Processor and memory

The RMC processor is available in two speeds, 300 MHZ or 720 MHZ, depending on the embedded
software on the purchased system. The RMC standard system runs at 720 MHZ with full application
support. The RMC-LITE system runs at 300 MHZ and supports a lesser number of applications. To
determine the speed of your system or details on the embedded software part numbers, see section
8.4 Update device software.

Component Description
Flash 32-bit flash (flash device software image, configuration and measurement data)
RAM 256 MB RAM storage
Clocks TCXO 32.768 k Oscillator to ensure accurate clocks (+/- 5 ppm accuracy, 5 ppm
drift over time). Standard 50 ppm Oscillator at 25 MHZ to generate the core and
peripheral clocks
2.2.2 Communication ports
Communication ports provide communication between the RMC and host systems or external devices.
Factory preconfigured ports support typical communication scenarios. The ports support several
available communication protocols.
Ports configured for local communication (direct connection) support either local access from a host
system, or connection to external devices or peripherals (measurement transmitters, additional
automation or control equipment, flow computers or analyzers).
Ports configured for remote communication connect the RMC to a communication network and allow
remote access or management over that network.
