Overview

The PIC18F65K40T-I/MR is an 8-bit microcontroller featuring 32KB of Flash memory and 2KB of RAM, operating at speeds up to 64MHz. Part of the PIC18 K40 family, it incorporates eXtreme Low-Power (XLP) technology and a wide range of Core Independent Peripherals (CIPs) to reduce CPU overhead. With 60 I/O pins in a compact 64-VQFN package, it is designed for applications requiring high pin counts and low power consumption.

Why Choose This Part

This MCU offers a high I/O-to-memory ratio, providing 60 GPIOs despite its modest 32KB Flash size. The inclusion of 1KB of dedicated EEPROM allows for robust non-volatile data storage without using Flash endurance, while the Peripheral Pin Select (PPS) feature simplifies PCB routing by allowing flexible pin mapping.

Applications

Industrial Control Systems
Utilizing 60 I/O pins for monitoring sensors and controlling actuators in automation environments.
Battery-Powered Handheld Devices
Leveraging XLP technology and 50uA sleep currents to extend battery life in portable instrumentation.
Automotive Interior Electronics
Integrating LINbus connectivity and PWM modules for lighting control and cabin monitoring.
Home Automation Gateways
Managing multiple communication interfaces including I2C, SPI, and UART for local sensor networking.

Getting Started

Begin development using the MPLAB X IDE and the XC8 compiler. Use the Curiosity High Pin Count (HPC) Development Board or a custom PCB paired with an MPLAB ICD 4 or PICkit 4 programmer/debugger. The MPLAB Code Configurator (MCC) is highly recommended for initializing the 64MHz internal oscillator and mapping the Peripheral Pin Select (PPS) registers.
