p89LPC952 programming circuit

Rajkiran Dundaraddi

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

    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.
