Overview

The PIC18F45K22-I/MV is a high-performance 8-bit microcontroller featuring Microchip XLP technology for ultra-low power consumption. It operates at up to 64MHz and integrates 32KB of Flash memory with a robust set of analog and digital peripherals in a space-saving 40-UQFN package.

Why Choose This Part

This MCU offers a C-compiler optimized architecture with a hardware 8x8 multiplier for efficient math operations. The inclusion of on-chip EEPROM and a 5-bit DAC simplifies bill-of-materials by reducing the need for external memory and basic analog components.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology and Sleep modes to extend battery life in wireless monitoring nodes.
Industrial Control Panels
Leverages the hardware multiplier and multiple UART/SPI/I2C interfaces for local processing and communication.
Portable Medical Devices
Provides integrated ADC and DAC peripherals for sensor signal conditioning in handheld diagnostic tools.
Automotive Body Electronics
Suitable for non-safety critical cabin controls requiring low standby current and reliable 8-bit processing.
