Advance Information

33742

33742S

System Basis Chip (SBC) with

Enhanced High-Speed CAN

Transceiver

The 33742 and the 33742S are monolithic integrated circuits combining

many functions frequently used by automotive environmental control units

(ECUs).

SYSTEM BASIS CHIP

WITH ENHANCED

HIGH-SPEED CAN

The 33742 is an SBC having a fully protected fixed 5.0 V low-drop regulator

with current limit, overtemperature pre-warning, and reset. An output drive with

sense input is also provided to implement a second 5.0 V regulator, using an

external PNP bipolar junction transistor. The 33742 has normal, standby, stop,

and sleep modes, an internally switched high-side power supply output with

four wake-up inputs, programmable window watchdog, interrupt, reset, SPI

input control, and a high-speed CAN transceiver compatible with CAN 2.0 A

and B protocols for module-to-module communication.
