DALI LPC1114 Slave BOM Detailed Description

Hi,

I'm trying to assembly the DALI Slave LPC1114 and I do need some help with the Bill of Materials (BOM). Does anyone can give a detailed description of the following BOM elements?

Part	Value	Device	Package	Description Remarks
D1	LED0805	LEDCHIPLED_0805	CHIPLED_0805	LED
Q2	12MHz	CRYSTAL4	XTAL4
U$1	FIDUCIAL_0.6	-1.2MM FIDUCIAL_0.6-1.2MM	FIDUCIAL0.6-1.2
U$2	FIDUCIAL_0.6	-1.2MM FIDUCIAL_0.6-1.2MM	FIDUCIAL0.6-1.2
X4		MA14-1W	MA14-1W	PIN HEADER

Can I use any LED and any 12 Mhz Crystal? What FIDUCIAL_0.6 means? Does the PIN Header have some specification?

Regards,

Yuri.

Hi, Yuri,

The D1 is a LED with 0805 package, you can use any LED, which only indicates that the LPC1113 works fine by toggling constantly. The Q2 is a 12MHz crystal with 4 pins, you can use any crystal with 12MHz.

Regarding the FIDUCIAL_0.6 , I do not know. I will ask the other engineers for help.

Hi, Yuri,

Maybe this link is helpful to understand the spec FIDUCIAL, which I get from Google.
