Advance Information

System Basis Chip (SBC) with

Enhanced High-Speed CAN

Transceiver

33742

33742S

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, overtemperature 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.

SYSTEM BASIS CHIP

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.
