PIC24EP32GP204T-I/ML 概要
A 16-bit PIC microcontroller (MCU) is a member of the microcontroller family built on a 16-bit modified Harvard architecture with separate program and data buses. PIC24E devices sit in the broader taxonomy: 16-bit MCU -> PIC24 family -> PIC24E sub-family -> PIC24EP "GP" general-purpose series. The 70 MIPS core executes most instructions in one cycle, while the 16-bit data path, large register file and DSP-class instructions deliver significantly more throughput per MHz than 8-bit alternatives.
Key features of this variant include a 70 MIPS (60 MHz) CPU with DSP instructions, 32 KB self-programmable Flash, 4 KB SRAM, two op-amps usable for signal conditioning before the ADC, up to 35 I/O, multiple serial interfaces (UART, SPI, I2C) and a 12-bit ADC with 9 channels minimum. The 44-QFN (8x8 mm) package includes an exposed pad (EP) for thermal dissipation, and the device is qualified for the -40C to +85C industrial temperature range.
Architecturally, the PIC24EP "GP" series combines a deterministic single-cycle engine with rich analog integration: two operational amplifiers can be paired with the ADC for sensor-interface front-ends, while the CTMU provides time-based touch and current measurement. The PTG can sequence peripheral events autonomously, offloading timing-critical tasks from the CPU. Compared with PIC24F devices, the EP core adds DSP instructions and a much faster instruction rate.
Typical applications include industrial sensor conditioning, motor-control signal chains, LED lighting controllers, USB-to-UART bridges using the on-chip UART, and general-purpose embedded control in consumer or industrial products. The combination of integrated op-amps, PTG and 70 MIPS throughput also makes the part well-suited to closed-loop control tasks such as BLDC commutation and PID loops.
When designing with this part, take care to observe the 3.0 V to 3.6 V supply window - this is NOT a 5 V tolerant MCU. Decouple VDD/AVDD with 100 nF and 10 uF ceramics placed close to the pins, bond the exposed pad to a continuous ground plane for thermal relief, and configure unused I/O as outputs to minimise current draw. The "T" suffix denotes tape-and-reel packaging; the "I" in the operating range indicates the industrial -40C to +85C grade.

主な用途
PIC24EP32GP204T-I/ML の用途: 6 件s: Industrial Sensor Conditioning, BLDC Motor Control, LED Lighting Controllers, USB-to-UART / Embedded Bridge, Consumer Appliance Control, Touch HMI and Capacitive Sensing.
Industrial Sensor Conditioning
The PIC24EP32GP204T-I/ML's integrated dual op-amps and 9-channel 12-bit ADC make it well-suited for analog sensor front-end designs in industrial environments. The two op-amps can be configured as a low-noise instrumentation pair for bridge sensors (strain gauges, load cells) directly feeding the ADC, eliminating external analog ICs and reducing BOM cost. Its 70 MIPS throughput (60 MHz) enables on-chip linearisation and digital filtering of sensor data in real time, with 32 KB Flash accommodating mid-sized algorithm code and 4 KB SRAM handling ring buffers for sampled data. The CTMU enables capacitive-touch sensing for HMI panels, while comparators support threshold-based alarms. Operating from 3.0-3.6 V and qualified to -40C to +85C industrial range, it can be deployed directly on factory-floor PLCs without additional thermal management.
おすすめ
BLDC Motor Control
The PIC24EP32GP204T-I/ML is a strong fit for low-to-mid voltage BLDC, PMSM, and stepper motor control loops. Its 70 MIPS core with DSP instructions (MAC, ED, AC) handles Park/Clarke transforms, PI current controllers and space-vector modulation at typical 10-20 kHz PWM rates. The integrated op-amps and comparators interface directly with shunt-based current sensing and back-EMF detection, while the 9-channel 12-bit ADC samples phase currents and DC-bus voltage in real time. The Peripheral Trigger Generator (PTG) can sequence ADC sampling relative to PWM edges autonomously, offloading timing-critical tasks from the CPU. Microchip's AN1078 application note provides reference firmware for sensorless BLDC on this family. The 44-QFN package exposes up to 35 I/O for PWM, encoder and fault inputs.
おすすめ
LED Lighting Controllers
Architectural and commercial LED lighting controllers benefit from the PIC24EP32GP204T-I/ML's combination of DSP-grade processing, integrated op-amps for current sensing, and PWM peripherals. The 70 MIPS core runs multi-channel dimming algorithms, color-mixing math (CIE XYZ / sRGB transforms), and DMX-512 or DALI protocol stacks at full speed without offloading. The ADC monitors LED-string current via op-amp shunts, while comparators provide fast over-current shutdown. The 32 KB Flash comfortably holds DMX/DALI protocol tables and dimming curve lookup data, and 4 KB SRAM handles per-channel PWM update buffers. Operating from 3.0-3.6 V and industrial -40C to +85C, it pairs naturally with constant-current LED drivers such as the CL8800 or TPS92515.
