8 Hardware Revision History

8.1 Hardware Revision History and Known Issues

This user guide provides information about the latest available revision of the board. The following sections contain information about known issues, a revision history of older revisions, and how older revisions differ from the latest revision.

8.1.1 Identifying Product ID and Revision

There are two ways to find the revision and product identifier of the MTCH9010 Evaluation Kit:
  1. Check the sticker on the bottom of the PCB.
  2. Read the information from the on-board USB bridge. This method requires familiarity with USB devices or a dedicated application to read USB device information.
The accompanying sensor boards’ revision and product identifier can be found on the sticker labels on the bottom of the sensor PCBs.

The first nine digits of the serial number contain the product identifier and revision. The data matrix code on the sticker contains a string with the product identifier, revision and serial number.

The product identifier and revision are printed in plain text on the MTCH9010 Evaluation Kit as 02-01228/rr and on the sensor boards as 02-01348/rr, where “rr” represents the revision. The serial number is printed on the following line.

The string in the data matrix code has the following format:

"nnnnnnnrrsssssssss"

n = product identifier

r = revision

s = serial number

8.1.2 Revision 5

Revision 5 is the initially released board revision.

Known issue: The slew rate limiting for the U208 - MIC2008 is implemented incorrectly. The capacitor on the CSLEW pin is currently connected to GND, which causes the slew rate for VCC_P5V0 to be approximately 50 V/ms. For the correct implementation, the capacitor is instead connected between the VIN and CSLEW pins to achieve the intended slew rate limiting.
