MX29F1611
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
manufacturer and type. This mode is intended for use by
programming equipment for the purpose of automatically
matching the device to be programmed with its
corresponding programming algorithm. This mode is
functional over the entire temperature range of the
device.
To activate this mode, the programming equipment must
force VID (11.5V~12.5V) on address pin A9. Two
identifier bytes may then be sequenced from the device
outputs by toggling address A0 from VIL to VIH. All
addresses are don't cares except A0 and A1.
The manufacturer and device codes may also be read via
the command register, for instances when the
MX29F1611 is erased or programmed in a system
without access to high voltage on the A9 pin. The
command sequence is illustrated in Table 3.
Byte 0 (A0=VIL) represents the manfacturer's code
(MXIC=C2H) and byte 1 (A0=VIH) the device identifier
code (MX29F1611=F7H).
To terminate the operation, it is necessary to write the
read/reset command sequence into the CIR.

** Outputs C2H at protected sector address, 00H at unprotected scetor address.
***Only the top and the bottom sectors have protect-bit feature. Sector address = (A19, A18,A17,A16) = 0000B or 1111B
