What is a nanoWatt XLP microcontroller? It is a low-power MCU class designed for battery-powered and energy-harvesting applications. The XLP architecture extends standard sleep modes with deep retention states where RAM and core registers are preserved at nanoampere-level currents, allowing wake-on-interrupt designs that can run for years on a single coin cell. The PIC24FJ family occupies the mid-range 16-bit tier of Microchip's portfolio, positioned above 8-bit PIC18 and below 32-bit PIC32MK/PIC32MX devices, with the GA310 subgroup adding the integrated segment LCD controller and 100-pin scalability required for human-machine interface (HMI) panels.
Key features include a typical Low Voltage Sleep current of 340 nA (per the manufacturer datasheet) with full RAM retention, Vbat battery backup input for RTC, integrated segmented LCD controller supporting up to 480 segments, 10-bit ADC with 1 MSPS, mTouch capacitive touch support, and 16-bit CRC hardware. The device supports 2.0V to 3.6V single-supply voltage, and multiple low-power modes including Doze, Idle, Sleep, and Retention with selective peripheral clock gating.
The architecture pairs a 16-bit modified Harvard CPU with a hardware Multiply/Divide unit, achieving 16 MIPS at 32 MHz. This balances throughput for human-interface control loops with deterministic interrupt latency, which is critical for motor-control and industrial-sensor applications. Code is executed from Flash via a 24-bit instruction path; Flash self-read during execution is supported, removing the need for an external boot device.
Typical applications include battery-powered IoT sensor nodes with segment-LCD readouts, industrial process meters with HMI displays, handheld medical monitors, e-paper/e-ink controller boards, and remote control panels. Designers also deploy the part in low-power wireless sensor hubs and HVAC thermostat front-end boards where the integrated LCD segment driver eliminates an external driver ASIC.
When designing with this part, confirm that the PCB pad pattern matches the 100-pin TQFP 14x14 mm land geometry and plan for a programming/debug connector (MCLR, PGC, PGD). Choose 1.8V-3.6V rated external components since the part cannot tolerate 5V I/O.

Aplikasi Umum
PIC24FJ64GA310-I/PF cocok untuk 7 aplikasis: Battery-Powered IoT Sensor Hub with LCD Readout, Industrial Process Meter with HMI Display, Handheld Medical Monitor / Diagnostic Device, HVAC Thermostat Front-End Controller, E-Paper / E-Ink Display Controller Board, Remote Control Panel / Appliance HMI, Low-Power Wireless Sensor Hub (Sub-GHz/Zigbee).
Battery-Powered IoT Sensor Hub with LCD Readout
The PIC24FJ64GA310-I/PF fits battery-powered IoT sensor hubs with LCD readouts because its nanoWatt XLP architecture achieves 340 nA typical sleep current with full 8 KB RAM retention per the manufacturer datasheet, and it integrates a segmented LCD controller (up to 480 segments) that drives a numeric or glass LCD without an external driver ASIC. The 32 MHz / 16 MIPS 16-bit core handles periodic sensor acquisition, averaging, and protocol framing (I2C sensor polling, UART-modem forwarding) on a duty-cycled schedule, then returns to retention sleep between samples, enabling multi-year coin-cell operation. The 100-pin TQFP gives designers 85 GPIO pins to multiplex the LCD, sensors, and a wireless module without bus contention.

Industrial Process Meter with HMI Display
Industrial process meters with HMI displays are a primary application for the PIC24FJ64GA310-I/PF because the on-chip segment LCD controller drives multi-digit industrial meter readouts (pressure, flow, level) directly, eliminating the need for a separate LCD driver chip and saving BOM cost. The 10-bit 1 MSPS ADC samples 4-20 mA loop current or 0-10 V transducer signals with hardware averaging, while the RTCC with Vbat backup preserves time-stamped logs across main power loss. The 100-pin TQFP (PF) package supports a wide pinout that exposes enough I/O for relay outputs, button inputs, and an RS-485 UART for Modbus RTU without external mux logic.

Handheld Medical Monitor / Diagnostic Device
Handheld medical monitors and diagnostic devices use the PIC24FJ64GA310-I/PF because its XLP sleep modes keep quiescent draw in the nanoamp range while preserving the 8 KB RAM that holds patient history between operator actions, and its 16 MIPS throughput is sufficient to run filtering algorithms on bio-sensor waveforms. The integrated 10-bit ADC paired with an external low-noise op-amp captures SpO2, ECG, or temperature signals; the LCD controller drives a monochrome medical-grade LCD; and the Vbat pin keeps the real-time clock alive on a coin cell when the main battery is removed for replacement, preserving timestamp continuity for compliance auditing.

