Functional Description
The CY7C1051DV33 is a high performance CMOS Static RAM
organized as 512 K words by 16-bits.
To write to the device, take Chip Enable (CE) and Write Enable
(WE) inputs LOW. If Byte LOW Enable (BLE) is LOW, then data
from I/O pins (I/O0–I/O7), is written into the location specified on
the address pins (A0–A18). If Byte HIGH Enable (BHE) is LOW,
then data from I/O pins (I/O8–I/O15) is written into the location
specified on the address pins (A0–A18).
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–I/O7. If
Byte HIGH Enable (BHE) is LOW, then data from memory
appears on I/O8 to I/O15. See the Truth Table on page 10 for a
complete description of read and write modes.
The input/output pins (I/O0–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 a write operation (CE LOW, and
WE LOW) is in progress.
The CY7C1051DV33 is available in a 44-pin TSOP II package
with center power and ground (revolutionary) pinout and a
48-ball FBGA package.
