■ FUNCTIONAL DESCRIPTION
This device supports asynchronous read, page read & normal write operation and synchronous burst read and
burst write operation for faster memory access and features 3 kinds of power down modes for power saving as
user configurable option.
• Power-up
It is required to follow the power-up timing to start executing proper device operation. Refer to "Power-up Timing".
After Power-up, the device defaults to asynchronous page read & normal write operation mode with sleep power
down feature.
• Configuration Register
The Configuration Register(CR) is used to configure the type of device function among optional features. Each
selection of features is set through CR set sequence after power-up. If CR set sequence is not performed after
power-up, the device is configured for asynchronous operation with sleep power down feature as default configuration.
• CR Set Sequence
The CR set requires total 6 read/write cycles with unique address. Operation other than read/write operation
requires that device being in standby mode. Following table shows the detail sequence.

Read Data (RDb)
The first cycle is to read from most significant address(MSB).
The second and third cycles are to write to MSB. If the second or third cycle is written into the different address,
the CR set is cancelled and the data written by the second or third cycle is valid as a normal write operation. It
is recommended to write back the data(RDa) read by first cycle to MSB in order to secure the data.
The forth and fifth cycles are to write to MSB. The data of forth and fifth cycle is don't-care. If the forth or fifth
cycle is written into different address, the CR set is also cancelled, but write data may not be written as normal
write operation.
The last cycle is to read from specific address key for mode selection. And read data(RDb) is invalid.
Once this CR set sequence is performed from an initial CR set to the other new CR set, the written data stored
in memory cell array may be lost. So, it should perform the CR set sequence prior to regular read/write operation
if necessary to change from default configuration.

• Power Down
The Power Down is low power idle state controlled by CE2. CE2 Low drives the device in power down mode
and maintains low power idle state as long as CE2 is kept Low. CE2 High resumes the device from power down
mode.
This device has 3 power down modes, Sleep, 4 M-bit Partial, and 8 M-bit Partial.
The selection of power down mode is set through CR set sequence. Each mode has following data retention
features.

N/A
4 M-bit Partial
4 M bits
000000h to 03FFFFh
8 M-bit Partial
8 M bits
000000h to 07FFFFh
The default state after power-up is Sleep and it is the lowest power consumption but all data will be lost once
CE2 is brought to Low for Power Down. It is not required to perform CR set sequence to set to Sleep mode after
power-up in case of asynchronous operation.
• Burst Read/Write Operation
Synchronous burst read/write operation provides faster memory access that synchronized to microcontroller or
system bus frequency. Configuration Register(CR) Set is required to perform burst read & write operation after
power-up. Once CR set sequence is performed to select synchronous burst mode, the device is configured to
synchronous burst read/write operation mode with corresponding RL and BL that is set through CR set sequence
together with operation mode. In order to perform synchronous burst read & write operation, it is required to
control new signals, CLK, ADV and WAIT that Low Power SRAMs do not have.

• CLK Input Function
The CLK is input signal to synchronize memory to microcontroller or system bus frequency during synchronous
burst read & write operation. The CLK input increments device internal address counter and the valid edge of
CLK is referred for latency counts from address latch, burst write data latch, and burst read data output. During
synchronous operation mode, CLK input must be supplied except for standby state and power down state. CLK
is Don't care during asynchronous operation.
• ADV Input Function
The ADV is input signal to latch valid address. It is applicable to synchronous operation as well as asynchronous
operation. ADV input is active during CE1 = L and CE1 = H disables ADV input. All addresses are determined
on the rising edge of ADV.
During synchronous burst read/write operation, ADV = H disables all address inputs. Once ADV is brought to
High after valid address latch, it is inhibited to bring ADV Low until the end of burst or until burst operation is
terminated. ADV Low pulse is mandatory for synchronous burst read/write operation mode to latch the valid
address input.
During asynchronous operation, ADV = H also disables all address inputs. ADV can be tied to Low during
asynchronous operation and it is not necessary to control ADV to High.
10
MB82DBS02163C-70L
• WAIT Output Function
The WAIT is output signal to indicate data bus status when the device is operating in synchronous burst mode.
During burst read operation, WAIT output is enabled after specified time duration from OE = L or CE1 = L
whichever occurs last. WAIT output Low indicates data output at next clock cycle is invalid, and WAIT output
becomes High one clock cycle prior to valid data output. During continuous burst read operation, an additional
output delay may occur when a burst sequence crosses it's device-row boundary. The WAIT output notifies this
delay to controller. Refer to the section "Burst Length" for the additional delay cycles in details. During OE read
suspend, WAIT output does not indicate data bus status but carries the same level from previous clock cycle
(kept High) except for read suspend on the final data output. If final read data output is suspended, WAIT output
becomes high impedance after specified time duration from OE = H.
During burst write operation, WAIT output is enabled to High level after specified time duration from WE = L or
CE1 = L whichever occurs last and kept High for entire write cycles including WE write suspend. The actual
write data latching starts on the appropriate clock edge with respect to Valid Clock Edge, Read Latency, and
Burst Length. During WE Write suspend, WAIT output does not indicate data bus status but carries the same
level from previous clock cycle (kept High) except for write suspend on the final data input. If final write data
input is suspended, WAIT output becomes high impedance after specified time duration from WE = H.
The burst operation is always started after fixed latency with respect to Read Latency set in CR.
When the device is operating in asynchronous mode, WAIT output is always in High Impedance.
11
MB82DBS02163C-70L
• Latency
Read Latency (RL) is the number of clock cycles between the address being latched and first read data becoming
available during synchronous burst read operation. It is set through CR set sequence after power-up. Once
specific RL is set through CR set sequence, write latency, that is the number of clock cycles between address
being latched and first write data being latched, is automatically set to RL-1. The burst operation is always started
after fixed latency with respect to Read Latency set in CR.

