Overview

The PIC18F25K50-I/SS is an 8-bit microcontroller featuring eXtreme Low Power (XLP) technology and a full-speed USB 2.0 interface. It operates at up to 48MHz and includes 32KB of flash memory, making it suitable for cost-effective USB peripheral designs that require minimal power consumption. The device integrates a precise internal oscillator, eliminating the need for external crystals in many USB applications.

Why Choose This Part

This MCU offers a 5V tolerant I/O range and high drive capability of up to 25mA per pin, simplifying interfacing with various logic levels. The C-optimized architecture and 8x8 hardware multiplier improve execution efficiency for 8-bit math-intensive tasks while maintaining low power profiles across Run, Idle, and Sleep modes.

Applications

USB Peripheral Devices
Ideal for human interface devices (HID) such as keyboards, mice, and custom controllers using the integrated USB 2.0 transceiver.
Battery-Powered Instrumentation
Utilizes XLP technology for sleep currents as low as 20nA, extending life in remote sensing and handheld tools.
Industrial Data Loggers
Employs 256 bytes of internal EEPROM for non-volatile storage of calibration data and system parameters.
Communication Bridges
Functions as a protocol converter between USB and legacy UART, SPI, or I2C serial interfaces.
