA per 5 C to maintain margin.
