Functional Description
The CY7C1049CV33 is a high-performance CMOS Static
RAM organized as 524,288 words by 8 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/O
specified on the address pins (A
Reading from the device is accomplished by taking Chip
Enable (CE) and Output Enable (OE) LOW while forcing Write
Enable (WE) HIGH. Under these conditions, the contents of
the memory location specified by the address pins will appear
on the I/O pins.
The eight input/output pins (I/O
high-impedance state when the device is deselected (CE
HIGH), the outputs are disabled (OE HIGH), or during a Write
operation (CE LOW, and WE LOW).
The CY7C1049CV33 is available in standard 400-mil-wide
36-pin SOJ package and 44-pin TSOP II package with center
power and ground (revolutionary) pinout.
