PIC24FJ192GA110-I/PT Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a wide range of peripherals (timers, communication controllers, ADCs, GPIO) on one die. PIC24F microcontrollers sit in Microchip's 16-bit MCU hierarchy above the 8-bit PIC16/PIC18 families and below the 32-bit PIC32MX/dsPIC33 parts. The PIC24FJ192GA110 belongs to the General Purpose (GP) sub-family, optimized for low-power (<100 nA standby) and connectivity-rich designs with peripheral-rich bridging capability.
Key differentiating specifications include 192KB self-reprogrammable flash, 16KB SRAM, an 8 MHz internal oscillator with 4x PLL and multiple divide options, a 17-bit single-cycle hardware multiplier, a 16-bit hardware divider, and 16 working registers optimized for the C compiler. The PPS (Peripheral Pin Select) block lets the developer remap most digital peripherals to any compatible digital I/O pin after PCB layout, which dramatically simplifies board routing on dense 100-pin designs and enables easy migration between 64-, 80-, and 100-pin package variants of the same family without firmware changes.
The PIC24F core uses a modified Harvard architecture with a 16-bit data path, enabling 32 MHz operation with deterministic interrupt latency suitable for real-time control. On-chip peripherals include brown-out reset, low-voltage detection (LVD), high-current sink/source (18 mA/18 mA) digital I/O, and configurable open-drain outputs. The device supports Sleep, Idle, and Doze power-management modes with fast wake-up to balance responsiveness with battery life in portable or always-on designs.
Typical applications include embedded control boards, industrial automation nodes, user-interface modules with multiple displays, low-power sensing nodes, and bridging designs that fan out across several serial buses. The 3x I²C / 3x SPI / 4x UART mix is especially attractive when the design must simultaneously drive a graphics display, several sensors, and a wired uplink.
When designing with this MCU, observe the 2.0V to 3.6V supply range, leverage 5.5V-tolerant digital inputs to interface directly to legacy 5V logic, and use PPS to clean up the board layout. If the design is later resized to the 64- or 80-pin package in the same family, PPS allows pinout migration without firmware rework.

Typical Applications
PIC24FJ192GA110-I/PT is suitable for 6 applications: Industrial Automation Controllers, Low-Power IoT Sensor Hubs, Human-Machine Interface (HMI) Modules, Medical Monitoring Devices, Automotive Body and Comfort Modules, Audio and Consumer Interface Boards.
Industrial Automation Controllers
The PIC24FJ192GA110-I/PT fits industrial control boards thanks to its 32 MIPS performance, 192 KB flash for protocol stacks, and 100-pin TQFP giving plenty of GPIO for motor and sensor I/O. Its 5.5 V-tolerant digital inputs interface directly to 24 V-conditioned industrial logic via simple resistor dividers, while 18 mA source/sink drive lets it switch relays, optocouplers, and indicator LEDs without external buffers. The 3x I²C, 3x SPI, and 4x UART mix handles multi-bus field networks (Modbus RTU over UART, sensor I/O over I²C/SPI), and Peripheral Pin Select simplifies board layout when the design later moves between 64-, 80-, and 100-pin package options. Sleep current under 100 nA keeps standby battery drain minimal in always-on controllers.
Recommended
Low-Power IoT Sensor Hubs
The PIC24FJ192GA110-I/PT is ideal for battery-powered IoT sensor hubs where <100 nA Sleep current extends runtime to years on a single cell. Its 16 KB SRAM buffers multiple sensor samples before transmission, while 192 KB flash stores the full sensor-fusion and wireless-protocol stack. The PIC24F core's Sleep / Idle / Doze modes let the firmware wake only on interrupt, sample, transmit over UART/SPI, and return to Sleep with deterministic latency. 5.5 V-tolerant inputs accept signals from a wide range of analog front-ends, and the 23 timers cover sampling-rate scheduling, watchdog, and PWM tasks. Combined with PPS, the layout remains clean even with dense sensor boards.
Recommended
Human-Machine Interface (HMI) Modules
The PIC24FJ192GA110-I/PT drives small HMI panels with TFT displays, keypads, and status LEDs, leveraging 32 MIPS to refresh color displays and debounce keys in real time. Its 4x UART drives multiple downstream RS-485/RS-232 links, while 3x SPI connects to TFT controllers, touch controllers, and external flash. 16 KB SRAM holds display frame buffers for partial-update strategies, and 192 KB flash holds GUI bitmaps and font tables. PPS remaps peripheral functions so the same firmware works across the 64-, 80-, and 100-pin package options as panel complexity grows, reducing BOM variants in HMI product families.
