PIC24FJ192GA110-E/PT - 16-bit 192KB Flash MCU | Microchip
MPN: PIC24FJ192GA110-E/PT ✓ Hoạt độngPIC24FJ192GA110-E/PT Tóm tắt
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.

Ghi chú thiết kế
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.
