Functional Description
The CY7C1061DV33 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
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).
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 11
for a complete description of Read and Write modes.
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).
The CY7C1061DV33 is available in a 54-pin TSOP II package
with center power and ground (revolutionary) pinout, and 48-ball
VFBGA packages.
