FEATURES
GENERAL DESCRIPTION
„ Fast access time : 55/70ns
„ Low power consumption:
Operating current : 45/30mA (TYP.)
Standby current : 8μA (TYP.) LL-version
„ Single 4.5V ~ 5.5V power supply
„ All inputs and outputs TTL compatible
„ Fully static operation
„ Tri-state output
„ Data retention voltage : 1.5V (MIN.)
„ Green package available
„ Package : 44-pin 400 mil TSOP-II
48-ball 6mm x 8mm TFBGA
The LY6210248 is a 8,388,608-bit low power CMOS
static random access memory organized as
1,048,576 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 LY6210248 is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The LY6210248 operates from a single power
supply of 4.5V ~ 5.5V and all inputs and outputs are
fully TTL compatible

2.Device is continuously selected OE# = low, CE# = low., CE2 = high.
3.Address must be valid prior to or coincident with CE# = low, CE2 = high; 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.WE#, CE# 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#.
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 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.
