PIC24FJ192GA110T-I/PT - 16-bit MCU, 192KB Flash, 100-TQFP | Microchip
MPN: PIC24FJ192GA110T-I/PT ✓ Hoạt độngPIC24FJ192GA110T-I/PT Tóm tắt
A 16-bit microcontroller (MCU) is a programmable system-on-chip that combines a CPU, memory (Flash and RAM), peripherals, and I/O into a single silicon die. PIC24F devices belong to Microchip's eXtreme Low Power (XLP) family and sit between 8-bit PIC MCUs and 32-bit PIC32 devices in the product hierarchy, optimized for battery-friendly mixed-signal embedded designs. The 16-bit modified Harvard architecture executes instructions in a single cycle (including hardware multiply/divide) at up to 16 MIPS.
Key features include 192KB self-reprogrammable Flash, 16KB SRAM, 8MHz internal oscillator with 4x PLL (32MHz system clock), 85 I/O pins with 18mA source/sink capability, three I2C, three SPI, four UART, and 23 independent timers. The operating voltage range of 2.0V to 3.6V and <100nA standby current suit battery-powered applications. Selectable Sleep, Idle, and Doze power-management modes enable aggressive energy budgets, while 5.5V-tolerant digital inputs simplify interfacing to 3.3V rails.
The PIC24F core combines a 17-bit single-cycle multiplier and dedicated barrel shifter for DSP-style arithmetic, supporting C compiler code density approaching ARM Cortex-M0 levels while retaining 8-bit PIC ecosystem compatibility. Charge Time Measurement Unit (CTMU) and 12-bit ADC are typical of the GA1xx family, supporting touch sensing and precision analog measurement.
Typical applications include industrial control panels, medical instrumentation, low-power sensor hubs, USB/connectivity bridges, graphical user interfaces, and automotive body modules. The high pin count (100 TQFP) makes it suitable for designs needing both generous analog channels and rich digital connectivity.
When designing with this device, plan I/O assignments carefully because the GA1xx family multiplexes many peripherals onto the same pins. Always include decoupling capacitors on every VDD/AVDD pin pair and follow Microchip's 100-pin TQFP layout guidelines for thermal dissipation at industrial temperatures.

Ứng dụng tiêu biểu
PIC24FJ192GA110T-I/PT phù hợp cho 6 Áp dụngs: Industrial Control Panels, Low-Power IoT Sensor Hubs, Medical Instrumentation, Automotive Body Controllers, Graphical User Interface (HMI), USB Connectivity Bridges.
Industrial Control Panels
The PIC24FJ192GA110T-I/PT suits industrial control panels where its 85 GPIO pins drive multiplexed keypads, status LEDs, and seven-segment displays, while the 192KB Flash stores multi-language UI strings and control algorithms. Its 16KB RAM buffers RS-485 sensor traffic from the 4 UARTs at full 16 MIPS, and the industrial -40C to +85C rating handles factory floor thermal stress. The <100nA Sleep current enables battery-backed panel retention during power loss.

Low-Power IoT Sensor Hubs
With <100nA Sleep current and a 2.0V-3.6V operating range, the PIC24FJ192GA110T-I/PT fits battery-powered IoT sensor hubs that wake periodically to read the 12-bit ADC, communicate over SPI to a sensor front-end, and then return to Sleep. The 192KB Flash fits ZigBee/LoRaWAN stack libraries plus application code, while 16KB RAM handles packet buffering. CTMU enables capacitive touch wake-up, extending battery life to multiple years on coin cells.

Ghi chú thiết kế
Place a 100nF ceramic decoupling capacitor within 5mm of every VDD/AVDD pin pair on the PIC24FJ192GA110T-I/PT. According to the Microchip datasheet, the device has 5 VDD pins and 1 AVDD pin; share the same +3.3V rail but isolate AVDD with a ferrite bead for best ADC noise performance. The XLP Sleep current of <100nA requires all unused I/O to be configured as outputs low to eliminate floating-pin leakage.
Use a 4-layer PCB with a dedicated ground plane under the 100-TQFP PIC24FJ192GA110T-I/PT. Route all crystal traces (if used) within 10mm of the OSCI/OSCO pins and guard them with ground vias on both sides. The 12x12mm PT footprint exposes a small thermal pad that should be soldered to a copper pour connected to VSS for best thermal performance during high-MIPS operation.
Do not apply 5V signals to VDD or AVDD - the PIC24FJ192GA110T-I/PT's absolute maximum VDD is 3.6V and 5.5V tolerant only applies to digital inputs, not supply rails. When programming in-circuit via ICSP, ensure PGECx/PGEDx lines have 4.7kohm pull-ups to VDD as recommended by Microchip, otherwise intermittent programming failures occur due to long programming cable capacitance.
The 4 UART channels on the PIC24FJ192GA110T-I/PT operate independently and can run at full baud rates simultaneously. However, when using the Parallel Master Port (PMP) for TFT displays, keep trace lengths under 50mm to avoid setup/hold violations. For EMI-sensitive applications, enable the FRC oscillator with 4x PLL only after firmware initialization to limit inrush current on the +3.3V rail.
