Overview
Freescale Semiconductor, Inc.
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33742 Rev 2.
0, 10/2004 Advance Information 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).
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.
Features • High-Speed 1.
0 Mbps CAN Interface with Bus Diagnostic Capability (Detection of CANH and CANL Short to Ground, to VDD, and to VSUP) • Low-Drop Voltage 5.
0 V, 200 mA VDD Regulator with Current-Limiting, Overtemperature Pre-Warning, and Output Monitoring with Reset • Additional 5.
0 V Regulator with External Series Pass Transistor • Normal, Standby, Stop, and Sleep Modes with Low Sleep and Stop Mode Current • 150 mA High-Side Switch Output for Control of External Circuitry • Four External Wake-Up Inputs • Software-Programmable Watchdog Window, Interrupt, and Reset 33742 33742S SYSTEM BASIS CHIP WITH ENHANCED HIGH-SPEED CAN Freescale Semiconductor, Inc.
