Артикул: PIC24FJ32GP202-I/ML ✓ АктивенPIC24FJ32GP202-I/ML Обзор
A PIC24 MCU is a 16-bit RISC microcontroller within the broader embedded-controller hierarchy of MCU, semiconductor, and programmable logic. The PIC24 family combines a compact instruction set, digital peripherals, analog conversion functions, and event-driven control capabilities. This makes the device useful when a system needs deterministic peripheral handling without relying on a higher-cost application processor.
The PIC24FJ32GP202-I/ML provides 32 KB of ECC Flash and 8 KB of SRAM, together with interfaces including I2C, SPI, and UART. According to the Microchip product information, the PIC24FJ GP2 family also includes core-independent peripherals and supports low-power sleep operation, including sleep current down to a few hundred nanoamperes while retaining core-independent peripheral functionality. These characteristics support responsive systems that spend substantial time between active transactions.
At a maximum clock frequency of 32 MHz, the device executes up to 16 million instructions per second. ECC Flash protects stored program data against detected memory errors, while the 8 KB SRAM provides working space for protocol buffers, sampled data, and control state. The industrial-temperature ordering code identifies the component as the -I/ML variant, with the ML package code corresponding to the 28-QFN 6x6 mm outline.
Typical applications include USB-connected control accessories, low-power sensor nodes, industrial data-acquisition equipment, compact USB-to-serial interfaces, and battery-operated embedded controllers. The combination of 32 MHz processing, multiple serial interfaces, ECC program memory, and a low-power sleep mode is particularly useful in designs that balance protocol flexibility, memory reliability, and board area.
PCB planning should preserve the exposed-pad land pattern and thermal and electrical requirements of the 28-QFN package. Place decoupling capacitors close to the supply pins, route high-current and sensitive signals carefully, and follow the manufacturer's pin-description table when assigning every I/O. Firmware should also use the core-independent peripherals where low-power wake-up behavior is important.
This product page combines the manufacturer's device information with package-specific sourcing guidance, application-oriented engineering notes, and same-footprint replacement analysis. These details help engineers evaluate the PIC24FJ32GP202-I/ML before committing to a 28-QFN PCB layout or migration plan.

USB Control Accessories
The PIC24FJ32GP202-I/ML fits compact USB control accessories that require a 32 MHz PIC24 core, 32 KB of ECC Flash, and 8 KB of RAM in a 28-QFN 6x6 mm package. Its I2C, SPI, and UART resources can connect sensors, indicators, and external interface devices without consuming a large peripheral bus. The two DMA channels can transfer protocol or control data with less CPU intervention. Before committing the schematic, verify the exact GP202 USB resources and dedicated pin requirements against the Microchip documentation because related family members differ in USB capability.
Рекомендуется
Low-Power Sensor Nodes
The PIC24FJ32GP202-I/ML suits low-power sensor nodes because its PIC24 family supports sleep current down to a few hundred nanoamperes while retaining core-independent peripheral functionality. The 32 MHz core provides responsive handling during active measurement periods, while the 32 KB ECC Flash stores application code and the 8 KB RAM holds recent samples. Use core-independent peripherals for periodic wake-up and timing, and select the clock, sensor, and communications configuration carefully because total standby consumption also depends on external circuitry.
Рекомендуется
Industrial Data Acquisition
The PIC24FJ32GP202-I/ML is appropriate for compact industrial data-acquisition equipment requiring 16 MIPS processing, 32 KB of ECC Flash, and 8 KB of RAM. Multiple I2C and UART channels can connect transducers and service interfaces, while SPI supports higher-throughput peripherals and two DMA channels can reduce processor interruption overhead. The 28-QFN 6x6 mm package preserves board area, although exposed-pad layout and thermal management must be implemented according to the manufacturer package drawing.
Рекомендуется
USB-to-Serial Interfaces
The PIC24FJ32GP202-I/ML can implement a compact USB-to-serial bridge when a product needs programmable protocol handling in a 28-QFN 6x6 mm outline. The 32 MHz core and 16 MIPS execution rate support interactive command processing, while UART, SPI, and I2C provide flexible downstream connectivity. The 32 KB ECC Flash is sufficient for firmware and configuration data, and the 8 KB RAM can support short transfer buffers. Confirm the exact USB pin set and device support for the GP202 before routing the connector and power rails.
Рекомендуется
Battery-Operated Embedded Controllers
The PIC24FJ32GP202-I/ML is suitable for battery-operated embedded controllers that balance processing speed with low-power behavior. Its 32 MHz core supports responsive control, while core-independent peripherals can continue selected tasks during sleep and wake the processor through external events. The 32 KB ECC Flash protects program storage and the 8 KB RAM handles control variables and communication buffers. Power architecture remains application-specific, so use the manufacturer electrical characteristics to size regulators, decoupling, and load-switch arrangements around the MCU.
Рекомендуется
Compact Instrument Control Panels
The PIC24FJ32GP202-I/ML works well in compact instruments and control panels where an LCD, keypad, sensor, and communications port must be managed by one microcontroller. Its 8 KB RAM and multiple serial interfaces support display updates, input handling, and external device communication, while the 16 MIPS core avoids offloading simple control tasks. The 28-QFN package helps minimize board area but requires careful exposed-pad layout, local decoupling, and signal-routing discipline in equipment with long cables or noisy analog sections.

Заметки по проектированию
Follow the Microchip land-pattern and exposed-pad guidance for the 28-QFN 6x6 mm package. Place the required input and output decoupling capacitors adjacent to their supply pins, with each capacitor's return path connected to the nearby ground plane. Keep sensitive analog and communication routes away from noisy switching nodes. The exposed pad should use the prescribed copper area and thermal-via pattern to support both electrical return and heat dissipation.
Estimated: with a 3.3 V rail, a 32 MHz core, and an average load of 10 mA, the MCU's rail power is approximately 33 mW using P = 3.3 V × 10 mA. Actual consumption varies with active peripherals, clock gating, and I/O loading, so measure the assembled design across operating and sleep states. Confirm the permitted voltage range and decoupling requirements in the manufacturer electrical-characteristics documentation before selecting the regulator.
Do not assume that every member of the PIC24FJ32GP family has the same USB or peripheral resources. The GP202 device, GP203 device, and related family members can differ in pin availability and dedicated functions even when the core, memory class, and package are similar. Before a substitution, compare the manufacturer pin-description tables, peripheral inventories, interrupt vectors, register definitions, and device configuration bits. A package match alone does not guarantee firmware compatibility.
Route high-speed or noise-sensitive signals away from USB, power-converter, and motor-control switching paths, and provide a continuous ground reference beneath the MCU. Keep I2C and UART signal paths short where practical, use appropriate series damping for externally exposed lines, and observe any external network requirements in the interface datasheets. Where the PCB has both sensitive analog measurement and digital control sections, separate their return paths and keep the analog ground connection strategy deliberate.
Информация о соответствии
The industrial-temperature ordering code does not by itself establish AEC-Q100 qualification. Compliance declarations must be confirmed from the current Microchip product documentation or declarations for the exact ordering code.
