CDP68HC68S1 Datasheet Serial Multiplexed Bus Interface

Manufacturer: Intersil (now Renesas)

General Description

The CDP68HC6SS1 Serial Bus Interface Chip (SBlC) provides a means of interfacing in a Small Area Network configuration, various microcomputers (MCU’s) containing serial ports.

Such MCU’s include the family of 68HC05 microcontrollers.

The SBlC provides a connection from an MCU’s Serial Communication 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.
