The KB926D is an embedded controller with LPC interface to connect with host. The
embedded controller contains industrial standard 8051 microprocessor and provides function of i8042 keyboard controller basically. The KB926D is designed with Shared-ROM architecture with SPI flash. The EC firmware and system BIOS will exist in one SPI flash. The embedded controller also features rich interfaces for applications, such as PS/2 interface, Keyboard Matrix, PWM, A/D converter, D/A converter, Fan controller, SMBus controller, GPIO controllers and extension interface for future applications. The chapter 1.2 highlights of all features in the KB926D.
- LPC Low Pin Count Interface
- X-bus Bus Interface (XBI) : Flash Interface
- 8051 Microprocessor
- Internal Keyboard Matrix (IKB)
