LY61L10248A
Rev. 1.1
1M X 8 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The LY61L10248A is a 8M-bit high speed CMOS
static random access memory organized as 1,024K
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 LY61L10248A operates from a single power
supply of 3.3V and all inputs and outputs are fully
TTL compatible

Single 3.3V 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 6mmx8mm TFBGA
