TIMING REQUIREMENTS
Table 14: Asynchronous READ Cycle Timing Requirements
All tests performed with outputs configured for default setting of half drive strength, (BCR[5:4] = 01b).
Note:
1. The High-Z timings measure a 100mV transition from either V
2. The Low-Z timings measure a 100mV transition away from the High-Z (VccQ/2) level toward either V
3. Page mode enabled only.
4. Contact EMLSI for specific timing.