Recommended
Medical Monitoring Devices
The PIC24FJ192GA110-I/PT suits patient-monitoring peripherals such as pulse-oximeter front-ends, infusion-pump keypads, and bedside vital-sign displays where deterministic 16-bit processing and reliability are required. Its 32 MIPS core processes sensor data and filters in real time; 192 KB flash stores calibration tables and unit firmware; and 16 KB SRAM holds short rolling buffers of waveform data. Low Sleep current lets battery-backed units survive storage and transport without draining the cell, and 5.5 V-tolerant digital inputs accept legacy medical-instrument signaling levels. PPS simplifies PCB layout when the design is scaled up or down across pin-count variants.
Recommended
Automotive Body and Comfort Modules
The PIC24FJ192GA110-I/PT, in its -E (extended temperature) variant, fits non-safety automotive body modules such as seat controllers, HVAC panels, and lighting drivers that benefit from rich connectivity and low standby drain. Its 100-pin TQFP supplies ample GPIO for multiple LIN/CAN-style UART links (via external transceivers), PWM-driven LED strings, and switch inputs. The PIC24F Sleep/Idle/Doze architecture supports key-off quiescent currents below 100 nA, helping meet automotive parasitic drain budgets. PPS makes it easy to reassign peripheral pins during layout without firmware rework, and the 5.5 V-tolerant digital inputs survive 12 V load-dump transients via external clamping.
Recommended
Audio and Consumer Interface Boards
The PIC24FJ192GA110-I/PT is used in consumer audio front panels, headphone amplifiers, and docking-station controllers where it bridges multiple digital audio buses and front-panel buttons. Its 3x I²C controls DAC/ADC volume and channel-mux chips, 3x SPI drives display controllers and flash storage, and 4x UART services Bluetooth/Wi-Fi modules and firmware-update links. 192 KB flash holds UI state machines and DSP configuration tables, while 16 KB SRAM holds display strings and audio routing maps. PPS permits flexible pinout, enabling PCB reuse across product variants with different connector placements.

Key Differentiators
- Larger flash with same die and pinout (vs PIC24FJ128GA010-I/PT)
- Extended-temperature option exists on same silicon (vs PIC24FJ192GA110-E/PT)
- Lower-voltage and 5 V-tolerant inputs (vs STM32F103VCT6)
- PPS pin-remapping flexibility (vs PIC24FJ128GA010-I/PT)
Design Notes
PIC24F core Vdd range is 2.0 V to 3.6 V. Place a 10 uF bulk capacitor near Vdd and a 0.1 uF decoupling cap on every Vdd/Vss pair to handle the transient when peripherals wake from Sleep. AVdd, if used by the ADC, must be tied to Vdd and bypassed with its own 10 uF + 0.1 uF pair per datasheet 39747G. If the design also powers from 5 V, route 5 V-tolerant inputs through series resistors so the digital input current stays within spec.
Route ICSP pins (PGECx/PGEDx) to a debug header that is reachable without disturbing the rest of the circuit. The 100-pin TQFP (12x12) leaves only a 0.4 mm pitch; use 0.2 mm/8 mil traces and 0.2 mm-wide clearances with a 4-layer stack-up if possible. Keep crystal traces short and guard them with a ground pour to minimize EMI; the internal 8 MHz oscillator with 4x PLL is usually adequate for non-USB designs and removes the need for an external crystal.
PPS is configured per peripheral instance at runtime; if the firmware changes, the same physical pin may serve a different function. Always verify the PPS lock/unlock sequence (PPSLOCK bit) in the startup code and never re-enter the unlock sequence from interrupt context. Brown-out reset must be enabled for production firmware; without it, a momentary Vdd dip can leave the CPU running with corrupted flash read state.
Use Peripheral Pin Select to keep high-speed peripherals (SPI clock, UART TX) on pins near the package edge so traces do not cross the BGA-style inner rows of the TQFP. If the design migrates between 64-, 80-, and 100-pin package variants of the GA110 family, leave PPS-unassigned flexibility in the schematic so the same firmware binary can drive all three layouts with only the configuration table changed. Avoid loading the ICSP pins with external pull-ups or bus devices stronger than 100 uA during programming.
Compliance Information
RoHS compliant per Microchip product page; not AEC-Q100 qualified (use E-grade variants for extended temperature; AEC-Q100 PIC variants are separate parts). Lead-free and halogen-free per Microchip material declarations.
