Transistor-transistor logic (TTL) compatible inputs and outputs

To access devices with a single chip enable input, assert the chip
enable (CE) input LOW. To access dual chip enable devices,
assert both chip enable inputs – CE
1
as LOW and CE
2
as HIGH.
To perform data writes, assert the Write Enable (WE) input LOW,
and provide the data and address on the device data pins (I/O
0
through I/O
15
) and address pins (A
0
through A
19
) respectively.
The Byte High Enable (BHE) and Byte Low Enable (BLE) inputs
control byte writes, and write data on the corresponding I/O lines
to the memory location specified. BHE controls I/O
8
through
I/O
15
and BLE controls I/O
0
through I/O
7
.
To perform data reads, assert the Output Enable (OE) input and
provide the required address on the address lines. Read data is
accessible on I/O lines (I/O
0
through I/O
15
). You can perform
byte accesses by asserting the required byte enable signal (BHE
or BLE) to read either the upper byte or the lower byte of data
from the specified address location.
All I/Os (I/O
0
through I/O
15
) are placed in a high-impedance state
when the device is deselected (CE HIGH for a single chip enable
device and CE
1
HIGH / CE
2
LOW for a dual chip enable device),
or control signals are de-asserted (OE, BLE, BHE).
On the CY7C1061GE devices, the detection and correction of a
single-bit error in the accessed location is indicated by the
assertion of the ERR output (ERR = High). See the
Truth Table
on page 16
for a complete description of read and write modes.
The logic block diagrams are on page 2.
The CY7C1061G and CY7C1061GE devices are available in
48-pin TSOP I, 54-pin TSOP II, and 48-ball VFBGA packages.

Functional Description
CY7C1061G and CY7C1061GE are high-performance CMOS
fast static RAM devices with embedded ECC
[1]
. Both devices are
offered in single and dual chip enable options and in multiple pin
configurations. The CY7C1061GE device includes an ERR pin
that signals a single-bit error-detection and correction event
during a read cycle.
