The manufacturer and device codes may also be read via the command register, for instances when the
MBM29LV200TC/BC are erased or programmed in a system without access to high voltage on the A
command sequence is illustrated in Table 7. (Refer to Autoselect Command section.)
Byte 0 (A
code (MBM29LV200TC = 3BH and MBM29LV200BC = BFH for 8 mode; MBM29LV200TC = 223BH and
MBM29LV200BC = 22BFH for 16 mode). These two bytes/words are given in the tables 4.1 and 4.2. All identifiers
for manufactures and device will exhibit odd parity with DQ
device codes when executing the autoselect, A
-1
is for Byte mode.
