bordino schede

CHMM7000

The Crash Hardened Memory Module is a solid state memory (FLASH) enclosed in a rugged, hardened chassis compliant to the Railways Standards. The solid state memory has a USB communicati on interface (Ethernet interface under development) and it can be used as a storage disk by the CPU to store and retrieve data such as: equipment diagnostic data, operating (driving) data, dynamic data (e.g. speed, brake, battery voltage) as well identification and configuration data.
The data are stored in files on a standard journaling file system.
In case of accident or when necessary, the data stored can be easily downloaded using a PC.
The maximum memory size is 32 GB. The built in memory controller is in charge of: wear-levelling bad block management, error correction coding, data integrity under power-cycling and communication.
