CY62158H MoBL 8-Mbit (1M words 8-bit) Static RAM with Error-Correcting Code (ECC) 8-Mbit (1M words 8-bit) Static RAM with Error-Correcting Code (ECC) Features Functional Description Ultra-low standby power CY62158H is a high-performance CMOS low-power (MoBL) SRAM device with embedded ECC. Typical standby current: 5.5 A Maximum standby current: 16 A Device is accessed by asserting both chip enable inputs CE 1 as LOW and CE as HIGH. 2 High speed: 45 ns Write to the device is performed by taking Chip Enable 1 (CE ) 1 Embedded error-correcting code (ECC) for single-bit error LOW and Chip Enable 2 (CE ) HIGH and the Write Enable (WE) 2 1, 2 correction input LOW. Data on the eight I/O pins (I/O through I/O ) is then 0 7 written into the location specified on the address pins (A through 0 Operating voltage range: 4.5 V to 5.5 V A ). 19 1.0-V data retention Read from the device is performed by taking Chip Enable 1 (CE ) 1 Transistor-transistor logic (TTL) compatible inputs and outputs and Output Enable (OE) LOW and Chip Enable 2 (CE ) HIGH 2 while forcing Write Enable (WE) HIGH. Under these conditions, Available in Pb-free 44-pin TSOP II package the contents of the memory location specified by the address pins will appear on the I/O pins. The eight input and output pins (I/O through I/O ) are placed in 0 7 a high-impedance state when the device is deselected (CE 1 HIGH or CE LOW), the outputs are disabled (OE HIGH), or a 2 write operation is in progress (CE LOW and CE HIGH and WE 1 2 LOW). See the Truth Table CY62158H on page 11 for a complete description of read and write modes.
