This single-slot CPU integrates 1 Mbyte of battery-backed CMOS RAM, providing 512 Kbytes dedicated to user application programs and data.\u003c\/p\u003e\n\u003cp\u003eEquipped with an 80486DX2 microprocessor, the IC697CPM790 ensures rapid execution times of 0.4 microseconds per Boolean function. Operating within the Series 90-70 rack-mounted backplane environment utilizing the VME C.1 standard format, the module communicates seamlessly with standard I\/O and smart option modules. It requires integration with a standalone C program containing TMR operating and autotest routines to function within high-reliability system configurations.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-slot Series 90-70 central processing unit with 64 MHz 80486DX2 microprocessor and hardware floating-point math coprocessor\u003c\/li\u003e\n  \u003cli\u003e1 Mbyte of battery-backed CMOS RAM memory board integrated directly onto the module, with 512 Kbytes allocated for user application programs\u003c\/li\u003e\n  \u003cli\u003eFlash memory for operating system firmware storage, allowing in-system updates via the serial port without module disassembly\u003c\/li\u003e\n  \u003cli\u003eSupports up to 12K discrete inputs\/outputs and 8K analog inputs\/outputs in simplex mode, alongside 2,048 voted discrete inputs\/outputs and 1,024 voted analog inputs\u003c\/li\u003e\n  \u003cli\u003eThree-position RUN\/STOP operation mode switch and front-panel memory protect keyswitch for enhanced security\u003c\/li\u003e\n  \u003cli\u003eFour diagnostic status LEDs providing real-time indication of module health, run status, output enablement, and memory protection state\u003c\/li\u003e\n  \u003cli\u003eRS-422\/RS-485 compatible serial port for programmer attachment and system communications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEmergency Shut-Down (ESD) safety systems\u003c\/li\u003e\n  \u003cli\u003eIndustrial fire and gas detection architecture\u003c\/li\u003e\n  \u003cli\u003eTriple Modular Redundancy (TMR) critical control loops\u003c\/li\u003e\n  \u003cli\u003eHigh-availability process automation and discrete manufacturing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eGeneral Electric\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCatalog Number \/ Exact Model\u003c\/td\u003e\n      \u003ctd\u003eIC697CPM790\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Family\u003c\/td\u003e\n      \u003ctd\u003eSeries 90-70 PLC \/ GMR Redundant CPU\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMicroprocessor\u003c\/td\u003e\n      \u003ctd\u003e64 MHz, 80486DX2 with 32-bit Floating Point Math Coprocessor\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eUser Memory\u003c\/td\u003e\n      \u003ctd\u003e1 Mbyte total battery-backed CMOS RAM (512 Kbytes available for user program and data)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eExecution Speed\u003c\/td\u003e\n      \u003ctd\u003e0.4 microseconds per Boolean function\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCurrent Draw (5V Bus)\u003c\/td\u003e\n      \u003ctd\u003e3.3 Amps nominal\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating Temperature Range\u003c\/td\u003e\n      \u003ctd\u003e0 to 60 Celsius (32 to 140 Fahrenheit) with 70 CFM forced air;
