Infineon SRAM Memory Chip, CY7C1049GN-10VXI- 4Mbit

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/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.
