nRF51422 v2 part number

[Mark Rages]

I see that Digi-Key has two part numbers for the nRF51422-QFAA:

But I don't see any reference to "V2" part number field in the nRF51422-PS document.

What is the exact meaning of "V2"? How is this marked on packaging labels? How is this marked on the chip itself?

Edit:

The document "nWP-021" is only for nRF51822, but I guess the nRF51422 is similar:

So my code is compiled with the v6 SDK, so I need my product assembled with one of the following chips:

• nRF51422-QFAA-FA0
• nRF51422-QFAA-GC0
• nRF51422-QFAA-Gx0

But when my supplier orders parts, they will use the order code, from "nRF51422_PS v3.1.pdf":

This order code doesn't have any field for the build code.

• The field is for the package code ("QF")

• The field is for the variant code ("AA")

• The field is for the container code (probably "R")

The build code is not part of the order code, so how can I specify a certain build?

V2 support ANT/BLE SoftDevice. Before version only support ANT SoftDevice.

Mark, if you are just starting out with a new project, go with the new rev 3 silicon, even better go with the QFAC (256K flash, 32K sram) parts. The extra SRAM makes life so much easier and you get a few bug fixes/enhancements for free.

Hi

I think Digikey included the V2 markings in order to seperate the nRF51422 second revision chips from the nRF51422 first revision. The first nRF51422 had preprogrammed ANT softdevice, while the second revision can be flashed with any Nordic softdevice, ANT, ANT+BLE, or BLE, more info on this thread.

I think nRF51422 V3 (third revision) is only available as engineering release at the moment, it resides on the new nRF51 DK, but I assume it will be available in tray as the production version is released.

Update 4.12.2014 Hopefully you are able to identify and select the correct hardware by looking at the nRF51422 PS v2.0 and this thread. nRF51422 PS v3.1 "Ordering information" chapter contains a little more information than PS v2.0

Update 5.12.2014 If you order your nRF51422 chips with order code nRF51422-QFAA-R-V2 then you will get chips with build code Ex0 (<'H'><'P'><'F'>) where x is 0..9, see table nWP-22 table 1. You will not get build code DAA (<'H'><'P'><'F'>) as the <'P'> is a letter and stands for engineering version and is only made for sample chips and early version development kit/evaluation kits. When you order the chips in tray you will always receive the production version which has a number for <'P'>, e.g. build code E00.

So choosing the right build code with the hardware revision suffix (e.g. "V2"), should give you a definite nRF51 product with a definite build code.

Mark,

Your supplier (even Digikey) can generally tell you what build/date codes are on the parts that you'll actually be getting. And both the build and date code are laser etched onto the package.

[Mark Rages]

So specifying " nRF51422-QFAA-x-V2" should get compatible parts for me. Are there any plans to add the "-V2" suffix to the ordering information section of the product spec?
