5 1 Inroducion 1.1. General Descripion Preec high performance SRAM cards conform o he PCMCIA / JEIDA inernaional sandard and consis of muliple very low power consumpion CMOS SRAM ICs, decoder IC and power conrol IC mouned on a very hin prined circui board using surface mouning echnology. Wih he dual back-up baery design, each SRAM card conains a replaceable bu non-rechargeable 3V lihium baery (main baery) and an on-board rechargeable bu non-replaceable baery (auxiliary baery) for daa reenion. This design allows replacemen of main baery wihou daa loss for 20 minues approximaely. Digial signals on he BVD1*/BVD2* pins were used o alarm he user wheher he main baery should be replaced o preven he sored daa from loss. Wih he flexible and user-friendly design, boh BR2325 and CR2025 can be used as main baery. There is baery case lock sysem o preven baery dropping from he card. Also, wih he wrie-proec swich design, daa will no be wrien ino he card by acciden. Memory card aribue informaion represens various aribue informaion of a card and is sored a EVEN address of an aribue memory space which is enabled by assering REG* signal. Regarding o he aribue informaion forma, please refer o he PCMCIA 2.0 or JEIDA 4.1 specificaion. Wih he flexible design of his series cards, hey provide 8K byes E2PROM available for aribue memory or here is no aribue memory Feaures Inerface: PCMCIA / JEIDA sandard Capaciy: 256K byes ~ 8M byes Daa bus selecable: Bye (x8) / word (x16) Buil-in wrie proec swich Credi card size: 54.0 x 85.6 x 3.3 (mm) Fas access ime: 120ns (maximum) Aribue memory: 8 KB (opional 2KB/0KB by special reques) Single +5V operaing volage Connecor ype: 2-piece, 2-row, 68 pins Baery: Dual back-up baery design Boh BR2325 and CR2025 used as main baery Baery volage deecion funcion Baery case lock sysem Preliminary Version 12 Page5
