PIC24FJ64GA306T-I/MR 개요
A 16-bit microcontroller is a single-chip computer that uses an internal data path 16 bits wide, enabling more efficient arithmetic on larger integers and richer peripheral addressing than 8-bit cores while retaining low power consumption. PIC24F microcontrollers sit within the broader hierarchy of microcontroller -> embedded controller -> semiconductor; the FJ sub-family adds nanoWatt XLP technology and integrated LCD driver support, positioning this device for low-power human-machine interface designs.
Key features include nanoWatt XLP technology with a Low Voltage Sleep current of approximately 340 nA that retains RAM and core state, a real-time clock and calendar (RTCC) module, a 10-bit ADC capable of up to 500 ksps, multiple UART/SPI/I2C peripherals, and a dedicated LCD segment driver interface. The CTMU charge-time measurement unit enables touch sensing and capacitance measurement, while a 16-bit parallel master port and EPMP support external bus expansion for graphics or memory.
Architecturally, the PIC24FJ64GA306T-I/MR pairs a wide 16-bit ALU with a 24-bit instruction word to balance code density and execution speed. The integrated voltage regulator supports operation down to 2.0V, and the peripheral pin select (PPS) feature allows digital peripheral I/O to be remapped to most general-purpose pins, simplifying PCB routing. Hardware crypto and unique MAC address support are absent on this part; cryptographic options are addressed by separate PIC24Fxx and dsPIC33 families.
Typical applications include battery-powered IoT sensor nodes, portable medical monitors, smart metering with LCD readouts, industrial HMI panels, USB peripherals using an external transceiver, and low-power remote controls. The wide operating temperature range of -40C to +85C makes the device suitable for industrial and outdoor installations.
When designing with this device, ensure that Vcap decoupling is provided per datasheet recommendations and that unused I/O pins are configured as outputs to minimize transient current. PPS configuration should be locked early in initialization to prevent bus contention during bootstrap.

일반적인 애플리케이션
PIC24FJ64GA306T-I/MR 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Node, Portable Medical Monitor, Smart Meter with LCD Readout, Industrial HMI Control Panel, USB HID Peripheral Device, Low-Power Remote Control.
Battery-Powered IoT Sensor Node
The PIC24FJ64GA306T-I/MR fits IoT sensor node designs because its nanoWatt XLP technology holds RAM and core state at approximately 340 nA in Low Voltage Sleep mode, allowing multi-year coin-cell operation. With 16 MIPS throughput at 32 MHz it can wake, sample, and transmit within tight duty cycles. Its 2.0V-3.6V range matches two AA cells directly, removing the need for boost converters. The CTMU peripheral enables accurate temperature and capacitive touch readings without extra analog ICs, and 85 I/O plus PPS routing accommodate many sensor buses in a single MCU.

Portable Medical Monitor
The PIC24FJ64GA306T-I/MR supports portable medical monitors by combining deterministic 16 MIPS throughput for real-time signal processing with a 10-bit ADC for biopotential measurements such as pulse oximetry or ECG front ends. The 64 KB Flash accommodates compressed waveform buffers and BLE stack stubs, and the wide 2.0V-3.6V range simplifies lithium-battery management. Hardware CTMU and op-amp peripherals reduce external analog parts count, critical for small-form-factor wearable designs, and the industrial -40C to +85C rating covers home and clinical environments.
추천
Smart Meter with LCD Readout
The PIC24FJ64GA306T-I/MR is ideal for smart electricity and water meters because its integrated LCD segment driver directly controls character and bar displays without an external driver IC. Its 16 MIPS core performs metrology math, while the RTCC module maintains accurate time-of-use billing and tariff scheduling. The 85 I/O count accept multi-channel ADC inputs for current/voltage sensing, and nanoWatt XLP modes keep idle power below the regulatory standby limits of metering standards. Industrial temperature range ensures outdoor cabinet deployments operate reliably year-round.
추천
Industrial HMI Control Panel
The PIC24FJ64GA306T-I/MR drives industrial HMI panels thanks to its 16-bit parallel master port (EPMP) for fast LCD or external memory expansion, 85 I/O for keypads and discrete status LEDs, and 32 MHz performance for menu rendering. The 2.0V-3.6V range supports 3.3V-native backplane designs, and the integrated LCD controller eliminates a separate graphics IC. With PPS routing, UART, SPI, and I2C peripherals share buses flexibly with industrial transceivers such as RS-485 and CAN interfaces.
추천
USB HID Peripheral Device
The PIC24FJ64GA306T-I/MR pairs with an external USB transceiver such as the MCP2210 or MCP2200 to implement USB HID peripherals including keyboards, mice, and custom input devices. Its 32 MHz performance handles USB polling and HID report generation without offloading to a host PC. The 64 KB Flash accommodates HID descriptors and firmware update routines, while 8 KB RAM supports HID report buffers and protocol stacks. PPS flexibility lets designers route USB interrupt lines to convenient pins without rewiring.
추천
Low-Power Remote Control
The PIC24FJ64GA306T-I/MR suits battery-powered remote controls thanks to its 340 nA Sleep current and rapid wake-up from nanoWatt XLP modes. The 64 KB Flash stores keypad matrices and RF protocol stacks, while the CTMU supports capacitive touch keys without mechanical switches. The 16 MIPS core runs IR or sub-GHz RF encoding schemes such as NEC or LoRa, and the industrial temperature range ensures operation in automotive cabins and outdoor environments. PPS routing eases PCB antenna placement around the 64-pin VQFN footprint.

- 340 nA Low Voltage Sleep current with full RAM retention (vs PIC24FJ128GA306T-I/MR)

설계 노트
Always place a low-ESR ceramic capacitor (typically 10 uF) on the Vcap pin of the PIC24FJ64GA306T-I/MR. The internal 1.8V core regulator requires this bulk capacitor for stability, and missing or undersized capacitors cause erratic resets or core undervoltage faults. Add a 100 nF decoupling capacitor close to each VDD pin pair to suppress switching transients.
Solder the exposed thermal pad (EP) of the 64-pin VQFN (9x9 mm) to a continuous ground copper pour. A floating or partially soldered pad increases junction temperature and degrades ADC accuracy because the pad serves as the primary thermal and electrical ground return. Follow Microchip's recommended land pattern with multiple thermal vias under the pad for best thermal performance.
Configure all unused I/O pins as digital outputs driving low (or as inputs with the internal weak pull-up enabled) before entering Sleep modes. Floating inputs draw transient current and can wake the device unexpectedly. Lock Peripheral Pin Select (PPS) registers early in initialization by clearing IOLOCK after configuring all peripherals to prevent accidental bus contention.
Estimated: at 32 MHz CPU with multiple peripherals active simultaneously, route high-speed signals (SPI clocks above 10 MHz, parallel master port) on inner PCB layers with continuous ground reference. Keep traces shorter than 50 mm and avoid via stubs to maintain signal integrity. The 10-bit ADC accuracy of the PIC24FJ64GA306T-I/MR is sensitive to digital switching noise, so isolate analog traces and decouple AVdd independently from Vdd where the package exposes a separate analog supply pin.
