The LY62L205016A is a 33,554,432-bit low power
CMOS static random access memory organized as
2,097,152 words by 16 bits or 4,194,304 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 LY62L205016A is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY62L205016A operates from a single
power supply of 2.7V ~ 3.6V and all inputs and
outputs are fully TTL compatible

Notes :
1.WE#,CE#, LB#, UB# must be high or CE2 must be low during all address transitions.
2.A write occurs during the overlap of a low CE#, high CE2, low WE#, LB# or UB# = low.
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#, LB#, UB# low transition and CE2 high 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.
