STV0680B + VV6410/6411/6500
60/63
Version 3.4
Note:
Not all compatible memory chips exhibit a low enough self-refresh current to meet the target
current for USB suspend mode (see Table 17). Two memory types have been suggested in Table
18, 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
