PIC24FJ64GA110T-I/PT Visão geral
A microcontroller (MCU) is a single-chip computer containing a CPU core, Flash/ROM program memory, SRAM data memory, timers, communication peripherals, and I/O. The PIC24FJ family uses a 16-bit modified Harvard RISC architecture with DSP extensions, making it a mid-range upgrade over 8-bit PIC16/PIC18 parts while staying below the cost of 32-bit ARM Cortex-M0 MCUs. It sits in the hierarchy: PIC24FJ -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor IC.
Key features of the PIC24FJ64GA110T-I/PT include 16 channels of 10-bit ADC (500 ksps), two UART, two SPI, two I2C peripherals, five 16-bit timers, an RTCC, and a Parallel Master Port (PMP) for external memory or graphics interfaces. The integrated nanoWatt technology provides multiple power-saving modes (Idle, Sleep, Deep Sleep) with on-the-fly clock switching, ideal for battery-powered designs. The 100-TQFP package offers generous pin count for complex human-machine interface (HMI) and sensor-fusion designs.
The 16-bit core with single-cycle multiply and hardware divide delivers deterministic interrupt response and DSP-class MAC operations, simplifying motor-control and digital-filter code versus 8-bit alternatives. The peripheral pin-select (PPS) feature allows flexible remapping of digital peripherals to any I/O, simplifying PCB layout in dense designs. On-chip CTMU enables touch sensing and capacitive proximity measurement.
Typical applications include industrial control panels, medical monitoring devices, USB embedded hosts (with external PHY), graphical user interfaces via PMP, motor control (BLDC, stepper), and consumer white goods. The wide memory and peripheral mix also suits building automation, HVAC controllers, and smart-meter designs.
When designing with this part, reserve adequate ground and VDD decoupling (100 nF + 10 µF bulk per pair) within 5 mm of each power pin. Use ICSP programming headers on every prototype for field updates; the PGECx/PGEDx pairs are mapped to fixed pin pairs.

Aplicações típicas
PIC24FJ64GA110T-I/PT é adequado para 7 aplicaçãos: Industrial Control Panels, USB Embedded Host / Device, Graphical User Interface (PMP), Motor Control (BLDC / Stepper), Smart Energy Metering, Medical Monitoring Devices, Consumer White Goods (Washing Machine / Dishwasher).
Industrial Control Panels
The PIC24FJ64GA110T-I/PT is well-suited to industrial control panels thanks to its 84 GPIO, 100-TQFP pin budget, and 16-channel 10-bit ADC that handles multiple sensor inputs (temperature, pressure, level) simultaneously. Its 32 MHz / 16 MIPS core executes real-time control loops within deterministic interrupt latency, critical for PID-driven motor and process loops. nanoWatt power modes reduce idle energy use in panel-mounted HMIs, while the industrial -40C to +85C rating supports factory-floor deployment. Recommended companions: PIC24FJ128GA110T-I/PT for expanded firmware and LAN8720A Ethernet PHY for networked panels.
Recomendado
USB Embedded Host / Device
The PIC24FJ64GA110T-I/PT implements USB 2.0 full-speed device and limited host via the integrated USB module (when paired with external transceiver support in the GA110 family), eliminating an external USB controller IC. With 64 KB Flash and 8 KB RAM, it can host mass-storage, HID, or CDC class drivers in small embedded applications. PPS lets designers route USB D+/D- to convenient board locations. Recommended companions: PIC24FJ256GB110T-I/PT for full USB-OTG workloads, and USBLC6-2SC6 for ESD protection on D+/D- lines.
Recomendado
Graphical User Interface (PMP)
The PIC24FJ64GA110T-I/PT's Parallel Master Port (PMP) drives external graphics controllers, OLED modules, or memory-mapped LCDs at up to 25 MHz bus speeds, suitable for monochrome displays and small color TFTs with external controller. The 84 GPIO budget accommodates both PMP data/control and touch-panel sensing via CTMU, enabling resistive and capacitive touch screens. 16 MIPS handles menu rendering and input debounce in real time. Recommended companions: SSD1963 graphics controller for TFT up to 800x480 and MCP1700 LDO for the display backlight supply.
