The designation \"CJ1G\" references the high-speed backplane processing tier, while the \"P\" suffix identifies embedded process controller capabilities that run up to 300 function blocks. The \"44\" memory configuration provides 30 Ksteps of sequence memory and 64 Kwords of system data memory (DM: 32 Kwords, EM: 32 Kwords x 1 bank), enabling control of up to 1280 local I\/O points across expanded backplane assemblies.\u003c\/p\u003e\n\u003ch3\u003eHardware Operating Limits\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eCJ1G-CPU44P\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eOmron\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e160 mm x 130 mm x 90 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e0.95 A at 5 VDC (Backplane)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O Capacity\u003c\/td\u003e\n\u003ctd\u003e1280 points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProgram Capacity\u003c\/td\u003e\n\u003ctd\u003e30 Ksteps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Memory Capacity\u003c\/td\u003e\n\u003ctd\u003e64 K words (DM: 32 K words, EM: 32 K words x 1 bank)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoop Function Blocks\u003c\/td\u003e\n\u003ctd\u003e300 blocks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eDeterministic Bus Execution \u0026amp; Firmware Mapping\u003c\/h3\u003e\n\u003cp\u003eThe processor maintains synchronous cyclic updates across the internal CJ-series backplane bus communication velocity framework.
