PIC24EP512GP202-I/SO 概要
A microcontroller (MCU) is a single-chip computer that combines a CPU core, program and data memory, and programmable peripherals. The PIC24E architecture is a 16-bit modified Harvard RISC design optimized for deterministic real-time performance with DSP extensions, making it part of the broader category of digital signal controllers (DSC) that bridges traditional 8-bit MCUs and full DSP processors. Within Microchip's portfolio, it sits between the dsPIC33 (DSC) and the PIC32 (32-bit) families.
Key differentiating features include superior ADC performance at up to 1.1 Msps with 12-bit resolution, four on-chip operational amplifiers configurable for signal conditioning, the CTMU enabling capacitive touch and precise time measurement, and the PTG peripheral for hardware-triggered sequencing of events without CPU intervention. The 512KB Flash (170K x 24 instruction words) and 48KB RAM allow complex firmware stacks while leaving room for bootloader and data-logging applications.
Typical applications span industrial motor control, power conversion, advanced sensor signal conditioning, capacitive touch human-machine interfaces, medical instrumentation, and high-performance consumer embedded systems. The wide SOIC package simplifies prototyping and rework versus QFP or QFN alternatives, which is valuable for low-volume industrial designs.
When designing with the PIC24EP512GP202, ensure VDD decoupling follows Microchip's recommended 0.1 µF + bulk capacitor placement, route analog and digital grounds per the datasheet's AGND/DGND layout guideline, and verify that the chosen programming/debug tool (such as MPLAB ICD 4 or PICkit 4) supports the 70 MIPS device ID. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

主な用途
PIC24EP512GP202-I/SO の用途: 7 件s: Industrial Motor Control, Capacitive Touch HMI, Precision Sensor Signal Conditioning, Power Conversion and Digital SMPS, Building Automation and HVAC, Audio Processing and Effects, Automotive Body and Comfort Modules.
Industrial Motor Control
The PIC24EP512GP202-I/SO fits industrial motor control drives due to its 70 MIPS core (sufficient for sensorless FOC algorithms on low-voltage BLDCs up to several kHz loop rate), integrated 12-bit 1.1 Msps ADC for current sensing via shunt resistors, and 48 KB RAM that hosts control loops plus a CAN or RS-485 comms stack. The four on-chip op-amps remove external current-sense amplifiers, shrinking the BOM and improving noise immunity by keeping analog signal paths on-die. Designers benefit from the wide 28-SOIC package for hand-reworkable prototypes and the 70 MIPS headroom over slower 40-MIPS PIC24F parts that cannot close FOC loops within required PWM periods.
おすすめ
Capacitive Touch HMI
The PIC24EP512GP202-I/SO suits capacitive touch human-machine interfaces because of its CTMU peripheral, which measures capacitance with femtofarad resolution and enables up to 32 touch channels without an external touch controller IC. The 512 KB Flash accommodates Microchip's mTouch library plus a full GUI framework, while 48 KB RAM supports real-time event scheduling. The wide industrial temperature range and 70 MIPS throughput guarantee responsive touch latency under cold-crank or high-CPU-load conditions, and the 28-SOIC package simplifies hand-soldered prototype boards versus QFP alternatives that complicate rework.
おすすめ
Precision Sensor Signal Conditioning
The PIC24EP512GP202-I/SO works in precision sensor signal chains thanks to its four on-chip operational amplifiers, which can be configured for strain-gauge bridges, thermocouples, and photodiode transimpedance stages without external op-amps. The 12-bit ADC at 1.1 Msps oversamples and averages for effective 16-bit resolution, while the 48 KB RAM buffers calibration tables and digital-filter state. Its 70 MIPS DSP engine runs real-time IIR/FIR filters on the conditioned signal, replacing dedicated DSP parts in cost-sensitive medical and industrial instrumentation. The wide 28-SOIC package enables through-hole-friendly breadboarding during sensor algorithm development.
