of these standby modes.
When using the RESET pin only, a CMOS standby mode is achieved with RESET input held at V
= “H” or “L”) . Under this condition the current is consumed is less than 5 μA Max Once the RESET pin is taken
high, the device requires t
In the standby mode the outputs are in the high impedance state, independent of the OE input.
• Automatic Sleep Mode
There is a function called automatic sleep mode to restrain power consumption during read-out of
MBM29DL32XTE/BE data. This mode can be used effectively with an application requested low power con-
sumption such as handy terminals.
To activate this mode, MBM29DL32XTE/BE automatically switch themselves to low power mode when
MBM29DL32XTE/BE 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 μA (CMOS Level) .
During simultaneous operation, V
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 MBM29DL32XTE/BE read-out the data for changed addresses.

• 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
