Datasheet

The following timing numbers indicate when data is latched or driven onto the external
bus, relative to the Flexbus output clock (FB_CLK). All other timing relationships can be
derived from these values.
Table 26. Flexbus limited voltage range switching specifications
Num Description Min. Max. Unit Notes
Operating voltage 2.7 3.6 V
Frequency of operation — FB_CLK MHz
FB1 Clock period 20 — ns
FB2 Address, data, and control output valid — 11.5 ns
FB3 Address, data, and control output hold 0.5 — ns 1
FB4 Data and FB_TA input setup 8.5 — ns
FB5 Data and FB_TA input hold 0.5 — ns 2
1. Specification is valid for all FB_AD[31:0], FB_BE/BWEn, FB_CSn, FB_OE, FB_R/W,FB_TBST, FB_TSIZ[1:0], FB_ALE,
and FB_TS.
2. Specification is valid for all FB_AD[31:0] and FB_TA.
