NC
No Connect
No connection.
2
SCLK
Serial Data Clock
Clock input pin for the Serial Peripheral Interface (SPI).
3
MISO
Master In Slave Out
SPI data sent to the MCU by the 33742. When CS is HIGH, the pin is in the high-
impedance state.
4
MOSI
Master Out Slave In
SPI data received by the 33742.
5
CS
Chip Select
(Active LOW)
The CS input pin is used with the SPI bus to select the 33742. When the CS is asserted
LOW, the 33742 is the selected device of the SPI bus.
6
WDOG
Watchdog Output
(Active LOW)
The WDOG output pin is asserted LOW if the software watchdog is not correctly
triggered.
7
RXD
Receive Data
CAN bus receive data output pin.
8
TXD
Transmit Data
CAN bus transmit data input pin.
9
VDD
Voltage Digital Drain
5.0 V regulator output pin. Supply pin for the MCU.
10
RST
Reset Output
(Active LOW)
This is the device reset output pin whose main function is to reset the MCU. This pin has
an internal pullup current source to VDD.
11
INT
Interrupt Output
(Active LOW)
This output is asserted LOW when an enabled interrupt condition occurs. The output is
a push-pull structure.
17-20
41-44
GND
Ground
These device ground pins are internally connected to the package lead frame to provide
a 33742-to-PCB thermal path.
