Product Summary
The CDP68HC68S1E is a Serial Bus Interface Chip (SBlC) provides a means of interfacing in a Small Area Network configuration, various microcomputers (MCU’s) containing serial ports. Such MCUs include the family of 68HC05 microcontrollers. The SBlC provides a connection from an MCU’s Serial Communication Interface (asynchronous UART type interface) or Serial Perip eral Interface (synchronous) to a medium speed asynchronous two wire differential signal bus designed to minimize electro-magnetic interference. This two wire bus forms the network bus to which all MCU’s are connected (through SBI chips). See Fig-ure 1. Each MCU operates independently and may be added or deleted from the bus with little or no impact on bus operation. Such a bus is ideal for inter-microcomputer communication in hazardous electrical environments such as automobiles, aircraft or industrial control systems.
