System Basis Chip with
Enhanced High Speed CAN
Transceiver
The 33742 and the 33742S are SPI-controlled System Basis Chips
(SBCs), combining many frequently used functions, along with a CAN
2.0-compliant transceiver, used in many automotive electronic control
units (ECUs). The 33742 SBC has a fully protected fixed 5.0 V low
dropout internal regulator, with current limiting, over-temperature pre-
warning, and reset. A second 5.0 V regulator can be implemented using
external pass PNP bipolar junction pass transistor, driven by the SBC’s
external V2 sense input and V2 output drive pins.
The SBC has four main operating modes: Normal, Standby, Stop, and
Sleep mode. Additionally, there is an internally switched high side power
supply output, four wake-up inputs pins, a programmable window
watchdog, interrupt, reset, and a SPI module for communication and
control. The high speed CAN A and B transceiver is available for inter-
module communication.
Features
1.0 Mbps CAN transceiver bus interface with bus diagnostic capability
SPI control at frequencies up to 4.0 Mhz
5.0 V low dropout voltage regulator with current limiting, over-
temperature prewarning, and output monitoring and reset
A second 5.0 V regulator capability using an external series pass
transistor
Normal, Standby, Stop, and Sleep modes of operation with low Sleep
and Stop mode current
A high side switch output driver for controlling external circuitry
