<strong>MM9Z1</strong>_<strong>638</strong><br />
<strong>Xtrinsic</strong> <strong>Battery</strong> <strong>Sensor</strong> <strong>with</strong> Multiple Voltage <strong>and</strong><br />
Temperature Sense Inputs, MS<strong>CAN</strong>,<strong>and</strong> <strong>LIN</strong><br />
Overview<br />
The <strong>MM9Z1</strong>_<strong>638</strong> enables precision measurement<br />
of key battery parameters in automotive <strong>and</strong><br />
other applications. The device integrates an S12Z<br />
microcontroller <strong>and</strong> a SMARTMOS analog control<br />
IC into a single package solution. The analog die<br />
combines system basis <strong>and</strong> application specific<br />
functions, including a Local Interconnect Network<br />
(<strong>LIN</strong>) transceiver, <strong>and</strong> a two-channel 16-bit sigma<br />
delta (ΣΔ )analog to digital converter (ADC) for<br />
simultaneous measurement of battery voltage <strong>and</strong><br />
current.<br />
<strong>MM9Z1</strong>_<strong>638</strong> Simplified Application Drawing<br />
An integrated temperature sensor combined <strong>with</strong><br />
battery mounting allows measurement of battery<br />
temperature. Control of the analog die is through<br />
the high performance internal Die-to-Die interface<br />
(D2D), which seamlessly integrates the analog IC<br />
registers into the MCU register map, to provide<br />
faster access than SPI-based systems. The<br />
<strong>MM9Z1</strong>_<strong>638</strong> also includes an internal oscillator,<br />
96 KB or 128 KB of Flash memory, <strong>and</strong> 8.0 KB of<br />
RAM, as well as an ms<strong>CAN</strong> module. Optionally<br />
also multiple external temperature sensors are<br />
supported.<br />
