MS81V05200
This version: Jun. 2001
(583,680-word × 10-bit) FIFO memory
GENERAL DESCRIPTION
The MS81V05200 is a 5.6Mb FIFO (First-In First-Out) memory designed for 583,680-words × 10-bit high-speed
asynchronous read/write operation.
The MS81V05200 is best suited for a field memory for digital TVs or LCD panels which require high-speed, large
memory, and is not designed for high end use in professional graphics systems, which require long term picture
storage and data storage.
The MS81V05200 is provided with independent control clocks to support asynchronous read and write operations.
Different clock rates are also supported, which allow alternate data rates between write and read data streams.
The first data read operation can be performed after 1600 ns + 4 cycles from read reset and the first data write
operation is enabled after 1600 ns + 4 cycles from write reset. Thereafter, the high-speed read/write operation is
possible every cycle time. Additionally, a write mask function by IE pin and a read-data skipping function by OE
pin implement image data processing easily.
The MS81V05200 provides high speed FIFO (First-in First-out) operation without external refreshing:
MS81V05200 refreshes its DRAM storage cells automatically, so that it appears fully static to the users.
Moreover, fully static type memory cells and decoders for serial access enable the refresh free serial access
operation, so that serial read and/or write control clock can be halted high or low for any duration as long as the
power is on. Internal conflicts of memory access and refreshing operations are prevented by special arbitration
logic.
The MS81V05200’s function is simple, and similar to a digital delay device whose delay-bit- length is easily set by
reset timing. The delay length and the number of read delay clocks between write and read, is determined by
externally controlled write and read reset timings. The MS81V05200 uses a thin and small 70-pin plastic TSOP.

PIN DESCRIPTION
Data Inputs: (DI0-9)
These pins are used for serial data inputs.
Write Reset: RSTW
The first positive transition of SWCK after RSTW becomes high resets the write address pointers to zero. RSTW
setup and hold times are referenced to the rising edge of SWCK.
Write Enable: WE
WE is used for data write enable/disable control. WE high level enables the input, and WE low level disables the
input and holds the internal write address pointer. There are no WE disable time (low) and WE enable time (high)
restrictions, because the MS81V05200 is in fully static operation as long as the power is on. Note that WE setup
and hold times are referenced to the rising edge of SWCK. The latency for the write operation control by WE is 4.
After write reset, WE must remain low for more than 1600 ns (tFWD). After write reset, the write operation at
address 0 is started after a time tWL form the cycle in which WE is brought high.
Input Enable: IE
IE is used to enable/disable writing into memory. IE high level enables writing. The internal write address pointer
is always incremented by cycling SWCK regardless of the IE level. Note that IE setup and hold times are
referenced to the rising edge of SWCK. The latency for the write operation control by IE is 4.
Data Out: (DO0-9)
These pins are used for serial data outputs.
Read Reset: RSTR
The first positive transition of SRCK after RSTR becomes high resets the read address pointers to zero.
RSTR setup and hold times are referenced to the rising edge of SRCK.
Read Enable: RE
The function of RE is to gate of the SRCK clock for incrementing the read pointer. When RE is high before the
rising edge of SRCK, the read pointer is incremented. When RE is low, the read pointer is not incremented. RE
setup times (tRENS and tRDSS) and RE hold times (tRENH and tRDSH) are referenced to the rising edge of the SRCK
clock.
The latency for the read operation control by RE is 4. After read reset, RE must remain low for more than 1600 ns
(tFRD). After read reset, the read data at address 0 is output after a time tRL from the cycle in which WE is brought
high.
Output Enable: OE
OE is used to enable/disable the outputs. OE high level enables the outputs. The internal read address pointer is
always incremented by cycling SRCK regardless of the OE level. Note that OE setup and hold times are referenced
to the rising edge of SRCK. The latency for the read operation control by OE is 4.
Serial Write Clock: SWCK
The SWCK latches the input data on chip when WE is high, and also increments the internal write address pointer.
Data-in setup time tDS, and hold time tDH are referenced to the rising edge of SWCK.
Serial Read Clock: SRCK
Data is shifted out of the data registers. It is triggered by the rising edge of SRCK when RE is high during a read
operation. The SRCK input increments the internal read address pointer when RE is high.
The three-state output buffer provides direct TTL compatibility (no pullup resistor required). Data out is the same
polarity as data in. The output becomes valid after the access time interval tAC that begins with the rising edge of
SRCK. *There are no output valid time restriction on MS81V05200.

OPERATION MODE
Write Operation Cycle
The write operation is controlled by four control signals, SWCK, RSTW, WE, and IE. The write operation is
accomplished by cycling SWCK, and holding WE high after the write address pointer reset operation or RSTW.
RSTW must be performed for internal circuit initialization before write operation. WE must be low before and
after the reset cycle (tLWE + tFWD).
Each write operation, which begins after RSTW must contain at least 231 active write cycles, i.e., SWCK cycles
while WE and IE are high.

Read Operation Cycle
The read operation is controlled by four control signals, SRCK, RSTR, RE, and OE. The read operation is
accomplished by cycling SRCK, and holding both RE and OE high after the read address pointer reset operation or
RSTR.
Each read operation, which begins after RSTR, must contain at least 231 active read cycles, i.e., SRCK cycles
while RE and OE are high. RE must be low before and after the reset cycle (tLRE + tFWD).

