PIC24FJ192GA106-E/PT - 192KB Flash 16-bit MCU 64-TQFP
MPN： PIC24FJ192GA106-E/PT ✓ 啟用中PIC24FJ192GA106-E/PT 概覽
This PIC microcontroller belongs to the PIC24FJ family of low-power 16-bit MCUs, a category that bridges the gap between 8-bit PIC16/PIC18 devices and 32-bit PIC32 parts. The PIC24FJ series integrates a wide peripheral set (UART, SPI, I2C, ADC, timers, RTCC, CTMU) on a single die and is intended for low-power (<100 nA standby current), connectivity-rich embedded applications that benefit from multiple serial ports and large memory footprints.
Key features include three I2C, three SPI, four UART serial interfaces, 23 independent timers, a 16-channel 10-bit ADC, three analog comparators with programmable I/O, a hardware real-time clock/calendar (RTCC), and a charge time measurement unit (CTMU) for capacitive touch sensing. The integrated Peripheral Pin Select (PPS) remapping allows most digital peripherals to be assigned to a wide range of I/O pins, easing PCB layout.
Typical applications include industrial control panels, low-power remote sensor nodes, USB/audio bridging bridges, graphic TFT display controllers, and capacitive-touch human-machine interfaces. The wide peripheral mix also suits medical instrumentation and connected consumer appliances.
When designing with this MCU, observe the core decoupling rule: a low-ESR capacitor (such as tantalum) must be placed at the VDDCORE pin to stabilize the on-chip regulator. Programming/debugging is supported by Microchip's MPLAB ICD tools and the in-circuit debugger via dedicated PGx pins. This page synthesizes distributor pricing, drop-in PIC24FJ family alternatives, and practical design notes not found in the manufacturer datasheet.

典型應用
PIC24FJ192GA106-E/PT 適用於 6 應用s: Industrial Control Panels, Low-Power Remote Sensor Nodes, Capacitive Touch HMI Interfaces, Medical Instrumentation, Consumer Appliance Controllers, Audio Bridging and DSP Front-End.
Industrial Control Panels
The PIC24FJ192GA106-E/PT fits industrial control panels thanks to its 192 KB Flash for HMI firmware, 16 KB RAM for display frame buffers, and four UART ports for multi-drop RS-485 networks. The 32 MHz CPU can refresh character or small TFT LCDs while simultaneously managing Modbus RTU traffic. The -40C to +125C extended temperature range (E suffix) covers unheated cabinet installations, and the Peripheral Pin Select (PPS) feature lets PCB designers reroute UART, SPI, and I2C signals to ease EMC-aware layout.
推薦
Low-Power Remote Sensor Nodes
For battery-powered wireless sensor nodes, the PIC24FJ192GA106-E/PT provides <100 nA standby current in deep-sleep mode while retaining RAM, allowing fast wake-and-transmit cycles. The 16 KB RAM accommodates sensor data buffering between radio transmissions, and the integrated 10-bit ADC with 16 input channels supports multi-sensor acquisition. The three SPI ports can drive Sub-GHz transceivers, external sensors, and flash memory without external multiplexer ICs.
推薦
Capacitive Touch HMI Interfaces
The integrated Charge Time Measurement Unit (CTMU) makes PIC24FJ192GA106-E/PT well suited for capacitive-touch human-machine interfaces, supporting buttons, sliders, and proximity sensors without an external touch controller. The 16 KB RAM can hold touch-scanning state machines and debounce tables, and the three I2C ports let the design add a TFT display driver without consuming SPI resources. PPS reassignment allows the touch channels to be remapped to alternate I/O pins if PCB layout changes mid-design.
推薦
Medical Instrumentation
In medical instrumentation such as portable pulse oximeters, glucometers, and patient-side monitors, the PIC24FJ192GA106-E/PT delivers deterministic 16-bit performance for signal conditioning. The 16-channel 10-bit ADC handles multiple sensor inputs, and the four UARTs split communication between a host processor, an SPI display, and an optional Bluetooth or Wi-Fi module. The hardware RTCC supports time-stamped event logging for clinical audit trails.
推薦
Consumer Appliance Controllers
PIC24FJ192GA106-E/PT serves as the main controller in washing machines, dishwashers, induction cooktops, and HVAC thermostats because it integrates 192 KB of firmware space for state machines plus UI logic. The 23 independent timers drive PWM outputs for motor control, valve sequencing, and zero-cross detection. The wide 2.0 V to 3.6 V supply range supports both 3.3 V and battery-backed 3 V designs.
推薦
Audio Bridging and DSP Front-End
The PIC24FJ192GA106-E/PT's 16 MIPS performance and 16 KB RAM allow real-time audio sample routing and basic DSP filtering in USB audio adapters, Bluetooth speaker docks, and hearing-aid programming interfaces. The SPI ports drive external audio codecs, while the integrated RTCC timestamps recording sessions. PPS gives flexibility when routing I2S-style signals alongside the three I2C ports used for codec configuration.

- Extended -40C to +125C temperature grade (對比PIC24FJ192GA106-I/PT)

設計說明
A low-ESR capacitor (such as 10 uF tantalum or ceramic) must be connected to the VDDCORE pin to maintain the stability of the on-chip core voltage regulator. Omitting this capacitor or using a high-ESR part can lead to brown-outs and erratic behavior at high CPU loads or low temperatures. Place the capacitor physically within 5 mm of the VDDCORE pin and route a wide ground pour directly back to the nearest VSS pad.
Use the Peripheral Pin Select (PPS) feature to remap digital peripherals (UART, SPI, I2C) to any of the remappable I/O pins after laying out the PCB. This avoids hard-wiring peripheral functions to fixed pins and gives layout engineers freedom to group signals for EMC compliance. Always lock the PPS configuration in firmware before any communication peripheral is enabled.
Do not drive I/O pins above VDD + 0.3 V or below VSS - 0.3 V; the absolute maximum ratings are easily exceeded when interfacing 5 V logic. Use external level shifters or resistive dividers when connecting to 5 V peripherals. Also ensure the MCLR reset pin has a proper 10 kohm pull-up and a 100 nF decoupling capacitor directly at the pin to prevent unintended resets in noisy environments.
