 DESCRIPTION

Memory Backup for the 1747-L511, SLC 5/01 Processor 

The curve below illustrates the ability of the memory back-up capacitor to maintain the contents of the RAM in a 1747-L511 processor. To back up the memory for a longer period of time, a lithium battery, catalog number 1747-BA, is required.

Selecting a Memory Module for SLC 5/03, SLC 5/04, and SLC 5/05 Processors

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 by 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. Adapter sockets (catalog number 1747-M15) are required when inserting memory modules into commercially available PROM programmer. The 1747-M15 Series B adapter socket is required for use with the memory module (catalog number 1747-M13).
