CY62148G MoBL 4-Mbit (512K words 8 bit) Static RAM with Error-Correcting Code (ECC) 4-Mbit (512K words 8 bit) Static RAM with Error-Correcting Code (ECC) Device is accessed by asserting the chip enable (CE) input LOW. Features Data writes are performed by asserting the Write Enable (WE) High speed: 45 ns/55 ns input LOW, while providing the data on I/O through I/O and 0 7 address on A through A pins. 0 18 Ultra-low standby power Data reads are performed by asserting the Output Enable (OE) Typical standby current: 3.5 A input and providing the required address on the address lines. Maximum standby current: 8.7 A Read data is accessible on the I/O lines (I/O through I/O ). 1 0 7 Embedded ECC for single-bit error correction All I/Os (I/O through I/O ) are placed in a HI-Z state when the 0 7 Wide voltage range: 1.65 V to 2.2 V, 2.2 V to 3.6 V, 4.5 V to 5.5 V device is deselected (CE HIGH or control signal OE is 1.0-V data retention de-asserted). See the Truth Table CY62148G on page 12 for a complete TTL-compatible inputs and outputs description of read and write modes. Pb-free 32-pin SOIC and 32-pin TSOP II packages The logic block diagrams are on page 2. Functional Description CY62148G is a high-performance CMOS low-power (MoBL) 1 SRAM device with embedded ECC . This device is offered multiple pin configurations.
