Characteristics subject to change without notice
WRITE OPERATIONS
The following operations are initiated by observing the
sequence specified in the Write Command Table.
Read Mode
The device can be put into a standard READ mode by
initiating a write cycle with 00H on the data bus. The
subsequent read cycles will be performed similar to a
standard EPROM or E2PROM Read.
Signature Mode
An alternative method for reading device signature (see
Read Operations Signature Mode), is initiated by writing
the code 90H into the command register while keeping
VPP high. A read cycle from address 0000H with CE and
OE low (and WE high) will output the device signature.
CATALYST Code = 00110001 (31H)
A Read cycle from address 0001H retrieves the binary
code for the device on outputs I/O0 to I/O7.
28F010 Code = 1011 0100 (B4H)
