PIC24FJ128GL305-I/M4 - 16-bit 128KB LCD MCU | Microchip
MPN: PIC24FJ128GL305-I/M4 ✓ فعالPIC24FJ128GL305-I/M4 جائزہ
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.

عام استعمالات
PIC24FJ128GL305-I/M4 کے لیے موزوں ہے 6 ایپلیکیشنs: 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.

ڈیزائن نوٹس
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.
