PIC24FJ16GA002-I/SS - 32MHz 16KB Flash Microcontroller | Microchip
料号： PIC24FJ16GA002-I/SS ✓ 量产中PIC24FJ16GA002-I/SS 概述
A microcontroller is a complete programmable control system integrated onto one semiconductor device. The PIC24F family combines a 16-bit RISC core, Flash memory, SRAM, timers, communication peripherals, and general-purpose I/O in a single package. This allows a design to replace several discrete logic and memory components while providing deterministic program execution, interrupt handling, and efficient peripheral integration. PIC24F devices are commonly used where compact embedded intelligence, low power consumption, and a broad peripheral set are required.
Key device attributes include 16 KB of Flash organized as 5.5K by 24 bits, 4096 bytes of SRAM, 21 I/O pins, a 32 MHz system clock, and 16 MIPS performance at 3.3 V. A 17-by-17 hardware multiplier supports efficient single-cycle multiplication operations, while basic Code Guard security provides a hardware mechanism for protecting program code. These characteristics make the PIC24FJ16GA002-I/SS suitable for control loops, lighting management, and compact sensor-driven products.
The PIC24F CPU architecture uses a Harvard-oriented design with separate program and data memory spaces. Flash memory permits in-circuit reprogramming and field firmware updates, and the SRAM area can hold working variables, stack data, and peripheral buffers. The MCU also integrates conventional embedded resources such as timers, serial interfaces, interrupt control, and port multiplexing, allowing firmware to coordinate multiple time-sensitive tasks without adding external logic.
Typical applications include smart LED lighting modules, occupancy and environmental controllers, compact motor-control helpers, programmable logic controllers, industrial sensor nodes, and low-power consumer products. Its 28-pin SSOP footprint is useful where a through-hole package is unnecessary and a surface-mount assembly can reduce board area. The industrial-temperature ordering code supports deployments across a broad range of commercial and industrial ambient conditions.
For new layouts, use the pin-description table and recommended decoupling arrangement in the Microchip datasheet. Confirm the exact oscillator configuration, I/O multiplexing, programming pins, and peripheral assignments before layout release because the 21 I/O pins are shared with internal functions. Verify the maximum peripheral and operating-frequency conditions against the intended supply voltage.

典型应用
PIC24FJ16GA002-I/SS 适用于 6 应用s: Smart LED Lighting Control, Industrial Sensor Node, Occupancy and Environment Controller, Compact Programmable Logic Controller, Battery-Powered Data Logger, Small Motor and Auxiliary Control Module.
Smart LED Lighting Control
The PIC24FJ16GA002-I/SS fits smart lighting modules that require local switching, dimming, and communication logic. Its 32 MHz core provides up to 16 MIPS at 3.3 V, while 21 I/O pins can connect LED drive-control signals, buttons, occupancy sensors, and serial interfaces. The 16 KB Flash stores control tables and firmware, and the 4096-byte RAM supports state machines and communication buffers. Place the MCU near the LED driver control inputs and use the Microchip pin-description table when assigning timer outputs or serial functions.
推荐
Industrial Sensor Node
The PIC24FJ16GA002-I/SS can serve as the control hub in a compact industrial sensor node that aggregates analog measurements, digital sensor inputs, and periodic communications. The 16-bit RISC core handles filtering and control logic at up to 16 MIPS at 3.3 V, while 4096 bytes of RAM accommodates working state and protocol buffers. Twenty-one GPIO pins support sensors, status indicators, and alarms. For industrial deployment, verify the ordering variant's temperature rating and use the manufacturer recommended decoupling and external oscillator guidance.
推荐
Occupancy and Environment Controller
The PIC24FJ16GA002-I/SS is appropriate for occupancy, temperature, and lighting controllers that combine low-power sensing with configurable output behavior. Its PIC24F eXtreme low-power architecture supports duty-cycled operation, while the 32 MHz processor can execute debouncing, filtering, and adaptive-control algorithms. The 21 available I/O pins connect passive sensors, switches, and relay or transistor drive stages. Confirm that every selected pin is not committed to programming or oscillator functions and validate the low-power current budget with the final firmware duty cycle.
推荐
Compact Programmable Logic Controller
The PIC24FJ16GA002-I/SS can implement compact PLC-like sequencing, input scanning, timers, and output control where a full-size programmable controller would be excessive. Sixteen MIPS at 3.3 V provides ample instruction throughput for deterministic state-machine logic, and 16 KB of Flash holds the application program. The 21 GPIO pins can be assigned to field inputs and outputs. Build a small input-protection network, respect per-pin electrical limits, and check the required startup behavior against the Microchip datasheet.
推荐
Battery-Powered Data Logger
The PIC24FJ16GA002-I/SS is suitable for a battery-powered logger that samples sensors, stores event data, and wakes periodically for radio or serial reporting. The low-power PIC24F architecture reduces active-system energy, while the 4096-byte RAM provides a working buffer for batches of measurements and the 16 KB Flash stores firmware and configuration. Twenty-one I/O pins support sensor selection, wake sources, and status feedback. Validate sleep-mode current, analog-peripheral behavior, and write endurance at the product level rather than relying on nominal processor specifications alone.
推荐
Small Motor and Auxiliary Control Module
The PIC24FJ16GA002-I/SS can coordinate a small motor, solenoid, or stepped actuator in a compact auxiliary-control module. Its 17-by-17 hardware multiplier supports efficient arithmetic in motion and timing routines, and the 32 MHz core can manage pulse timing, position counting, and fault handling. Twenty-one GPIO pins provide interface capacity for limit switches, encoders, and driver-control signals. Use timer-capable pins for deterministic waveforms and follow the Microchip electrical limits for motor transients and supply currents.

- Closest identified ordering alternative retains core resources （对比 PIC24FJ16GA002T-I/SS)

设计说明
Assign the PCB footprint from the 28-pin SSOP drawing in the Microchip datasheet and place decoupling capacitors close to the device's VDD and VSS pins. Route sensitive oscillator and programming-related connections away from fast-switching nodes. The MCU has only 21 general-purpose I/O pins because several package leads serve internal functions, so freeze pin multiplexing against the application firmware before routing the board.
Design the 3.3 V supply to remain within the device's specified operating limits at the maximum 32 MHz clock condition. Use the manufacturer recommended supply ramp and decoupling arrangement rather than relying on general regulator practice alone. If an external oscillator is used, confirm its startup, drive level, and stability requirements in the Microchip documentation. Separate noisy loads from the MCU rail to reduce supply-transient risk.
Do not treat a same-package PIC24FJ16GA member as an automatic substitution. Check Flash size, RAM size, peripheral assignments, pin multiplexing, boot or programming behavior, and the required temperature or automotive qualification. PIC24FJ16GA002T-I/SS is the closest identified ordering alternative, while other family members can differ in memory capacity. Confirm the exact alternate in the manufacturer cross-reference tool before releasing production artwork.
Keep the 32 MHz clock path short and isolated from sensitive analog or sensor inputs, and follow the Microchip guidance for grounding around the oscillator pins. Where the application combines switching power circuitry with sensor inputs, provide a clean return path and place input protection close to the connector. Use the pin-description table to identify oscillator, programming, and reset functions so those leads are not accidentally assigned as ordinary GPIO.
