3 / 228 page  SMSC DS – LPC47M192 Page 3 Rev. 03/30/05 DATASHEET 1 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.
