256K X 16 BIT HIGH SPEED CMOS SRAM
Rev. 2.3
FEATURES
GENERAL DESCRIPTION
The LY61L25616 is a 4,194,304-bit low power
CMOS static random access memory organized as
262,144 words by 16 bits. It is fabricated using very
high performance, high reliability CMOS technology.
Its standby current is stable within the range of
operating temperature.
Fast access time : 10/12/15/20/25ns
Very low power consumption:
Operating current:
180/160/140/80/70mA(MAX.)
Standby current:
12mA(MAX. for 10/12/15ns)
5mA(MAX. for 20/25ns)
The LY61L25616 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
100 A( (MAX. for 20/25ns LL version)
µ
Single 3.3V power supply
All inputs and outputs TTL compatible
Fully static operation
Tri-state output
Data byte control : LB# (DQ0 ~ DQ7)
UB# (DQ8 ~ DQ15)
The LY61L25616 operates from a single power
supply of 3.3V and all inputs and outputs are fully
TTL compatible
Data retention voltage : 2.0V (MIN.)
Green package available
Package : 44-pin 400 mil TSOP-II

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