PIC24FJ64GL303-I/M5 概要
A 16-bit microcontroller (MCU) is a single-chip processor with an internal data path and ALU width of 16 bits, sitting in the broader category of microcontrollers -> embedded microprocessors -> microcomputer ICs -> semiconductor ICs. The PIC24F family is a low-power modified-Harvard 16-bit architecture from Microchip, designed to deliver higher deterministic performance than 8-bit parts while keeping power consumption low. The GL sub-series extends this with an LCD charge pump for battery-driven contrast management and CIPs that run autonomously without waking the CPU.
Key features of the PIC24FJ64GL303-I/M5 include sleep current in the order of a few hundred nanoamps with full RAM and LCD retention, integrated LCD charge pump, segmented LCD controller supporting up to 256 segments, 8 KB SRAM, 64 KB ECC Flash program memory, multiple serial interfaces (UART, SPI, I2C) and on-chip peripherals that qualify it as an XLP device. The CIP block runs animations, timers, communications and ADC scans while the core stays asleep, which is the single biggest contributor to its average energy budget in real designs.
Typical applications include battery-powered medical devices (glucose meters, portable diagnostics), e-metering and smart utility endpoints, wearables, IoT sensor nodes with on-device LCD readouts, and human-machine interface panels. The wide LCD segment budget (256) and the charge pump specifically target segment LCDs that must stay readable down to coin-cell voltages without an external boost converter.
When designing with this part, choose decoupling capacitor values that match the LCD bias network recommended in the datasheet and ensure that the VBAT / charge pump pins have the layout clearances indicated in the package drawing. Pin assignments for analog, segment and I/O functions overlap, so the pin multiplexer configuration must be locked before the PCB layout is committed.

主な用途
PIC24FJ64GL303-I/M5 の用途: 6 件s: Battery-Powered Medical Devices (Glucose / Portable Diagnostics), Smart Utility Meters (Water / Gas / Heat / e-Metering), Wearable Health and Fitness Trackers, Industrial Sensor Nodes with LCD Readout, IoT Edge Devices with On-Device LCD, Home Appliance HMI Panels.
Battery-Powered Medical Devices (Glucose / Portable Diagnostics)
The PIC24FJ64GL303-I/M5 fits battery-powered medical devices because its few-hundred-nA sleep current with full RAM and LCD retention allows years of operation from a single coin cell. The integrated segmented LCD controller (up to 256 segments) and on-chip charge pump drive numeric readouts without external boost components, while Core Independent Peripherals (CIPs) handle sensor scans autonomously. With 64 KB ECC Flash and 8 KB SRAM, the part runs the small UI loop and diagnostic state machine while the LCD charge pump keeps the contrast readable as VDD drops.
おすすめ
Smart Utility Meters (Water / Gas / Heat / e-Metering)
For smart utility meters, the PIC24FJ64GL303-I/M5 provides the segmented LCD display drive, the charge pump for low-voltage LCD contrast, and the XLP sleep current profile required for 10+ year battery life on sealed endpoints. The 16 MIPS PIC24F core processes metering pulses and CIPs run tamper detection and communications timers without intervention. ECC Flash improves long-term data retention in harsh utility environments, and the 36-pin UQFN package keeps the meter head compact.
おすすめ
Wearable Health and Fitness Trackers
The PIC24FJ64GL303-I/M5 is a strong fit for wearable health and fitness trackers where the design needs a visible LCD readout (step count, heart rate) but the battery must last weeks. The integrated LCD controller and charge pump remove the need for an external display bias IC, while the XLP sleep mode keeps average current below what 8-bit MCUs achieve. CIPs let the accelerometer and heart-rate sensor interrupt-gather data while the core sleeps, and the 36-pin UQFN 5x5 mm footprint suits small wearable PCBs.
おすすめ
Industrial Sensor Nodes with LCD Readout
For industrial sensor nodes that must show a numeric or segmented status display, the PIC24FJ64GL303-I/M5 integrates the segmented LCD, the contrast charge pump and the industrial -40C to +85C temperature grade in a single chip. CIPs handle UART/SPI/I2C comms and ADC scans autonomously, reducing wake events. The 64 KB ECC Flash stores sensor calibration tables, and the small 36-pin UQFN footprint fits inside compact sensor heads.
おすすめ
IoT Edge Devices with On-Device LCD
The PIC24FJ64GL303-I/M5 suits IoT edge devices that need to display sensor readings locally without a wireless connection. The integrated LCD controller and charge pump drive the display directly from the coin cell, while the XLP architecture lets the device idle at nanoamp-level current between measurements. With 8 KB RAM, the part can buffer samples, and CIPs run the sampling loop autonomously. The /M5 UQFN package keeps the design compact for space-constrained IoT nodes.
おすすめ
Home Appliance HMI Panels
For home appliance human-machine interface (HMI) panels such as ovens, washing machines and thermostats, the PIC24FJ64GL303-I/M5 drives the segmented LCD directly while handling keypad scanning and rotary encoder inputs through CIPs without CPU wake. The integrated charge pump maintains display contrast across the 1.8-3.6 V supply range as batteries age, and the industrial temperature grade ensures operation behind a warm appliance fascia. The 36-pin UQFN 5x5 mm footprint suits compact front-panel PCBs.

設計ノート
Estimated: at VDD = 3.0 V, CPU idle, LCD charge pump on and full 256-segment drive enabled, average current is dominated by the LCD charge pump and the segmented display refresh. Decouple VDD with a 100 nF ceramic close to the pin and place a bulk 4.7 uF near the package. The datasheet specifies decoupling placement and capacitor values; do not substitute polarized caps on the VLCD bias rail - use ceramics as recommended.
The 36-pin UQFN 5x5 mm package has an exposed thermal pad that must be soldered to the ground plane for both thermal dissipation and electrical reference. Route segment and common signals with short, parallel traces to the LCD glass and keep digital switching lines away from the analog segment traces. Observe the Microchip package drawing clearance under the EP - vias in pad are recommended to keep the thermal path low-impedance.
Do not enable CIPs that share pins with the segment LCD without first locking the PPS / pin multiplexer - overlapping functions cause silent drive loss on the LCD. Always configure the LCD bias network (resistor ladder vs charge pump) before firmware start-up, and verify that the VLCD pin capacitor matches the datasheet value to avoid contrast drift across temperature. Avoid operating the core above 32 MHz / 16 MIPS without confirming VDD is in the high-VDD range; refer to the electrical characteristics table for the safe VDD vs speed boundary.
When using I2C / SPI on the same ports as segment pins, ensure that the digital output slew rate and drive strength are configured to avoid LCD waveform distortion. The CIP-based comms peripherals can run without waking the core, but the segment pin drive must remain active during comms - test with a worst-case pattern of segment updates interleaved with I2C transactions to confirm there is no flicker or contrast shift on the display.
