S12XS MCU and Multifunctional Ignition and Injector Driver System In Package (SiP)
The MM912_S812 is an engine control SMARTMOS IC combining an MCU (S12XS) and analog control die (MC33812) intended for motorcycle and other single cylinder small engine control applications.The MCU S12XS has 8.0 KB or 12 KB RAM, and flash memory size of 128 KB or 256 KB. The S12XS family retains many of the features of the S12XE family including error correction code (ECC) on flash memory, a separate data-flash module for code or data storage, a frequency modulated locked loop (IPLL) that improves the EMC performance and a fast ATD converter.
Features:
Designed to operate over the range of ~4.7 V ≤ VPWR ≤ 36 V Relay/injector/fuel pump driver – current limit – 4.0 A, typical Lamp driver – current limit – 1.5 A, typical All external outputs protected against short to battery and overcurrent VCC voltage pre-
regulator provides +5.0 V power for the MCU MCU watchdog timer circuit with parallel refresh/time setting line ISO-9141 K-Line transceiver for communicating diagnostic messages
