HY62LF16804A Datasheet, PDF (2/10 Pages) Nel Frequency Controls,inc – 512Kx16bit full CMOS SRAM

HY62LF16804A Series
DESCRIPTION
The HY62LF16804A is a high speed, super low
power and 8Mbit full CMOS SRAM organized as
524,288 words by 16bits. The HY62LF16804A
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.
FEATURES
• Fully static operation and Tri-state output
• TTL compatible inputs and outputs
• Battery backup(LL/SL-part)
- 1.2V(min) data retention
• Standard pin configuration
- 48-uBGA
