DEVICE OPERATION
SILICON ID READ
The Silicon ID Read mode allows the reading out of a
binary code from the device and will identify its manu-
facturer and type. This mode is intended for use by
programming equipment for the purpose of automatically
matching the device to be programmed with its corre-
sponding programming algorithm. This mode is func-
tional over the entire temperature range of the device.
To activate this mode, the two cycle "Silicon ID Read"
command is requested. (The command sequence is il-
lustrated in Table 14.

During the "Silicon ID Read" Mode, manufacturer's code
(MXIC=C2H) can be read out by setting A0=VIL and
device identifier can be read out by setting A0=VIH.
To terminate the operation, it is necessary to write the
read command. The "Silicon ID Read" command func-
tions independently of the VPEN voltage. This command
is valid only when the WSM is off.