Old/New Data Access
There must be a minimum delay of 600 SWCK cycles between writing into memory and reading out from memory.
If reading from the first field starts with an RSTR operation, before the start of writing the second field (before the
next RSTW operation), then the data just written will be read out.
The start of reading out the first field of data may be delayed past the beginning of writing in the second field of
data for as many as 70 SWCK cycles. If the RSTR operation for the first field read-out occurs less than 70 SWCK
cycles after the RSTW operation for the second field write-in, then the internal buffering of the device assures that
the first field will still be read out. The first field of data that is read out while the second field of data is written is
called “old data”. In order to read out “new data”, i.e., the second field written in, read reset must be input after
write address 200 the delay between an RSTW operation and an RSTR operation must be at least 600 SRCK cycles.
If the delay between RSTW and RSTR operations is more than 71 but less than 600 cycles, then the data read out
will be undetermined. It may be “old data” or “new data”, or a combination of old and new data. Such a timing
should be avoided.
When the read address delay is between more than 71 and less than 599 or more than 583,680, read data will be
undetermined. However, normal write is achieved in this address condition.

PIN DESCRIPTION
Chip Select Mode (CSMODE)
This pin determines the polarity of the Chip Select (CS) pin. Always connect the CSMODE pin to VCC or VSS or
leave it open.
Chip Select (CS)
This pin enables or disables devices (RSTW, WE, IE, RSTR, RE, and OE). The polarity of the CS pin is dependent
upon the level of the CSMODE pin.
In case where the CSMODE pin is connected to VSS or left open:
When Chip Select (CS) is high, the device is enabled and ready for read/write operation. When Chip Select (CS) is
low, the device is disabled and the internal Write/Read Address Pointer stops. Writing in the device is suppressed.
The output of the pin goes to high impedance.
In case where the CSMODE pin is connected to VCC:
When Chip Select (CS) is low, the device is enabled and ready for read/write operation. When Chip Select (CS) is
high, the device is disabled and the internal Write/Read Address Pointer stops. Writing in the device is suppressed.
The output of the pin goes to high impedance.

The write/read operation is reset as follows:
In case where the CSMODE pin is connected to VSS or left open:
On the rising edge of SWCK, a write operation is reset when both RSTW and CS are high.
On the rising edge of SRCK, a read operation is reset when both RSTR and CS are high.
In case where the CSMODE pin is connected to VCC:
On the rising edge of SWCK, a write operation is reset when RSTW is high and CS is low.
On the rising edge of SRCK, a read operation is reset when RSTR is high and CS is low.
In this case, the CS setup time (tRWCSS/tRRCSS) and the CS hold time (tRWCSH/tRRCSH) must be satisfied relative to the
rising edge of SWCK/SRCK in the reset cycle.
When CS and CSMODE set the “Disabled” device state, the RSTW/RSTR input is invalid.
Satisfy the following conditions before causing CS to make a transition:
• Pull WE, IE, RE, and OE low respectively for times tWECSS, tIECSS, tRECSS, and tOECSS before causing CS to make a
transition.
• Enter five or more SWCK and SRCK cycles during times tWECSS, tIECSS, tRECSS, and tOECSS, and then cause CS to
make a transition. (A write operation requires five cycles or more of tWLCSA and tWLCSB. A read operation requires
five cycles or more of tRLCSA and tRLCSB.)
• Cause CS to make a transition only when RSTW and RSTR are low.
• Pull WE, IE, RE, and OE low respectively for times tWECSH, tIECSH, tRECSH, and tOECSH after causing CS to make a
transition.

disabled and FIFO2 is enabled. When CS makes a low-to-high transition after data of up to B7/D7 is written in or
read from FIFO2, FIFO2 is disabled and FIFO1 is enabled again. Data is written or read starting at A5/C5 in
FIFO1. (In the “Disabled” device state, the address pointer in the FIFO1 remains unchanged.)
CS Control Timing 2 (At Reset)
When RSTW or RSTR is input, write-reset or read-reset is applied only to FIFO2 since CS is low. (FIFO1 is not
reset.) Therefore, when FIFO1 is enabled again, data is written or read starting at Ai+5/Ci+5 in FIFO1.
CS Control Timing 3 (At Reset)
When RSTW or RSTR is input, write-reset or read-reset is applied only to FIFO1 (FIFO2 is not reset.) Therefore,
data is written or read starting at Bi/Di in FIFO2.
When FIFO1 is enabled again, data is written or read again starting at A0/C0 in FIFO1 since the internal address
pointer is already reset.
Power-up and Initialization
On power-up, the device is designed to begin proper operation after at least 200 µs after Vcc has stabilized to a
value within the range of recommended operating conditions. After this 200 µs stabilization interval, the following
initialization sequence must be performed. Because the read and write address pointers are undefined after
power-up, a minimum of 330 dummy write operations (SWCK cycles) and read operations (SRCK cycles) must be
performed, followed by an RSTW operation and an RSTR operation, to properly initialize the write and the read
address pointer.
