1. GENERAL DESCRIPTION
W965L6ABN is a 32M bits CMOS pseudo static random access memory (Pseudo SRAM), organized
as 2M words x 16 bits. Using advanced single transistor DRAM architecture and 0.175 µm process
technology; W964L6BN delivers fast access cycle time and low power consumption. It is suitable for
mobile device application such as Cellular Phone and PDA, which high-density buffer is needed and
power dissipation is most concerned.
2. FEATURES

• Fast access cycle time:
tRC = 70 nS (-70), 80 nS (-80)
• Low power consumption:
IDDA1 = 25 mA max.
• Wide operating conditions:
VDD = +2.3V to +2.7V or
+2.7V to +3.3V
• Temperature
TA = 0°C to +70°C
TA = -25°C to +85°C (Extended temperature)
TA = -40°C to +85°C (Industrial temperature)

WARNING: Recommended operating conditions are normal operating ranges for the semiconductor device. All
the device’s electrical characteristics are warranted when operated within these ranges.
Always use semiconductor devices within the recommended operating conditions. Operation outside
these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the datasheet. Users considering application outside the listed conditions are advised to contact their
Winbond representative beforehand.

Notes:
*1: The output load is 50 pF at VDD (27) and 30pF at VDD (23).
*2: The output load is 5 pF.
*3: The tCE is applicable if OE is brought to Low before CE1 goes Low and is also applicable if actual value of both or
either tASO or tCLOL is shorter than specified value.
*4: Applicable if OE is brought to Low before CE1 goes Low.
*5: The tASO, tCLOL(min.) and tOP(min.) are reference values when the access time is determined by tOE. If actual value of
each parameter is shorter than specified minimum value, tOE become longer by the amount of subtracting actual
value from specified minimum value.
For example, if actual tASO, tASO(actual), is shorter than specified minimum value, tASO(min.), during OE control
access (ie., CE1 stays Low), the tOE become tOE(max) + tASO(min.) - tASO(actual).
*6: The tASO[ABS] and tOP[ABS] is the absolute minimum value during OE control access.
*7: If actual value of either tCLOL or tOP is shorter than specified minimum value, both tOLAH and tOLCH become tRC(min.) -
tCLOL(actual) or tRC(min) - tOP(actual).
*8: Maximum value is applicable if CE1 is kept at low.

Write Operation, Continued
Notes:
*1: Minimum value must be equal or greater than the sum of actual tCW (or tWP) and tWRC (or tWR).
*2: New write address is valid from either CE1 or WE is brought to High.
*3: The tOEH is specified from end of tWC(min.). The tOEH(min.) is a reference value when the access time is determined
by tOE.
If actual value, tOEH(actual) is shorter than specified minimum value, tOE become longer by the amount of subtracting
actual value from specified minimum value.
*4: The tOEH(max.) is applicable if CE1 is kept at Low and both WE and OE are kept at High.
*5: The tOEH[ABS] is the absolute minimum value if write cycle is terminated by WE and CE1 stays Low.
*6: tOHCL(min.) must be satisfied if read operation is not performed prior to write operation.
In case OE is disabled after tOHCL(min.), WE Low must be asserted after tRC(min.) from CE1 Low. In other
words, read operation is initiated if tOHCL(min.) is not satisfied.
*7: Applicable if CE1 stays Low after read operation.
*8: tCW and tWP is applicable if write operation is initiated by CE1 and WE , respectively.
*9: tWRC and tWR is applicable if write operation is terminated by CE1 and WE , respectively.
The tWR(min.) can be ignored if CE1 is brought to High together or after WE is brought to High. In such case, the
tCP(min.) must be satisfied.