おすすめ
USB-to-UART / Embedded Bridge
The PIC24EP32GP204T-I/ML is frequently deployed as an embedded communication bridge in industrial gateways and consumer products, where its UART, SPI and I2C peripherals are exposed to a host via USB- or CAN-attached transceivers. The 70 MIPS core handles protocol parsing, command queuing and error recovery without dropping frames, and the 32 KB Flash stores protocol state machines and configuration data. The CTMU can be repurposed for diagnostics or tamper detection. Designers can pair the part with an MCP2200 USB-to-UART bridge or MCP2515 CAN controller for industrial-grade fieldbus interfaces. The 44-QFN footprint keeps the BOM compact and the exposed thermal pad enables continuous operation at 60 MHz without thermal throttling.
おすすめ
Consumer Appliance Control
White-goods, HVAC thermostats and small kitchen appliances benefit from the PIC24EP32GP204T-I/ML's 70 MIPS throughput and integrated analog peripherals. The two op-amps interface with NTC thermistors or pressure transducers for closed-loop temperature control, while the 9-channel ADC reads multiple sensors in sequence with hardware averaging. The comparators enable fast over-temperature or over-current shutdown without software latency. 4 KB SRAM comfortably holds user-interface state, scheduling buffers and small LCD framebuffers. The industrial -40C to +85C operating range covers the under-cabinet and outdoor-rated appliance use cases. With 35 I/O, designers can drive keypads, character LCDs, and triac-controlled heaters directly.
おすすめ
Touch HMI and Capacitive Sensing
The PIC24EP32GP204T-I/ML's integrated CTMU (Charge Time Measurement Unit) enables robust capacitive-touch sensing for HMI panels, eliminating dedicated touch ICs in many cases. Combined with the 9-channel ADC, two op-amps, and 70 MIPS CPU, designers can implement 10-20 touch electrodes with on-chip gesture recognition. The DSP instructions accelerate FFT-based proximity algorithms, while 4 KB SRAM holds recent sample windows for noise-robust baseline tracking. The 44-QFN package allows ultra-compact HMI modules behind glass or plastic overlays. Industrial -40C to +85C temperature support covers outdoor kiosks, factory HMI panels and appliance front panels, and the part operates reliably from 3.0-3.6 V with USB-powered or battery-friendly supplies.

設計ノート
The PIC24EP32GP204T-I/ML operates strictly from 3.0 V to 3.6 V and is NOT 5 V tolerant on any pin. Decouple each VDD pin (5 and 30) with a 100 nF X7R ceramic placed within 5 mm of the pin, and add a bulk 10 uF ceramic per VDD/AVDD pair. AVDD (pin 12) should be tied to the same 3.3 V rail with its own 100 nF decoupling capacitor. Failure to keep ripple below 50 mVpp on AVDD will couple noise directly into the ADC measurements.
Estimated: at 60 MHz full-load CPU activity, typical core current is 25 mA (1.8 mA/MHz typical for PIC24E). At 3.3 V this yields ~83 mW of internal dissipation. The 44-QFN (8x8) exposed pad (pin 45, the die substrate) MUST be soldered to a continuous ground copper plane of at least 1 square inch to keep junction temperature rise under 20 C/W. Without this thermal pad bond, theta_JA rises to over 60 C/W and the device may throttle or fail at sustained high load.
Route the analog inputs (AN0-AN9) away from switching digital traces to minimise ADC crosstalk. Keep analog ground (AVSS, pin 13) connected to the digital ground (VSS) at a single point near the IC, using a wide trace or via array to avoid ground loops. Place the 100 nF + 10 uF decoupling network on AVDD immediately adjacent to pin 12. Use an unbroken top-layer pour over the entire QFN exposed pad region and stitch it down with a 4x4 via array to the inner ground plane.
Do NOT apply 5 V to any I/O - PIC24EP devices are 3.3 V only. Always use the internal weak pull-ups (CNPUx registers) for unconnected inputs instead of leaving them floating, since floating inputs on the PIC24 can cause excess current draw and unstable oscillator behaviour. The MCLR pin (pin 11) MUST be tied to VDD through a 10 kohm resistor for normal operation, and a 100 nF capacitor to VSS for ICSP programming; omitting MCLR bias will prevent the device from running.
