PIC24FJ48GA002-I/SO Übersicht
Background: a PIC24F is a 16-bit RISC microcontroller in the Microchip PIC family that uses a modified Harvard architecture with separate program and data paths and a 16-bit-wide datapath. PIC24F devices target low-power general-purpose embedded control, sitting below dsPIC33 (DSP-extended) parts and above 8-bit PIC16/PIC18 in compute, RAM, and peripheral capability. They are commonly selected for cost-sensitive 3.3 V systems needing higher performance than 8-bit MCUs but not the complexity of 32-bit ARM Cortex-M parts.
Key features include hardware single-cycle 17x17 multiplication, a 32-bit/16-bit hardware divider, C-compiler-optimized instruction set, a real-time clock calendar (RTCC), five 16-bit timers, and an internal 8 MHz oscillator with PLL. The integrated nanoWatt technology manages idle, sleep, and deep-sleep modes for power-sensitive applications. JTAG and ICSP in-circuit debugging are supported across the family.
Technical depth: the PIC24FJ48GA002 shares its peripheral set and pinout with other PIC24FJXXXGA0XX family members (28-pin and 44-pin variants). The 'GA0' designator indicates the peripheral line; 'I' denotes the industrial temperature grade (-40C to +85C) and '/SO' is the 28-pin SOIC wide package. The architecture separates Flash program memory from RAM via dual-bus Harvard paths, allowing simultaneous instruction fetch and data access.
Typical applications include industrial control panels, sensor signal conditioning, low-power IoT edge nodes, USB/serial bridging, and human-machine interface (HMI) subsystems. The Explorer 16/32 development board supports this part via a Processor Plug-In Module (PIM).
Design consideration: the 28-pin SOIC wide footprint offers easy hand-soldering during prototyping and accommodates all 21 I/O lines. Note that the upper Flash address region is reserved for bootloader use; refer to the device family datasheet section 5 for memory mapping details.

Typische Anwendungen
PIC24FJ48GA002-I/SO ist geeignet für 6 Anwendungs: Industrial Control Panels, Sensor Signal Conditioning Hubs, Low-Power IoT Edge Nodes, USB-Serial Bridge / Protocol Converter, Human-Machine Interface (HMI) Subsystems, Battery Management for Portable Devices.
Industrial Control Panels
The PIC24FJ48GA002-I/SO fits industrial control panels because its 16 MIPS core and 28-pin SOIC wide footprint support multi-drop RS-485 links, discrete digital I/O, and keypad scanning in a single IC. The 21 GPIO lines comfortably drive 4x4 matrix keypads plus 7-segment display multiplex without external I/O expanders. The 10-bit A/D with up to 10 channels reads 4-20 mA loop sensors via external burden resistors, while the two UART modules handle RS-232/RS-485 transceivers for PLC backplane communication. The 48 KB Flash accommodates menu structures, PID loop code, and a bootloader for field firmware updates via UART, and the -40C to +85C industrial grade survives unheated cabinet environments. NanoWatt sleep modes drop quiescent current under 1 uA, suiting battery-backed panels that retain state during power loss.

