Notes
8. Pulse width < 20 ns.
9. Industrial parts are available in CY7C028V and CY7C038V, CY7C027V/027AV only.
10. fMAX = 1/tRC = All inputs cycling at f = 1/tRC (except output enable). f = 0 means no address or control lines change. This applies only to inputs at CMOS level standby ISB3.
11. Tested initially and after any design or process changes that may affect these parameters.
