W83627HG Descrizione generale

GENERAL DESCRIPTIONThe W83627HF and W83627F are evolving product fromWinbond's most popular I/O family. Theyfeature a whole new interface, namely LPC（Low Pin Count）interface, which will be supported in the next generation Intel chip-set. This interface as its name suggests is to provide an economical implementation of I/O's interface with lower pin countand still maintains equivalent performance as its ISA interface counterpart. Approximately 40 pin counts are saved in LPC I/O comparing to ISA implementation. With this additional freedom, we can implement more devices on a single chip as demonstrated in W83627F/HF's integration of Game Port and MIDI Port.It is fully transparentin terms of software which means no BIOS or device driver update is needed except chip-specific configuration.MIDI Port The baud rate is 31.25 Kbaud 16-byte input FIFO 16-byte output FIFOGeneral Purpose I/O Ports 22 programmable general purpose I/O ports General purpose I/O ports can serve as simple I/O ports, interrupt steering inputs, watch dogtimer output, power LED output, infrared I/O pins, KBC control I/O pins, suspend LED output,RSMRST# signal, PWROK signal, Beep output Functional in power down mode （GP1 only） OnNow Functions Keyboard Wake-Up by programmable keys Mouse Wake-Up by programmable buttons CIR Wake-Up by programmable keys On Now Wake-Up from all of the ACPI sleeping states （S1-S5）Hardware Monitor Functions （Only for W83627HF） 5 VID input pins for CPU Vcore identification 3 thermal inputs from optionally remote thermistors or 2N3904 transistors or PentiumII（Deschutes）thermal diode output 7 positive voltage inputs （typical for +12V, -12V, +5V, -5V, +3.3V, VcoreA, VcoreB） 2 intrinsic voltage monitoring （typical for Vbat, +5VSB） 3 fan speed monitoring inputs 2 fan speed control Build in Case open detection circuit WATCHDOG comparison of all monitored values Programmable hysteresis and setting points for all monitored items Over temperature indicate output Automatic Power On voltage detection Beep Issue SMI#, IRQ, OVT# to activate system protectionIntel LDCM/ Acer ADMcompatiblePackage 128-pin PQFP
