HY62UF16803A Series
512Kx16bit full CMOS SRAM
Preliminary
DESCRIPTION
The HY62UF16803A is a high speed, super low
power and 8Mbit full CMOS SRAM organized as
524,288 words by 16bits. The HY62UF16803A
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 1.2V.

Note
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent
damage to the device. This is stress rating only and the functional operation of the device under these or
any other conditions above those indicated in the operation of this specification is not implied.
Exposure to the absolute maximum rating conditions for extended period may affect reliability.

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/O1 -I/O8.
When UB is LOW, data is written or read to the upper byte, I/O9 -I/O16.
