PIC24EP256GP204-H/PT Overview
An MCU (microcontroller unit) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (SRAM), peripherals, and I/O. The PIC24E family sits in the hierarchy: PIC24E -> 16-bit MCU -> microcontroller -> embedded computing -> semiconductor. The -H temperature suffix in PIC24 part numbers designates the high-temperature operating range from -40C to +150C, while the /PT suffix indicates a 44-pin TQFP package, and the suffix also signals AEC-Q100 qualification for automotive environments.
Key features include 4 KB of auxiliary Flash, multiple communication peripherals (UART, SPI, I2C, ECAN), a Parallel Master Port (PMP), and on-chip op amps with programmable gain that eliminate external analog front-end components. The CTMU enables precise time measurement (touch, proximity, flow) using a constant-current source, while the PTG coordinates complex peripheral timing sequences in software, freeing the CPU for application code.
Typical applications span automotive body and chassis modules, industrial motor control and variable-frequency drives, sensor signal conditioning, LED lighting controllers, low-cost medical instrumentation, and consumer appliance control panels where analog integration reduces BOM cost. The wide 3.0-3.6 V supply range and high-speed PWM outputs also suit digital power conversion.
Design consideration: this part carries the -H (high-temp) and -PT suffix combination reserved for AEC-Q100 automotive qualification. If your design does not require automotive temperature range or qualification, the -I/PT or -E/PT variants offer the same Flash/RAM at lower cost. Verify on the Microchip ordering code chart before selection.

Typical Applications
PIC24EP256GP204-H/PT is suitable for 6 applications: Automotive Body Control Modules, Industrial Sensor Signal Conditioning, Motor Control and Variable Frequency Drives, LED Lighting Controllers, Medical Point-of-Care Instrumentation, Consumer Appliance Control Panels.
Automotive Body Control Modules
The PIC24EP256GP204-H/PT's -40C to +150C operating range and AEC-Q100 qualification make it a drop-in fit for automotive body controllers. With 256 KB Flash, designers can host CAN-based body network stacks (the part includes an ECAN peripheral) along with lighting, mirror, and wiper control logic in one device. The three on-chip op amps condition sensor inputs (current, temperature, position) without external analog ICs, while the 12-bit ADC with 500 ksps throughput samples multiple body sensors per millisecond for closed-loop control. At 70 MIPS, the CPU handles LIN/CAN stack processing plus PTG-coordinated peripheral events without timing jitter. Compared with general-purpose -I grade parts, the -H suffix ensures the device survives under-hood thermal stress in BCM, HVAC, and seat-control modules.
Recommended
Industrial Sensor Signal Conditioning
The three integrated operational amplifiers, four comparators, and 12-bit ADC make the PIC24EP256GP204-H/PT a single-chip analog front end for industrial sensors. The on-chip op amps are programmable for inverting, non-inverting, and transimpedance configurations, eliminating external instrumentation amps in load-cell, thermocouple, and bridge-sensor designs. The CTMU provides sub-microsecond time measurements for capacitive touch, flow, and proximity sensing without an external timer IC. With 32 KB SRAM, designers can buffer substantial sensor sample buffers for FFT-based vibration analysis, and 256 KB Flash holds application plus calibration tables. At 3.3 V supply and 60 MIPS, this part replaces 8-bit MCU plus external signal-chain designs that previously required 4-5 ICs.
Recommended
Motor Control and Variable Frequency Drives
The PIC24EP256GP204-H/PT delivers 70 MIPS throughput that drives sensorless and sensored BLDC, PMSM, and stepper motor control loops at switching frequencies up to 20 kHz. Its high-speed PWM outputs with programmable dead-time, combined with the integrated op amps for current sensing, form a complete single-chip motor controller. The PTG (Peripheral Trigger Generator) coordinates ADC sampling precisely on PWM edges without CPU intervention, achieving sub-microsecond timing accuracy needed for field-oriented control. With 256 KB Flash, the firmware holds vector-control math libraries plus application code, while 32 KB SRAM buffers three-phase current and voltage reference frames. The H temperature grade supports motor drive stages operating near power electronics heat sources.
