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.  
Data writes are performed by asserting the Write Enable (WE)  
input LOW, while providing the data on I/O0 through I/O7 and  
address on A0 through A18 pins.  
Features  
High speed: 45 ns/55 ns  
Ultra-low standby power  
Data reads are performed by asserting the Output Enable (OE)  
input and providing the required address on the address lines.  
Read data is accessible on the I/O lines (I/O0 through I/O7).  
Typical standby current: 3.5 A  
Maximum standby current: 8.7 A  
Embedded ECC for single-bit error correction[1]  
All I/Os (I/O0 through I/O7) are placed in a HI-Z state when the  
device is deselected (CE HIGH or control signal OE is  
de-asserted).  
Wide voltage range: 1.65V to 2.2 V, 2.2 V to 3.6 V, 4.5 V to 5.5 V  
1.0-V data retention  
See the Truth Table – CY62148G on page 12 for a complete  
description of read and write modes.  
TTL-compatible inputs and outputs  
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)  
SRAM device with embedded ECC[1]. This device is offered  
multiple pin configurations.
