• Manufacturer Part Number: mm912f634
• Description: Mm912f634 - Integrated S12 Based Relay Driver With Lin
• Manufacturer: Freescale Semiconductor, Inc

Functional Description and Application Information
4.26
4.26.1
The MC9S12I32 micro controller implemented in the MM912F634 is the first member of the newly introduced S12S
platform, mainly targeted for Intelligent Distributed Control (IDC) applications. The MC9S12I32 device is designed as counter part
to an analog die, and is not being offered as a standalone MCU.
The MC9S12I32 die contains a HCS12 Central Processing Unit (CPU), offering 32 kB of Flash memory and 2.0 kB of system
SRAM, up to six general purpose I/Os, an on-chip oscillator and clock multiplier, one Serial Peripheral Interface (SPI), an interrupt
module, and debug capabilities via the on-chip debug module (DBG) in combination with the Background Debug Mode (BDM)
interface. The MC9S12I32 die has no external bus interface, and thus no emulation capability as well as no internal voltage
regulator. Additionally there is a die-to-die initiator (D2DI) which represents the communication interface to the companion
(analog) die.
