Notes:
1. When using extended memory timing add 2 TpC
2. Timing numbers given are for minimum TpC
3. The V
CC
voltage specification of 5.5V guarantees 5.0V +/- 0.5V and
the V
CC
voltage specification of 3.5V guarantees 3.5V only
Standard Test Load
All timing references use 0.7 V
CC
for a logic 1 and 0.2 V
CC
for a logic 0
For Standard Mode (not Low-EMI Mode for outputs) with SMR D1 = 0, D0 = 0
