IT8502 Controller Chip


The IT8502 is a highly integrated embedded controller with system functions suitable for mobile system applications. The IT8502E 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.

An embedded controller, often referred to simply as an “embedded controller” or “EC,” is a microcontroller or microprocessor-based device that is integrated into a larger system or product to perform specific control, monitoring, or management functions. These controllers are designed to operate as part of the embedded system, providing dedicated and often real-time control over various aspects of the system’s operation. Embedded controllers can be found in a wide range of applications and industries, including consumer electronics, automotive, industrial automation, and more.
