PIC18F67J50-I/PT

The PIC18F67J50-I/PT is Microchip’s USB-enabled PIC18 8-bit microcontroller. It is designed for USB device applications and integrates a full-speed USB 2.0 interface (12 Mbps) plus a versatile set of on‑chip peripherals. Typical features include a PIC18 core running up to a system clock derived for USB, on‑chip flash/program memory, RAM, EEPROM, and peripherals such as USART, SPI, I2C, multiple timers, PWM channels, and an analog-to-digital converter. The -I suffix indicates industrial temperature range (-40°C to +85°C), and the /PT suffix denotes a plastic package suitable for tape-and-reel packaging. This device is well-suited for USB HID, CDC (virtual COM), MIDI, custom USB peripherals, and data‑acquisition applications. Development is supported by Microchip’s tools (MPLAB X IDE, XC8 compiler, USB Device libraries, MCC) and standard programmers/debuggers (PICkit, ICD). For exact memory sizes, pin count, packaging, and USB capabilities, consult the latest PIC18F67J50 datasheet and family reference manuals.