• Address Latch by ADV
The ADV latches valid address presence on address inputs. During synchronous burst read/write operation
mode, all the address are determined on the rising edge of ADV when CE1 = L. The specified minimum value
of ADV = L setup time and hold time against valid edge of clock where RL count is begun must be satisfied.
Valid address must be determined with specified setup time against either the falling edge of ADV or falling edge
of CE1 whichever comes late. And the determined valid address must not be changed during ADV = L period.
• Burst Length
Burst Length is the number of word to be read or written during synchronous burst read/write operation as the
result of a single address latch cycle. It can be set on 8,16 words boundary or continuous for entire address
through CR set sequence. The burst type is sequential that is incremental decoding scheme within a boundary
address. Starting from initial address being latched, device internal address counter assigns +1 to the previous
address until reaching the end of boundary address and then wrap round to least significant address (= 0). After
completing read data output or write data latch for the set burst length, operation automatically ended except
for continuous burst length. When continuous burst length is set, read/write is endless unless it is terminated by
the rising edge of CE1. During continuous burst read, an additional output delay may occur when a burst
sequence cross it's device-row boundary. This is the case when A0 to A6 of starting address is either 7Dh, 7Eh,
or 7Fh as shown in the following table. The WAIT signal indicates this delay.

• Single Write
Single write is synchronous write operation with Burst Length = 1. The device can be configured either to "Burst
Read & Single Write" or to "Burst Read & Burst Write" through CR set sequence. Once the device is configured
to "Burst Read & Single Write" mode, the burst length for synchronous write operation is always fixed 1 regardless
of BL values set in CR, while burst length for read is in accordance with BL values set in CR.

• Burst Read Suspend
Burst read operation can be suspended by OE High pulse. During burst read operation, OE brought to High
from Low suspends burst read operation. Once OE is brought to High with the specified setup time against clock
where the data being suspended, the device internal counter is suspended, and the data output becomes high
impedance after specified time duration. It is inhibited to suspend the first data output at the beginning of burst
read.
OE brought to Low from High resumes burst read operation. Once OE is brought to Low, data output becomes
valid after specified time duration, and internal address counter is reactivated. The last data output being suspended as the result of OE = H and first data output as the result of OE = L are from the same address.
In order to guarantee to output last data before suspension and first data after resumption, the specified minimum
value of OE hold time and setup time against clock edge must be satisfied respectively.

• Burst Write Suspend
Burst write operation can be suspended by WE High pulse. During burst write operation, WE brought to High
from Low suspends burst write operation. Once WE is brought to High with the specified setup time against
clock where the data being suspended, device internal counter is suspended, data input is ignored. It is inhibited
to suspend the first data input at the beginning of burst write.
WE brought to Low from High resumes burst write operation. Once WE is brought to Low, data input becomes
valid after specified time duration, and internal address counter is reactivated. The write address of the cycle
where data being suspended and the first write address as the result of WE = L are the same address.
In order to guarantee to latch the last data input before suspension and first data input after resumption, the
specified minimum value of WE hold time and setup time against clock edge must be satisfied respectively.
Burst write suspend function is available when the device is operating in WE level controlled burst write only.

• Burst Read Termination
Burst read operation can be terminated by CE1 brought to High. If BL is set on Continuous, burst read operation
is continued endless unless terminated by CE1 = H. It is inhibited to terminate burst read before first data output
is completed. In order to guarantee last data output, the specified minimum value of CE1 = L hold time from
clock edge must be satisfied. After termination, the specified minimum recovery time is required to start new
access.
