PIC24EP256GP202-H/MM Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and programmable peripherals into one device. The PIC24E family belongs to Microchip's 16-bit dsPIC/PIC24 architecture (modified Harvard), positioned between the 8-bit PIC18 family and the 32-bit PIC32MX line. Within the broader hierarchy, PIC24E belongs to digital signal controllers and microcontrollers -> embedded computing -> semiconductors. The 'H' suffix designates a high-temperature grade beyond the standard -40C to +85C industrial range.
Key features include a 70 MIPS (60 MHz) modified-Harvard core with single-cycle MAC, dual op amps, a Charge Time Measurement Unit (CTMU), a Peripheral Trigger Generator (PTG), and high-speed ADC performance optimized for general-purpose embedded applications. The device integrates 21 analog channels, multiple UART/SPI/I2C peripherals, and supports up to 32 KB of SRAM alongside the 256 KB Flash.
Architecturally, the PIC24E uses a 24-bit instruction word with 16-bit data path, offering higher code density than typical 32-bit cores while retaining deterministic interrupt latency. The integrated op amps and CTMU reduce BOM count for sensor-conditioning front-ends such as temperature, capacitive touch, and current sensing.
Typical applications include industrial sensor conditioning, motor control signal chain pre-processing, capacitive touch interfaces, LED lighting controllers, and automotive body electronics where the high-temperature grade is required. The exposed thermal pad and 6x6 mm QFN footprint allow compact PCB designs with efficient heat dissipation.
When designing with this part, plan for the 3.3V single supply, configure the JTAG/ICSP programming interface early, and verify op-amp gain and bandwidth for your analog front-end. The 'H' grade requires attention to derating near the upper temperature limit; consult the manufacturer datasheet for thermal performance data.

Typical Applications
PIC24EP256GP202-H/MM is suitable for 7 applications: Industrial Sensor Signal Conditioning, Capacitive Touch Interface, Automotive Body Electronics, LED Lighting Controller, Motor Control Signal Pre-Processing, Industrial IoT Edge Sensor Node, Medical Device Signal Processing.
Industrial Sensor Signal Conditioning
The PIC24EP256GP202-H/MM is well suited for industrial sensor-conditioning front-ends thanks to its dual integrated op amps and CTMU (Charge Time Measurement Unit). The op amps provide configurable gain for thermocouple, RTD, and bridge-sensor signal paths, while the CTMU enables precise time-based measurements for capacitance-to-digital conversion. The 256 KB Flash accommodates calibration tables and linearization algorithms, and the 70 MIPS core executes polynomial compensation in microseconds. The H temperature grade allows deployment in -40C to +150C environments such as factory-floor sensor hubs, motor-drive current sensors, and process-control analog front-ends. Place the device on a 4-layer PCB with the exposed pad soldered to a 0.5 square-inch copper pour for thermal dissipation at high ambient.
Recommended
Capacitive Touch Interface
The PIC24EP256GP202-H/MM's CTMU combined with the internal op amps enables robust capacitive touch button, slider, and proximity-sensor implementations without external analog components. The CTMU produces a precision current source that charges the touch-sensor capacitance, and the ADC measures the resulting voltage in time. The 70 MIPS core can debounce, filter, and process up to 32 touch channels while running the user interface protocol. The H temperature grade suits outdoor keypads, automotive interior controls, and appliance front panels. Expect 10-15 touch channels at 70 MIPS with single-cycle ADC integration, and pair with a chemically-strengthened glass overlay for harsh-environment deployment.
Recommended
Automotive Body Electronics
The H temperature grade and 256 KB Flash make the PIC24EP256GP202-H/MM a candidate for automotive body-electronics modules such as seat controllers, mirror modules, HVAC blend-door actuators, and lighting controllers. The device operates reliably at +125C ambient with the H grade's +150C headroom for short-term temperature excursions. The integrated op amps handle motor-current sensing and thermistor inputs, while the PTG (Peripheral Trigger Generator) chains ADC conversions and PWM updates without CPU intervention. Note: AEC-Q100 qualification status was not confirmed in the verified data; verify with Microchip directly for production automotive designs. For 12V battery-direct applications, pair with an MCP1790 LDO regulator and TVS protection.
Recommended
LED Lighting Controller
The PIC24EP256GP202-H/MM is a strong fit for intelligent LED lighting controllers driving multiple channels of high-brightness LEDs. The 70 MIPS core executes 16-bit PWM at high resolution for dimming and color mixing, while the CTMU measures LED junction temperature via an external thermistor. The integrated op amps close the loop on constant-current LED drivers, replacing discrete op-amp + MOSFET circuits. The 256 KB Flash stores DMX512, DALI, or proprietary lighting protocols, and the H temperature grade supports enclosed luminaire operation up to +150C. Pair with MCP16301 buck converters for high-voltage AC-DC front-end and MCP6L2 op amps for additional analog channels beyond the two internal op amps.
Recommended
Motor Control Signal Pre-Processing
While the GP variant lacks the dedicated PWM/QEI peripherals of the MC family, the PIC24EP256GP202-H/MM still serves as a signal pre-processor for low-cost motor-control boards. The integrated op amps sense phase currents via shunt resistors, and the ADC samples them at high speed with the 70 MIPS core computing the control loop. The PTG triggers ADC conversions precisely synchronized to PWM edges from a co-processor. The H temperature grade suits BLDC fan controllers, small appliance pumps, and HVAC damper actuators. For full motor-control loops, switch to the PIC24EP256MC202 sibling which adds high-resolution PWM and quadrature encoder interface; both share the 28-QFN footprint.
Recommended
Industrial IoT Edge Sensor Node
The PIC24EP256GP202-H/MM is suitable for industrial IoT edge nodes that aggregate sensor data, perform local analytics, and communicate via UART/SPI to a wireless module. The 256 KB Flash runs lightweight TCP/IP stacks (Microchip MLA), MQTT-SN clients, or proprietary sensor protocols, while the 32 KB SRAM buffers network packets and time-series data. The integrated op amps condition sensor inputs directly, and the CTMU supports energy harvesting measurement. The H temperature grade supports outdoor and factory-floor deployment. Pair with an RN2483 LoRa module for long-range connectivity, or an ATWINC1500 for Wi-Fi; the PIC24E handles the protocol stack and sensor fusion while the wireless module handles RF.
Recommended
Medical Device Signal Processing
The PIC24EP256GP202-H/MM is appropriate for medical-device peripheral modules such as pulse-oximeter front-ends, infusion-pump motor control, and patient-monitor signal conditioning. The dual integrated op amps condition photodiode currents or ECG electrode signals, and the 70 MIPS core executes digital filters in real time. The 256 KB Flash stores calibration coefficients, and the H temperature grade supports autoclave-sterilizable external modules. Note: FDA/IEC 60601-1 medical certification is the OEM's responsibility; verify with Microchip the device's reliability data and FIT rates for your medical application class. Pair with MCP6N11 instrumentation amp for ECG and AD8232 for heart-rate monitoring front-end.

