The LY62L102616A is a 16,777,216-bit low power
CMOS static random access memory organized as
1,048,576 words by 16 bits or 2,097,152 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 LY62L102616A is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY62L102616A operates from a single
power supply of 2.7V ~ 3.6V and all inputs and
outputs are fully TTL compatible

Notes:
1. VIH(max) = VCC + 2.0V for pulse width less than 6ns.
2. VIL(min) = VSS - 2.0V for pulse width less than 6ns.
3. Over/Undershoot specifications are characterized on engineering evaluation stage, not for mass production test.
4. Typical values are included for reference only and are not guaranteed or tested.
Typical valued are measured at VCC = VCC(TYP.) and TA = 25℃
5. This parameter is measured at VCC = 3.0V

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.
