General Description

The F82660 is the featured IO chip for Industrial PC system. The F82660 have eSPI and LPC interfaces where the interface would be detected automatically. Those interfaces could be workable with 1.8V or 3.3V.

Equipped with one IEEE 1284 parallel port, 6 UART ports with Multi drop function (9-bit protocol), SIR, ACPI management function. F82660 has 6 UART transceivers, two of which support multi-protocols RS-232/422/485 UART transceivers (UART 1 ~ 2), and the others support pure RS232 UART transceivers (UART 3 ~ 6). Each UART provides 16/32/64/128 bytes FIFO. These UART transceivers can be programmed via a set of I2C interfaces , and the baud rate can support up to 1.5Mbps.

The F82660 supports keyboard and mouse interface which is 8042-based keyboard controller. The F82660 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 F82660 provides flexible features for multi-directional application. For instance, supports 29 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 F82660 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. When the system enters the S3/S4/S5 state, F82660 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, 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 F82660 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. F82660 is in the package of 128 pin-LQFP(14mm x 14mm).
