Description

The IT8512E is a highly integrated embedded controller with system functions suitable for mobile system applications. The IT8512 directly interfaces to the LPC bus and provides ACPI embedded controller function, keyboard controller (KBC) and matrix scan, external flash interface for system BIOS and EC code, PWM, ADC and SmartAuto Fan control for hardware monitor, PS/2 interface for external keyboard/mouse devices, BRAM, CIR and system wake up functions for system power management. It also supports the external flash ( or EPROM) to be shared by the host and EC side.
