FEATURES
GENERAL DESCRIPTION
 Fast access time : 20ns
 Very low power consumption:
Operating current (Normal version):
50mA (TYP.)
Standby current:
0.5mA (TYP. for 20ns)
20µ A (TYP. for LL version)
 Single 3.3V power supply
 All inputs and outputs TTL compatible
 Fully static operation
 Tri-state output
 Data retention voltage : 2.0V (MIN.)
 Green package available
 Package : 44-pin 400 mil TSOP II
The LY61L5128 is a 4,194,304-bit low power CMOS
static random access memory organized as 524,288
words by 8 bits. It is fabricated using very high
performance, high reliability CMOS technology. Its
standby current is stable within the range of operating
temperature.
The LY61L5128 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY61L5128 operates from a single power
supply of 3.3V and all inputs and outputs are fully
TTL compatible

2.Device is continuously selected OE# = low, CE# = low.
3.Address must be valid prior to or coincident with CE# = low,; otherwise tAA is the limiting parameter.
4.tCLZ, tOLZ, tCHZ and tOHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
5.At any given temperature and voltage condition, tCHZ is less than tCLZ , tOHZ is less than tOLZ.

Notes :
1.A write occurs during the overlap of a low CE#, low WE#.
2.During a WE# controlled write cycle with OE# low, tWP must be greater than tWHZ + tDW to allow the drivers to turn off and data to be placed
on the bus.
3.During this period, I/O pins are in the output state, and input signals must not be applied.
4.If the CE# low transition occurs simultaneously with or after WE# low transition, the outputs remain in a high impedance state.
5.tOW and tWHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
