AC CHARACTERISTICS
External I/O or Memory Read and Write Timing Table
Notes:
[1] When using extended memory timing add 2 TpC.
[2] Timing numbers given are for minimum TpC.
[3] See clock cycle dependent characteristics table.
Standard Test Load
All timing references use 2.0 V for a logic 1 and 0.8 V for a logic 0.
