Rev. 5.0, 11/2010
Integrated S12 Based Relay
Driver with LIN
The MM912F634 is an integrated single package solution that
integrates an HCS12 microcontroller with a SMARTMOS
analog control IC. The Die to Die Interface (D2D) controlled
analog die combines system base chip and application specific
functions, including a LIN transceiver.
Features
• 16-Bit S12 CPU, 32 kByte FLASH, 2.0 kByte RAM
• Background Debug (BDM) & Debug Module (DBG)
• Die to Die bus interface for transparent memory mapping
• On-chip oscillator & two independent watchdogs
• LIN 2.1 Physical Layer Interface with integrated SCI
•wwSwix.DdaitgaSithaeletM4UC.nUetGPIOs shared with SPI (PA5…0)
• 10-Bit, 15 Channel - Analog to Digital Converter (ADC)
• 16-Bit, 4 Channel - Timer Module (TIM16B4C)
• 8-Bit, 2 Channel - Pulse width modulation module (PWM)
• Six high voltage / Wake-up inputs (L5.0)
• Three low voltage GPIOs (PB2.0)

3 Electrical Characteristics
3.1 General
This supplement contains electrical information for the embedded MC9S12I32 microcontroller die, as well as the MM912F634
analog die.
3.2 Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only. A functional operation under or outside those maxima is not guaranteed.
Stress beyond those limits may affect the reliability or cause permanent damage of the device.
This device contains circuitry protecting against damage due to high static voltage or electrical fields. However, it is advised that
normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this high-impedance
circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. All voltages are with respect
to ground unless otherwise noted.
