ICP Application Design
I don''t intend to leave jumpers in my design to isolate the pins of the ICP from the application.
What''s the minimum pull up and down load resistors of an application for an ICP design using LCP93x parts?
Are the values the same for whole three pins (PCL, PDA and reset) and does a special care must be taken with the Vdd connection?

RE: ICP Application Design
Hello there,

Have you read the Production Programming document?

Please download the PDS51E beat (4.48) located in the downloads area and review this document.

With PDS900 (I cannot comment of other interfaces) we can drive into 100 Ohms but recommend 470 Ohm minimum. The device pins are hi-z at this time so the concern is your external circuitry.

Vdd does require care and thought but the issues are discussed fully in the document.

Regards,
Graham
