LY61L1288
Rev. 1.2
128K X 8 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The LY61L1288 is a 1,048,576-bit high speed
CMOS static random access memory organized as
131,072 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 LY61L1288 is well designed for high speed
system application. Easy expansion is provided by
using an active LOW Chip Enable(CE#). The active
LOW Write Enable(WE#) controls both writing and
reading of the memory.
The LY61L1288 operates from a single power
supply of 3.3V and all inputs and outputs are fully
TTL compatible
FEATURES
Fast access time : 8/10/12/15ns
Low power consumption:
Operating current : 80/75/70/65mA (TYP.)
Standby current : 0.6mA (TYP.)
Single 3.3V power supply
All inputs and outputs TTL compatible
Fully static operation
Tri-state output
Data retention voltage : 2.0V (MIN.)
Green package available
Package : 32-pin 8mm x 13.4mm STSOP
