CY7C1049DV33 4-Mbit (512 K 8) Static RAM 4-Mbit (512 K 8) Static RAM Features Functional Description Pin and function compatible with CY7C1049CV33 The CY7C1049DV33 is a high performance CMOS Static RAM organized as 512K words by 8-bits. Easy memory expansion is High speed provided by an Active LOW Chip Enable (CE), an Active LOW t = 10 ns AA Output Enable (OE), and tristate drivers. You can write to the device by taking Chip Enable (CE) and Write Enable (WE) inputs Low active power LOW. Data on the eight I/O pins (IO through IO ) is then written 0 7 I = 90 mA at 10 ns CC into the location specified on the address pins (A through A ). 0 18 Low CMOS standby power You can read from the device by taking Chip Enable (CE) and I = 10 mA SB2 Output Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under these conditions, the contents of the memory location 2.0 V data retention specified by the address pins appear on the I/O pins. Automatic power down when deselected The eight input or output pins (IO through IO ) are placed in a 0 7 high impedance state when the device is deselected (CE HIGH), TTL compatible inputs and outputs the outputs are disabled (OE HIGH), or during a write operation Easy memory expansion with CE and OE features (CE LOW, and WE LOW). Available in Pb-free 36-pin (400 Mil) molded SOJ and 44-pin The CY7C1049DV33 is available in standard 400 Mil wide 36 TSOP II packages -pin SOJ package and 44-pin TSOP II package with center power and ground (revolutionary) pinout.
