OVERVIEW
The LPM/MCM-USSD is an I/O mapped, universal STD Bus Solid State Disk (SSD). It can be populated by the user with up to 4 megabytes of RAM, EPROM, or PEROM (flash). The card allows a user to substitute onboard semiconductor devices in applications where the environment is too harsh for mechanical hard disks or floppy disk drives, plus it has significant speed advantages. It is designed to store programs and data for applications such as data collection and logging, diagnostics, etc.
The MCM prefix on the card designates a standard STD Bus board. The LPM prefix designates a CMOS STD Bus board. A MCM/LPM prefix indicates the card has the same features and functionality and is available in both CMOS and regular NMOS/TTL logic. The differences between these two are the power requirements and operational temperature range.
