This document details the SMSC LPC47N217, a highly integrated 64-pin Super I/O controller designed for modern computing systems. It features a 3.3V operation with 5V tolerance on non-LPC pins, supporting PC 99, PC2001, and ACPI 2.0 standards.
The LPC47N217 leverages the LPC interface for reduced pin count while maintaining high performance, comparable to ISA/X-bus architectures.
Key Features:
- 3.3V Operation (5V tolerant on non-LPC pins)
- LPC Interface
- 16C550A Compatible UART
- Multi-Mode Parallel Port (SPP, EPP, ECP) with ChiProtect™
- Infrared Communications Controller (IrDA v1.2, HPSIR, ASKIR)
- 14 General Purpose I/O (GPIO) pins
- Power Management Events (PME/SMI) support
- Intelligent Auto Power Management
This datasheet provides comprehensive information on the LPC47N217's features, pinout, functional descriptions, and electrical characteristics, serving as a vital resource for system designers and engineers.
