* MX29L3211 Manufacturer Code = C2H, Device Code = F9H when BYTE = VIL
MX29L3211 Manufacturer Code = 00C2H, Device Code = 00F9H when BYTE = VIH
** Outputs C2H at protected sector address, 00H at unprotected scetor address.
***Only the top and the bottom sectors have protect-bit feature. Sector address = (A20, A19, A18,A17,A16) = 00000B or 11111B
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
MX29L3211 is erased or programmed in a system
without access to high voltage on the A9 pin. The
command sequence is illustrated in Table 3.
During the "Silicon ID Read" Mode, manufacturer's code
(MXIC=C2H) can be read out by setting A0=VIL and
device identifier (MX29L3211=F9H) can be read out by
setting A0=VIH.
To terminate the operation, it is necessary to write the
read/reset command sequence into the CIR.