おすすめ
Power Conversion and Digital SMPS
The PIC24EP512GP202-I/SO excels in digitally controlled switch-mode power supplies because the 70 MIPS core and DSP extensions handle voltage-mode and peak-current-mode control loops with sub-microsecond sample-to-PWM-update latency. Its built-in comparators enable hardware cycle-by-cycle current limiting that bypasses CPU latency entirely, while the PTG peripheral sequences multi-phase interleaved PWMs without software overhead. The 512 KB Flash stores complex state machines for PFC, LLC, and synchronous-rectifier timing, and the wide 28-SOIC footprint provides a thermally robust path for moderate switching losses at industrial temperature ranges.
おすすめ
Building Automation and HVAC
The PIC24EP512GP202-I/SO is well-suited to building automation controllers running BACnet, Modbus, or KNX protocols because the 512 KB Flash holds full stack implementations plus application code, while 48 KB RAM buffers Modbus TCP frames during network bursts. Its 70 MIPS performance handles multiple concurrent communication stacks without missing real-time sensor sampling deadlines. The four on-chip op-amps interface directly with 4–20 mA or 0–10 V industrial transducers, eliminating external signal-conditioning boards. Wide industrial temperature rating plus the 28-SOIC package's ease of hand-prototyping benefits HVAC field installations.
おすすめ
Audio Processing and Effects
The PIC24EP512GP202-I/SO handles audio processing tasks such as guitar-effects, mixers, and consumer audio DSP because its 70 MIPS core with DSP extensions processes 16-bit audio samples at 48 kHz with headroom for biquad and delay-line algorithms. The 12-bit DAC plus PWM combined with DMA-driven peripherals enable multi-channel audio output without CPU intervention. The 512 KB Flash stores large preset libraries and lookup tables, while 48 KB RAM buffers audio frames. The wide 28-SOIC package is preferred by audio hobbyists for through-hole-friendly pedal designs and educational platforms.
おすすめ
Automotive Body and Comfort Modules
The PIC24EP512GP202-I/SO can be deployed in automotive body controllers (non-safety domains) such as lighting, mirror, and seat controllers where the AEC-Q100-Qualified 'EP' variants are not required and the industrial -40 to +85 °C operating window suffices. Its LIN-compatible UART, multiple PWM channels, and CTMU support capacitive switch panels, while the 512 KB Flash accommodates CAN/LIN stacks plus application firmware. The four on-chip op-amps condition sensor signals directly. The wide 28-SOIC package simplifies board rework during automotive validation cycles, and the 70 MIPS core easily handles real-time seat-control algorithms.

設計ノート
Place a 0.1 µF ceramic decoupling capacitor within 5 mm of every VDD pin, and add a bulk 10 µF tantalum or ceramic capacitor on the main VDD rail per the Microchip PIC24EP512GP202 family datasheet power-supply layout guideline. The wide industrial 28-SOIC package dissipates the 70 MIPS core adequately under typical ambient loads, but at sustained 60 MHz operation the device draws roughly 70–80 mA, so verify regulator headroom.
Route analog and digital grounds according to the datasheet's AGND/DGND guidance: star-ground the analog and digital grounds at a single point near the VDD decoupling. The four on-chip op-amps are sensitive to digital switching noise; keep their traces short, avoid running digital return currents underneath analog regions, and place guard rings around high-impedance analog inputs.
A common pitfall is selecting the wrong configuration bits: leaving the JTAG enabled disables RB7/RB8/RB9 for I/O, and an incorrect oscillator configuration prevents the PLL from achieving 60 MHz. Always use MPLAB X IDE with the latest device family pack (DFP) and verify FOSC matches the crystal or external clock before programming the 70 MIPS device ID.
Estimated: at VDD = 3.3 V, FOSC = 60 MHz, all peripherals active, the PIC24EP512GP202-I/SO typically consumes 70–80 mA, dissipating approximately 0.23–0.26 W. The 28-SOIC wide-body has a theta_JA of roughly 60–70 °C/W, resulting in a 15–18 °C junction temperature rise above ambient — well within the 85 °C industrial ceiling with proper PCB copper pour.
