Functional Description
The CY7C1069AV33 is a high performance complementary
metal oxide semiconductor (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 WE HIGH. See “Truth Table” on
page 8 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.
