SCH4304
In Production
The SCH5017 is a 3.3V Super I/O controller with an LPC interface.
SCH4304 also includes auto fan support, a real time clock, LED
support, two full UARTs, and a multi-mode parallel port. The
SC5017 includes support for monitoring two external temperatures
via thermal diode inputs and an internal sensor for measuring
ambient temperature, and allows for a two or three piece linear fan
function. The SCH4304 incorporates SMBus Backdoor Access to all
registers, and supports up to three T03 sensor devices, and up to
nine sensors, each of which can be assigned to any one or more of
the three auto fan controls. The SMBus Slave Interface has a default
I2C address 5ch for HWM registers and 6ch to RTC registers.
