Not all compatible memory chips exhibit a low enough self-refresh current to meet the target current for
USB suspend mode (see Table 21). Two memory types have been suggested in Table 25, based on
limited evaluation by ST, however this does not constitute a full characterisation, and no guarantees can
be made that the self-refresh current consumption will match the target for USB suspend mode in all
cases. Please consult the memory manufacturer for precise information.

COST
Optional battery off switch when not in use
Only required for RS232
NOTES
Option 1 only
For camera with no RS232
R24 fitting depends on flicker frequency
Fit R51 or R52, not both
R25 fitting depends on flicker frequency
R31, 32, 33, 34, 35 only for RS232
R41 only required for option 2
Only for RS232
R50 only required for option 1
(would lose stored images)
Push button switches
camera with USB prodn. Test
Only required for option 2
Could use TO92 instead
VGA sensor (different foortprint to VV6410)
Only require U2 or U6
Future replacement STV0680A for VfW
SDRAM dual footprint is possible for U4 and U5
Preferred SDRAM has low self refresh Idd.
e.g. (16Mbit) LGM72V16162ET75
Hyundai
Micron
CIF sensor (different footprint to VV6500)
Only require U2 or U6
e.g. TELCOM TC54VC2702ECB
RICOH Rx5VLxxC SERIES
