CY7C1049GN 4-Mbit (512K words 8-bit) Static RAM 4-Mbit (512K words 8-bit) Static RAM Features Functional Description High speed CY7C1049GN is a high-performance CMOS fast static RAM device organized as 512K words by 8-bits. t = 10 ns AA Data writes are performed by asserting the Chip Enable (CE) and Low active and standby currents Write Enable (WE) inputs LOW, while providing the data on I/O 0 Active current: I = 38 mA typical CC through I/O and address on A through A pins. 7 0 18 Standby current: I = 6 mA typical SB2 Data reads are performed by asserting the Chip Enable (CE) and Operating voltage range: 1.65 V to 2.2 V, 2.2 V to 3.6 V, and Output Enable (OE) inputs LOW and providing the required 4.5 V to 5.5 V address on the address lines. Read data is accessible on the I/O lines (I/O through I/O ). 0 7 1.0 V data retention All I/Os (I/O through I/O ) are placed in a high-impedance state 0 7 TTL-compatible inputs and outputs during the following events: Pb-free 36-pin SOJ and 44-pin TSOP II packages The device is deselected (CE HIGH) The control signal OE is de-asserted The logic block diagram is on page 2.