Recomendado
Motor Control (BLDC / Stepper)
The PIC24FJ64GA110T-I/PT's 16-bit DSP-enhanced core performs Park/Clark transforms and PI current loops for sensorless BLDC control with deterministic interrupt latency under 50 ns. Five 16-bit timers with PWM outputs generate complementary switching signals for three-phase bridges. The 10-bit ADC at 500 ksps samples phase currents fast enough for 20 kHz PWM cycles. Recommended companions: MCPWM-compatible gate drivers such as MCP8021 and ACS712 current sensors on each phase leg.
Recomendado
Smart Energy Metering
The PIC24FJ64GA110T-I/PT combines RTCC for time-of-use billing, 10-bit ADC for power-quality measurements (voltage, current, power factor), and 64 KB Flash for metering firmware stacks in compact single-phase and three-phase smart meters. nanoWatt Deep Sleep with RTCC running preserves battery-backed RTC operation during line-power outages. Recommended companions: ADE7953 poly-phase energy metering IC for metrology and ESP-12 Wi-Fi module for AMI backhaul.
Recomendado
Medical Monitoring Devices
The PIC24FJ64GA110T-I/PT suits portable patient monitors (pulse oximetry, temperature, ECG front-end) where 16 MIPS provides enough headroom for FIR filtering of biosignals while 8 KB RAM buffers sample data. The CTMU module supports capacitive touch controls on the device enclosure. nanoWatt Sleep extends battery life for handheld designs; the industrial temperature grade supports hospital and home-care environments. Recommended companions: ADS1292R ECG AFE and TMP36 analog temperature sensor.
Recomendado
Consumer White Goods (Washing Machine / Dishwasher)
The PIC24FJ64GA110T-I/PT provides the I/O count and computational throughput needed for front-panel keypads, motor control, water-level sensing, and user-interface displays in washing machines and dishwashers. The PMP peripheral drives segment LCDs and small graphical OLEDs, while CTMU replaces mechanical keypads with capacitive touch panels. nanoWatt modes keep standby power below 1 W to meet global energy regulations. Recommended companions: MCP8021 motor gate driver and MCP1700 LDO.

Principais diferenciais
- Pin-compatible Flash upgrade options in same 100-TQFP package (vs PIC24FJ64GA110T-I/PF)
- nanoWatt technology with integrated RTCC (vs PIC24FJ64GA110-I/PT)
- DSP-extended 16-bit core at 32 MHz (vs PIC24FJ256GB110T-I/PT)
Notas de projeto
Estimated: at 32 MHz CPU and 84 GPIO switching, the PIC24FJ64GA110T-I/PT consumes approximately 25-30 mA from a 3.3 V supply. Place a 100 nF ceramic decoupling capacitor within 5 mm of each VDD pin and a single 10 µF bulk capacitor near the MCU. Connect all VSS pins to a low-impedance ground plane to avoid ground bounce on high-speed GPIO transitions. For battery-powered designs, enable nanoWatt Sleep or Deep Sleep mode between tasks to drop consumption below 100 µA.
Route the 100-TQFP land pattern on the standard 0.5 mm pitch with 4-layer stack-up (signal / ground / power / signal). Place the crystal oscillator traces within 10 mm of the OSC1/OSC2 pins, guarded by a ground ring to minimize EMI coupling. Use a dedicated ICSP programming header footprint on the prototype with PGEC1/PGED1 brought to a 0.1 inch header for field firmware updates; alternatively assign these pins to peripheral functions only after considering production programming flow.
Configuration bits must be programmed in the IDE before the MCU executes user code; an unconfigured part leaves all pins as analog inputs and the oscillator disabled. The Peripheral Pin Select (PPS) registers must be unlocked via IOLOCK before reassigning remappable peripherals, and re-locked afterward to prevent runaway writes. Do not exceed 10 mA per I/O pin or 200 mA total across all I/O; load larger signals through driver transistors.
