MM912G634DV2AP

Application Specific Microcontrollers Overview

The MM912G634DV2AP is a 16-bit microcontroller integrating an HCS12 CPU with a SMARTMOS analog control IC in a single package. It features 48 kB P-FLASH, 6 kB RAM, and 2 kB D-FLASH, operating at a maximum bus frequency of 16 MHz within the -40°C to 105°C temperature range. The device utilizes Analog Option A2, which includes a battery sense module but excludes the current sense module. Key hardware components include two high-side outputs, four wake-up capable high-voltage inputs (L0–L3), a LIN 2.1 physical layer interface, and a 10-bit ADC.

Application Specific Microcontrollers Feature Summary

• Integrated HCS12 MCU with SMARTMOS analog die via Die-to-Die interface
• Analog Option A2: Battery sense enabled; Current sense disabled
• LIN 2.1 Physical Layer Interface with integrated SCI
• Two protected high-side outputs and two low-side outputs for inductive loads

Application Specific Microcontrollers Applications

• Automotive relay driver systems
• LIN-based automotive network nodes
• Inductive load switching applications

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and analog feature availability. Confirm that the required analog functions, such as the absence of current sensing, align with the design specifications before procurement.

Application Specific Microcontrollers Selection Notes

Select this variant over other MM912_634 derivatives if the application requires Analog Option A2, specifically utilizing the battery sense module while omitting the current sense module. Ensure the 16 MHz bus frequency meets the processing requirements and that the LQFP48 package fits the board layout constraints.

Application Specific Microcontrollers Part Context

This component belongs to the MM912_634 family, which combines S12 microcontrollers with SMARTMOS technology. The 'G' designation indicates 48 kB Flash memory, distinguishing it from the 'H' variant with 64 kB. The 'DV2AP' suffix specifies the 105°C industrial temperature grade, LQFP48 package, and Analog Option A2 configuration.

Application Specific Microcontrollers Replacement Considerations

MM912G634DV1AE offers similar functionality with a different temperature range (-40°C to 125°C) and potentially different analog options. Verify the specific analog feature set (A1 vs A2) and temperature rating when considering substitutes.
