Features
Functional Description
■ High speed
❐ tAA = 10 ns
The CY7C10612G and CY7C10612GE are high performance
CMOS fast static RAM devices with embedded ECC. These
devices are offered in single chip enable option. The
CY7C10612GE device includes an error indication pin that
signals an error-detection and correction event during a read
cycle.
■ Embedded error-correcting code (ECC) for single-bit error
correction
■ Low active power
❐ ICC = 90 mA typical
To write to the device, take Chip Enables (CE) and Write Enable
(WE) input LOW. If Byte Low Enable (BLE) is LOW, then data
from I/O pins (I/O0 through I/O7), is written into the location
specified on the address pins (A0 through A19). If Byte High
Enable (BHE) is LOW, then data from I/O pins (I/O8 through
I/O15) is written into the location specified on the address pins
(A0 through A19).
■ Low CMOS standby power
❐ ISB2 = 20 mA typical
■ Operating voltages of 3.3 ± 0.3 V
■ 1.0 V data retention
To read from the device, take Chip Enable (CE) and Output
Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If
Byte Low Enable (BLE) is LOW, then data from the memory
location specified by the address pins appears on I/O0 to I/O7. If
Byte High Enable (BHE) is LOW, then data from memory
appears on I/O8 to I/O15. See Truth Table on page 14 for a
complete description of Read and Write modes.
■ Transistor-transistor logic (TTL) compatible inputs and outputs
■ ERR pin to indicate 1-bit error detection and correction
■ Available in Pb-free 54-pin TSOP II package
The input or output pins (I/O0 through I/O15) are placed in a high
impedance state when the device is deselected (CE HIGH), the
outputs are disabled (OE HIGH), the BHE and BLE are disabled
(BHE, BLE HIGH), or during a write operation (CE LOW and WE
LOW).
On the CY7C10612GE 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). See the Truth Table
on page 14 for a complete description of read and write modes.
The CY7C10612G and CY7C10612GE are available in a 54-pin
TSOP II package.
