MCHPPIC18F27K40-I/SP
Overview
The PIC18F27K40-I/SP is a high-performance 8-bit microcontroller featuring 128KB of Flash memory and 3.6KB of RAM in a breadboard-friendly 28-pin SPDIP package. Part of the PIC18 K40 family, it integrates eXtreme Low Power (XLP) technology with a robust set of Core Independent Peripherals (CIPs) to handle timing and control tasks with minimal CPU intervention.
Why Choose This Part
This MCU offers a massive 128KB Flash capacity for an 8-bit device, accommodating complex logic and large look-up tables. The inclusion of Peripheral Pin Select (PPS) allows engineers to map digital peripherals to any I/O pin, greatly simplifying PCB layout and routing.
Applications
Key Specifications
Getting Started
Develop using the Microchip MPLAB X IDE and the XC8 C Compiler. For hardware programming and debugging, use the MPLAB PICkit 4 or Snap in-circuit debugger connected to the ICSP pins. The Curiosity Development Board (DM164137) is the recommended evaluation platform for this family.
