Akom AK2001
1 Introduction
1.1 General Description
The AK2001 functions as a debug port on the motherboard. It features a new LPC host interface,
built-in BCD to 7-segment decoders, time-multiplexed LED drivers and scanning control. With a
minimal pin count of 20 in SSOP package, the AK2001 provides all the circuitry required to
interface a motherboard to two hexadecimal digit seven-segment LEDs.
The AK2001’s debug port function allows real time display of POST codes during system boot.
The LED display is able to reflect the system health status so as to provide the cue about what
really happened in case of the system failure, which makes the task of firmware debugging and
hardware troubleshooting much easier. For both end users and technical support staff, the debug
port function proves to be a valuable companion to motherboard and the AK2001 provides an
easy-to-implement, cost-effective, and PCB space saving solution.
