Overview

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.

Key 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.
