Hi,
I am designing 8051 trainer board using P89LPC952(from Philips). Can you provide me the "Programming circuitary" required to program the built-in FLASH using ISP(In-System Programming).
Thank You

Dear Erik,
I have gone through MCB900, MCB950 and also the "Loader".
The "NoTouch" ckt you mentioned, are you refering to "Loader" for 921 & 922?
In my view MCB900(Same as MCB950) is easier to rig-up & to use also. As it uses only single IC i.e NOT gate & jumper configuration & by use of RTS & DTR.
If i consider the "Loader" then i have go for 3- diff IC's even though if leave option for 2 - microcontrollers. i.e. h/w cost increases.
What's your view/suggestion?
you can find NoTouch for the C51 and LPC93x at the esacademy website
My submissions (C51 and 'the backdoor') describes the whole thing, the 93x is the code only.
READ IT
To make a version for the 95x should take you a whole 5 minutes after you have read the datasheet.
With NoTouch and, for development, 'the backdoor' in place you need ZERO gates etc because a factory fresh chip arrives in ISP mode.

I have searched in the esacademy.com but unable find the same.
Can you please send me the link?
well, neither can I, wait till they get the website back on line
sorry, theyhave moved it to a new website: www.flashmagictool.com/resources.html
