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 pins. 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 PIN DESCRIPTION
page 1, for a graphic representation of the various pins
referred to in the following paragraphs. Also, see the pin
diagram on page 3 for a depiction of the pin locations on the
package.
PORT A I/O PINS (PTA0:4)
These pins are special function, bidirectional I/O port pins
that are shared with other functional modules in the MCU.
PTA0:PTA4 are shared with the keyboard interrupt pins
KBD0:KBD4.
The PTA5/SPSCK pin is not accessible in this device and
is internally connected to the SPI clock pin of the analog die.
The PTA6/SS pin is likewise not accessible.
For details, refer to the 68HC908EY16 data sheet.
PORT B I/O PINS (PTB1:7)
These pins are special function, bidirectional I/O port pins
that are shared with other functional modules in the MCU. All
pins are shared with the ADC module. The PTB6:PTB7 pins
are also shared with the Timer B module.
The PTB0/AD0 and PTB2/AD2 pins are not accessible in
this device.
For details, refer to the 68HC908EY16 data sheet.
PORT C I/O PINS (PTC2:4)
These pins are special function, bidirectional I/O port pins
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 pins of the analog die.
For details, refer to the 68HC908EY16 data sheet.
PORT D I/O PINS (PTD:0:1)
PTD1/TACH1 and PTD0/TACH0/BEMF are special
function, bidirectional I/O port pins that can also be
programmed to be timer pins.
For details, refer to the 68HC908EY16 data sheet.
PORT E I/O PIN (PTE1)
PTE1/RXD and PTE0/TXD are special function,
bidirectional I/O port pins that can also be programmed to be
enhanced serial communication.
PTE0/TXD is internally connected to the TXD pin of the
analog die. The connection for the receiver must be done
externally.
For details, refer to the 68HC908EY16 data sheet.
EXTERNAL INTERRUPT PIN (IRQ)
The IRQ pin is an asynchronous external interrupt pin. This
pin contains an internal pull-up resistor that is always
activated, even when the IRQ pin is pulled LOW.
For details, refer to the 68HC908EY16 data sheet.
EXTERNAL RESET PIN (RST)
A logic [0] on the RST pin forces the MCU to a known
startup state. It is driven LOW when any internal reset source
is asserted.
This pin contains an internal pull-up resistor that is always
activated, even when the reset pin is pulled LOW.
Important
To ensure proper operation, do not add any
external pull-up resistor.
For details, refer to the 68HC908EY16 data sheet.
MCU POWER SUPPLY PINS (EVDD AND EVSS)
EVDD and EVSS are the power supply and ground pins,
respectively. The MCU operates from a single power supply.
Fast signal transitions on MCU pins place high, short
duration current demands on the power supply. To prevent
noise problems, take special care to provide power supply
bypassing at the MCU.
For details, refer to the 68HC908EY16 data sheet.
