MM912I637AM2EPR2

Application Specific Microcontrollers Overview

The MM912I637AM2EPR2 is a fully integrated LIN battery monitoring device based on NXP SMARTMOS and S12 MCU technology. It features an embedded S12 microcontroller with 96 kB flash, 6.0 kB RAM, and 4.0 kB data flash. The device supports precise current measurement via an external shunt resistor and voltage measurement directly at the battery plus pole. It includes an integrated temperature sensor and a LIN 2.1 interface for bus communication. Operating conditions range from -40 °C to +125 °C, with a maximum input voltage of 42 V.

Application Specific Microcontrollers Feature Summary

Integrated S12 microcontroller with 96 kB flash and 6.0 kB RAM
Precision current measurement in up to 8 ranges using an external shunt
Battery voltage measurement via series resistor at the positive pole
LIN 2.1 interface for sensor feedback availability on the LIN Bus

Application Specific Microcontrollers Applications

12 V Lead-acid battery monitoring

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized channels as counterfeit risks exist. Confirm the specific analog option (Option 2) matches design requirements, noting that Option 2 includes fully characterized cranking mode and external wake-up capabilities. Ensure the QFN-48 package dimensions align with PCB layout constraints before finalizing procurement.

Application Specific Microcontrollers Selection Notes

Select this variant over the MM912J637 if 96 kB flash memory suffices for the application firmware. Verify that the required analog features, such as external wake-up and optional voltage sense inputs, are supported by the specific analog option code within the AM2 suffix. Ensure the system design accommodates the 48-pin QFN thermal enhanced package requirements.

Application Specific Microcontrollers Part Context

This part belongs to the MM912_637 family of intelligent integrated precision battery sensors. It utilizes the M97W analog mask and corresponds to silicon revision 2.4. The device integrates both the analog front-end and the digital control logic into a single SmartMOS solution designed for automotive environments.
