Overview

The PIC18F67J94-I/PT is a high-performance 8-bit microcontroller from Microchip's XLP (eXtreme Low Power) family, featuring 128KB of Flash and a dedicated USB 2.0 interface. It integrates an on-chip LCD controller and a 12-bit ADC, making it suitable for segmented display applications and precision sensor interfacing. The device operates at up to 64MHz and includes specialized power modes like Deep Sleep and VBAT for battery-critical designs.

Why Choose This Part

This MCU offers a unique combination of 12-bit analog precision and USB connectivity within the 8-bit PIC18 architecture. Its XLP technology achieves sleep currents as low as 70nA, while the internal oscillator with clock recovery simplifies BOM by eliminating external timing components for USB applications.

Applications

Handheld Medical Devices
Utilizes the integrated LCD driver and 12-bit ADC for portable diagnostic tools requiring long battery life.
USB Peripheral Controllers
Leverages the internal high-precision clock recovery for USB communication without the need for an external crystal.
Smart Utility Meters
Uses the VBAT pin and Real-Time Clock/Calendar (RTCC) to maintain timekeeping and data integrity during primary power loss.
Industrial Data Loggers
Employs the 128KB Flash and Charge Time Measurement Unit (CTMU) for capacitive sensing and environmental monitoring.

Getting Started

Development is supported by the MPLAB X IDE and the XC8 compiler. For hardware evaluation, the PIC18 Explorer Development Board (DM183032) combined with a PIM (Plug-In Module) is the standard path. A PICkit 4 or MPLAB ICD 4 debugger is recommended for programming via the ICSP interface.
