1.6.5 VT1211 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).
