Functional Description
[1]
The CYK001M16SCCAU is a high-performance CMOS
pseudo static RAMs (PSRAM) organized as 1 Mb words by 16
bits that supports an asynchronous memory interface. This
device features advanced circuit design to provide ultra-low
active current. This is ideal for providing More Battery Life
(MoBL) in portable applications such as cellular telephones.
The device can be put into standby mode reducing power
consumption by more than 99% when deselected using CE
LOW, CE
2
HIGH or both BHE and BLE are HIGH. The
input/output pins (I/O
0
through I/O
15
) are placed in a
high-impedance state when: deselected (CE HIGH, CE
2
LOW
OE is deasserted HIGH), or during a write operation (Chip
Enabled and Write Enable WE LOW). The device also has an
automatic power-down feature that significantly reduces
power consumption by 99% when addresses are not toggling
even when the chip is selected (Chip Enable CE LOW, CE
2
HIGH and both BHE and BLE are LOW). Reading from the
device is accomplished by asserting the Chip Enables (CE
LOW and CE
2
HIGH) and Output Enable (OE) LOW while
forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE)
is LOW, then data from the memory location specified by the
address pins will appear on I/O
0
to I/O
7
. If Byte High Enable
(BHE) is LOW, then data from memory will appear on I/O
8
to
I/O
15
. See the Truth Table for a complete description of read
and write modes.
