with Error-Correcting Code (ECC)  
4-Mbit (256K words  
× 16 bit) Static RAM with Error-Correcting Code (ECC)  
devices are accessed by asserting both chip enable inputs – CE1  
as low and CE2 as HIGH.  
Features  
■ High speed: 45 ns/55 ns  
Data writes are performed by asserting the Write Enable (WE)  
input LOW, while providing the data on I/O0 through I/O15 and  
address on A0 through A17 pins. The Byte High Enable (BHE)  
and Byte Low Enable (BLE) inputs control write operations to the  
upper and lower bytes of the specified memory location. BHE  
controls I/O8 through I/O15 and BLE controls I/O0 through I/O7.  
■ Ultra-low standby power  
❐ Typical standby current: 3.5 A  
❐ Maximum standby current: 8.7 A  
■ Embedded ECC for single-bit error correction[1]  
■ Widevoltage range: 1.65 V to2.2 V, 2.2 V to 3.6 V, 4.5 V to 5.5 V  
■ 1.0-V data retention  
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/O15).  
Byte accesses can be performed by asserting the required byte  
enable signal (BHE or BLE) to read either the upper byte or the  
lower byte of data from the specified address location.  
■ TTL-compatible inputs and outputs  
■ Error indication (ERR) pin to indicate 1-bit error detection and  
correction  
■ Pb-free 48-ball VFBGA and 44-pin TSOP II packages  
All I/Os (I/O0 through I/O15) are placed in a HI-Z state when the  
device is deselected (CE HIGH for a single chip enable device  
and CE1 HIGH/CE2 LOW for a dual chip enable device), or  
control signals are deasserted (OE, BLE, BHE).  
Functional Description  
CY62146G/CY62146GE and CY62146GSL/CY62146GESL are  
high-performance CMOS low-power (MoBL) SRAM devices with  
embedded ECC. Both devices are offered in single and dual chip  
enable options and in multiple pin configurations. The  
CY62146GE/CY62146GESL device includes an ERR pin that  
signals an error-detection and correction event during a read  
cycle. The CY62146GSL/CY62146GESL[1] device supports a  
wide voltage range of 2.2 V–3.6 V and 4.5 V–5.5 V.  
On the CY62146GE/CY62146GESL devices, the detection and  
correction of a single-bit error in the accessed location is  
indicated by the assertion of the ERR output (ERR = HIGH)[2]  
.
