PIC24FJ32GP202-I/SO - 32MHz 32KB Flash MCU | Microchip
MPN: PIC24FJ32GP202-I/SO ✓ Hoạt độngPIC24FJ32GP202-I/SO Tóm tắt
A microcontroller is a programmable system-on-chip that integrates a CPU core, program memory, data memory, peripherals, and I/O into one device. Within the embedded-control hierarchy, the PIC24FJ32GP202 belongs to the Microchip PIC24F family of 16-bit microcontrollers. Its role is to execute firmware, measure external signals, control actuators, and manage communication or power-management tasks in industrial, consumer, and connected products.
The principal specifications are 32 MHz clock speed, 32 KB of ECC Flash, 8 KB of RAM, 16 MIPS performance, and a 2 V to 3.6 V operating range. ECC Flash supports error detection and correction for more reliable code storage, while the 8 KB SRAM supports working state, buffers, and peripheral data. The device provides 21 I/O pins, giving designers sufficient external connectivity for sensors, displays, communications, and discrete controls.
The PIC24FJ32GP2/GU2 family combines conventional GPIO with core-independent peripherals, allowing selected time-critical functions to operate without continuous CPU intervention. The manufacturer describes Full Speed USB 2.0 Host, Device, and OTG capability across the family. Low-power XLP operation and sleep current down to a few hundred nanoseconds' worth of current support battery-oriented and energy-conscious designs where average power matters more than sustained processing throughput.
Typical applications include USB-connected data acquisition, industrial control modules, environmental monitoring, compact human-interface equipment, and low-power embedded products. The 28-pin SOIC package is also convenient for prototypes and designs assembled through conventional leaded-package processes. Engineers should still confirm the exact peripheral mix and pin assignments for the selected device variant in the manufacturer pin-description table.
When planning power, use the 2 V to 3.6 V operating range as the fundamental design constraint. Place decoupling capacitors close to the supply pins, route high-current and sensitive signals away from each other, and use the manufacturer programming and clock documentation when configuring firmware. Avoid treating USB capability as available unless the selected ordering code and its datasheet confirm the required USB pins.
This product page consolidates the manufacturer device information with distributor package details, practical selection guidance, application context, and qualification checks for proposed replacements. It is designed to help engineers identify the correct device quickly while preserving the distinction between an exact ordering variant, a temperature-range variant, and a functionally similar but non-drop-in alternative.

Ứng dụng tiêu biểu
PIC24FJ32GP202-I/SO phù hợp cho 6 Áp dụngs: USB Data Acquisition, Industrial Control Module, Environmental Monitoring, Human Interface Controller, Battery-Powered Sensor Node, General Embedded Control Platform.
USB Data Acquisition
The PIC24FJ32GP202-I/SO fits compact data-acquisition modules that need a 16-bit control engine plus Full Speed USB connectivity. Its 32 MHz operating speed and 16 MIPS throughput provide headroom for sampling, buffering, status processing, and USB protocol handling, while 32 KB of ECC Flash stores application firmware and 8 KB of RAM supports working buffers. The 21 I/O pins can connect sensors, indicators, and configuration controls. Confirm the exact USB-capable pin assignment and transceiver requirements in the manufacturer pin table before committing the board layout.
Được đề xuất
Industrial Control Module
The PIC24FJ32GP202-I/SO is appropriate for industrial control modules combining sensor conditioning, digital logic, and local actuator supervision. The 32-bit? no—the device uses a 16-bit PIC24 RISC core at 32 MHz, providing 16 MIPS while the 32 KB ECC Flash protects stored code from detected or correctable errors. With 21 I/O pins, the controller can connect digital inputs, outputs, and communications. The 2 V to 3.6 V range supports compact low-voltage designs, although isolation, surge protection, and regulatory requirements remain system-level considerations.
Được đề xuất
Environmental Monitoring
The PIC24FJ32GP202-I/SO can coordinate environmental sensors that periodically report temperature, humidity, air quality, or light levels. Its low-power XLP support and very low sleep-current capability are useful when the device spends most of its time waiting between measurements. The 32 KB ECC Flash provides nonvolatile program storage, and 8 KB of RAM accommodates samples and communication staging. Use a regulator with a suitable sleep-current profile and place input filtering close to the sensor interface to avoid adding noise to low-level measurements.
Được đề xuất
Human Interface Controller
The PIC24FJ32GP202-I/SO can manage compact keypads, status indicators, and small displays in embedded user-interface equipment. Its 32 MHz clock and 16 MIPS performance allow debouncing, display updates, menu logic, and communication tasks to coexist, while 21 I/O pins provide practical connectivity for switches and indicators. The 28-pin SOIC package simplifies assembly and repair in leaded-package industrial products. Choose pin multiplexing carefully if the design also requires USB, and validate timing with the peripheral clock configuration specified by the manufacturer.
Được đề xuất
Battery-Powered Sensor Node
The PIC24FJ32GP202-I/SO is suitable for battery-powered sensor nodes where active processing is intermittent. According to Microchip, the GP2/GU2 family supports XLP operation with sleep current down to a few hundred nanoseconds' worth of current while retaining comparator functionality, helping minimize standby demand. The 8 KB RAM and 32 KB ECC Flash are adequate for focused sensing nodes, and the 2 V to 3.6 V operating range supports low-voltage supply designs. Actual battery life depends on sensor load, radio activity, leakage, regulator efficiency, and firmware sleep behavior.
Được đề xuất
General Embedded Control Platform
The PIC24FJ32GP202-I/SO works as a general embedded control platform for products combining digital I/O, timing, communications, and supervisory functions. Core-independent peripherals can handle selected repetitive tasks while the 16-bit core manages application logic, and 32 KB of ECC Flash supports structured firmware with error detection and correction. The 28-pin SOIC package offers a conservative assembly option for prototypes and production hardware using leaded-package processes. Developers should budget pin multiplexing, programming-test access, reset behavior, and supply decoupling into the board design before production release.

Ghi chú thiết kế
Design the supply for the stated 2 V to 3.6 V operating range and place the required bypass capacitors immediately beside the device supply and ground pins. Use the manufacturer pin table and recommended-application circuit to select capacitor values because no single set of external capacitors can be assigned universally without considering clock configuration and peripheral activity. Verify startup, brownout, and sleep-current behavior across the actual load and regulator tolerance.
Route sensitive sensor and communication signals away from high-current switching nodes and provide a short return path beneath the device. Keep programming and debug access reachable, maintain adequate copper around the 28-pin SOIC footprint, and inspect the assembly for lead clearance when the board is densely populated. The 21 I/O pins must be allocated after accounting for power, ground, programming, communications, and any USB functions required by the selected variant.
Do not substitute only on the base device name: the package suffix, temperature suffix, pin count, and functional mix must all match the target PCB. The identified PIC24FJ32GP202-E/SO candidate preserves the 28-pin SOIC format and principal memory and speed ratings, but its temperature-grade ordering suffix differs from the -I/SO device. Confirm both temperature coverage and every multiplexed peripheral before approving it for production.
For battery-powered products, calculate average consumption from the firmware duty cycle rather than the active current alone. Enter the device into its configured low-power state when practical, disable unused peripherals, and account for sensor, regulator, and communications loads. The family's very low sleep-current capability can improve standby performance, but it does not remove the need to evaluate leakage, wake-up timing, and regulator quiescent current.