Recommended
LED Lighting Controllers
Architectural and automotive LED lighting controllers benefit from the PIC24EP256GP204-H/PT's 16-bit PWM resolution, 12-bit ADC for color-mixing feedback, and on-chip op amps for current-sense amplifiers. Each lighting channel requires precise PWM dimming to avoid flicker; the PIC24E PWM modules support sub-microsecond duty-cycle updates at 70 MIPS core speeds. Designers can implement DMX512, DALI, or CAN-based lighting protocols directly in firmware using 256 KB Flash, eliminating the need for an external lighting controller IC. The integrated comparators detect over-temperature and over-current faults within microseconds, providing hardware-level protection independent of software latency. AEC-Q100 qualification supports headlamp, tail-light, and interior ambient lighting modules.
Recommended
Medical Point-of-Care Instrumentation
Low-cost medical devices such as glucose meters, pulse oximeters, and handheld diagnostic probes leverage the PIC24EP256GP204-H/PT's integrated analog peripherals to reduce BOM cost below the threshold of dedicated ASSPs. The 12-bit ADC at 500 ksps captures photodiode and electrochemical sensor waveforms with adequate dynamic range for clinical-grade measurements. The three op amps provide the transimpedance, buffer, and gain stages typically required by optical sensors. The CTMU enables precise timing for fluorescence decay measurements used in lateral-flow assays. With 256 KB Flash, the firmware can host both measurement algorithms and user-interface graphics libraries, while the high-temp H grade allows sterilization-tolerant housing designs. AEC-Q100 is a strong signal of quality systems compliance.
Recommended
Consumer Appliance Control Panels
Washing machines, dishwashers, ovens, and HVAC controllers use the PIC24EP256GP204-H/PT as a single-chip user interface and motor/valve controller. The CTMU supports capacitive touch buttons without mechanical switches, while the high-speed PWM outputs drive variable-frequency compressor and fan motors. With 256 KB Flash, the firmware holds full graphical user-interface code plus Modbus, BACnet, or Wi-Fi/BLE stack stubs for IoT-enabled appliances. The integrated op amps sense current in heating elements and motors, eliminating discrete analog front ends. Compared with PIC18-based designs, the 16-bit core executes control loops with 2-3x faster response, improving energy efficiency and reducing audible noise from power-stage switching.

Design Notes
The PIC24EP256GP204-H/PT operates from a single 3.0-3.6 V supply on VDD/AVDD pins. Decouple each VDD pin with a 100 nF ceramic capacitor placed within 5 mm of the pin, and add a single 10 uF bulk capacitor per supply domain. Separate analog (AVDD/AVSS) from digital (VDD/VSS) ground returns using a star-ground or split-plane topology, joining them at a single point near the IC's VSS pin to avoid digital switching noise coupling into the 12-bit ADC reference.
At 70 MIPS core throughput with all peripherals active, the PIC24EP256GP204-H/PT typically draws 50-70 mA from VDD, dissipating approximately 200 mW. The 44-pin TQFP package has theta_JA around 50 C/W on a standard 4-layer JEDEC test board, supporting the full -40C to +150C junction temperature range. Estimated: junction temperature rise above ambient is roughly P_D x theta_JA = 0.2 W x 50 C/W = 10 C; for H-grade parts, this leaves ample margin to the 150 C absolute maximum.
Route the ICSP programming pins PGEC1/PGED1 (pins 41/42) directly to a 6-pin header with no series resistors, and bring out MCLR (pin 38) through a 10 kohm pull-up to VDD for in-circuit programming and debugging. If using the secondary oscillator (SOSC) for RTC, route the SOSCI/SOSCO traces (pins 36/37) symmetrically and guard them with a ground pour to minimize noise injection into the 32.768 kHz crystal. Place any CTMU current-source bypass capacitors within 3 mm of their associated ADC input pins.
Do not exceed 3.6 V on any VDD or AVDD pin - the PIC24E core uses an internal charge pump that can latch up at higher voltages. Configure unused I/O pins as outputs driving low to minimize shoot-through current. When using the ECAN peripheral, add a 120 ohm termination resistor between CANH and CANL only at the physical ends of the bus. Avoid driving capacitive loads > 50 pF directly on high-speed PWM output pins; use a gate driver IC instead.
The PIC24EP256GP204-H/PT's 12-bit ADC achieves specified ENOB (effective number of bits) only with a low-impedance input driver and proper anti-aliasing filter. For sensors with > 10 kohm source impedance, buffer the input with one of the on-chip op amps configured as a unity-gain follower before the ADC input. For high-speed ADC sampling at 500 ksps, route analog input traces as short microstrips with adjacent ground return and keep them away from PWM and digital switching signals.
