MX29F1610
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
MX29F1610 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 (MX29F1610=F1H).
To terminate the operation, it is necessary to write the
read/reset command sequence into the CIR.
