There are three chip enable pins (CE1, CE2, CE2) that allow the
user to deselect the device when desired. If any one of these three are not
asserted when ADV/LDis low, no new memory operation can be initiated.

Address Inputs
I
N/A
Synchronous Address inputs. The address register is triggered by a combination of the
rising edge of CLK, ADV/LD low, CEN low, and true chip enables.
ADV/LD
Advance / Load
I
N/A
ADV/LD is a synchronous input that is used to load the internal registers with new address
and control when it is sampled low at the rising edge of clock with the chip selected. When
ADV/LD is low with the chip deselected, any burst in progress is terminated. When ADV/LD
is sampled high then the internal burst counter is advanced for any burst that was in
progress. The external addresses are ignored when ADV/LD is sampled high.
R/W
Read / Write
Clock Enable
I
I
N/A
R/W signal is a synchronous input that identifies whether the current load cycle initiated is a
Read or Write access to the memory array. The data bus activity for the current cycle takes
place two clock cycles later.
LOW
Synchronous Clock Enable Input. When CEN is sampled high, all other synchronous
inputs, including clock are ignored and outputs remain unchanged. The effect of CEN
sampled high on the device outputs is as if the low to high clock transition did not occur.
For normal operation, CEN must be sampled low at rising edge of clock.

On load write cycles (When R/W and ADV/LD are sampled low) the appropriate byte write
signal (BW1-BW4) must be valid. The byte write signal must also be valid on each cycle of
a burst write. Byte Write signals are ignored when R/W is sampled high. The appropriate
byte(s) of data are written into the device two cycles later. BW -BW can all be tied low if
always doing write to the entire 36-bit word.

When OE is high the I/O pins are in a high-impedance state. OE does not need to be
actively controlled for read and write cycles. In normal operation, OE can be tied low.

Asynchronous sleep mode input. ZZ HIGH will gate the CLK internally and power down

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated
in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. VDD terminals only.
3. VDDQ terminals only.
4. Input terminals only.
5. I/O terminals only.
6. This is a steady-state DC parameter that applies after the power supply has
reached its nominal operating value. Power sequencing is not necessary;
however, the voltage on any input or I/O pin cannot exceed VDDQ during power
supply ramp up.

NOTES:
1. L = VIL, H = VIH, X = Don’t Care.
2. When ADV/LD signal is sampled high, the internal burst counter is incremented. The R/W signal is ignored when the counter is advanced. Therefore the nature of
the burst cycle (Read or Write) is determined by the status of the R/W signal when the first address is loaded at the beginning of the burst cycle.
3. Deselect cycle is initiated when either (CE1, or CE2 is sampled high or CE2 is sampled low) and ADV/LD is sampled low at rising edge of clock. The data bus will
tri-state two cycles after deselect is initiated.
4. When CEN is sampled high at the rising edge of clock, that clock edge is blocked from propogating through the part. The state of all the internal registers and the I/
Os remains unchanged.
5. To select the chip requires CE1 = L, CE2 = L, CE2 = H on these chip enables. Chip is deselected if any one of the chip enables is false.
6. Device Outputs are ensured to be in High-Z after the first rising edge of clock upon power-up.
7. Q - Data read from the device, D - data written to the device.

NOTES:

1. tF = 1/tCYC.
2. Measured as HIGH above 0.6VDDQ and LOW below 0.4VDDQ.
3. Transition is measured ±200mV from steady-state.
4. These parameters are guaranteed with the AC load (Figure 1) by device characterization. They are not production tested.
5. To avoid bus contention, the output buffers are designed such that tCHZ (device turn-off) is about 1ns faster than tCLZ (device turn-on) at a given temperature and voltage.
The specs as shown do not imply bus contention because tCLZ is a Min. parameter that is worse case at totally different test conditions (0 deg. C, 3.465V) than tCHZ,
which is a Max. parameter (worse case at 70 deg. C, 3.135V).

NOTES:
1. D (A1) represents the first input to the external address A1. D (A2) represents the first input to the external address A2; D (A2+1) represents the next input data in the burst sequence of
the base address A2, etc. where address bits A0 and A1 are advancing for the four word burst in the sequence defined by the state of the LBO input.
2. CE2 timing transitions are identical but inverted to the CE1 and CE2 signals. For example, when CE1 and CE2 are LOW on this waveform, CE2 is HIGH.
3. Burst ends when new address and control are loaded into the SRAM by sampling ADV/LD LOW.
4. R/W is don't care when the SRAM is bursting (ADV/LD sampled HIGH). The nature of the burst access (Read or Write) is fixed by the state of the R/W signal when new address
and control are loaded into the SRAM.
5. Individual Byte Write signals (BWx) must be valid on all write and burst-write cycles. A write cycle is initiated when R/W signal is sampled LOW. The byte write information comes in two
cycles before the actual data is presented to the SRAM.

NOTES:
1. Q (A1) represents the first output from the external address A1. D (A2) represents the input data to the SRAM corresponding to address A2.
2. CE2 timing transitions are identical but inverted to the CE1 and CE2 signals. For example, when CE1 and CE2 are LOW on this waveform, CE2 is HIGH.
3. CEN when sampled high on the rising edge of clock will block that L-H transition of the clock from propogating into the SRAM. The part will behave as if the L-H clock transition did not
occur. All internal registers in the SRAM will retain their previous state.
4. Individual Byte Write signals (BWx) must be valid on all write and burst-write cycles. A write cycle is initiated when R/W signal is sampled LOW. The byte write information comes in two
cycles before the actual data is presented to the SRAM.
