Hi all, I am going to use a P89LPC9103 in a very small product. We cannot afford to have dedicated pins or jumpers because of size constraints. RST/P1.5, PCL/P0.5 and PDA/P0.4 will have pull-up resistors in hardware, value to be as high a possible. PCL and PDA will have an external small capacitance to drive around 20pF. RST will need to drive 7pF. Vdd will have a reverse biased small signal blocking diode (C=2pF), Vdd for the target board will be 0V. Does anyone know the drive capabilities of ICP for the EPM900? AN10258 recommends full disconnection which is not an option. Thanks Paul.
