nRF51822 revision

How do I identify the hardware revision of my nRF51822 chip?

[Stefan Birnir Sverrisson]

To identify what nRF51822 chip you have, read the "How to identify the harware revision" in nWP-021.

The hardware revision of nRF51822 can be determined by looking at table 1 in the nWP-021 white paper.

• The chips that have Product Specification document v1.x in table 1 are first revision nRF51822 hardware
• The chips that have Product Specification document v2.x in table 1 are second revision nRF51822 hardware
• The chips that have Product Specification document v3.x in table 1 are third revision nRF51822 hardware

Update 28.1.2015 A more obvious way to see the hardware revision of any nrf51 chip is to look at the nRF51 compatibility matrix

Update 8.5.2015 To see the hardware revision, RAM size and ROM size progrmmatically, call the nrf_ic_info_get function defined in \nRF51_SDK_8.1.0_b6ed55f\components\libraries\ic_info\nrf_ic_info.h. This function is new for nRF51 SDK 8.1.0, it is not present in SDK 8.0.0

The 'T' and the 'R7' describe the packaging of the chip. On page 74 in the product specification (available here) you can read that the 'T' means tray and 'R7' means 7''Reel.
