Functional Description
The CY7C1069DV33 is a high-performance CMOS Static
RAM organized as 2,097,152 words by 8 bits. Writing to the
device is accomplished by enabling the chip (by taking CE₁
LOW and CE₂ HIGH) and Write Enable (WE) inputs LOW.
Reading from the device is accomplished by enabling the chip
(CE₁ LOW and CE₂ HIGH) as well as forcing the Output
Enable (OE) LOW while forcing the Write Enable (WE) HIGH.
See the truth table at the back of this data sheet for a complete
description of Read and Write modes.
The input/output pins (I/O₀ through I/O₇) are placed in a
high-impedance state when the device is deselected (CE₁
HIGH or CE₂ LOW), the outputs are disabled (OE HIGH), or
during a Write operation (CE₁ LOW, CE₂ HIGH, and WE
LOW).
The CY7C1069DV33 is available in a 54-pin TSOP II package
with center power and ground (revolutionary) pinout, and a
48-ball very fine-pitch ball grid array (VFBGA) package.
