Automatic Sleep Mode
There is a function called automatic sleep mode to restrain power consumption during read-out of
MBM29DL400TC/BC data. This mode can be used effectively with an application requested low power
consumption such as handy terminals.
To activate this mode, MBM29DL400TC/BC automatically switch themselves to low power mode when
MBM29DL400TC/BC addresses remain stably during access fine of 150 ns. It is not necessary to control CE,
WE, and OE on the mode. Under the mode, the current consumed is typically 1
μ
A (CMOS Level).
During simultaneous operation, V
CC
active current (I
CC2
) is required.
Since the data are latched during this mode, the data are read-out continuously. If the addresses are changed,
the mode is canceled automatically and MBM29DL400TC/BC read-out the data for changed addresses.
Output Disable
With the OE input at a logic high level (V
IH
), output from the devices are disabled. This will cause the output pins
to be in a high impedance state.
Autoselect
The autoselect mode allows the reading out of a binary code from the devices and will identify its manufacturer
and type. This mode is intended for use by programming equipment for the purpose of automatically matching
the devices to be programmed with its corresponding programming algorithm. This mode is functional over the
entire temperature range of the devices.
To activate this mode, the programming equipment must force V
ID
(11.5 V to 12.5 V) on address pin A
9
. Two
identifier bytes may then be sequenced from the devices outputs by toggling address A
0
from V
IL
to V
IH
. All
addresses are DON’T CARES except A
0
, A
1
, and A
6
(A
-1
). (See Tables 2 and 3.)
The manufacturer and device codes may also be read via the command register, for instances when the
MBM29DL400TC/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 8. (Refer to Autoselect Command section.)
Word 0 (A
0
= V
IL
) represents the manufacturer’s code (Fujitsu = 04H) and word 1 (A
0
= V
IH
) represents the device
identifier code (MBM29DL400TC = 0CH and MBM29DL400BC = 0FH for
×
8 mode; MBM29DL400TC = 220CH
and MBM29DL400BC = 220FH for
×
16 mode). These two bytes/words are given in the tables 5.1 and 5.2. 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 5.1 and 5.2.)
In case of applying V
ID
on A
9
, since both Bank 1 and Bank 2 enters Autoselect mode, the simultenous operation
can not be executed.
