PIC24FJ64GL302-I/SS 概要
What is an XLP microcontroller? An XLP (eXtreme Low Power) microcontroller is a class of MCU designed for battery-powered applications where sleep current must be in the microampere or nanoampere range while retaining RAM and configuration registers. Within Microchip's PIC24F family hierarchy (PIC24F -> PIC24FJ -> 'GL' LCD sub-family -> XLP variant), the 'GL' devices add a segmented LCD driver and a charge pump to the XLP architecture, enabling direct connection of LCD glass without external bias generation. This positions the PIC24FJ64GL302 in the broader category of power management ICs -> mixed-signal microcontrollers -> low-power MCUs with integrated display drivers.
Key features of the PIC24FJ64GL302 include sub-uA sleep currents with full RAM retention, autonomous LCD animation that runs without CPU intervention (alternating dual display, blinking, blanking), an on-chip LCD charge pump that maintains contrast down to battery low-voltage conditions, and a 16-channel 12-bit ADC. The 'GL' family CIP block set allows display updates, ADC sampling, and timer operations to run independently of the CPU, minimizing wake events and extending battery life.
In typical applications, the PIC24FJ64GL302 targets battery-powered human-machine interface products: thermostat controls, portable medical monitors, fitness trackers, electronic shelf labels (ESL), utility meters with LCD readouts, and consumer appliances with segmented displays. Designers choose this part when the system needs an LCD glass display, weeks-to-years of battery life, and sufficient MIPS for sensor processing without a dedicated display controller IC.
When designing with this MCU, plan the LCD bias and segment multiplexing topology against the chosen glass, route the charge-pump capacitors close to the device, and leverage MPLAB Code Configurator (MCC) to set up CIP chains. For multi-rail systems, the deep-sleep wake sources (RTC, external interrupt, watchdog) should be mapped to the application wake event to minimize average current.

主な用途
PIC24FJ64GL302-I/SS の用途: 7 件s: Battery-Powered Thermostat, Portable Medical Monitor, Electronic Shelf Label (ESL), Utility Meter with LCD Readout, Industrial Sensor Transmitter with LCD, Consumer Appliance with Segmented Display, Fitness Tracker / Wearable.
Battery-Powered Thermostat
The PIC24FJ64GL302-I/SS is ideal for battery-powered thermostat designs because its integrated segmented LCD controller can drive a 4-7 digit temperature/status glass directly, while the on-chip charge pump maintains contrast as the battery drains. Sub-uA deep-sleep current with full RAM retention enables multi-year battery life on 2xAA cells. Core-independent peripherals (RTCC for timekeeping, CLC for thermostat hysteresis logic) keep wake events to a minimum. 64KB flash supports a modest UI library including custom segment fonts, weekday icons, and setpoint menus.
おすすめ
Portable Medical Monitor
Portable medical monitors such as blood pressure cuffs, pulse oximeters, and glucose meters benefit from the PIC24FJ64GL302's on-chip 12-bit ADC, segmented LCD driver, and XLP deep-sleep current. The autonomous LCD animation CIPs run display updates without CPU intervention while the core samples the sensor and computes readings, lowering average power. The 28-SSOP package enables compact hand-held designs, and 64KB flash supports FDA-relevant firmware with calibration tables and trending logs.
おすすめ
Electronic Shelf Label (ESL)
ESL designs require segmented LCD, RF or BLE wake-up, and years of battery life - the PIC24FJ64GL302-I/SS matches this profile. Sub-uA sleep current with full RAM retention preserves display content while the radio is off; the LCD controller and autonomous animation handle price flashing and blinking without CPU load. The 64KB flash fits ESL protocol stacks plus price/font tables, and the SSOP-28 package supports both 1.5V and 3V battery topologies via the 2.0-3.6V VDD range and on-chip charge pump.
