2-Mbit (128K words × 16 bit) Static RAM  
with Error-Correcting Code (ECC)  
2-Mbit (128K words  
× 16 bit) Static RAM with Error-Correcting Code (ECC)  
Features  
Functional Description  
CY7C1011G is a high-performance CMOS fast static RAM  
automotive part with embedded ECC. This device has a single  
Chip Enable (CE) input, and is accessed by asserting it LOW.  
High speed  
tAA = 10 ns  
Temperature range  
Automotive-A: –40 °C to 85 °C  
Automotive-E: –40 °C to 125 °C  
To perform data writes, assert the Write Enable (WE) input LOW,  
and provide the data on the device data pins (I/O0 through I/O15  
)
and address pins (A0 through A16) pins. The Byte High Enable  
(BHE) and Byte Low Enable (BLE) inputs control byte writes and  
write data on the corresponding I/O lines to the memory location  
specified. BHE controls I/O8 through I/O15 and BLE controls I/O0  
through I/O7.  
Embedded error-correcting code (ECC) for single-bit error  
correction[1]  
Low active and standby current  
Active current, ICC = 40-mA typical (Automotive-E)  
Standby current, ISB2 = 6-mA typical (Automotive-E)  
To perform data reads, assert the Output Enable (OE) input and  
provide the required address on the address lines. You can  
access read data on the I/O lines (I/O0 through I/O15). To perform  
byte access, assert 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.  
Operating voltage range: 2.2 V to 3.6 V  
1.0-V data retention  
TTL compatible inputs and outputs  
Available in Pb-free 48-ball VFBGA and 44-pin TSOP II  
All I/Os (I/O0 through I/O15) are placed in a high-impedance state  
when the device is deselected (CE LOW), or when the control  
signals are deasserted (OE, BLE, BHE).
