Overview

The PIC18F26K42-I/SS is an 8-bit microcontroller that balances high performance with low power consumption, featuring 64KB of Flash memory and a 64MHz internal clock. It is part of the PIC18-K42 family, which focuses on Core Independent Peripherals (CIPs) to handle hardware tasks without CPU intervention. This specific variant is housed in a 28-pin SSOP package, providing 25 I/O pins for space-constrained embedded designs.

Why Choose This Part

This MCU excels due to its Core Independent Peripherals and a Direct Memory Access (DMA) controller, which significantly improves data throughput compared to standard 8-bit devices. It includes a 1K x 8 EEPROM for robust non-volatile storage and supports a 31-level hardware stack for complex firmware execution.

Applications

Automotive Control Modules
Utilizing the LINbus and UART interfaces for cabin electronics or sensor monitoring.
Sensor Fusion Hubs
Aggregating data from multiple I2C and SPI sensors using the integrated DMA to reduce CPU overhead.
Power Management Systems
Implementing safety features like the Windowed Watchdog Timer (WWDT) and Brown-out Reset for reliable voltage monitoring.
Industrial Protocol Converters
Acting as a bridge between serial peripherals and higher-level controllers using its flexible connectivity options.
