NOTES:
1. "H" = V
IH, "L" = VIL, "X" = Don't Care.
2. Read and write operations are controlled by the appropriate setting of R/W, CE
0, CE1, BEn and OE.
3. Outputs are in Pipelined mode: the data out will be delayed by one cycle.
4. ADS and CNTRST are independent of all other memory control signals including CE
0, CE1 and BEn
5. The address counter advances if CNTEN = V
IL on the rising edge of CLK, regardless of all other memory control signals including CE0, CE1, BEn.
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated
in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. V
TERM must not exceed VDD + 150mV for more than 25% of the cycle time or
4ns maximum, and is limited to
< 20mA for the period of VTERM > VDD + 150mV.
NOTES:
1. Industrial temperature: for specific speeds, packages and powers contact your
sales office.
