Key Features
- Up to 40 MHz clock from a 2.0 V to 5.5 V supply enables low-power and 5 V system designs on the same silicon
- 96 KB Flash memory and 10-bit multi-channel ADC suit data-logging, sensor-interfacing, and embedded control
- 64-pin TQFP with boundary scan support simplifies board-level testing and provides extensive peripheral I/O connectivity
Applications
The PIC18LF6493-I/PT is used in embedded control systems, industrial data loggers, and sensor-interface boards requiring an 8-bit processor with a broad I/O count and analog capability. Its 2.0 V to 5.5 V supply range suits both battery-powered portable instruments and 5 V industrial control boards without hardware redesign. The industrial temperature rating of -40°C to +85°C and boundary scan support make it well suited for demanding field-deployed and production-tested applications.

Frequently Asked Questions
How does the PIC18LF6493's 2.0 V minimum operating voltage extend battery life in portable instrument designs?
The PIC18LF6493 operates down to 2.0 V at 4 MHz, continuing to function as alkaline or lithium cells discharge below the 3.3 V threshold that would halt higher-voltage microcontrollers. This wide 2.0 V to 5.5 V range extracts more usable capacity from 2-cell AA or 3 V coin-cell packs in portable data loggers and handheld instruments.
For a multi-sensor data acquisition board, how many analog inputs does the PIC18LF6493 provide and at what resolution?
The PIC18LF6493 integrates a 10-bit ADC with up to 12 analog input channels, enabling simultaneous monitoring of multiple temperature, pressure, or current sensors in a single-chip design. At up to 40 MHz clock speed, conversion results can be processed fast enough for real-time control loops across the -40°C to +85°C industrial temperature range.
When is the PIC18LF6493-I/PT a better choice than a 32-bit microcontroller for a cost-sensitive embedded control design?
The PIC18LF6493-I/PT is preferable when the application fits within 8-bit arithmetic, requires fewer than 12 analog channels, and benefits from a mature PIC18 ecosystem with compact 40 MHz performance in a 64-pin TQFP at a lower unit price than 32-bit alternatives. Its minimal 2.0 V start-up voltage and extensive peripheral set reduce external component count in cost-sensitive industrial controllers.
