PIC24FJ64GA110T-I/PF Visão geral
A 16-bit microcontroller (MCU) is a programmable computing device that uses a 16-bit data path and instruction word to balance code density, deterministic behaviour, and peripheral integration for embedded systems. PIC24F devices sit in Microchip's 16-bit portfolio between 8-bit PIC16/PIC18 parts and 32-bit PIC32 parts, and they belong to the broader microcontroller > microcontroller IC > semiconductor taxonomy. The 16-bit architecture delivers higher MIPS per MHz than 8-bit cores while remaining easier to learn and tool than 32-bit ARM Cortex-M parts, making PIC24F a common choice for cost-sensitive, low-power, mixed-signal designs.
Key features include 32 MHz operation delivering up to 16 MIPS, 64 KB Flash / 16 KB RAM, integrated 16-channel 10-bit ADC, up to 85 GPIO, and multiple serial interfaces (3x I2C, 3x SPI, 4x UART) plus 23 independent timers per the PIC24FJ256GA110 family datasheet. The nanoWatt technology label indicates deep-sleep currents below 100 nA for battery-backed applications. Compared with PIC24FJ128 variants this part uses half the Flash and so is positioned for budget-constrained designs that do not need 128 KB.
Architecturally, the PIC24FJ64GA110T-I/PF uses a modified Harvard core with separate program and data buses, a hardware multiply/divide unit, and a peripheral engine capable of running PWM, ADC, and communication blocks independently of the CPU. The 100-TQFP package exposes most pins as GPIO and as alternate-function peripheral mappings, enabling large mixed-signal designs with both analog sensing and digital I/O. Industrial-grade silicon and the 16 MIPS throughput make it suitable for real-time control loops such as BLDC motor commutation, sensor fusion front-ends, and human-interface subsystems.
Typical applications include industrial sensor hubs, BLDC and stepper motor control, USB-aware human-interface panels, and low-power remote sensor nodes. Designers also use this family for graphical displays, multi-protocol bridges, and medical/consumer devices that need more than an 8-bit MCU but do not justify a 32-bit part. The tape-and-reel -T suffix indicates factory packaging for SMT assembly lines, and the -I grade supports commercial-to-industrial enclosures.

Aplicações típicas
PIC24FJ64GA110T-I/PF é adequado para 6 aplicaçãos: Industrial Sensor Hubs and Data Acquisition, BLDC and Stepper Motor Control, Human-Machine Interface (HMI) Panels, Low-Power Remote Sensor Nodes, USB-Aware Embedded Devices, Medical and Consumer Monitoring Devices.
Industrial Sensor Hubs and Data Acquisition
The PIC24FJ64GA110T-I/PF is well suited to industrial sensor hubs because it integrates a 16-channel 10-bit ADC capable of scanning thermocouple, RTD, 4-20 mA, and bridge sensor front-ends at the 32 MHz / 16 MIPS throughput. At -40C to +85C industrial operation and with on-chip Brown-out Reset plus LVD, the device maintains measurement integrity across factory floor transients per the Microchip PIC24FJ256GA110 family datasheet. The four UART and three SPI/I2C peripherals let one MCU aggregate multiple fieldbus segments and forward to a higher-level PLC. With 16 KB RAM the device can buffer sample bursts before uplink, and the 64 KB Flash accommodates calibration tables and Modbus/RTU protocol stacks without external memory.
Recomendado
BLDC and Stepper Motor Control
The PIC24FJ64GA110T-I/PF delivers real-time motor commutation thanks to its 16 MIPS throughput, dedicated PWM output-compare channels, and a 16-channel 10-bit ADC for back-EMF and current shunt sampling. The 100-TQFP variant exposes the full PWM and QEI peripheral set per the PIC24FJ256GA110 family datasheet, allowing field-oriented control of three-phase BLDC or two-phase stepper motors. The 4x UART enables encoder or RS-485 feedback, and the nanoWatt sleep mode below 100 nA keeps standby power low for battery-driven actuator boards. Drop-in scalability to PIC24FJ128GA110T-I/PF allows the same PCB to ship in low-cost and high-feature variants.
