The manufacturer and device codes may also be read via the command register, for instances when the

MBM29LV001TC/BC are erased or programmed in a system without access to high voltage on the A9 pin. The

command sequence is illustrated in Table 6. (Refer to Autoselect Command section.)

Byte 0 (A0 = VIL) represents the manufacturer’s code (Fujitsu = 04H) and (A0 = VIH) represents the device identifier

code (MBM29LV001TC = EDH and MBM29LV001BC = 6DH). These two bytes/words are given in the tables 3.1

and 3.2. All identifiers for manufactures and device will exhibit odd parity with DQ7 defined as the parity bit. In

order to read the proper device codes when executing the autoselect, A1 must be VIL. (See Tables 3.1 and 3.2.)
