Key Features
- 128 KB ECC flash with hardware error correction: safeguards firmware integrity against single-bit memory errors in safety-critical and long-deployed embedded systems
- Integrated USB 2.0 full-speed OTG and LCD segment driver: combines display control and USB connectivity in a single TQFP-80 chip for panel-mounted instruments and meters
- 16-bit PIC24FJ core at 48 MHz (16 MIPS) with 32 KB RAM: provides efficient signal processing headroom for graphical UI, protocol stacks, and sensor fusion without an external SRAM
Applications
The PIC24FJ128GU408-I/PT is designed for panel-mounted industrial instruments, energy meters, and medical monitoring devices that require simultaneous USB communication, LCD segment display driving, and analog signal conditioning from its 17-channel 10-bit ADC. Its 128 KB ECC flash ensures data integrity across long product lifetimes in deployed equipment where firmware corruption from single-event upsets must be detected and corrected automatically. The 80-pin TQFP package provides ample I/O for complex peripheral configurations including multiple UART, SPI, and I2C interfaces alongside the LCD and USB buses.

Frequently Asked Questions
What is the significance of ECC flash in the PIC24FJ128GU408-I/PT for safety-critical applications?
The PIC24FJ128GU408-I/PT features 128 KB of flash with hardware Error Correction Code (ECC) that automatically detects and corrects single-bit errors in program memory, which is essential in medical, industrial, and metering applications where firmware corruption could cause dangerous behavior or measurement errors over a product lifetime of 10 or more years.
Which display and connectivity peripherals does the PIC24FJ128GU408-I/PT integrate on a single chip?
The PIC24FJ128GU408-I/PT integrates a USB 2.0 full-speed On-The-Go (OTG) controller supporting both host and device modes, an LCD segment driver capable of driving multi-digit displays, and a 17-channel 10-bit ADC, allowing designers to build a complete meter or instrument front-end in a single TQFP-80 package without external display driver ICs.
How does PIC24FJ128GU408-I/PT compare to a PIC24FJ64GU405 when evaluating firmware size headroom for a panel meter upgrade?
The PIC24FJ128GU408-I/PT provides 128 KB ECC flash and 32 KB RAM versus the PIC24FJ64GU405's 64 KB flash and 8 KB RAM, doubling both program and data memory while maintaining the same PIC24FJ core running at 48 MHz (16 MIPS), making the GU408 a natural upgrade for panel meter designs where a full Modbus stack, USB logging, and multi-screen LCD UI exceed the 64 KB code budget.
