10 ns access time — bus margin in practice
The CY7C1011G30-10ZSXAT: The 10 ns access time governs how fast the memory can present data after the address is valid. Budget the trace delay and load capacitance on the data bus. Write cycle time is also 10 ns, so back-to-back writes at the same speed are possible without wait states, provided the controller meets the pulse-width requirements.
The 2.2V minimum supply also helps maintain data retention during brownout conditions down to that threshold.
