Overview

The PIC18F67J50-I/PT is a high-performance 8-bit microcontroller from Microchip's 18J family, featuring 128KB of Flash memory and an integrated Full-Speed USB 2.0 interface. It is designed for cost-sensitive applications requiring USB connectivity, offering 49 I/O pins and 10-bit A/D converters in a 64-TQFP package. This MCU utilizes nanoWatt Technology to minimize power consumption in battery-operated systems.

Why Choose This Part

The part features a C-compiler optimized architecture with an 8x8 hardware multiplier for efficient math operations. It offers 5V tolerant digital inputs even when operating at a 3.3V VDD, simplifying logic interfacing in mixed-voltage systems. Additionally, the deep sleep and idle modes achieve current consumption as low as 0.5uA to 1.4uA, making it highly competitive for power-constrained designs.

Applications

USB Peripheral Devices
Ideal for creating USB-to-Serial bridges, human interface devices (HID), or custom data acquisition tools using the integrated USB SIE.
Industrial Data Loggers
Utilizes the 128KB Flash and multiple serial interfaces (SPI/I2C/USART) to collect and store sensor data for later retrieval via USB.
Handheld Medical Instruments
Leverages nanoWatt power management and a 2.5V on-chip regulator to extend battery life in portable monitoring equipment.
Parallel Port Expansion
The built-in Parallel Master Port (PMP) allows for high-speed communication with external memory or LCD controllers.

Getting Started

To begin development, use the MPLAB X IDE and the MPLAB XC8 compiler. Hardware debugging and programming are supported via the PICkit 4 or MPLAB ICD 4 using the In-Circuit Serial Programming (ICSP) interface. Microchip's Libraries for Applications (MLA) provide the necessary USB stacks and drivers to quickly implement USB functionality.
