Overview

The PIC18F45K22-I/PT is a high-performance 8-bit microcontroller featuring 32KB of Flash memory and a 64MHz maximum clock speed. It belongs to the PIC18K22 family and offers a balanced feature set including a hardware multiplier, 256 bytes of EEPROM, and a wide operating voltage range. This TQFP-44 device is designed for general-purpose embedded applications requiring a C-optimized architecture and low power consumption.

Why Choose This Part

The microcontroller provides 64MHz performance via an internal PLL and 16MHz oscillator, eliminating the need for external crystals in many designs. It features a robust peripheral set including 31-level hardware stack and priority interrupts, which simplifies real-time task management. The single-cycle 8x8 hardware multiplier significantly accelerates math-intensive firmware compared to standard 8-bit cores.

Applications

Industrial Sensor Interfaces
Utilizes the integrated ADC with auto-acquisition and the Fixed Voltage Reference for precise analog sensor measurements.
Communication Bridges
Leverages multiple UART, SPI, and I2C interfaces to act as a gateway between different serial communication protocols.
Low-Power Monitoring
Ideal for battery-operated devices using Sleep and Idle modes, with current consumption as low as 20uA in shutdown.
System Logic Controllers
Uses its 35 I/O pins and hardware PWM modules to manage system-level logic and basic motor or lighting control.

Getting Started

Development is primarily supported through Microchip MPLAB X IDE and the XC8 C Compiler. For hardware debugging and programming, the MPLAB PICkit 4 or MPLAB ICD 4 probes are recommended via the ICSP interface. Evaluation can be performed using the Curiosity Development Board or by designing a custom PCB based on the 44-pin TQFP footprint.
