APPLICATION NOTES
The following abstracts are of the application notes that
can be found printed in-full in Philips Semiconductor's
Data Handbook IC20
80C51-based 8-bit microcontrollers
,
ordering code 9397 750 00963.
AN422 - Using the 8XC751 microcontroller as an
I2C-bus master
The 83C751/87C751 combines the benefits of a
high-performance microcontroller with on-board hardware
supporting the I2C-bus interface, and thus allows systems
to be completely software defined. This article shows how
best to connect the microcontroller to an I2C-bus
configuration, describes the 8XC751 I2C hardware and
gives a programming example demonstrating a
bus-master code.
AN425 - Interfacing the PCF8584 I2C-bus controller to
80C51 family microcontrollers
This application note describes how to use the PCF8584
I2C-bus controller with the 80C51 family of
microcontrollers. A typical way of connecting the PCF8584
to an 80C31 is given, and some basic software routines
are described showing how to transmit and receive bytes
in a single master system. There is also an example of how
to use these routines in an application that uses the I2C
circuits on an I2C demonstration board.
AN95068 - C routines for the PCF8584
This application note demonstrates how to write a driver in
C for the Philips PCF8584 I2C-bus controller IC and
includes a set of application interface routines to quickly
implement a complete PC multimaster system application.
The driver supports polled or interrupt driver message
handling, slave message transfers and multimaster
system applications. Furthermore, it is suitable for use in
conjunction with real-time operating systems like OS-9 or
pSOS+.
AN430 - Using the 8XC751/752 in multimaster I2C
applications
This article discusses the most important technical
features of the I2C-bus and describes the special I2C
hardware interface of the 8XC751/752. The author gives
an example of how the microcontroller can be
programmed for a multimaster environment along with
details of the software interface for the communications
routes.
AN433 - I2C slave routines for the 83C751
The 8XC751 microcontroller can be programmed as an
I2C-bus master, slave, or both. This article focuses on its
use as a slave and gives a programming example
demonstrating the communications routes of the 8XC751
as a slave on the I2C-bus. This example complements the
program given in article AN422.
AN434 - Connecting a PC keyboard to the I2C-bus
This application note illustrates the use of the 8XC751
microcontroller to interface a standard PC/AT keyboard to
the I2C bus. The application software example easily fits
within the 2K-bytes code and 64-bytes data memory
provided on the 8XC751.
AN438 - I2C routines for 8XC528
This article presents a set of software routines to drive the
I2C interface in 8XC528-type microcontrollers.
A description of the I2C interface is given along with
examples of how to use these routines in PL/M-51, C and
assembly source code.
AN444 - Using the P82B715 I2C extender on long
cables
The P82B715 I2C buffer was designed to extend the range
of the logical I2C-bus out to 50 m. This application note
describes the results of testing the buffer on several
different types of cables to determine the maximum
operating distance possible. The results are summarized
in a table for easy reference.
ETV/AN89004 - PLM51 I2C software interface IIC51
(version 0.5)
This document is a user manual for the I2C software
module IIC51, and is intended for Intel PLM51 users who
need to control an I2C-bus. There is a general description
on the IIC51 software module, although some basic
knowledge about I2C and Intel PLM51 is assumed.
EIE/AN91007 - I2C driver routines for 8XC751/1
microcontrollers
This report described the I2C drivers that are written for the
8XC751/2 and explains the structure of the software and

how to use the routines. The software is written around a
set of basic routines and a message handler.
The message handles contain no specific 8XC751 code
so, by rewriting a set of basic routines, the software
example can easily be modified for any other bit level I2C
interface.
Programming the I2C interface
This article is taken from Dr. Dobb's
Journal and gives a good overview of I2C-bus basics.
It describes hardware requirements, building a framework
and how to connect to the I2C-bus.
The following application note is printed separately.
The full version can be ordered from Philips
Semiconductors.
AN94078 - P90CL301 I2C driver routines
This application note demonstrates how to write an
I2C-bus driver for the Philips P90CL301 microcontroller
and includes a set of application interface software
routines to quickly implement a complete I2C multimaster
system application.
The driver allows you to link modules to your application
software and includes a head-file into the application
source programs. A programming example on how to use
the driver is also listed in the article.
The driver supports polled or interrupt driven message
handling, slave message transfer and multimaster system
applications. Furthermore, it is suitable for use in
conjunction with real-time operating systems such as
pSOS+.
