Freescale Semiconductor Advance Information Document Number: MM912_P812 Rev. 1.0, 05/2012 S12P MCU and Multifunctional Ignition and Injector Driver 912_P812 System In Package (SiP) The MM912xP812 is an engine control IC combining an MCU (S12P) and analog control die (MC33812) intended for motorcycle and other single/dual cylinders small engine control applications. The MCU S12P has 6 KB RAM, and flash memory size of 96 KB or 128 KB. The S12P family uses many of the same features found on the S12XS family, including error correction code (ECC) on flash memory, a separate data-flash module for diagnostic or data storage, a fast analog-to-digital converter (ATD), and a frequency modulated phase locked loop (IPLL) that improves the electromagnetic compatibility (EMC) performance. The analog control IC consists of three integrated low side drivers, one pre-driver, a +5.0 V, voltage pre-regulator, an MCU watchdog circuit, an ISO 9141 K-Line interface, and a parallel interface for MCU communication. The three low side drivers are provided for driving a fuel injector, a lamp or LED, and a relay or another injector or fuel pump. The pre-driver is intended to drive either an insulated gate bipolar transistor (IGBT) or a bipolar Darlington transistor to control an ignition coil.
