908E624
Functional Description
Introduction
FUNCTIONAL DESCRIPTION
INTRODUCTION
The 908E624 was designed and developed as a highly
integrated and cost-effective solution for automotive and
industrial applications. For automotive body electronics, the
908E624 is well suited to perform relay control in applications
like window lift, sunroof, etc., via a three-wire LIN bus.
The device combines an HC908EY16 MCU core 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
high-side outputs. Other ports are also provided, which
include a current sense operational amplifier port and two
wake-up terminals. An internal voltage regulator provides
power to the MCU chip.
Also included in this device is a LIN physical layer, which
communicates using a single wire. This enables this device
to be compatible with three-wire bus systems, where one wire
is used for communication, one for battery, and one for
ground.
FUNCTIONAL TERMINAL DESCRIPTION
page 1, 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.
The PTB0/AD0 and PTB2/AD2 terminals are 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.
For details refer to the 68HC908EY16 datasheet.
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.
For details refer to the 68HC908EY16 datasheet.
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. 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.
Important
To ensure proper operation, do not add any
external pullup resistor.
For details refer to the 68HC908EY16 datasheet.
MCU POWER SUPPLY TERMINALS (EVDD AND
EVSS)
EVDD and EVSS are the power supply and ground
terminals, respectively. The MCU operates from a single-
power supply.
