HY62UF8400A/ HY62QF8400A/ HY62EF8400A/
HY62SF8400A Series
512Kx8bit full CMOS SRAM
PRELIMINARY
DESCRIPTION
The
HY62UF8400A
/
HY62QF8400A
/
HY62EF8400A / HY62SF8400A is a high speed
and super low power 4Mbit full CMOS SRAM
organized as 524,288 words by 8 bits. The
HY62UF8400A / HY62QF8400A / HY62EF8400A
/ HY62SF8400A uses high performance full
CMOS process technology and is designed for
high speed and low power circuit technology. It is
particularly well-suited for the high density low
power system application. This device has a data
retention mode that guarantees data to remain
valid at a minimum power supply voltage of 1.5V.
FEATURES
•
Fully static operation and Tri-state output
•
TTL compatible inputs and outputs
•
Battery backup(LL/SL-part)
- 1.5V(min) data retention
•
Standard pin configuration
- 48ball uBGA
