DESCRIPTION (cont’d)

The DU (Don’t Use) pin does not affect the function

of the memory and it is reserved for use by SGS-

THOMSON during test sequences.The pin may be

left unconnected or may be connected to VCC or

VSS. Direct connection of DU to VSS is recom-

mended for the lowest standby power consump-

tion.

MEMORY ORGANIZATION

The ST93C06 is organized as 32 bytes x 8 bits or

16 words x 16 bits. If the ORG input is left uncon-

nected (or connected to VCC) the x16 organization

is selected, when ORG is connected to Ground

(VSS) the x8 organization is selected. When the

ST93C06 is in standby mode, the ORG input

should be unconnected or set to either VSS or VCC

in order to achieve the minimum power consump-

tion. Any voltage between VSS and VCC applied to

ORG may increase the standby current value.
