Functional Description
The CY7C1069AV33 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 CY7C1069AV33 is available in a 54-pin TSOP II package
with center power and ground (revolutionary) pinout, and a
48-ball fine-pitch ball grid array (FBGA) package.
