Serial Multiplexed Bus Interface
Description
The CDP68HC6SS1 Serial Bus Interface Chip (SBlC) provides a means of interfacing in a Small Area Network configuration, various microputers (MCU’s) containing serial ports. Such MCU’s include the family of 68HC05 microcontrollers. The SBlC provides a connection from an MCU’s Serial munication Interface (asynchronous UART type interface) or Serial Peripheral Interface (synchronous) to a medium speed asynchronous two wire differential signal bus designed to minimize electromagnetic interference. This two wire bus forms the network bus to which all MCU’s are connected (through SBI chips). See Figure 1. Each MCU operates...
