The manufacturer and device codes may also be read via the command register, for instances when the
MBM29LV400TC/BC are erased or programmed in a system without access to high voltage on the A
9
pin. The
command sequence is illustrated in Table 7. (Refer to Autoselect Command section.)
Byte 0 (A
0
= V
IL
) represents the manufacturer’s code (Fujitsu = 04H) and (A
0
= V
IH
) represents the device identifier
code (MBM29LV400TC = B9H and MBM29LV400BC = BAH for
×
8 mode; MBM29LV400TC = 22B9H and
MBM29LV400BC = 22BAH 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
7
defined as the parity bit. In order to read the proper
device codes when executing the autoselect, A
1
must be V
IL
. (See Tables 4.1 and 4.2.)
*1: A
-1
is for Byte mode.
*2: Outputs 01H at protected sector addresses and outputs 00H at unprotected sector addresses.
(B): Byte mode
(W): Word mode
