MCB900: 89LPC932 Chip Revisions

Information in this article applies to:

• MCB900 Evaluation Boards

QUESTION

How can I determine the step of the 89LPC932 device on my MCB900 board?

ANSWER

The 89LPC932 device is marked in one of two ways: either with a sticker displaying ISP K1.0 or similar, or with numbers and letters printed onto the device casing.

• If your device has the ISP K1.0 or similar sticker, then it is a special version of the 89LPC932 with a different ISP entry method to the standard devices. The chips marked with ISP K1.0 are special versions of the 89LPC932, which were produced to make samples of the device available quickly. They are based on the revision C device and have the same errata sheet, if any. These chips do not have the same ISP entry method as the standard 89LPC932. Therefore, the relevant sections of the 89LPC932 datasheet do not apply.

• If your device has numbers and letters printed onto it, then you have a standard 89LPC932. You must determine the revision number of your device to find out its capabilities. The printed numbers and letters roughly take on the following form:

  P89LPC932x x
  xxxxxxx xx
  xxYYWW R
  

  The R letter at the end of the third line shows the revision number. It will be B, C, E, F or some letter after F.
