Module type: CPU Daughter Board Memory Expansion Board (CMOS RAM)

Applicable objects: IC697CP771, IC697CP772, IC697PCM711 co processors, directly plugged into the CPU/PCM body, sharing the same rack slot without occupying additional VME slots

Storage capacity: 256K bytes CMOS RAM, can be used for program logic storage+data storage, software allocation purposes

Other models in the same series:

IC697MEM713：64KB

IC697MEM715：128KB

IC697MEM719：512KBQualitrol

Status: The original factory has stopped production, and the market is circulating dismantled/refurbished inventory parts

Electrical and Power Consumption

Power supply: taken from the 5V bus of the CPU backplane

Power consumption: 1.1W

Memory power failure maintenance: relies on CPU/PCM body lithium battery IC697ACC701, the module itself does not have a battery

Battery life: nominal shelf life of 10 years at 20 ℃ environment; Power outage data storage typically lasts for 6 months, and memory program data may be lost due to battery aging
