Calibration
B.1 Overview
The MPC5500 family of microcontrollers includes various specialized features to support automotive
calibration. Many of these calibration features are not available to the final application software, and some
MPC5500 devices support calibration signals that are not available in the standard 208, 324, and 416 BGA
packages. Special calibration assembled devices with increased signal bond-out provide full access to all
calibration resources for all MPC5500 variants.
Calibration hardware that uses the calibration assembled devices is detailed in Figure B-1.
Freescale-produced VertiCal bases use the calibration-assembled MPC5500 device mounted on a small
circuit board with a footprint which is compatible with that of the production BGA packaged MPC5500
device. A 156-way VertiCal connector on the top-side of the VertiCal base allows you to attach VertiCal
compliant top-board hardware. Various types of top-board hardware to support calibration and debug are
available from Freescale and commercial companies.
The VertiCal connector standard defines the set of signals used to communicate between the
microcontroller on the VertiCal base board and the attached calibration development tools, called
top-boards. Signal availability or sourcing for the VertiCal connector differs depending on the MPC5500
device used.
