Functional Description
CY7C1049GN is a high-performance CMOS fast static RAM
device organized as 512K words by 8-bits.
Data writes are performed by asserting the Chip Enable (CE) and
Write Enable (WE) inputs LOW, while providing the data on I/O
0
through I/O
7
and address on A
0
through A
18
pins.
Data reads are performed by asserting the Chip Enable (CE) and
Output Enable (OE) inputs LOW and providing the required
address on the address lines. Read data is accessible on the I/O
lines (I/O
0
through I/O
7
).
All I/Os (I/O
0
through I/O
7
) are placed in a high-impedance state
during the following events:
■

t
AA

Low active and standby currents
❐
Active current: I
CC
= 38 mA typical
❐
Standby current: I
SB2
= 6 mA typical
Operating voltage range: 1.65 V to 2.2 V, 2.2 V to 3.6 V, and
4.5 V to 5.5 V
1.0 V data retention
TTL-compatible inputs and outputs
Pb-free 36-pin SOJ and 44-pin TSOP II packages