HVAC Thermostat Front-End Controller
HVAC thermostat front-end controllers deploy the PIC24FJ64GA310-I/PF because it natively drives a multi-segment LCD for temperature/setpoint/time display, runs PID-like control loops on its 16 MIPS core for relay-driven HVAC actuators, and supports capacitive mTouch sensing for glass-front keypads via the integrated CTMU peripheral. Sleep currents in the nanoamp range keep idle thermostats from draining the common-wire 24 VAC supply during standby; the Vbat backup preserves schedule memory through brownouts; and the 100-pin TQFP footprint leaves headroom for additional I/O such as humidity sensors, CO2 sensors, and a Wi-Fi module UART.

E-Paper / E-Ink Display Controller Board
E-paper and e-ink display controllers pair naturally with the PIC24FJ64GA310-I/PF because e-ink panels require sustained low duty-cycle operation with periodic refreshes, exactly the use case the XLP sleep mode optimizes for. The 16-bit core generates the EPD waveform timing tables and SPI commands for the display, then enters deep sleep between page updates, drawing microampere-level current while RAM holds the rendered bitmap. The integrated LCD segment controller is repurposed to drive a low-power status LED or auxiliary status panel alongside the main e-ink panel.

Remote Control Panel / Appliance HMI
Remote control panels and appliance HMI boards use the PIC24FJ64GA310-I/PF because the integrated segmented LCD controller drives button labels, status icons, and multi-character readouts without a separate driver, while mTouch-capable I/O implement touch buttons on glass-front panels. The 16-bit core decodes touch events, runs user-interface state machines, and drives TRIAC/relay outputs for the appliance load; the wide 100-pin TQFP exposes enough I/O for backlight PWM, buzzer, encoder inputs, and a UART debug port. Low-voltage sleep current keeps standby power below the Energy Star threshold for always-on appliances.

Low-Power Wireless Sensor Hub (Sub-GHz/Zigbee)
Low-power wireless sensor hubs and sub-GHz/Zigbee coordinators use the PIC24FJ64GA310-I/PF as the host MCU because it can stay in 340 nA retention sleep for long intervals while preserving the network table and route information in 8 KB RAM, then wake on RTCC or radio interrupt to forward packets. The 16 MIPS throughput handles packet encryption, sensor polling, and local control loops without external logic; the 100-pin TQFP exposes UART/SPI for the radio module plus parallel I/O for status LEDs; and the wide VDD range (2.0-3.6 V) lets the same board run from a 3.6V primary lithium or a 2.4V NiMH battery pack.

Catatan Desain
The PIC24FJ64GA310-I/PF VDD range is 2.0 V to 3.6 V (single supply). For designs drawing power from a coin cell or energy harvester, place a 10 uF bulk capacitor and a 0.1 uF decoupling cap adjacent to each VDD/VSS pair (the PF package has multiple VDD/VSS pairs to reduce supply inductance). Use the Vbat pin to retain the RTCC across VDD loss; connect Vbat to a separate coin cell or super-cap, never to the main rail. Estimated: at 32 MHz active current ~8 mA typical (per datasheet), so a 3.3 V 100 mA LDO upstream is more than adequate.
The 100-pin TQFP (PF) footprint is 14x14 mm body with 0.5 mm pitch. Use at least 4-layer PCB with a continuous ground plane beneath the part to provide thermal spreading and low-impedance return paths for the 32 MHz core. Place the 32.768 kHz secondary oscillator crystal (SOSCI/SOSCO pins) as close to the part as possible with guard traces, and keep high-speed digital traces away from the analog AVSS/AVDD pair. Programming header footprint should expose MCLR, PGD, PGC and VDD for ICSP.
Do not assume the /PF and /PT suffixes are interchangeable - although both are 100-pin TQFP, /PT in other family members may denote a different pinout (e.g. 64-pin TQFP). Always cross-check the datasheet pinout before PCB layout. Also note that 'I' suffix denotes the industrial -40C to +85C temperature grade; the 'E' grade is extended -40C to +125C and the blank grade is 0C to +70C. Do not connect 5V logic signals directly to any GPIO - the absolute maximum Vih on the I/O pins is VDD + 0.3 V and 5V will damage the part.
When using the integrated segmented LCD controller, route the LCD segment and common lines with matched lengths where practical and keep the LCD bias generation capacitors close to the LCDbias pins. For designs driving capacitive touch via the CTMU peripheral, place the touch electrodes on the opposite side of the PCB from any high-current switching traces and use a ground pour underneath the touch area. If SPI is run above 4 MHz, add a 33 ohm series resistor on SCK near the MCU to dampen ringing, especially when the trace length exceeds 25 mm.
Informasi Konformitas
RoHS compliant per Microchip product page. Not AEC-Q100 qualified - this part targets industrial/consumer HMI rather than automotive. Operating temperature grade 'I' is -40C to +85C industrial range.
