MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
SYSTEM/APPLICATION INFORMATION
INTRODUCTION
The 908E626 device was designed and developed as a
highly integrated and cost-effective solution for automotive and
industrial applications. For automotive body electronics, the
908E626 is well suited to perform stepper motor control, e.g. for
climate or light-levelling control via a 3-wire LIN bus.
This device combines an standard HC08 MCU core
(68HC908EY16) with flash memory together with a
SMARTMOS
IC chip. The
SMARTMOS
IC chip combines
power and control in one chip. Power switches are provided on
the
SMARTMOS
IC configured as four half-bridge outputs.
Other ports are also provided including a selectable HVDD
terminal. An internal voltage regulator is provided on the
SMARTMOS
IC chip, which provides power to the MCU chip.
Also included in this device is a LIN physical layer, which
communicates using a single wire. This enables the device to
be compatible with 3-wire bus systems, where one wire is used
for communication, one for battery, and the third for ground.
FUNCTIONAL TERMINAL DESCRIPTION
See
Figure 1, 908E626 Simplified Internal Block Diagram
,
page 2, for a graphic representation of the various terminals
referred to in the following paragraphs. Also, see the terminal
diagram on
page 3
for a depiction of the terminal locations on
the package.
Port A I/O Terminals
These terminals are special-function, bidirectional I/O port
terminals that are shared with other functional modules in the
MCU. PTA0:PTA4 are shared with the keyboard interrupt
terminals, KBD0:KBD4.
The PTA5/SPSCK terminal is not accessible in this device
and is internally connected to the SPI clock terminal of the
analog die. The PTA6/
SS
terminal is likewise not accessible.
For details refer to the 68HC908EY16 datasheet.
Port B I/O Terminals
These terminals are special-function, bidirectional I/O port
terminals that are shared with other functional modules in the
MCU. All terminals are shared with the ADC module. The
PTB6:PTB7 terminals are also shared with the Timer B module.
PTB0/AD0 is internally connected to the ADOUT terminal of
the analog die, allowing diagnostic measurements to be
calculated; e.g., current recopy, V
SUP
, etc. The PTB2/AD2
terminal is not accessible in this device.
For details refer to the 68HC908EY16 datasheet.
Port C I/O Terminals
These terminals are special-function, bidirectional I/O port
terminals that are shared with other functional modules in the
MCU. For example, PTC2:PTC4 are shared with the ICG
module.
PTC0/MISO and PTC1/MOSI are not accessible in this
device and are internally connected to the MISO and MOSI SPI
terminals of the analog die.
For details refer to the 68HC908EY16 datasheet.
Port D I/O Terminals
PTD1/TACH1 and PTD0/TACH0/BEMF are special-
function, bidirectional I/O port terminals that can also be
programmed to be timer terminals.
In step motor applications the PTD0 terminal should be
connected to the BEMF output of the analog die in order to
evaluate the BEMF signal with a special BEMF module of the
MCU.
PTD1 terminal is recommended for use as an output terminal
for generating the FGEN signal (PWM signal) if required by the
application.
Port E I/O Terminal
PTE1/RXD and PTE0/TXD are special-function,
bidirectional I/O port terminals that can also be programmed to
be enhanced serial communication.
PTE0/TXD is internally connected to the TXD terminal of the
analog die.
The connection for the receiver must be done
externally.
External Interrupt Terminal (
IRQ
)
The
IRQ
terminal is an asynchronous external interrupt
terminal. This terminal contains an internal pullup resistor that
is always activated, even when the
IRQ
terminal is pulled LOW.
For details refer to the 68HC908EY16 datasheet.
External Reset Terminal (
RST
)
A logic [0] on the
RST
terminal forces the MCU to a known
startup state.
RST
is bidirectional, allowing a reset of the entire
system. It is driven LOW when any internal reset source is
asserted.
This terminal contains an internal pullup resistor that is
always activated, even when the reset terminal is pulled LOW.
For details refer to the 68HC908EY16 datasheet.
