HY62UF16400A/ HY62QF16400A/ HY62EF16400A/
HY62SF16400A Series
256Kx16bit full CMOS SRAM
PRELIMINARY
DESCRIPTION
The HY62UF16400A / HY62QF16400A /
HY62EF16400A / HY62SF16400A is a high
speed, super low power and 4Mbit full CMOS
SRAM organized as 262,144 words by 16bits. The
HY62UF16400A
/
HY62QF16400A
/
HY62EF16400A / HY62SF16400A 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

2. UB, LB(Upper, Lower Byte enable)
These active LOW inputs allow individual bytes to be written or read.
When LB is LOW, data is written or read to the lower byte, I/O 1 -I/O 8.
When UB is LOW, data is written or read to the upper byte, I/O 9 -I/O 16.
