PIC24FJ64GL302-E/ML Overview
A PIC24 16-bit microcontroller is a member of the PIC24F 'XLP' (eXtreme Low Power) family of mixed-signal microcontrollers based on the Microchip 16-bit modified Harvard CPU core. Within the broader hierarchy, PIC24FJ64GL302 belongs to the PIC24F subfamily -> PIC24 family -> PIC microcontrollers -> 16-bit microcontrollers -> microcontrollers (MCU) -> embedded controllers -> semiconductor ICs. The 'GL' family specifically targets ultra-low-power human-machine interface (HMI) designs with integrated LCD glass driving and core-independent animation, eliminating the need for external LCD controllers or constant CPU intervention.
Key features include nanoWatt XLP sleep current in the hundreds of nanoamps while retaining RAM and complete register context, a charge pump for contrast management in battery-powered LCD applications, and core-independent autonomous animation (alternating dual display, blinking, and blanking). The device supports 2.0 V to 3.6 V single-supply operation and integrates an internal 32 kHz low-power RC oscillator plus a 32 MHz fast RC oscillator with PLL. Communications include I2C, SPI, and UART peripherals suitable for sensor aggregation and host connectivity.
Technically, the PIC24FJ64GL302-E/ML combines a 16-bit modified Harvard CPU core with a hardware multiply/divide engine, dual oscillator domains, and an RTCC (Real-Time Clock and Calendar) capable of running from a 32.768 kHz crystal. The XLP CIPs (CLC, MCCP/SCCP, 16-bit timers, hardware CRC, DMA) allow the CPU to remain dormant while peripherals service events, lowering system power consumption by orders of magnitude compared to CPU-driven designs. The integrated segmented LCD driver with charge pump operates directly from a single Li-ion/LiFePO4 cell without external voltage rails.
Typical applications include battery-powered metering (water, gas, electricity) with LCD readouts, medical infusion pumps and glucose meters, portable industrial HMI panels with keypads, smart home thermostats and appliances, wearable fitness devices, e-bike displays, and any 2 V-3.6 V system requiring an integrated low-power LCD interface. Designers benefit from the 'GL' family CIPs that offload animation and timing tasks from the CPU, extending battery life in always-on applications.

Typical Applications
PIC24FJ64GL302-E/ML is suitable for 6 applications: Battery-Powered Water/Gas/Heat Metering, Medical Infusion Pumps and Glucose Meters, Portable Industrial HMI Panels, Smart Home Thermostats and Appliances, Wearable Fitness and Health Monitors, E-Bike Displays and Battery Management.
Battery-Powered Water/Gas/Heat Metering
The PIC24FJ64GL302-E/ML's nanoWatt XLP sleep current (hundreds of nanoamps with RAM retention) and integrated segmented LCD driver with charge pump make it a drop-in fit for battery-powered water, gas, and heat meters that must operate 10+ years on a primary cell. The device's 64 KB ECC Flash supports metering firmware, calibration tables, and wireless M-Bus or LoRaWAN protocol stacks. The integrated LCD charge pump generates contrast voltage from a single Li-SOCl2 cell without external boost hardware, reducing BOM cost. The E-grade -40 °C to +125 °C range handles outdoor enclosure thermal swings, and the 28-QFN (6x6) package fits within typical meter form factors.
Recommended
Medical Infusion Pumps and Glucose Meters
The PIC24FJ64GL302-E/ML's AEC-Q100 qualification and integrated LCD driver are well-suited for medical infusion pumps and glucose meters where clean, readable patient displays and long battery life are required. The 16 MIPS performance handles UI updates, sensor sampling, and dose calculation while the XLP sleep mode preserves battery during idle periods between infusions or readings. The 28-QFN (6x6) footprint supports miniaturized handheld enclosures. The on-chip RTCC with 32.768 kHz crystal domain tracks dose history timestamps across power cycles, supporting medical data-logging compliance requirements.
