AC Electrical Characteristics Over the
Operating Temperature and Supply Voltage
NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with the Ouput Test Load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested.
3. To access SRAM, CE = V
4. 'X' in part number indicates power rating (SA or LA).
5. Port-to-port delay through RAM cells from writing port to reading port, refer to “Timing Waveform of Write with Port-to-Port Read”.
