PIC24FJ192GA110-E/PT Overview
A PIC24F microcontroller is a 16-bit modified-Harvard RISC MCU designed by Microchip for embedded control applications that demand low power, ample memory, and rich connectivity. Within the broader taxonomy it sits between 8-bit PIC MCUs and 32-bit PIC32 devices, balancing code density, peripheral integration, and cost. PIC24F parts share the PIC24 instruction set with 16-bit data paths and execute one instruction per two clock cycles, delivering up to 16 MIPS at 32 MHz while drawing less than 100 nA in standby.
Key features include Peripheral Pin Select (PPS) for flexible I/O mapping, three I2C, three SPI, and four UART serial interfaces, twenty-three independent timers, a 16-channel 10-bit ADC with 500 ksps throughput, hardware RTCC, and selectable power management modes including Sleep, Idle, and Doze. The CTMU peripheral supports capacitive touch sensing, while Parallel Master Port and EPMP-like external bus options address larger memory or graphics subsystems. Operating voltage spans 2.0 V to 3.6 V with 5.5 V-tolerant digital inputs for mixed-voltage designs.
The 100-pin TQFP package exposes up to 85 I/O pins and supports JTAG/ICSP in-system programming plus self-programmability under software control. The architectural sweet spot is battery-powered and connectivity-rich embedded applications where on-chip RAM (16 KB) doubles compared with PIC24FJ64 devices in the same pinout, enabling larger buffers, audio samples, or protocol stacks.
Typical applications include industrial automation controllers, low-power sensor hubs, HMI/graphical displays, USB device-class peripherals, and consumer devices requiring UART/SPI/I2C bridging. The high RAM/flash ratio suits protocol translation, audio streaming, and lightweight graphics rendering.
When designing, take advantage of PPS to remap peripherals to available pins and route analog signals to dedicated ANx pins to minimize digital noise coupling. Plan power sequencing and decoupling per the family reference manual.

Typical Applications
PIC24FJ192GA110-E/PT is suitable for 7 applications: Industrial Automation Controllers, Low-Power Sensor Hubs, HMI and Graphical Displays, USB Device-Class Peripherals, Audio and Voice Processing, Consumer Connectivity Devices, Automotive Body Electronics.
Industrial Automation Controllers
The PIC24FJ192GA110-E/PT fits industrial automation controllers with 192 KB flash and 16 KB RAM, which provide headroom for ladder-logic interpreters, Modbus RTU stacks, and PID control loops. The 4 UARTs handle RS-232/RS-485 multi-drop networks, while 3 SPI and 3 I2C interfaces drive sensor front-ends and HMI displays. The -40C to +125C extended temperature grade meets factory-floor thermal demands, and PPS allows flexible PCB routing of peripherals into mixed connector pinouts.
Recommended
Low-Power Sensor Hubs
For battery-powered wireless sensor hubs, the PIC24FJ192GA110-E/PT draws under 100 nA in deep Sleep, waking via RTCC or external interrupts to service sensor reads and radio packets. The 16 KB RAM accommodates protocol buffers for Zigbee, LoRa, or Bluetooth Low Energy, while 192 KB flash stores multiple protocol stacks and OTA update images. PPS routes I2C sensors, SPI radios, and UART debug ports without pin conflicts across different sensor boards.
Recommended
HMI and Graphical Displays
The PIC24FJ192GA110-E/PT drives character or small graphical LCDs via PMP/EPMP-style external bus and CTMU capacitive touch sensing, making it a strong host for HMI panels. The 192 KB flash stores multi-language menus, animations, and graphics tables, while 16 KB RAM serves as framebuffer for monochrome or grayscale displays. PPS allows direct mapping of PMP data lines to available ports, simplifying PCB layout for slim HMI enclosures.
Recommended
USB Device-Class Peripherals
USB device-class peripherals such as HID input devices, CDC virtual COM ports, and MSD card readers benefit from the PIC24FJ192GA110-E/PT's 4 UART, 3 SPI, and full-speed USB-friendly PIC24F core. The 16 KB RAM buffers USB packets and protocol stacks, while 192 KB flash fits composite USB descriptors and application code. The 5.5 V-tolerant digital inputs tolerate USB bus-powered 5 V signal levels when properly attenuated.
