MM912G634DM1AE

Application Specific Microcontrollers Overview

The MM912G634DM1AE is an integrated single-package solution combining an HCS12 microcontroller with a SMARTMOS analog control IC. It features a 16-bit S12 CPU operating at a maximum bus frequency of 20 MHz, equipped with 48 kB P-FLASH, 2 kB D-FLASH, and 2 kB RAM. The device includes a LIN 2.1 physical layer interface, a 10-bit 15-channel ADC, and six high-voltage wake-up inputs. It provides two protected low-side outputs for inductive loads and two protected high-side outputs. The component operates within a temperature range of -40°C to 125°C and is housed in a 48-pin LQFP-EP package.

Application Specific Microcontrollers Procurement Notes

Verify the specific analog option A1 configuration, which includes battery sense and current sense modules. Confirm the package variant AE corresponds to the 48-pin LQFP-EP with exposed pad. Ensure the ordering suffix matches the required temperature range and pinout specifications for the target design.

Application Specific Microcontrollers Selection Notes

Select this model when 48 kB program memory is sufficient and the extended temperature range up to 125°C is required. The A1 analog option provides necessary features like current sensing and multiple high-voltage inputs. Compare against the MM912H634 series if higher memory capacity or different analog options are needed.

Application Specific Microcontrollers Part Context

This part belongs to the MM912_634 family, which integrates S12-based microcontrollers with SMARTMOS technology. The 'G' designation indicates 48 kB Flash memory, while 'H' denotes 64 kB. The 'D' suffix specifies the industrial/automotive temperature range, and 'M1' identifies the specific analog option and package type.
