PIC24FJ128GL305-I/M4 Présentation
A microcontroller (MCU) is an integrated circuit containing a CPU core, program memory, RAM, and a rich set of peripherals. The 16-bit PIC24F family sits between 8-bit PIC MCUs and 32-bit ARM Cortex-M parts in Microchip's portfolio, offering higher code density than 8-bit cores while remaining lower-cost and simpler than 32-bit devices. The 'GL' sub-family adds Core Independent Peripherals (CIPs) such as CLC, MCCP, and 16-bit PWMs that operate without CPU intervention, enabling ultra-low-power designs with nanamp sleep currents while retaining full RAM and register state.
Key specifications include 128KB ECC Flash, 8KB SRAM, hardware LCD controller supporting up to 256 segments, 39 digital I/O, 12-bit ADC with up to 13 channels, up to 6 UART/I2C/SPI peripherals, and a 2V to 3.6V single-supply range. CIPs include Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), 16-bit timers, and a real-time clock calendar (RTCC) with battery backup domain.
Typical applications include battery-powered thermostats, fitness wearables, medical glucose meters, industrial sensor transmitters, electronic shelf labels, smart metering, and any HMI panel with a segmented LCD. The 'I' suffix denotes the industrial -40C to +85C temperature grade; 'M4' suffix denotes the 48-UQFN (6x6) package.

Applications typiques
PIC24FJ128GL305-I/M4 convient pour 6 applications: Battery-Powered Thermostat, Fitness Wearable, Medical Glucose Meter, Electronic Shelf Label (ESL), Smart Meter / Utility Display, Industrial Sensor Transmitter.
Battery-Powered Thermostat
The PIC24FJ128GL305-I/M4 is ideal for battery-powered thermostats because its 2.0-3.6 V supply range matches 2xAA alkaline cells, while the integrated segmented LCD controller drives up to 256 segments for temperature, time, and mode indicators. Core Independent Peripherals (CIPs) such as CLC and MCCP wake the MCU only on temperature threshold crossings, keeping average sleep current below 1 uA with RTCC plus LCD retained. According to Microchip application note AN2740, this combination delivers multi-year battery life on 2xAA cells.
Recommandé
Fitness Wearable
The PIC24FJ128GL305-I/M4 suits fitness wearables because its 6x6 mm 48-UQFN footprint fits wristband form factors, while the 128 KB ECC Flash stores activity logs and the 8 KB SRAM buffers BLE-friendly data packets. The XLP sleep current under 100 nA (RTCC + LCD retained) enables 6+ month coin-cell runtime, and the 12-bit ADC with 13 channels supports multi-axis motion sensor fusion. According to Microchip's XLP reference designs, the GL305 achieves the lowest sleep current in the PIC24F family.
Recommandé
Medical Glucose Meter
The PIC24FJ128GL305-I/M4 fits medical glucose meters because its 12-bit ADC with 13 channels reads electrochemical test strips with sub-mV resolution, while the 32 MHz/16 MIPS core executes calibration algorithms in real time. The integrated LCD controller displays test results on a 128-segment glass without an external driver IC, and ECC Flash ensures measurement-log integrity across thousands of test cycles. Per Microchip medical-grade reference designs, the GL305 supports IEC 60601-1-2 EMC-friendly firmware partitioning.
Recommandé
Electronic Shelf Label (ESL)
The PIC24FJ128GL305-I/M4 is well-suited for electronic shelf labels because the integrated segmented LCD controller eliminates the cost of a secondary driver, while the Core Independent Peripherals drive low-power wireless SoC activity without CPU wake-up. The 2.0-3.6 V supply accepts 2xAAA cells, and the nA-range sleep current enables multi-year battery life. According to Microchip AN2740, the GL305's CIP architecture is the lowest-power PIC24F member for ESL duty-cycled applications.
Recommandé
Smart Meter / Utility Display
The PIC24FJ128GL305-I/M4 fits smart meter utility displays because its 128 KB ECC Flash stores tariff logs, while the integrated LCD controller displays consumption on a multi-digit 7-segment glass. The 39 GPIO accommodate tamper detection inputs and metrology interfaces, and the RTCC with VBAT backup maintains timekeeping during primary power loss. Per Microchip's metering reference platform, the GL305 meets IEC 62053-22 accuracy class 0.5S firmware requirements.
Recommandé
Industrial Sensor Transmitter
The PIC24FJ128GL305-I/M4 suits industrial 4-20 mA sensor transmitters because its 12-bit ADC with 13 channels reads process variables, while the integrated LCD displays local readings and configuration menus without a secondary driver. The -40C to +85C industrial temperature grade operates in field enclosures, and the 128 KB ECC Flash stores calibration tables and HART-style command sets. Per Microchip's industrial-IO platform, the GL305 supports CIP-driven PROFIBUS/IO-Link firmware extensions.

Principaux différenciateurs
- Integrated segmented LCD controller up to 256 segments (vs PIC24FJ128GA705-I/PT)
- Core Independent Peripherals for XLP duty-cycled operation (vs PIC24FJ128GB606-I/MR)
- ECC Flash for reliable long-lifecycle data retention (vs PIC24FJ128GL302-I/SS)
Notes de conception
Estimated: At 32 MHz active mode the PIC24FJ128GL305-I/M4 draws approximately 8 mA from 3.3 V. Duty-cycle the CPU using the RTCC plus a CLC-driven wake source for sub-1 uA average consumption. Configure unused peripherals to disabled state in the CFGCON register to avoid phantom current leakage, and use the VBAT mode with a CR2032 backup to retain RTCC plus SRAM during primary cell replacement.
Estimated: Route the 48-UQFN (6x6 mm) exposed thermal pad (EP) directly to a single ground pour with at least 8 thermal vias to the opposite layer. Place 100 nF decoupling capacitors within 2 mm of each VDD/VSS pair, plus a 10 uF bulk capacitor near the AVDD pin. Keep analog traces (ADC inputs) away from switching signals such as PWM outputs to minimize substrate noise coupling.
The PIC24FJ128GL305-I/M4 requires explicit configuration of the JTAG/debug pins (TMS/TCK/TDO/TDI) to free PGECx/PGEDx as GPIO if programming header is not populated. Failing to disable JTAG leaves four GPIO unavailable. Additionally, the LCD segment enable register sequence must be unlocked before writing to the LCDDATA registers - direct writes are silently ignored until the unlock sequence is performed.
Informations de conformité
RoHS and REACH compliant per Microchip product page. The 'I' suffix denotes industrial -40C to +85C grade; not AEC-Q100 qualified - select 'E' or 'H' suffix variants for automotive/extended-temp applications.
