PIC24EP256GP204-E/ML 概要
What is a PIC24E microcontroller? The PIC24E is a 16-bit MCU family within the broader PIC24F/24H/24E MCU taxonomy, which in turn sits below dsPIC33 DSCs and above 8-bit PIC16/PIC18 devices in Microchip's MCU hierarchy. PIC24E devices use a modified Harvard architecture with a 16-bit data path, dedicated DSP instructions, and 24-bit instruction words, balancing code density and computational throughput for embedded control applications.
Key differentiating specifications of the PIC24EP256GP204-E/ML include 35 general-purpose I/O pins, four 16-bit timers, two UART/SPI/I2C modules, a 10/12-bit ADC module, and a 10-bit DAC. The 60 MIPS core supports complex DSP-like computations in real time, while the PTG allows autonomous peripheral sequencing without CPU intervention. The -E temperature grade extends operation from -40C to +125C, making this part suitable for harsh-environment automotive and industrial applications.
The architectural highlight is the integration of analog peripherals directly accessible from the application layer: two on-chip op-amps can be configured for signal conditioning at the sensor input, while the CTMU enables capacitive touch sensing and precision time measurement. The Peripheral Trigger Generator coordinates ADC sampling, PWM updates, and timer events without software overhead, freeing CPU cycles for application logic.
Typical applications include automotive sensor conditioning, industrial motor control, medical patient monitoring, and HVAC fan control. The op-amp integration reduces BOM cost by eliminating external signal-chain components, while the AEC-Q100 qualification makes the part drop-in ready for under-the-hood automotive modules.
A primary design consideration is that the PIC24EP256GP204-E/ML operates from a 3.0V to 3.6V supply - a 3.3V regulator is required when sourcing from a 5V rail. The 44-QFN (8x8 mm) exposed pad must be soldered to the PCB ground plane for thermal dissipation and electrical grounding.

主な用途
PIC24EP256GP204-E/ML の用途: 6 件s: Automotive Sensor Signal Conditioning, Industrial Motor Control (BLDC/PMSM), Medical Patient Monitoring Devices, HVAC Fan and Pump Controllers, Capacitive Touch User Interfaces, Industrial IoT Edge Sensor Nodes.
Automotive Sensor Signal Conditioning
The PIC24EP256GP204-E/ML's on-chip operational amplifiers and AEC-Q100 qualification make it well-suited for automotive sensor signal conditioning modules. With two integrated op-amps, the MCU can amplify low-level sensor outputs (such as pressure, temperature, or position transducers) without requiring external analog front-end ICs, reducing BOM cost and PCB area. The 60 MIPS core provides sufficient bandwidth for real-time linearization and digital filtering, while the PTG can autonomously trigger ADC sampling synchronized with PWM excitation. The -40C to +125C operating range ensures reliable operation in engine bay or under-hood environments. Designers should place 100nF decoupling capacitors near each VDD pin and follow Microchip AN1416 automotive layout guidelines to meet CISPR 25 EMI requirements.
おすすめ
Industrial Motor Control (BLDC/PMSM)
For industrial BLDC or PMSM motor control, the PIC24EP256GP204-E/ML's 60 MIPS performance and motor-control peripherals deliver field-oriented control (FOC) at switching frequencies up to 20 kHz. The PIC24EP MC family variant PIC24EP256MC204 is preferred for motor control, but the GP204 variant still supports scalar V/f control in cost-sensitive fans and pumps. The Peripheral Trigger Generator coordinates ADC sampling on PWM center-aligned events, eliminating software jitter and improving current-sense accuracy. The 256KB Flash accommodates complex state machines and field-weakening algorithms. The AEC-Q100 qualification ensures operation in industrial enclosures reaching +85C ambient. Designers should size the PCB ground plane to dissipate the QFN's 35 C/W thermal resistance at full CPU load.
おすすめ
Medical Patient Monitoring Devices
The PIC24EP256GP204-E/ML is suitable for low-power medical monitoring peripherals where 16-bit processing of bioelectric signals is required. The CTMU (Charge Time Measurement Unit) enables precision time-of-flight measurements for flow sensing, while the on-chip comparators provide hardware-level threshold detection for ECG or pulse-oximeter front-ends. The 32KB SRAM buffers sampled data between interrupts, and the 256KB Flash stores calibration tables and application firmware. The 3.3V operation simplifies Li-ion battery-powered designs, though the -E automotive temperature grade exceeds typical medical device requirements (which usually need only -40C to +85C, supported by the -I variant). Designers should validate against IEC 60601-1 EMI/EMC and patient leakage requirements at the system level.
