i hav some problem relate to the MON51, 
my microcontroller is at89s8252 
i using the max232, and rs232 serial port 
and a eeprom for MON51 program. 

 
atmel AT89S8252 got internal ram 256 byte 
i wan ask that the MON51 require 256 bytes von Neumann</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: c51 mon51 problem at89s8252</title><link>https://community.arm.com/thread/146295?ContentTypeID=1</link><pubDate>Wed, 03 Dec 2008 23:55:26 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:319d10f0-5c45-4852-b678-cba5c47591b2</guid><dc:creator>k ky</dc:creator><description>&lt;p&gt;&lt;p&gt;
too many question....&lt;br /&gt;
better get msn, becos i scare my hardware connection got
problem....&lt;br /&gt;
msn can send file..., or the circuit diagram...&lt;/p&gt;

&lt;p&gt;
can ask? ...&lt;br /&gt;
for mon51...it must have:&lt;br /&gt;
1 external ram (store program)&lt;br /&gt;
1 eeprom (for mon51 program)&lt;br /&gt;
1 microcontroller&lt;br /&gt;
1 latch&lt;br /&gt;
max232 and rs232 ...&lt;/p&gt;

&lt;p&gt;
am i correct?&lt;/p&gt;

How can other people benefit from your solution, if it is done via
mail or chat? be social and share...&lt;/p&gt;

To use MON51, you must meet the requirements stated in the
&lt;b&gt;documentation&lt;/b&gt; - which includes Von Neumann memory.&lt;/p&gt;

&lt;p&gt;
Perhaps you should be looking at ISD51 instead:&lt;/p&gt;
