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.
SMALL ENGINE CONTROL SIP 98ASA00371D 100 Pin LQFP-EP 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 over-current • 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 • All signal lines are accessible • Also available with MC9S12XEP100 MCU for calibration • For detailed specifications see data sheets for the MC33812 and MC9S12Pxxx • Provides single packag...
