... ST93C46A/46C/46T, ST93C47C/47T MEMORY ORGANIZATION The ST93C46 is organised as 128 bytes x 8 bits or 64 words x 16 bits. If the ORG input is left uncon- nected (or connected the x16 organization CC is selected, when ORG is connected to Ground (V ) the x8 organization is selected. When the SS ST93C46 is in standby mode, the ORG input should be unconnected or set to either V in order to get minimum power consumption ...
