Hi,
As the following screenshot, the LPC4370 was released in 2013, the longevity is 15 year, it will be expired at 2028.

The LPC4370 has unique feature, it's ADC can reach up to to 80MSPS with 12 bit resolution.
As the following link, I suppose that it said that the "LPC-LINK2 board" is not recommended in new design, if you want to get stand-alone debug probe, you can select MCU-LINK or MCU-LINK Pro.
If you want to test the high speed ADC feature of LPC4370, you can order two LPC-LINK2 boards, one function as target board to test the ADC function, one functions as stand-alone debug probe to debug the target board.
Hope it can help you