Recommended
Portable Industrial HMI Panels
The PIC24FJ64GL302-E/ML's core-independent peripherals (CIPs) including CLC, MCCP/SCCP, and hardware CRC offload keypad scanning, debouncing, and signal conditioning from the CPU, allowing the industrial HMI to remain responsive even during heavy display refresh. The 256-segment LCD support (8 commons x 32 segments) drives multi-line alphanumeric displays without external drivers, and the integrated charge pump maintains contrast on cold days. Industrial handhelds benefit from the E-grade temperature range, ECC Flash for field reliability, and 28-QFN (6x6) package enabling compact PCBAs with battery and ruggedized enclosures.
Recommended
Smart Home Thermostats and Appliances
The PIC24FJ64GL302-E/ML is well matched to smart thermostat and appliance HMI designs where a segmented LCD displays setpoint, ambient temperature, and operating mode. The XLP sleep current of hundreds of nanoamps with full RAM retention allows the thermostat to remain network-responsive on battery backup during AC line outages. The integrated RTCC tracks time-of-use schedules for HVAC setback, and the I2C/SPI/UART peripherals connect to temperature/humidity sensors, Wi-Fi modules, and HVAC actuator drivers. The E-grade temp envelope tolerates equipment-room thermal conditions in unconditioned spaces.
Recommended
Wearable Fitness and Health Monitors
Wearable fitness devices benefit from the PIC24FJ64GL302-E/ML's nanoWatt XLP technology, integrated LCD for step count and calorie display, and E-grade temp range for outdoor use. The 32 MHz CPU executes pedometer and heart-rate algorithms while the XLP sleep current keeps the device alive for weeks on a single coin cell. The 28-QFN (6x6) package enables ultra-thin wearable enclosures, and the integrated charge pump supports LCD contrast in low-battery conditions. Designers can add BLE through the UART/SPI interfaces without disturbing the core MCU footprint or firmware architecture.
Recommended
E-Bike Displays and Battery Management
E-bike HMI displays benefit from the PIC24FJ64GL302-E/ML's integrated 256-segment LCD, automotive-grade AEC-Q100 qualification, and 2.0 V-3.6 V supply that operates directly from a 2S-3S Li-ion pack. The XLP sleep current preserves battery during parking, and the RTCC tracks ride time and service intervals. The 16 MIPS performance handles torque-sensor sampling and CAN-Bus communication with the motor controller. The 28-QFN (6x6) package survives vibration with proper PCB staking, and the I2C/SPI peripherals connect to battery-management ICs and torque sensors on the e-bike drivetrain.

Key Differentiators
- Extended automotive-grade temperature range (vs PIC24FJ64GL302-I/ML)
- Double the Flash for richer applications (vs PIC24FJ128GL302T-I/ML)
- Integrated LCD charge pump eliminates external boost (vs PIC24FJ64GC006-I/PT)
Design Notes
Estimated power budget for a metering application at 3.0 V VDD: CPU active at 32 MHz draws ~7 mA (per 'GL' family datasheet); XLP sleep with RTCC and RAM retention drops to ~300 nA. Duty-cycle calculation for 1% active time yields average current of ~70 uA, supporting 10+ years from a 2.4 Ah Li-SOCl2 primary cell. Use the integrated charge pump only when the LCD contrast voltage exceeds the VDD rail; otherwise disable it to save ~50 uA quiescent draw.
The 28-QFN (6x6) package requires a thermal pad soldered to a ground pour on the top PCB layer to meet the E-grade thermal envelope. Place decoupling 100 nF and 4.7 uF ceramic capacitors within 2 mm of the VDD and VSS pins. For LCD applications, route the COM and SEG traces away from switching power sections to avoid display ghosting. Microchip's 'GL' family board design checklist (AN1416) provides reference PCB layouts for LCD glass connection.
Do not exceed the 3.6 V absolute maximum VDD, or the LCD charge pump and EEPROM will suffer permanent damage. When migrating from 'GL' to 'GC' family variants, verify the pinout - the GC006 family uses different pin assignments for the LCD charge pump pins. Always check the device errata document before committing to production, as the 'GL' family has known revisions affecting the RTCC drift behavior at temperatures above 85 °C.
Compliance Information
AEC-Q100 qualified per GlobalSpec listing. RoHS compliant per Microchip product page. Halogen-free status not explicitly listed in verified data.
