Question

Can the CP2114-B01 be distinguished from CP2114-B02 by the package marking?

Answer

No, CP2114-B01 and -B02 can not be distinguished by package marking. 

 

However, the following three device-specific version numbers can be used to distinguish between CP2114-B01 and CP2114-B02 devices:

 

Name

CP2114-B01

CP2114-B02

API Version

0x05

0x06

Firmware Version

0x07

0x08

Config Version

0x01

0x02

 

There are four ways to obtain the version numbers that can be used to distinguish between CP2114–B01 and CP2114–B02 devices:

 

  1. The CP21xx Customization Utility displays the Firmware Version in the device string (CP2114-B02 shown):

    CP2114_Rev_ID_CP21xx_Customization_Utility.jpg

  2. The HidUart Example application displays the API Version (CP2114-B02 shown):

    CP2114_Rev_ID_HidUart_Example.jpg

  3. The HID-to-UART interface library provides the CP2114_GetVersions function, which returns all three version numbers.  For more information, see AN433: CP2110/4 HID-to-UART API Specification.

  4. If not using the HID-to-UART interface library, the Get Device Version report (ID 0x77) can be used to obtain all three version numbers.  For more information see AN434: CP2110/4 Interface Specification.
