PIC24HJ128GP202T-I/MM 概述
What is a PIC24H 16-bit microcontroller? The PIC24H is a high-performance 16-bit MCU family from Microchip Technology that occupies the mid-range position between the 8-bit PIC18 and the 32-bit PIC32MX. Architecturally, a PIC24H combines a 16-bit data path with a 24-bit instruction word, giving it code density comparable to 32-bit cores while keeping interrupt latency predictable for hard real-time control loops. The PIC24H family is also pin-compatible with the dsPIC33F DSC family, so a designer can migrate to DSP extensions by simply swapping the chip.
Key features of the PIC24HJ128GP202T-I/MM include the 40 MIPS core, an integrated 12-bit A/D converter with up to 10 channels, multiple communication peripherals (UART, SPI, I2C), and a 16-bit timer/capture/compare module. The -I suffix indicates the industrial temperature grade of -40C to +85C. The QFN-S 28 package is the smallest 28-pin option in this family and exposes a thermal pad for improved heat spreading in space-constrained layouts.
Technically, the device operates from a single 3.0-3.6V supply and supports up to 16 MIPS at 3.0V, scaling to 40 MIPS at 3.3V. It includes a JTAG programming/debug interface and uses Microchip's ICSP (In-Circuit Serial Programming) for in-field firmware updates. The combination of high throughput, large memory and rich analog/digital peripherals makes it suitable for closed-loop control, motor drive front ends, and sensor processing.
Typical applications include motor control (BLDC and PMSM), industrial automation and sensor hubs, advanced sensing front ends, switched-mode power supply control, and embedded data acquisition. The wide peripheral mix and 5V-tolerant digital inputs make it a strong fit for mixed-signal industrial boards.
When designing with this part, plan the PCB layout so that the exposed pad on the QFN package is soldered to a copper pour. Do not exceed 3.6V on VDD; although the digital inputs are 5V-tolerant, the supply must remain within the 3.0-3.6V window for the analog blocks to meet datasheet performance.
This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes beyond what is found in the manufacturer datasheet alone, giving procurement and design engineers a single reference for the PIC24HJ128GP202T-I/MM.

典型应用
PIC24HJ128GP202T-I/MM 适用于 6 应用s: BLDC and PMSM Motor Control, Industrial Sensor Hubs, Switched-Mode Power Supply Control, Embedded Data Acquisition, Automotive Body Electronics, Consumer Audio and Appliance Control.
BLDC and PMSM Motor Control
The PIC24HJ128GP202T-I/MM's 40 MIPS core, 16-bit timers with PWM, and 10-channel 12-bit ADC make it well suited for sensorless and sensored BLDC and PMSM motor control. Microchip motor-control firmware libraries target this exact family for trapezoidal and sinusoidal commutation; the 8 KB RAM is enough for Park/Clark transforms and PI controllers. The 28-QFN package is footprint-compatible with the dsPIC33F family, letting designers step up to DSP-based field-oriented control later without changing the PCB. Real-world designs deliver 6 kHz current-loop bandwidth at 24V/10A on this MCU.
推荐
Industrial Sensor Hubs
In industrial automation the PIC24HJ128GP202T-I/MM acts as a sensor-hub aggregator, reading analog signals through its 12-bit ADC and forwarding data via UART, SPI, or I2C to a PLC or gateway. The industrial -40C to +85C temperature grade ensures reliable operation in factory environments. The 5V-tolerant digital inputs simplify direct connection to 5V legacy sensors while the MCU runs from a 3.3V rail, avoiding level shifters in mixed-signal boards. With 128 KB Flash and 8 KB RAM, firmware can include Modbus, IO-Link, or proprietary protocols without external memory.
推荐
Switched-Mode Power Supply Control
The PIC24HJ128GP202T-I/MM is widely deployed in digital SMPS controllers because its 40 MIPS throughput supports high-frequency control loops (200 kHz+ with multi-pole digital compensation). The high-speed ADC captures current and voltage feedback, and the 16-bit timer generates the PWM with nanosecond resolution. Microchip's application notes use this family for PFC plus LLC resonant converter designs. The 28-QFN package and exposed thermal pad keep power dissipation manageable when the MCU runs at 40 MIPS continuously.
推荐
Embedded Data Acquisition
For compact multi-channel data loggers, the PIC24HJ128GP202T-I/MM offers 10 ADC channels sampling at 500 ksps aggregate, enough for vibration, temperature, and current monitoring in a single chip. The 128 KB Flash supports RTOS-based stacks such as FreeRTOS or Microchip Harmony, while 8 KB RAM holds circular sample buffers for short bursts. The MCU streams results over UART or SPI to a host computer. Industrial users value the wide operating-temperature range for outdoor and chassis-mount installations.
推荐
Automotive Body Electronics
Although the -I variant of the PIC24HJ128GP202T-I/MM targets industrial temperature, the same die is qualified to automotive standards in other package options. Designers use this MCU in non-safety body modules such as HVAC flap control, seat-position memory, and ambient lighting where 16-bit precision and CAN/LIN connectivity are needed. The 28-QFN footprint is suitable for tight module packaging behind instrument panels, and the 5V-tolerant inputs interface directly with 12V automotive signals via external resistor dividers.
推荐
Consumer Audio and Appliance Control
The PIC24HJ128GP202T-I/MM is used in mid-range consumer appliances such as coffee machines, washing-machine user interfaces, and audio mixers, where 16-bit DSP-like math is needed to process user input and drive displays. The exposed-pad QFN package dissipates heat well in enclosed appliance cabinets, and the JTAG interface speeds firmware development. With 128 KB Flash, designers can integrate USB device stacks, capacitive-touch libraries, and graphic LCD drivers in a single firmware image.

设计说明
Estimated: At 40 MIPS continuous operation with VDD = 3.3V, core current is approximately 30 mA and I/O current can reach 100 mA total, giving power dissipation near 0.43W. The 28-QFN package's exposed thermal pad should be soldered to a copper pour of at least 25 mm2 (about 0.04 sq inch) on top and bottom layers with multiple thermal vias; without this, theta_JA exceeds 60 C/W and the device can approach its 85C industrial limit in enclosed appliances.
Place a 0.1 uF ceramic decoupling capacitor within 2 mm of every VDD pin and a 10 uF bulk capacitor at the board-level power entry. Keep the MCLR reset trace short (< 25 mm) and add the recommended 10 kohm pull-up to VDD. Because the QFN-28 has its pin 1 indicator as a dot, orient the package mark to match the PCB silkscreen to avoid confusion during rework.
Do not exceed 3.6V on VDD or AVDD, even though digital inputs are 5V-tolerant - the analog block loses linearity above 3.6V. When designing motor-control PWMs, ensure dead-time control registers are configured before enabling the PWM output, otherwise shoot-through can damage the power stage. Also, the ICSP pins PGEC1/PGED1 must not be pulled low at reset if you want to enter normal run mode - use them only during programming.
