- 8-bit PIC18 CPU core running up to 40 MHz with integrated Flash program memory for embedded control
- On-chip ADC for direct analog sensor signal acquisition without external converter ICs
- Extended temperature range (-40°C to +125°C) for industrial and harsh-environment designs
- 44-pin TQFP package providing ample I/O in a standard QFP surface-mount footprint
- Pb-free, RoHS-compliant construction with short 6-week factory lead time for supply chain flexibility
Applications
PIC18F4682-E/PT is used in industrial control panels, building automation, motor drive systems, and embedded sensing applications where an 8-bit MCU with analog input capability and extended temperature range (-40°C to +125°C) is required. Its mature PIC18 architecture integrates well with Microchip's MPLAB development ecosystem, reducing firmware development time for production designs. The 44-pin TQFP package suits mid-density PCB designs requiring more I/O than 28-pin variants without the cost of a larger 64-pin or 80-pin package.

Frequently Asked Questions
How does PIC18F4682-E/PT perform in industrial control applications requiring operation across extreme temperatures?
PIC18F4682-E/PT carries the -E temperature grade, covering -40°C to +125°C, which qualifies it for harsh industrial and automotive-adjacent environments. Running at up to 40 MHz and supporting ADC acquisition, it handles sensor polling and control loops reliably across the full industrial temperature range without derating the clock to achieve compliance.
What analog measurement capability does the on-chip ADC provide for sensor interface designs?
The PIC18F4682-E/PT integrates an ADC that allows direct digitization of analog sensor outputs such as temperature, pressure, or position signals, eliminating the need for an external ADC IC. This reduces BOM cost and PCB complexity in data logging, HVAC control, and industrial automation designs requiring multiple analog input channels.
Why might a designer choose the 44-pin TQFP package of PIC18F4682-E/PT over a 28-pin DIP alternative?
The 44-pin TQFP package provides more I/O pins and a smaller surface-mount footprint than a 28-pin PDIP, enabling higher pin count for GPIO, communication peripherals, and analog inputs in a compact PCB layout. Standard TQFP-44 land patterns are compatible with automated SMT assembly, reducing hand-soldering risk in medium-volume and high-volume production runs.
What is the typical factory lead time for PIC18F4682-E/PT, and how should procurement teams plan inventory for it?
PIC18F4682-E/PT has a 6-week factory lead time, which is relatively short for a specialty MCU. Procurement teams can typically order to near-term demand with a modest safety stock buffer of 4–8 weeks of consumption, reducing the carrying cost of excess inventory while protecting against short-term supply fluctuations.
