1.6.5VT1211 Super I/O

The VT1211 is a full function Super I/O chip that provides the most commonly used legacy Super I/O functionality plus the latest Hardware monitor initiatives. The device uses an LPC interface that complies with “LPC Interface Specification Revision 1.0”.

The VT1211 contains a Floppy Disk Controller, an IEEE-1284 Parallel Port interface, two 16C550-UART-based serial port interfaces, a VFIR (Very Fast IR) Controller, a game port which supports 2 joysticks, a MIDI interface and a 4M Flash-ROM interface. The integrated Hardware Monitor Controller controls the speed of 2 fans, monitors 2 fan tachometers and has a Pentium II thermal diode and 5 Universal analog inputs for measuring voltage or temperature (by connecting external thermistors). The VT1211 meets the “Microsoft PC98

&PC99 system design guide” requirements and is ACPI ready. The device requires a 48 MHz clock input and operates at 3.3V power supply.

The VT1211 consists of following logical devices. One high-performance 2.88MB floppy disk controller, with digital data separator, which supports one 360K / 720K / 1.2M / 1.44M / 2.88M floppy disk drive; One multi-mode high-performance parallel port featuring support for bi-directional Standard Parallel Port (SPP), Enhanced Parallel Port (EPP v1.7 and v1.9) and IEEE1284 compliant Extended Capabilities Port (ECP) protocols; Two 16C550 standard compatible enhanced UARTs perform asynchronous communication; One VFIR interface compliant with IrDA; One MIDI interface; One game port with built-in 558 and buffer chips to support direct connect of 2 joysticks; One Hardware Monitor; and Seven GPIO ports (56 GPIO pins).