Sensor Signal Conditioning Hubs
The PIC24FJ48GA002-I/SO is a strong fit for sensor signal conditioning because the 10-bit A/D converter combined with two SPI and one I2C port lets it read multiple digital sensors (accelerometers, temperature, pressure) and analog transducers simultaneously. The 16 MIPS throughput executes oversampling and averaging filters in real time at 1 kHz sample rates, smoothing noisy sensor readings before forwarding over UART. The 8 KB RAM supports 1024-sample circular buffers per channel for burst capture, and 48 KB Flash accommodates sensor calibration tables plus protocol stacks. The 2.0 V to 3.6 V supply range allows direct operation from Li-ion packs with simple LDO regulation. This part is commonly paired with MEMS sensors and 4-20 mA loop conditioning front-ends for industrial instrumentation.
Empfohlen
Low-Power IoT Edge Nodes
The PIC24FJ48GA002-I/SO enables low-power IoT edge nodes because its nanoWatt technology manages Idle, Sleep, and Deep-Sleep modes while an RTCC keeps wall-clock time on a few microamperes. Wake-on-RTCC, watchdog, or external interrupt sources let the MCU spend most of its life in Deep-Sleep, extending battery life to multi-year runtime on 2x AA cells. The 16 MIPS core wakes within microseconds to service sensor reads and transmit over UART-attached radios or SPI-attached transceivers. The 8 KB RAM buffers small telemetry packets without external memory. The 28-pin SOIC package is hand-solderable for prototype runs and reflows cleanly for production. Typical pairings include Sub-GHz radio modules (e.g., MRF89XA), BLE bridges, and LoRaWAN modems.
Empfohlen
USB-Serial Bridge / Protocol Converter
The PIC24FJ48GA002-I/SO serves as a USB-to-UART, USB-to-I2C, or USB-to-SPI bridge because its two UART modules, two SPI, and I2C bus cover most common industrial and embedded protocols. Running at 16 MIPS, the MCU performs transparent protocol conversion with no perceptible latency for 115200 baud serial streams, and the 48 KB Flash holds USB HID or CDC class descriptors alongside bridge firmware. A common configuration is PIC24FJ48GA002-I/SO + MCP2200 USB-UART, or pairing the PIC24FJ64GB002-I/SO variant when USB OTG is needed on-chip. The 28-pin SOIC wide footprint is footprint-compatible with common USB-Serial module pinouts, simplifying retrofit designs and adapter cables.
Empfohlen
Human-Machine Interface (HMI) Subsystems
The PIC24FJ48GA002-I/SO drives HMI subsystems because its 21 GPIO lines, 5 timers, and 16 MIPS throughput support character LCDs, LED matrices, rotary encoders, and capacitive touch buttons in a single IC. The hardware 17x17 multiplier and 32/16 divider execute menu navigation and value-processing math without taxing the CPU. The 48 KB Flash stores multilingual menu strings and bitmap fonts; 8 KB RAM handles display buffers up to 4x40 character panels. Pairing with an I2C GPIO expander (MCP23008) extends the panel to 40+ keys and 32 LEDs without changing the main MCU. The wide SOIC-28 footprint is ideal for hand-rework of prototype HMIs in low-volume industrial products.
Empfohlen
Battery Management for Portable Devices
The PIC24FJ48GA002-I/SO powers battery management subsystems in portable medical and handheld industrial tools because the 10-bit A/D reads battery voltage, charge current, and thermistor inputs with adequate precision for Li-ion/polymer packs. The 2.0 V to 3.6 V supply allows direct operation from a single Li-ion cell without boost regulation. The RTCC timestamps charge events for accurate fuel gauging, and the nanoWatt sleep modes keep quiescent draw below 1 uA for shelf storage. The 48 KB Flash hosts the charging state machine plus logging memory, while 8 KB RAM buffers Coulomb-count samples. The wide operating temperature range covers both cold outdoor and warm in-pocket conditions encountered by handheld devices.

Wichtigste Unterscheidungsmerkmale
- Wide SOIC-28 hand-solderable footprint with 21 GPIO (vs. PIC24FJ48GA002-I/SP (SPDIP-28))
- 48 KB Flash with full 8 KB RAM at sub-$1.30 unit cost (vs. PIC24FJ64GA002-I/SO)
- Industrial temperature grade with verified active lifecycle status (vs. PIC24FJ16GA002-I/SO (smaller Flash))
Designhinweise
Estimated: at VDD = 3.3 V, 16 MIPS active CPU draw is around 15-20 mA from the PIC24FJ48GA002-I/SO typical current spec; add 5-10 mA for peripherals. Use a 100 nF decoupling capacitor within 5 mm of VDD pin 20 and a 10 uF bulk cap on the supply rail. Deep-Sleep mode drops current below 1 uA per the nanoWatt spec, but wake-up source selection (RTCC vs external interrupt) determines suitability for battery-powered designs.
Place the 28-pin SOIC wide footprint on a 1.27 mm (50 mil) pitch land pattern with exposed pads on the thermal pads left floating. Keep the 32.768 kHz crystal or external clock traces within 5 mm of pins 9-10 and shield them with a ground guard ring to avoid noise injection into the analog A/D references. Separate analog (AN0-AN9) traces from switching power and PWM lines by at least 3 mm to preserve ADC SNR.
Do not exceed 3.6 V on VDD - PIC24FJ48GA002-I/SO is NOT 5 V tolerant. Always configure unused I/O pins as outputs with low level to minimize current draw in Sleep mode. When migrating firmware from PIC24FJ64GA002-I/SO, remember the 64 KB device has a different config-word address layout for the bootloader region; check section 5 of the family datasheet before reuse.
Compliance-Informationen
RoHS and lead-free compliant per Microchip product page. Not AEC-Q100 qualified - choose the PIC24FJ48GA002-E/SO extended-temperature variant for harsh-environment designs.
