Functional Description
CY7C1049G and CY7C1049GE are high-performance CMOS
fast static RAM devices with embedded ECC. Both devices are
offered in single and dual chip-enable options and in multiple pin
configurations. The CY7C1049GE device includes an ERR pin
that signals an error-detection and correction event during a read
cycle.
Data writes are performed by asserting the Chip Enable (CE) and
Write Enable (WE) inputs LOW, while providing the data on I/O0
through I/O7 and address on A0 through A18 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/O0 through I/O7).
All I/Os (I/O0 through I/O7) are placed in a high-impedance state
during the following events:
The device is deselected (CE HIGH)
The control signal OE is de-asserted
On the CY7C1049GE 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)[1]. See the Truth
Table on page 14 for a complete description of read and write
modes.
The logic block diagram is on page 2.

Notes
1. This device does not support automatic write-back on error detection.
2. The ERR pin is available only for devices which have ERR option “E” in the ordering code. Refer Ordering Information on page 15 for details.
3. Typical values are included only for reference and are not guaranteed or tested. Typical values are measured at VCC = 1.8 V (for a VCC range of 1.65 V–2.2 V),
VCC = 3 V (for a VCC range of 2.2 V–3.6 V), and VCC = 5 V (for a VCC range of 4.5 V–5.5 V), TA = 25 °C.
