Functional Description
CY7C1011G is a high-performance CMOS fast static RAM
automotive part with embedded ECC. This device has a single
Chip Enable (CE) input, and is accessed by asserting it LOW.
To perform data writes, assert the Write Enable (WE) input LOW,
and provide the data on the device data pins (I/O₀ through I/O₁₅)
and address pins (A₀ through A₁₆) pins. 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/O₈ through I/O₁₅ and BLE controls I/O₀
through I/O₇.
To perform data reads, assert the Output Enable (OE) input and
provide the required address on the address lines. You can
access read data on the I/O lines (I/O₀ through I/O₁₅). To perform
byte access, assert 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/O₀ through I/O₁₅) are placed in a high-impedance state
when the device is deselected (CE LOW), or when the control
signals are deasserted (OE, BLE, BHE).
