CDP68HC68S1

Serial Multiplexed Bus Interface

April 1994

Features

Description

• Differential Bus for Minimal EMl

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 Periph-

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.

• High Common Mode Noise Rejection

•

Ideal for Twisted Pair Wiring

• Data Collision Detection

• Bus Arbitration

• Idle Detection

• Programmable Clock Divider

• Power-On Reset

Ordering Information

In addition to acting as bus arbitor and interface for microcom-

puter SCI port to differential bus communication, the

CDP68HC68S1 contains all the circuitry required to convert

and synchronize Non-Return-to-Zero (NRZ) 8-bit data received

on the differential bus and clock the data into a microcomputer’s

SPl port. Likewise, data to be sent by a microcomputer’s SPI

Refer to the data sheet for the CDP68HCO5C4 for additional

information regarding CDP68HCO5 microcomputers and their

Serial Communications and Serial Peripheral Interfaces.

The CDP68HC68S1 is supplied in a 14 lead dual-in-line plastic

package (E sufﬁx), and in a 20 lead small outline plastic pack-

age (M sufﬁx).

Operating voltage ranges from 4V to 7V and operating temper-

ature ranges from -40^oC to +105^oC.
