It can be used in various computing devices with reduced pin counts, making it an ideal choice for space-constrained designs.

Comparison

• Operates on 3.3 volts which makes it highly power-efficient.
• Compliant with PC98/PC99 and uses the LPC interface, which is a pin-reduced ISA bus interface with better performance.
• Provides two fan speed control output pins and two fan tachometer input pins, making it perfect for fan control.
• Provides 37 general-purpose input/output (GPIO) pins for versatile functionality.
• Supports a dual-game port interface and MPU-401 MIDI support for enhanced audio and gaming support.

• The 100-pin QFP package might not fit in every design, particularly space-constrained ones.
• While it does provide a range of interfaces and functionalities, it may not suit certain applications where specific features are required.