おすすめ
HVAC Fan and Pump Controllers
The PIC24EP256GP204-E/ML's combination of analog comparators, op-amps, and PWM peripherals suits residential HVAC fan and water-pump controllers. The on-chip op-amp monitors motor current via a shunt resistor, enabling closed-loop torque control without external instrumentation amplifiers. The 60 MIPS CPU executes PI control loops at 10 kHz with margin for soft-start ramps and fault detection algorithms. The Peripheral Trigger Generator sequences ADC conversions synchronized with zero-crossing detection on the AC mains input, improving power factor correction accuracy. AEC-Q100 qualification provides headroom for installation in attic or boiler-room environments where temperatures can exceed +70C. Designers should add MOV protection on the AC input and follow IPC-2221 creepage/clearance rules for line-voltage isolation.
おすすめ
Capacitive Touch User Interfaces
The CTMU peripheral in the PIC24EP256GP204-E/ML enables robust capacitive touch sensing for industrial control panels and appliance front panels. By measuring charge time on capacitive sensors, the MCU detects button presses, sliders, and proximity events with sub-pF resolution. The 60 MIPS core supports up to 16 touch channels scanned at 100 Hz with hardware-averaged noise filtering. The 256KB Flash stores complex touch gesture recognition algorithms, while the 32KB RAM buffers raw scan data for processing. The AEC-Q100 grade allows deployment in kitchen appliances and outdoor equipment. Designers should follow Microchip AN1258 capacitive touch design guidelines and use guard-ring PCB patterns to suppress moisture false-triggers.
おすすめ
Industrial IoT Edge Sensor Nodes
The PIC24EP256GP204-E/ML serves as the central controller in industrial IoT edge sensor nodes that require local signal processing before wireless transmission. The 256KB Flash accommodates MQTT-SN or CoAP protocol stacks along with sensor processing logic, while the 32KB RAM buffers sensor data for edge analytics. UART, SPI, and I2C interfaces connect to wireless modules like LoRa, Sub-GHz transceivers, or BLE modems. The 60 MIPS core handles local decision-making to reduce wireless transmission frequency, saving power. AEC-Q100 qualification ensures operation in factory environments with electrical noise and wide temperature swings. Designers should pair this MCU with an external crypto-authentication IC for secure boot and OTA firmware updates in industrial IoT deployments.

設計ノート
The PIC24EP256GP204-E/ML operates from a single 3.0V-3.6V supply; place a 10uF bulk capacitor plus 100nF ceramic decoupling capacitors within 5 mm of each VDD/VDDC pin pair. The core supply (VDDC) requires its own 10uF + 100nF decoupling network. A low-dropout regulator (such as Microchip MCP1700) is recommended when sourcing from a 5V rail. For battery-powered designs, ensure the regulator's quiescent current is below 10 uA to preserve battery life.
The 44-QFN (8x8 mm) package has a typical theta_JA of 35 C/W when the exposed pad is soldered to a 1 oz copper ground plane of at least 1 square inch. Estimated: at 60 MIPS full CPU activity (typical core current ~30 mA at 3.3V), power dissipation is ~100 mW, resulting in a junction temperature rise of only 3.5 C above ambient - well within safe operating limits. However, high I/O toggle rates or peripheral-heavy operation can double core current, so reserve thermal margin for worst-case operation.
The QFN exposed pad must be soldered to the PCB ground plane using an array of thermal vias (typically 9-16 vias of 0.3 mm diameter) to provide both electrical grounding and thermal dissipation. Place the ICSP programming header (PGECx/PGEDx) on the same side of the board as the MCU with traces no longer than 50 mm to ensure reliable in-circuit programming. The analog supply AVDD and reference AVSS pins require their own 100nF decoupling capacitors placed within 3 mm of the pins.
Common design pitfalls include: (1) Forgetting the 100nF cap on VCAP (core voltage regulator output) which will cause the MCU to fail to start. (2) Using the wrong ICSP pair - any PGECx/PGEDx pair works but they must be used as a matched pair (e.g., PGEC2 with PGED2 only). (3) Not configuring the CONFIG registers for the correct oscillator mode, leading to the device running at the wrong speed. (4) Exceeding 3.6V on any I/O pin when interfacing 5V logic - use level shifters or PIC24FJ variants with 5V-tolerant I/O instead.
