- Pb-free RoHS-compliant TQFP-80 packaging supporting automated SMT assembly in high-reliability industrial and automotive-adjacent designs
Applications
The PIC18LF8628-I/PT targets demanding industrial control systems such as multi-axis motor controllers, industrial PLCs, and smart energy meters that require large Flash, high I/O count, and low-power standby capability. Its eXtreme Low Power (XLP) technology extends battery backup duration in equipment that must retain state during power outages. The 80-pin TQFP package provides sufficient GPIO and peripheral pins to connect sensors, actuators, communication interfaces, and display modules in a single-chip design.

Frequently Asked Questions
How much Flash memory does PIC18LF8628-I/PT provide and is it enough for a CAN-plus-Modbus dual-protocol firmware stack?
The PIC18LF8628-I/PT provides 96 KB of Flash program memory, which is ample to hold a CAN 2.0B driver, a Modbus RTU stack, application logic, and a bootloader simultaneously — a typical dual-protocol embedded firmware image fits comfortably within 60 KB to 80 KB on an 8-bit PIC18 core running at 40 MHz.
What is the maximum clock frequency of PIC18LF8628-I/PT and how does XLP technology benefit a battery-backed application?
The device runs up to 40 MHz and its eXtreme Low Power (XLP) architecture reduces sleep current to below 100 nA, extending a 100 mAh coin-cell backup battery life from days to years in data-logging equipment that wakes periodically, takes a reading, and returns to deep sleep.
For a 64-channel analog data acquisition front-end, how does PIC18LF8628-I/PT's 80-pin TQFP package simplify board design?
The 80-pin TQFP-80 exposes enough GPIO to drive a 16-to-1 analog multiplexer selection matrix plus UART, SPI, and I2C buses simultaneously, reducing external logic from 4 shift registers to 0 and shrinking the PCB layer count from 4 to 2 in a typical 64-channel acquisition front-end design.
Does PIC18LF8628-I/PT include on-chip DAC capability, and for what signal-generation use cases is that relevant?
Yes, the device integrates a DAC alongside the multi-channel ADC, enabling closed-loop analog control where the MCU both reads a sensor output and generates a reference or correction voltage on-chip, as required in precision current-loop 4 mA to 20 mA industrial transmitters and programmable-gain amplifier bias circuits.
