At a 66 MHz bus clock (15 ns period) the part meets zero-wait-state operation if the controller's address-to-data setup fits within that window. For faster controllers, the 15 ns limit may insert one wait state per access.
The 1.65 V to 2.2 V supply range covers nominal 1.8 V rails with headroom on both sides — useful for designs that run the core at 1.8 V and need the SRAM to track the same rail without a separate regulator. No AEC-Q100 grade is listed, so this part is not qualified for automotive under-hood use.
