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).
