F81867 Datasheet, PDF (10/315 Pages) Feature Integration Technology Inc. – 6 UARTs μSuper IO With 128 Bytes FIFO and Power Saving Functions

F81867
1. General Description
The F81867 is the featured IO chip with μC based on 8-bit 8032 core & built in 8k*8
flash targeted for Industrial PC system. Equipped with one IEEE 1284 parallel port, 6 UART
ports with Multi drop function (9-bit protocol), KBC, SIR, ACPI management function,
portable CIR with RC6 and one FDC. Each UART provides 16/32/64/128 bytes FIFO. The
UART supports legacy speeds up to 115.2K bps as well as even higher baud rates of 230K,
460K, or 921K bps to support higher speed modems. The F81867 supports the enhanced
parallel port (EPP) and the extended capabilities port (ECP). The F81867 supports
keyboard and mouse interface which is 8042-based keyboard controller. The F81867
integrated with hardware monitor, 7 sets of voltage sensor, 3 sets of creative auto-controlling
smart fans and 2 temperature sensor pins for the accurate dual current type temperature
measurement for CPU thermal diode or external transistors 2N3906 and one local
temperature.
The F81867 provides flexible features for multi-directional application. For instance,
supports 72 GPIO pins, IRQ sharing function designed in UART feature for particular usage
and accurate current mode H/W monitor will be worth in measurement of temperature.
Others, the F81867 supports newest Intel PECI 3.0 interfaces for new generational CPU
temperature usage, INTEL IBX PEAK, I2C and AMD TSI for temperature reading.
In order to save the current consumption when the system is in the soft off state which
is so called power saving function. The power saving function supports the system boot-on
not only by pressing the power button but also by the wake-up events via GPIO0x, GPIO1x,
RI1#, and RI2#. When the system enters the S3/S4/S5 state, F81867 can cut off the VSB
power rail which supplies power source to the devices like the LAN chip, the chipset, the
SIO, the audio codec, DRAM, and etc. The PC system can be emulated to G3-like state
when the system enters S3/S4/S5 states. At the G3-like state, the F81867 consumes 5VSB
power rail only. The integrated two control pins are utilized to turn on or off VSB power rail in
the G3-like status. The turned on VSB rail is supplied to a wake up device to fulfill a low
power consumption system which supports a wake up function.
These features as above description will help you more and improve the product value.
The F81867 is in the package of 128-LQFP. (14mm*14mm)
