Freescale Semiconductor’s KIT912J637EVME is a system solution that gives the user the capability to easily
evaluate most of the features provided by the MM912J637 - Xtrinsic Battery Sensor. The 912J637 features two
die in a single package. The 16-bit core and the analog die are connected via the die to die interface that
provides direct address access to the registers on the analog die. The analog die contains three 16-bit sigma
delta converters and enables simultaneous sampling of battery voltage and current, timer module, SCI module,
LIN physical interface, and other general registers. All external signals are accessible via header connectors,
and most of the signals can also be checked via test points. The evaluation module board also includes the
TBDML programming/debugging interface, so no external interface is needed. The board is powered from two
4.0 mm banana connectors. For quick familiarization with the device, a CodeWarrior Template is provided
together with the EVB.
When working with the kit, always use an isolated laboratory power supply.
Keep in mind all ESD rules when handling the board. Avoid touching the connector pins. They are directly
connected to the device pins. Even though the device pins are ESD protected, this protection has its limits.
Some ESD events can destroy or damage the device, or cause its malfunction.
