REGISTER CKE POWER DOWN WITH IBT OFF
Upon entry into CKE Power Down mode with IBT off, all register input buffers including IBT are disabled except for CK/CK,
DCKEn, FBIN/FBIN, and RESET. The SSTE32882HLB disables input buffers within tInDIS clocks after latching both
DCKEn Low. In order to eliminate and false parity check error, the PAR_IN input buffer has to be kept active for 1 tCK after
Address and Command input buffers disabled. After tInDIS, the register can tolerate floating input except for CK/CK, DCKEn
and RESET. The SSTE32882HLB also disables all its output buffers except for Yn/Yn, QxODTn, QxCKEn and
FBOUT/FBOUT. The Yn/Yn and FBOUT/FBOUT outputs continue to drive a valid phase accurate clock signal. The
QxODTn and QxCKEn outputs are driven Low. The register output buffers are Hi-Z tQDIS clock after QxCKEn is driven Low.
This is shown in the next figure.
Power Down Mode Entry and Exit with IBT Off
(1) i, j only apply for QuadCS capable register. When QuadCS is enabled, i = 2, j = 3.
(2) QuadCS disabled: During CKE Power Down Entry/Exit, driving DCS[1,0] LOW is illegal as it will force SSTE32882 into
Register Control Word access mode.
(3)Upon CKE Power Down exit, QxCSn will be held HIGH for maximum of 1 tCK regardless of what DCSn input level is. For
all other operation QxCSn outputs will follow DCSn inputs.
