Overview

The PIC18F87K22-I/PT is a high-performance 8-bit microcontroller featuring 128KB of Flash memory and integrated eXtreme Low Power (XLP) technology. It operates at speeds up to 64MHz and includes a rich set of peripherals such as an External Bus Interface (EBI) and multiple serial communication channels. This 80-pin TQFP device is designed for applications requiring high I/O density and extensive memory in a power-constrained environment.

Why Choose This Part

This MCU offers a balance of high-density I/O (69 pins) and large program memory for an 8-bit architecture. It excels in power management with a 1us fast wake-up time and extremely low input leakage of 50nA. Additionally, the 1024 bytes of high-endurance EEPROM provide robust non-volatile storage for calibration data and user settings.

Applications

Remote Industrial Sensors
Utilizes XLP technology for multi-year battery life in remote monitoring stations using low-power wake-up and 20uA sleep modes.
Portable Medical Devices
The 128KB Flash and 4KB RAM support complex algorithms for handheld diagnostic tools while maintaining low power consumption.
Home Automation Gateways
Leverages 69 I/O pins and multiple UART/I2C interfaces to coordinate communication between various smart home peripherals.
Electronic Door Locks
Reliable operation using the integrated Power-on Reset, Watchdog Timer, and low-power hardware for secure access control.
