KIT912F634EVME Introduction
Freescale Semiconductor’s KIT912F634EVME is a system solution which gives the user the capability to easily
evaluate most of the features provided by the MM912F634 - integrated dual low-side and dual high-side switch
with embedded MCU and LIN transceiver for relay drivers. The MM912F634 features two dice in a single
package. The 16-bit core and the analog die are connected by means of the Die-to-Die interface that provides
direct address access to the registers on the analog die. The analog die contains HS and LS switches, as well
as a PWM module, ADC module, 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 can be powered either from two 4.0 mm banana connectors or from the
LIN connector. For quick familiarization with the device, a graphical user interface, based on FreeMASTER
software, is provided together with the module. Thanks to the GUI, the user can easily evaluate the peripheral
modules, or directly access the registers on the analog die.

Caution
1. When working with the kit, always use an isolated laboratory power supply.
2. 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 EDS events can destroy or damage the device, or cause its malfunction.
