AC CHARACTERISTICS
External I/O or Memory Read and Write Timing
Z86C61/62/96 (16 MHz)
Notes:
Standard Test Load
All timing references use 2.0 V for a logic 1 and 0.8 V for a logic 0.
DS97Z8X1600
1. When using extended memory timing add 2 TpC.
2. Timing numbers given are for minimum TpC.
3. See clock cycle dependent characteristics table.
