Advance Information
Document Number: MM912_634D1
Rev. 4.0, 5/2011
Integrated S12 Based Relay
Driver with LIN
The MM912G634 (48 kB) and MM912H634 (64 kB) are
integrated single package solutions 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, 64/48 kByte P-FLASH,
• 6.0 kByte RAM; 4/2 kByte D-FLASH
• 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
• 10 digital MCU GPIOs shared with SPI (PA7…0, PE1…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)
