Functional Description
The CY7C1051DV33 is a high performance CMOS Static RAM organized as 512 K words by 16-bits. To write to the device, take Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte LOW Enable (BLE) is LOW, then data from I/O pins (I/O0–I/O7), is written into the location specified on the address pins (A0–A18). If Byte HIGH Enable (BHE) is LOW, then data from I/O pins (I/O8–I/O15) is written into the location specified on the address pins (A0–A18). To read from the device, take Chip Enable (CE) 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 appears on I/O0–I/O7. If Byte HIGH Enable (BHE) is LOW, then data from memory appears on I/O8 to I/O15. See the Truth Table on page 10 for a complete description of read and write modes. The input/output pins (I/O0–I/O15) are placed in a high-impedance state when the device is de...
