SUPER P5MMA98/P5MMS98/P5MMA2/P5MMS2 User’s Manual
1-6 Super I/O Controller
SUPER P5MMA98/P5MMA2 uses National Semiconductor 87307
Super I/O Controller which incorporates an IDE control logic, two full
function serial ports, an IEEE 1284 parallel port, industry standard
floppy disk controller with 16 byte FIFO, Real Time Clock and an
8042 compatible keyboard controller all in one chip.
The IDE interface provides ultra-DMA control up to 33 MB/s. The
two serial ports are software compatible with the Fast UART 16550.
The parallel port is EPP (Enhanced Parallel Port) and ECP (Ex-
tended Capabilities Port) compatible, including level 2 support. It
includes a protection circuit against damage caused when the
printer is powered up. EPP mode provides for greater throughput
than Compatible or Extended modes by supporting faster transfer
rates and a mechanism that allows the host to address peripheral
device registers directly. Faster transfers are achieved by automati-
cally generating the address and data strobes. EPP is compatible
with both Compatible and Extended mode parallel-port devices.
SUPER P5MMS98/P5MMS2 uses the Winbond W83967AF Super I/O
Controller which integrates W83877AF Winbond I/O, RTC (Real
Time Clock) with Advanced Power Management, W83C45 keyboard
controller with PS/2 mouse support, 14 general purpose I/O ports,
two serial ports, a serial infrared port, and ISA plug-and-play stan-
dard (version 1.0a) in 160 pin QFP.
The wide range of functions integrated onto the W83967AF greatly
reduces the number of components required to interface with floppy
disk drives. There are three high-speed serial communication ports
(UARTs) on it. The UARTs include 16-byte send/receive FIFOs, a
programmable baud rate generator, complete modem control capa-
bility, and a processor interrupt system. The parallel port supports
standard parallel port, IEEE 1284 EPP and ECP.
