Description
The IT8502 is a highly integrated embedded controller with system functions suitable for mobile system applications. The IT8502 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 and ADC for hardware monitor, PS/2 interface for external keyboard/mouse devices, BRAM 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.
