The memory module for the SLC 5/03, SLC 5/04, and SLC 5/05
processors is called Flash EPROM (Flash Erasable Programmable
Read Only Memory). Flash EPROMs combine the programming
versatility of EEPROMs with the security precautions of UVPROMs.
This means that you have the option of leaving your EPROM
programs write protected or unprotected. Write protect the EPROM
using either your software or a PROM programmer.
The memory modules consist of a Flash EPROM mounted on a
circuit board with a connector and plastic housing. There are 2
memory modules available that backup up to 32K or 64K user
memory.
See the table below for details on the Flash EPROM and adapter
socket.
Adapter sockets are required when inserting memory modules into
commercially available PROM programmer. The memory module
fits into the adapter socket and then into a PROM programmer.
!
ATTENTION: Make sure the adapter is inserted
properly or damage could result.
