(1) Specification is for LS_CLK and LS_WDATA pins. Refer to LPSDR input rise slew rate and fall slew rate in Figure 6-3.

(2) Specification is for DMD_DEN_ARSTZ pin. Refer to LPSDR input rise and fall slew rate in Figure 6-3.

(3) Specification is for SubLVDS receiver time only and does not take into account commanding and latency after commanding.

(4) Window time derating example: 0.5-V/ns slew rate increases the window time by 0.7 ns, from 3 ns to 3.7 ns.

Low-speed interface is LPSDR and adheres to the Section 6.6 and AC/DC Operating Conditions table in JEDEC Standard No. 209B, Low Power Double Data Rate (LPDDR)JESD209B.
