Overview: Freescale Semiconductor Technical Data Document Number: MC33889 Rev. 12.0, 3/2007 System Basis Chip with Low Speed Fault Tolerant CAN Interface
An SBC device is a monolithic IC bining many functions repeatedly found in standard microcontroller-based systems, e.g., protection, diagnostics, munication, power, etc. The 33889 is an SBC having fully protected, fixed 5.0 V low drop-out regulator, with current limit, over-temperature 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. The 33889 has Normal, Standby, Stop and Sleep modes; an internally switched high-side power supply output with two wake-up inputs; programmable timeout or window watchdog, Interrupt, Reset, SPI input control, and a lowspeed fault tolerant CAN transceiver, patible with CAN 2.0 A and B protocols for module-to-module munications. The bination is an economical solution for power management, high-speed munication, and control in MCU-based systems.
