Read Mode
The MBM29LV080 has two control functions which must be satisfied in order to obtain data at the outputs. CE is
the power control and should be used for a device selection. OE is the output control and should be used to gate
data to the output pins if a device is selected.
Address access time (t
ACC
) is equal to the delay from stable addresses to valid output data. The chip enable access
time (t
CE
) is the delay from stable addresses and stable CE to valid data at the output pins. The output enable access
time is the delay from the falling edge of OE to valid data at the output pins. (Assuming the addresses have been
stable for at least t
ACC
-t
OE
time.)
Standby Mode
There are two ways to implement the standby mode on the MBM29LV080 device, one using both the CE and
RESET pins; the other via the RESET pin only.
When using both pins, a CMOS standby mode is achieved with CE and RESET inputs both held at V
CC
±
0.3 V.
Under this condition the current consumed is less than 5
μ
A. A TTL standby mode is achieved with CE and RESET
pins held at V
IH
. Under this condition the current is reduced to approximately 250
μ
A. The device can be read with
standard access time (t
CE
) from either of these standby modes.
When using the RESET pin only, a CMOS standby mode is achieved with RESET input held at V
SS
±
0.3 V (CE =“H”
or “L”). Under this condition the current consumed is less than 5
μ
A. A TTL standby mode is achieved with pin held
at V
IL
(CE =“H” or “L”). Under this condition the current required is reduced to approximately 250
μ
A. Once the
RESET pin is taken high, the device requires 500 ns of wake up time before outputs are valid for read access.
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 MBM29LV080
data.
This mode can be used effectively with application requested low power consumption such as handy terminals.
To active this mode, MBM29LV080 automatically switches itself to low power mode when MBM29LV080 addresses
remain stably during access time of 300 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).
Since the data latched during this mode, the data are read-out continuously. If the addresses are changed, the
mode is canceled automatically and MBM29LV080 read-out the data for changed addresses.
Output Disable
With the OE input at a logic high level (V
IH
), output from the device is 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 device and will identify its manufacturer and
type. This mode is intended for use by programming equipment for the purpose of automatically matching the device
to be programmed with its corresponding Programming Algorithm. This mode is functional over the entire temper-
ature range of the device.
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 device outputs by toggling address A
0
from V
IL
to V
IH
. All addresses are
DON’T CARES except A
0
, A
1
, A
6
and A
10
. (See Table 3.)
