AS7C316098A
Rev. 1.2
1024K X 16 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The AS7C316098A is a 16M-bit high speed CMOS
static random access memory organized as 1024K
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.
The AS7C316098A operates from a single
power supply of 3.3V and all inputs and outputs are
fully TTL compatible
FEATURES
• Fast access time : 10ns
•
low power consumption:
Operating current:
90mA (typical)
Standby current:
4mA(Typical)
• 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)
• Data retention voltage : 1.5V (MIN.)
•
Green package available
• Package : 48-pin 12mm x 20mm TSOP-I
48-ball 6mmx8mm TFBGA
