MX28F2000P
COMMAND DEFINITIONS
When low voltage is applied to the VPP pin, the con-
tents of the command register default to 00H, enabling
read-only operation.
Placing high voltage on the VPP pin enables read/write
operations. Device operations are selected by writing
specific data patterns into the command register. Ta-
ble 1 defines these MX28F2000P register commands.
Table 2 defines the bus operations of MX28F2000P.

NOTES:
1. VPPL may be grounded, a no-connect with a resistor tied
to ground, or < VCC + 2.0V. VPPH is the programming
voltage specified for the device. When VPP = VPPL,
memory contents can be read but not written or erased.
2. Manufacturer and device codes may also be accessed
via a command register write sequence. Refer to Table
1. All other addresses don't care.
3. VID is the Silicon-ID-Read high voltage.(11.5V to 13v)
4. Read operations with VPP = VPPH may access array
data or Silicon ID codes.
5. With VPP at high voltage, the standby current equals ICC
+ IPP (standby).
6. Refer to Table 1 for valid Data-In during a write operation.
7. X can be VIL or VIH.
