Integrated S12 Based Relay
Driver with LIN
The MM912G634 (48 kB) and MM912H634 (64 kB) are
integrated single package solutions that integrate 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)
MM912_634
48-PIN LQFP, 7.0 mm x 7.0 mm
AE SUFFIX: Exposed Pad Option
AP SUFFIX: Non Exposed Pad Option