- Integrated dual op amps and CTMU (vs PIC24EP128GP202-H/MM)
- GP variant with full PIC24E peripheral set (vs PIC24EP128MC202-H/MM)

Design Notes
The PIC24EP256GP202-H/MM requires a single 3.3V supply (3.0V to 3.6V range). Place 100 nF decoupling capacitors as close as possible to every VDD pin and a bulk 10 uF tantalum or ceramic capacitor near the device. For H-grade designs operating at +150C, use X7R or C0G/NP0 ceramic capacitors rated to +150C minimum to avoid derating. Estimated power consumption at 70 MIPS full activity is approximately 60 mA; plan for 100 mA peak when peripherals are active.
The exposed thermal pad (EP) on the 28-VQFN package must be soldered to a copper pour of at least 0.5 square inches on the top layer for adequate heat dissipation. Connect the EP to the ground plane via multiple thermal vias (at least 9 vias in a 3x3 array, 0.3 mm drill). At +150C ambient operation, the junction-to-ambient thermal resistance theta_JA is approximately 30-40 C/W with proper thermal design - verify in your specific PCB layout.
For the 28-VQFN 6x6 mm package, the land pattern should follow IPC-7351 nominal-density guidelines with 0.5 mm pitch pads. Keep analog traces (op-amp inputs, ADC inputs) short and away from digital switching signals. Route the crystal oscillator traces (OSC1/OSC2) symmetrically within 5 mm of the device, surrounded by a ground guard ring. The ICSP programming pins (PGECx/PGEDx) should be brought out to a 2x5 header for in-circuit debugging without interfering with the application circuit.
Do not confuse the PIC24EP256GP202-H/MM with the dsPIC33EP256GP502 variants which have the same package but different peripheral sets. Verify the exact OPN (Ordering Part Number) on the device package before programming. The Configuration bits must be programmed for the correct oscillator mode and watchdog timer setting before code execution; missing configuration programming results in a blank device that cannot be debugged. For H-grade parts, derate the maximum operating frequency at +150C ambient per the datasheet thermal performance curve.
The internal op amps on PIC24EP256GP202-H/MM have rail-to-rail input stages; observe the input common-mode voltage range near both rails as specified in the datasheet. When using the op amps to sense small signals (<10 mV), add an RC low-pass filter (1 kHz cutoff) at the op-amp output before the ADC input to attenuate PWM switching noise. The 10-bit ADC achieves best linearity when the source impedance is below 5 kOhm; use the internal op amp as a buffer when sensing higher-impedance sources.
