Functional Description

The CY7C1049CV33 is a high performance Complementary metal oxide semiconductor (CMOS) Static RAM organized as 524,288 words by eight bits. Easy memory expansion is provided by an active LOW Chip Enable (CE), an active LOW Output Enable (OE), and three-state drivers. Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A18).
