*See Thermal Considerations section.
**For a high–speed 8–Clock access, th for Enable is determined as follows:
VDD = 3 to 4.5 V, fclk > 1.78 MHz: th = 4350 – (7500/fclk)
VDD = 4.5 to 5.5 V, fk > 2.34 MHz: th = 3300 – (7500/fclk)
where th is in ns and fclk is in MHz.
NOTES:
1. This restriction does NOT apply for fclk rates less than those listed above. For “slow” fclk rates, use the th limits in the above table.
2. This restriction does NOT apply for an access involving more than 8 Clocks. For > 8 Clocks, use the th limits in the above table.
