DESCRIPTION Mitsubishi’s Static RAM cards provide large memory capacities on a device approximately the size of a credit card(85.6mm × 54mm × 3.3mm). T h e c a r d s u s e a 8 / 1 6 bit data bus.The devices use a replaceable lithium battery to maintain data. Available in 64K byte-4M byte capacities, Mitsubishi’s Static RAM cards are available with a 68-pin, two-piece connector. FEATURES Uses TSOP (Thin Small Outline Package) to achieve very high memory density coupled with high reliability, without enlarging card size PRODUCT LIST

WRITE PROTECT MODE (WP) When the write protect switch is switched on, this card goes into a write protect mode that can read but not write data. In this mode, the WP pin becomes “H” level. At the shipment the write protect switch is switched off (Normal mode : The card can be written ; WP pin indicates “L” level).
