I need help about 68HC705C8

Gabriel_Markez — Sat, 07 Jul 2007 10:06:07 GMT

I need read EPROM/OTPROM (PROM) in order to program other 68HC705C8.

How can I do it ?... Can I Build a Reader/Programmer for the 68HC705C8 MicroController? would you recommend what software to use?...

Hi Gabriel,

You can read all about this, along with programmer circuits in the devices data sheet.

MC68HC705C8A.pdf

which can be found here:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?ProdMetaId=ProdMetaId%2FDocumentation%2F68HC705C8A&isAdvanceSearch=false&showCustomCollateral=false&RELEVANCE=true&showAllCategories=false&fpsp=1&fromPSP=true&SelectedAsset=Documentation&pageNum=4&assetLocked=false&leftNavCode=1&assetLockedForNavigation=true&sortSpec=Type&isAsc=true&code=68HC705C8A&componentId=2&fromWebPages=false&tab=Documentation_Tab&pageSize=25&isComparison=false&

However if the security has been set, none of this will help you read the contents of the PROM.
