- Integrated LCD segment driver eliminating the need for an external display controller IC
- XLP (eXtreme Low Power) mode enabling sub-µA sleep currents for battery-backed meter and sensor designs
- VBAT pin for real-time clock backup power during main supply interruption
- DMA channels offloading data transfers from the CPU for efficient peripheral data handling
- 100-pin TQFP package offering rich GPIO count for large panel and multi-peripheral board designs
What is PIC24FJ128GA310-I/PF used for?
The PIC24FJ128GA310-I/PF is designed for LCD-interfaced products such as smart electricity meters, gas meter displays, HVAC thermostats, and industrial panel controllers where an on-chip segment LCD driver reduces BOM complexity. Its XLP ultra-low-power mode and VBAT backup make it well suited for battery-operated portable instruments that must retain RTC data through power outages. DMA support and 128 kB Flash also enable communication-heavy applications such as building automation nodes with simultaneous serial, SPI, and I2C traffic.

Frequently Asked Questions
Does the PIC24FJ128GA310-I/PF include an on-chip LCD driver and how many segments can it drive?
Yes. The PIC24FJ128GA310-I/PF integrates an LCD segment driver capable of driving multiple static and multiplex LCD displays. This eliminates a separate LCD controller IC from the BOM and reduces I2C or SPI bus traffic, simplifying firmware for smart meter front-panel and thermostat display designs.
How much Flash and RAM does the PIC24FJ128GA310-I/PF provide and is it enough for a Modbus RTU stack alongside application code?
The device provides 128 kB Flash and 8 kB RAM. A compact Modbus RTU stack typically consumes under 10 kB Flash and under 1 kB RAM, leaving over 118 kB Flash and 7 kB RAM for the LCD driver, application logic, and communication buffers — ample headroom for most industrial meter and controller firmware.
What power saving does the XLP mode provide and how does VBAT support keep the RTC running during power loss?
In XLP sleep mode, the PIC24FJ128GA310-I/PF can reduce supply current to below 1 µA, extending battery life in always-on metering applications. The VBAT pin accepts a separate coin cell or supercapacitor supply that keeps the real-time clock and SRAM alive during main power failure, maintaining accurate timekeeping without reinitialization.
What pin count and package does the PIC24FJ128GA310-I/PF use, and what PCB footprint area does a 100-pin TQFP require?
The PIC24FJ128GA310-I/PF is housed in a 100-pin TQFP package with a 14 mm × 14 mm body and 0.5 mm pin pitch. This compact footprint fits on standard 2-layer or 4-layer PCBs and provides 100 pins for GPIO, communication, ADC, and LCD segment connections in a single device.
