AFE4410: How to get datasheet and firmware for AFE4410 and AFE4420?

Part Number: AFE4410
Other Parts Discussed in Thread: AFE4420

Dear Staff,

Recently, my design employed to control four LEDs and AFE4420 or AFE4410 is the most suitable solution. However, when I sent some requests for these wares, some of TI's supporters do not reply to me 

I'm working in a Lab at a University in Korea and I knew these products under NDA polices. So How I can receive datasheets and firmware from your company.
Our Labs had bought a 4900evm board before and also receive the document for this board. So whether or not we must purchase the AFE4420/AFE4410 to get your support?

Hope to receive your support soon.
Thank you!
