Hyundai Semiconductor
HY62256A Series
32Kx8bit CMOS SRAM
DESCRIPTION
The HY62256A is a high-speed, low power and
32,786 x 8-bits CMOS Static Random Access
Memory
fabricated
using
Hyundai's
high
performance CMOS process technology. The
HY62256A has a data retention mode that
guarantees data to remain valid at the minimum
power supply voltage of 2.0 volt. Using the CMOS
technology, supply voltages from 2.0 to 5.5volt
has little effect on supply current in the data
retention mode. The HY62256A is suitable for use
in low voltage operation and battery back-up
application.
FEATURES
Fully static operation and Tri-state output
TTL compatible inputs and outputs
Low power consumption
Battery backup(L/LL-part)
- 2.0V(min.) data retention
Standard pin configuration
- 28 pin 600 mil PDIP
- 28 pin 330mil SOP
- 28 pin 8x13.4 mm TSOP-I
(Standard and Reversed)
