Functional Description
■ High speed
❐ tAA = 10 ns/15 ns
The CY7C1061GN/CY7C10612GN is a high performance
CMOS Static RAM organized as 1,048,576 words by 16 bits.
To write to the device, take Chip Enables (CE1 LOW and CE2
HIGH) 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
■ Low active power
❐ ICC = 90 mA at 100 MHz

A
19). 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).
■ Operating voltages of 2.2 V to 3.6 V
■ 1.0 V data retention
To read from the device, take Chip Enables (CE1 LOW and CE2
HIGH) 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 13
for a complete description of Read and Write modes.
■ Automatic power down when deselected
■ TTL compatible inputs and outputs
■ Easy memory expansion with CE1 and CE2 features
■ Available in Pb-free 48-pin TSOP I, 54-pin TSOP II, and 48-ball
VFBGA packages
The input or output pins (I/O0 through I/O15) are placed in a high
impedance state when the device is deselected (CE1 HIGH/CE2
LOW), the outputs are disabled (OE HIGH), the BHE and BLE
are disabled (BHE, BLE HIGH), or during a write operation (CE1
LOW, CE2 HIGH, and WE LOW).
■ Offered in dual Chip Enable options