Recommended
Audio and Voice Processing
Voice playback, audio effects, and speech-recognition front-ends benefit from the PIC24FJ192GA110-E/PT's 16 KB RAM, which holds several seconds of ADPCM-encoded audio at typical sample rates. The 192 KB flash stores lookup tables, codecs, and phrase libraries, while the 4 UARTs drive external DACs or audio CODECs. PPS routes I2S-style clocks to available pins, and the 32 MHz / 16 MIPS core sustains real-time DSP for lightweight filtering and FFT.
Recommended
Consumer Connectivity Devices
Smart-home gateways, wearable companions, and BLE-MCU bridges run on the PIC24FJ192GA110-E/PT thanks to its multi-protocol serial interfaces and ample memory. The 4 UARTs handle WiFi/BLE module control and AT-command parsing, while SPI and I2C drive sensors and displays. Sub-100 nA Sleep current extends battery life in standby, and the -40C to +125C extended grade supports wearables and outdoor IoT enclosures.
Recommended
Automotive Body Electronics
Automotive body controllers and lighting modules benefit from the PIC24FJ192GA110-E/PT's extended -40C to +125C temperature grade, 5.5 V-tolerant digital inputs, and rich timer set. The 4 UARTs drive LIN or K-Line transceivers, while CAN is handled via external controllers tied to SPI. PPS simplifies pinout adaptation when migrating between different vehicle harness connectors, and 192 KB flash stores bootloaders plus application code.

Key Differentiators
- Higher flash and RAM in same 100-pin TQFP package (vs PIC24FJ128GA110-I/PT)
- Extended -40C to +125C temperature grade in identical footprint (vs PIC24FJ192GA110-I/PT)
- Peripheral Pin Select (PPS) for layout flexibility (vs PIC24FJ128GA106-I/PT (64-pin TQFP variant))
Design Notes
Estimated: at VDD=3.3 V, the PIC24FJ192GA110-E/PT draws approximately 15 to 25 mA at 32 MHz active with all peripherals on, falling to under 100 nA in deep Sleep with RTCC off. For battery-powered designs, gate peripheral power via Load Switches or I/O port-controlled regulators, and use Sleep + RTCC scheduling rather than Idle for maximum battery life. Decouple VDD/AVDD with 100 nF ceramic plus 10 uF bulk per the Microchip PIC24F reference manual design checklist.
Route the 100-pin TQFP (12x12 mm) on a 4-layer PCB with continuous ground plane under the device and a star-grounded analog section for AVDD/AVSS. Keep the 32.768 kHz secondary oscillator traces short and guarded by ground to minimize RTCC drift. Place bulk capacitors within 10 mm of VDD pins; place 100 nF bypass caps within 2 mm of every VDD pin. Expose MCLR to a 10 kohm pull-up and a 100 nF cap for clean reset behavior.
Group PPS-mapped digital peripherals on one side of the device to simplify pinout reuse across PIC24FJ128 and PIC24FJ192 variants. Keep ADC ANx pins separated from PWM and high-frequency digital lines by a ground guard or by physical separation to preserve ADC SNR. When using EPMP-style external bus, place the memory device close to the PIC24FJ192GA110-E/PT and add series damping resistors if the bus exceeds 50 MHz equivalent switching rate.
Do not exceed 3.6 V on VDD, or 5.5 V on 5.5 V-tolerant digital I/O pins. Always unlock PPS via the IOLOCK sequence before remapping peripherals; locked PPS causes silent peripheral failures on first prototype. Verify AVDD and VDD power up within 10 ms of each other; failure to do so can latch the ADC into an undefined state. Use the Microchip MCC or Harmony configurator to avoid configuration register mistakes.
For SPI bus runs above 10 MHz, place 22 to 33 ohm series resistors near the driver pins to dampen ringing on long PCB traces. I2C lines exceeding 100 mm benefit from 4.7 kohm pull-ups and a 100 pF to 470 pF speed-up cap on standard-mode segments. Route USB differential pairs (D+/D-) with 90 ohm differential impedance when the design includes the on-chip USB peripheral or external USB bridge.
