Dear Hurgo,
The Philips/NXP P87LPCxxx series of devices are not supported by the S4 programmer.
As a solution I would recommend the Dataman-40Pro Universal Programmer. The 40Pro supports this device in the 20pin DIP package and several others with suitable package adaptor available.
More details on the 40Pro can be found on our website
here.
All our programmers are available from stock at all times and shipped the same day we receive your payment. They come with a 30 day money back guarantee and the 40Pro comes with a 3 year warranty.
If you have any questions or would like further information, please let me know.
Best regards
Neil Parker
