It mounts directly onto compatible host controller or coprocessor modules to expand user program logic capacity and data table storage without consuming an additional backplane slot in the rack.\u003c\/p\u003e\n\u003cp\u003eMemory stored on the IC697MEM715D is protected against power interruptions by the backup lithium battery mounted on the host module baseboard housing. The memory architecture supports full error checking, utilizing a continuous background checksum routine when installed on a CPU, or power-cycle and reset validation routines when paired with a coprocessor. The module is field installable and complies with VME standard C.1 architecture.\u003c\/p\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\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eCMOS Expansion Memory Daughterboard\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCatalog Number\u003c\/td\u003e\n      \u003ctd\u003eIC697MEM715D\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePlatform\u003c\/td\u003e\n      \u003ctd\u003eSeries 90-70\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMemory Capacity\u003c\/td\u003e\n      \u003ctd\u003e128 Kbytes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMemory Technology\u003c\/td\u003e\n      \u003ctd\u003eBattery-backed CMOS RAM\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRack Space Required\u003c\/td\u003e\n      \u003ctd\u003e0 slots (daughterboard configuration)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eData Retention\u003c\/td\u003e\n      \u003ctd\u003e6 months nominal without external power (via host battery)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSupported Battery Type\u003c\/td\u003e\n      \u003ctd\u003eIC697ACC701 Lithium Battery (located on host baseboard)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eError Checking\u003c\/td\u003e\n      \u003ctd\u003eBackground checksum routine (CPU) \/ reset \u0026amp; power-cycle check (PCM)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eStandard Compliance\u003c\/td\u003e\n      \u003ctd\u003eVME Standard C.1\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMounting Method\u003c\/td\u003e\n      \u003ctd\u003eDirect plug-in daughterboard onto host module\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eThe IC697MEM715D is designed to integrate exclusively with specific Series 90-70 host baseboards:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentral Processing Units:\u003c\/strong\u003e Compatible with CPU 771 (IC697CPU771) and CPU 772 (IC697CPU772).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoprocessor Modules:\u003c\/strong\u003e Compatible with the Programmable Coprocessor Module (IC697PCM711).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery Interface:\u003c\/strong\u003e Utilizes the host module IC697ACC701 lithium battery connector for nonvolatile data retention.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cp\u003eThe IC697MEM715D is a field-installable daughterboard that requires no tools for physical mounting. Installation requires powering down the rack and extracting the host CPU or PCM module from the chassis. Always observe electrostatic discharge (ESD) precautions before handling the daughterboard. Align the connector pins carefully to secure the memory board onto the baseboard option connector before reinserting the assembly into its designated rack slot. Following installation on a CPU, controller initialization via programming software is required to configure memory partitions.\u003c\/p\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":53770211557739,"sku":"IC697MEM715D","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/ic697mem715_1200x1200_75236f10-4978-4381-87fd-223ea7a137b3.jpg?v=1787738794","url":"https:\/\/www.plcprotech.com\/products\/general-electric-ic697mem715d-series-90-70-128-kb-cmos-expansion-memory-daughterboard","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
