Hi
I've been trying to program an AT89S52 PLC44 flash chip (8052) using an IceTech Micromaster LV48 programmer and it won't accept the signature of the device. It gives an error message suggesting several possibilities
- including "Secure".
I can read an OTP device ok and its signature is ok. We use a PLCC to DIP adapter from micromaster - AD-44PL-44DIP.
Anyone had problems with the Atmel AT89S52?
