PRELIMINARY
Write Cycle No. 3 (Chip Enable Controlled)
AC Electrical Characteristics
* VCC = 3.3V +5%
NOTES: (For two previous Electrical Characteristics tables)
1. The parameter is tested with CL = 5 pF as shown in Figure 2. Transition is measured
±200 mV from steady state voltage.
2. At any given temperature and voltage condition, tHZCE is less than tLZCE.
3. This parameter is sampled.
4. WE is high for a READ cycle.
5. The device is continuously selected. All the Chip Enables are held in their active state.
6. The address is valid prior to or coincident with the latest occuring Chip Enable.
