SMSC DS – LPC47M192
Page 3
Rev. 03/30/05
DATASHEET
GENERAL DESCRIPTION
The LPC47M192 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant Super I/O controller with an LPC
interface and Hardware Monitoring capabilities.
The LPC47M192’s hardware monitoring capability includes voltage and temperature monitoring with the ability to
alert the system of out-of-limit conditions. There are 7 analog inputs for monitoring external voltages of +1.5V, +1.8V,
+2.5V, +3.3V, +5V, +12V and Vccp (core processor voltage), as well as internal monitoring of the devices own HVCC
or HVSB. The LPC47M192 includes support for monitoring two external temperatures via thermal diode inputs and an
internal sensor for measuring ambient temperature. The nTHERM pin is implemented to indicate out-of-limit
temperature and voltage conditions. The block has an ability to output 20ms low pulse via nRESET pin. The
hardware monitoring block of the LPC47M192 is accessible via the System Management Bus (SMBus).
The LPC47M192 incorporates complete legacy Super I/O functionality including an 8042 based keyboard and mouse
controller, an IEEE 1284, EPP, and ECP compatible parallel port, two serial ports that are 16C550A UART
compatible, two IrDA 1.0 infrared ports, and a floppy disk controller with SMSC's true CMOS 765B core and
enhanced digital data separator, The true CMOS 765B core provides 100% compatibility with IBM PC/XT and PC/AT
architectures and is software and register compatible with SMSC's proprietary 82077AA core. System related
functionality, which offers flexibility to the system designer, includes an MPU-401 MIDI interface, (37) General
Purpose I/O control functions, control of two LED’s, a game port interface supporting two joysticks, and fan control
using fan tachometer inputs and pulse width modulator, (PWM), outputs
The LPC47M192 is ACPI 1.0/2.0 compatible and therefore supports multiple low power-down modes. It incorporates
sophisticated power control circuitry (PCC) which includes support for keyboard and mouse wake-up events.
The LPC47M192 supports the ISA Plug-and-Play Standard register set (Version 1.0a). The I/O Address, DMA
Channel and hardware IRQ of each logical device in the LPC47M192 may be reprogrammed through the internal
configuration registers. There are up to 480 (960 - Parallel Port) I/O address location options, a Serialized IRQ
interface, and Three DMA channels.
The LPC47M192 does not require any external filter components and is therefore easy to use and offers lower
system costs and reduced board area.
