W311 Overview
Open-drain system reset output. (opendrain) O I O CPU Clock Output: Frequency is set by the FS0:4 input or through serial input interface.
W311 Key Features
- Maximized EMI Suppression using Cypress’s Spread Spectrum Technology
- System frequency synthesizer for VIA Pro-2000
- Programmable clock output frequency with less than 1 MHz increment
- Integrated fail-safe Watchdog Timer for system recovery
- Automatically switch to HW selected or SW programmed clock frequency when Watchdog Timer time-out
- Capable of generate system RESET after a Watchdog Timer time-out occurs or a change in output frequency via SMBus interf
- Support SMBus byte read/write and block read/ write operations to simplify system BIOS development
- Vendor ID and Revision ID support
- Programmable drive strength for CPU and PCI output clocks
- Programmable output skew between CPU, AGP and PCI
