FUNCTIONAL DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
SPI INTERFACE & PWM CONTROL
The SPI and PWM interfaces are mastered by the core IC
(CPU), and are used to control the output functions of the
Analog IC, as well as to report status and failure information
of the Analog IC.
LIN INTERFACE
The LIN interface function supports the single wire bus
transmit and receive capabilities. It is suited for automotive
bus systems and is based on the LIN bus/physical layer
specification. The LIN driver is a low side MOSFET with slope
control, internal current limitation, and thermal shutdown.
ANALOG MULTIPLEXER
To be able to have different sources for the MCU with one
single signal, an analog multiplexer is integrated in the analog
IC. This multiplexer has eleven different sources on the
Analog IC, which can be selected with the SS[3:0] bits
(through SPI communication) in the A0MUCTL register.
ANALOG INPUT W/INTEGRATED CURRENT
SOURCE
The terminal A0 provides a switchable current source, to
allow the reading of switches, NTC, etc., without the need for
an additional supply line for the sensor (single wire). There
are four different selectable current source values.
OUTPUTS:
HIGH SIDE DRIVERS & DIAGNOSTICS
The HS outputs are low RDS(ON) high side switches.
Each HS switch is protected against over-temperature and
over-current. The output is capable of limiting the inrush
current with an automatic PWM, or feature a real PWM
capability using the PWM input.
H-BRIDGE DRIVERS & DIAGNOSTICS
The device includes power MOSFETs configured as four
half-bridge driver outputs. These outputs are short-circuit and
over-temperature protected. Over-current protection is done
on both high side and low side MOSFETs.
MM68HC908EY16 CORE IC
M68HC08 CPU W/ALU, RAM, FLASH ROM
This possesses the functionality of the CPU08
architecture, along with 512 bytes of RAM and 15,872 bytes
of FLASH memory, with in-circuit programming.
POWER MODULE W/P0WER-ON-RESET
This block of circuitry manages the power supplied to the
core IC, as well as providing POR, LVI, Watchdog timer, and
MCU supervision circuitry (COP).
INTERNAL CLOCK MODULE
This module provides the clocks needed by the core IC
functions, without the need for external components.
Software selectable bus frequencies are available. It also
provides a clock monitor function.
10-BIT ADC MODULE
This module provides an 8-channel, 10-bit successive
approximation analog-to-digital converter (ADC).
I/O PORTS A, B, C, D, E
There are many I/O pins that are controlled by the CPU
through the several I/O ports of the core IC.
TIMER MODULES
There are two 16-bit, 2 channel timer interface modules
with selectable input capture, output compare, and PWM
capabilities, for each channel.
COMMUNICATION MODULES
There are several communication functions supported by
the core IC, including an enhanced serial communication
interface module (ESCI) for the LIN communication, and an
SPI module for inter-IC communication.
RESET & IRQ
There are interrupt and reset connections between the
Analog IC and the core IC, for concise control and error/
exception management.
