Legend:
X = Don’t Care, where Don’t Care is either V_IL or V_IH levels. See DC Characteristics for voltage levels of normal TTL or CMOS
input levels.
Notes:
Volt-only?
1. V_PP pins are not connected in the 5.0 V-Only Flash Memory Card.
2. In this x8 mode, A0 = V_IL outputs or inputs the “even” byte (low byte) of the x16 word on D0–D7.
3. Only even-byte data is valid during Attribute Memory Read function.
4. During Attribute Memory Read function, REG and OE must be active for the entire cycle.
5. During Attribute Memory Write function, REG and WE must be active for the entire cycle, OE must be inactive for the entire
cycle.
6. Standby current is I_CCS.