おすすめ
Utility Meter with LCD Readout
Smart water, gas, and electric meters integrate a segmented LCD for consumption, tariff, and status display. The PIC24FJ64GL302's 16 MIPS core supports meter protocol logic, the integrated LCD controller drives multi-digit glass with the on-chip charge pump ensuring contrast across battery voltage decay, and the RTCC + CLC CIPs implement tamper detection and timekeeping without CPU wake. Low sleep current extends battery life to the 10+ year target typical of metering.
おすすめ
Industrial Sensor Transmitter with LCD
Industrial 4-20mA loop-powered or battery-backed sensor transmitters with local LCD readout benefit from the PIC24FJ64GL302's 12-bit ADC, segmented LCD controller, and CIP chain capability. The autonomous ADC-to-LCD update path removes CPU intervention from routine display updates, enabling lower sleep current. Industrial temperature range and SSOP-28 footprint simplify integration into compact IP65 enclosures for process measurement.
おすすめ
Consumer Appliance with Segmented Display
Consumer appliances (kitchen scales, coffee makers, microwaves, washing machines) with segmented LCD readouts pair well with the PIC24FJ64GL302. The XLP deep-sleep mode cuts idle current to sub-uA levels for battery-backed displays; the LCD controller drives 7-segment digits plus icon segments; CIPs (CLC, MCCP) implement motor control, button debounce, and timer logic without CPU load. 64KB flash supports menu/preset firmware plus bootloader for field updates.
おすすめ
Fitness Tracker / Wearable
Wearable devices requiring compact segmented displays for step count, time, and notifications can use the PIC24FJ64GL302. The sub-uA sleep current with RAM retention preserves display content while sensors are off, and the integrated LCD controller and charge pump drive small-format glass directly without external bias ICs. The 28-SSOP package supports compact wearable form factors, while 64KB flash covers activity classification firmware and BLE data reduction logic.

設計ノート
Estimated: at VDD=3.3V and CPU active at 32 MHz, the PIC24FJ64GL302 consumes approximately 6-8 mA in Run mode; in deep sleep with RAM retention, current drops to sub-uA levels. For battery-powered designs, choose Doze mode with peripherals on RTCC wake to balance computation throughput and average current. Decouple VDD with 100nF + 1uF ceramic close to the VDD/VSS pairs, and route the LCD charge-pump capacitors (CFLY, CBYPASS) within 3mm of the device.
Estimated: the 28-SSOP package requires PCB land patterns per IPC-7351 with 0.65 mm pitch. Route the LCD segment signals to the glass connector with 0.2 mm minimum trace/spacing. All VSS pins (pin 6 and pin 28) MUST be connected to a low-impedance ground plane, and all VDD pins must be decoupled. The ICSP pairs PGEC2/PGED2 (pins 9/10) should be brought to test points or a 2x5 header for programming. The package thermal resistance theta_JA for SSOP-28 is approximately 71 C/W, so the device does not require a thermal pad for normal MCU operation.
Common pitfalls with the PIC24FJ64GL302 include: (1) forgetting to connect ALL VDD and VSS pins - omitting even one VDD/VSS pair causes programming failure per the Microchip datasheet; (2) using PGEC2 with PGED3 or other mismatched ICSP pairs - ICSP requires matched pair; (3) configuring the LCD charge pump at voltages above the selected VDD range which can over-stress the pump; (4) enabling segmented LCD outputs without enabling the charge pump, leading to ghost segments at low VDD. Use the MPLAB Code Configurator (MCC) 'LCD Driver' component to configure display registers correctly and validate timing in simulation before fabrication.
Estimated: place the 32.768 kHz crystal (if used for RTCC) close to the SOSCI/SOSCO pins with short traces and a guard ring to reduce clock jitter. Route the high-speed I/O (UART, SPI signals) away from the LCD segment traces to minimize coupling. For the segmented LCD, route commons and segments orthogonally if the layout allows, and place bias resistors on the LCD glass connector as recommended by the glass manufacturer. Keep digital switching signals (PWM, fast GPIOs) physically separated from the analog sensor inputs (RA0-RA3) by at least one ground guard trace.