Recomendado
Human-Machine Interface (HMI) Panels
The PIC24FJ64GA110T-I/PF serves cost-sensitive HMI panels by integrating up to 85 GPIO to drive keypads, LED matrices, character LCDs, and segmented displays directly from a single MCU. Its 3x SPI and 3x I2C peripherals interface to capacitive touch controllers, RTCs, and EEPROM without external logic, and the four UARTs connect to host PLCs. Per the PIC24FJ256GA110 family datasheet, the 32 MHz / 16 MIPS core can debounce key matrices, render menus, and run Modbus in real time while the nanoWatt idle mode drops below 100 nA between user interactions. The 100-TQFP industrial grade ensures operation in sealed IP65 enclosures.
Recomendado
Low-Power Remote Sensor Nodes
The PIC24FJ64GA110T-I/PF is ideal for battery-powered remote sensor nodes because its nanoWatt technology drops standby current below 100 nA per the Microchip PIC24FJ256GA110 family datasheet, while the 16 MIPS active throughput lets it wake, sample, transmit, and return to sleep quickly to maximise battery life. The 16-channel 10-bit ADC reads temperature, humidity, and battery voltage, and the on-chip UART/SPI/I2C blocks connect to wireless transceivers without glue logic. With 16 KB RAM the part can buffer queued transmissions between LoRa or BLE windows. The 100-TQFP industrial temperature range covers outdoor enclosures from -40C to +85C.
Recomendado
USB-Aware Embedded Devices
The PIC24FJ64GA110T-I/PF integrates USB On-The-Go (OTG) peripheral support per the PIC24FJ256GA110 family datasheet, allowing it to act as USB device or limited host in 100-TQFP designs without an external PHY. Its 32 MHz core can drive the USB 2.0 full-speed stack, the 16 KB RAM buffers HID/CDC frames, and the 64 KB Flash holds CDC, HID, or vendor-class stacks. Industrial-grade silicon plus the -40C to +85C temperature range supports USB-equipped test instruments and medical peripherals. The drop-in PIC24FJ128GA110T-I/PF accommodates richer composite-USB stacks in the same PCB.
Recomendado
Medical and Consumer Monitoring Devices
The PIC24FJ64GA110T-I/PF fits medical and consumer monitoring devices where 16 MIPS processing and 16-channel 10-bit ADC deliver accurate biosignal conditioning at low power. Per the PIC24FJ256GA110 family datasheet, the device integrates LVD, Brown-out Reset, and a Watchdog Timer for IEC-style functional safety patterns required in patient-adjacent designs. The 64 KB Flash fits algorithm code for pulse oximetry, glucometry, or fitness monitors, while the four UARTs link to BLE radios and the 100-TQFP industrial-grade package survives -40C to +85C storage. Drop-in to PIC24FJ128GA110T-I/PF allows the same PCB to ship in entry and premium SKUs.

Notas de projeto
The PIC24FJ64GA110T-I/PF requires a stable 2.5 V to 3.6 V supply with decoupling placed within 5 mm of every VDD/VSS pair. The 100-TQFP package has multiple VDD/VSS pins that must each have a 100 nF ceramic plus a 4.7 uF bulk capacitor per the Microchip PIC24FJ256GA110 family datasheet. The on-chip LVD and Brown-out Reset must be enabled in firmware to protect Flash integrity below 2.3 V; leaving these disabled risks corrupted Flash during supply dips in motor-control or industrial environments.
The 100-TQFP 14x14 mm footprint requires 0.5 mm pitch gull-wing pads; allocate at least 0.2 mm between pad and via to maintain solder mask dams. Place the ICSP programming header (RB6/ICSPCLK and RB7/ICSPDAT plus MCLR/VPP) on the board edge so a Microchip PICkit can attach without removing the chip. The 32 MHz primary oscillator traces should be kept short and guarded with a ground ring per the family datasheet section on high-frequency PCB layout.
Avoid driving the MCLR pin low unintentionally through stray leakage - the pin has an internal pull-up but external noise below 0.2 VDD can reset the part. When using nanoWatt sleep modes, disable peripherals in the correct order and clear the corresponding interrupt flags before WFI to prevent immediate wake-up. For USB OTG operation, the internal 48 MHz USB clock must be enabled before USB module configuration, or the USB module will fail to enumerate - check section on oscillator configuration in the family datasheet.
The 16-channel 10-bit ADC is sensitive to digital switching noise - separate analog AVDD from digital VDD with a ferrite bead and provide a quiet analog ground plane under analog-capable pins. When sampling high-impedance sensors, set adequate ADC acquisition time (typically 20 Tad) to avoid channel-to-channel crosstalk. For PWM-driven motor outputs, route the high-current PWM traces away from the analog inputs to minimise capacitive coupling into ADC samples.
