F71858
1. General Description
The F71858 is hardware KBC integrating the ACPI, temperature sensing and fan control
functions specific for the legacy free MB application.
systems.
The KBC functions include one keyboard and
one PS/2 mouse, and can be used with IBM
®-
compatible personal computers or PS/2-based
The controller receives serial data from the keyboard or PS/2 mouse, checks the parity of
the data, and presents the data to the system as a byte of data in its output buffer. The controller will
assert an interrupt to the system when data are placed in its output buffer.
The F71858 provides the ACPI control signals as well such as S3 state, resume reset, PCI reset
outputs or power OK signals.
The power LED is programmable and compliant with PC2001.
One HW_IRQ (alert signal) will be
4 fan monitoring inputs and 3 fan
As to the environment sensing functions, F71858 provides 2 remote analog dual current temp.

issued while the temperature is over the programmable limit.
controlling outputs provide Fintek’s patented auto-fan controlling features. Besides, the F71858
supports AMDSI and Intel PECI/SST interfaces for next generation CPU temp. sensing technology.
F71858 is in LPC interface and powered by 3VCC, 3V standby, and battery.
