General Description

The F81866A is the featured IO chip for Industrial PC system. Equipped with one IEEE 1284 parallel port, 6 UART ports with Multi drop function (9-bit protocol), SIR, ACPI management function and 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 F81866A supports the enhanced parallel port (EPP) and the extended capabilities port (ECP). The F81866A supports keyboard and mouse interface which is 8042-based keyboard controller. The F81866A 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 F81866A 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 F81866A 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, F81866A 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 F81866A 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 F81866A is in the package of 128-LQFP. (14mm*14mm)

When you plug the device into your USB, Windows will look for the associated driver, if it cannot find this driver then you will be prompted to insert the driver disc that came with your device. Common USB Device errors are ‘ usb port not working ‘, ‘device descriptor request failed error’ or ‘bugcodeusbdriver’ issues.
