The LY62W5128 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 LY62W5128 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY62W5128 operates from a single power
supply of 2.7V ~ 5.5V and all inputs and outputs are
fully TTL compatible

Notes:
1. VIH(max) = VCC + 3.0V for pulse width less than 10ns.
2. VIL(min) = VSS - 3.0V for pulse width less than 10ns.
3. Over/Undershoot specifications are characterized, not 100% tested.
4. Typical values are included for reference only and are not guaranteed or tested.
Typical values are measured at VCC = VCC(TYP.) and TA = 25℃
5. This parameter is measured at VCC = 3.0V

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.WE#, CE# must be high during all address transitions.
2.A write occurs during the overlap of a low CE#, low WE#.
3.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.
4.During this period, I/O pins are in the output state, and input signals must not be applied.
5.If the CE# low transition occurs simultaneously with or after WE# low transition, the outputs remain in a high impedance state.
6.tOW and tWHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
