NOTES:
2721 tbl 10b
1. Transition is measured 0mV from Low or High-impedance voltage with Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization but is not production tested.
3. To access SRAM, CE = V IL and SEM = V IH . To access semaphore, CE = V IH and SEM = V IL. Either condition must be valid for the entire t EW time.
4. The specification for t DH must be met by the device supplying write data to the SRAM under all operating conditions. Although t DH and t OW values will vary over voltage and
temperature, the actual t DH will always be smaller than the actual t OW .
5. 'X' in part number indicates power rating (SA or LA).
