Hi,
Are there anyone here still using this chip. I googled for its programmer and the details for making one was deleted from the site due to no demand.
The chip was made by Motorola and second-sourced by ST Micro and we have plenty of them used in the line interface cards in an Ericsson AXE type exchange as well as in some Home Alarm systems.
Where can I get the programmer to read the contents of its eprom or is there an easy circuit I can construct to read the memory contents?
Is it possible to use its CPU core and connect external RAM and ROM like the 8051 does?
Thanks in advance.
Allen
