Functional Description
The CY7C1046D is a high-performance CMOS static RAM
organized as 1M words by 4 bits. Easy memory expansion is
provided by an active LOW Chip Enable (CE), an active LOW
Output Enable (OE), and tri-state drivers. Writing to the device is
accomplished by taking Chip Enable (CE) and Write Enable
(WE) inputs LOW. Data on the four I/O pins (I/O0 through I/O3)
is then written into the location specified on the address pins (A0
through A19).
Reading from the device is accomplished by taking Chip Enable
(CE) and Output Enable (OE) LOW while forcing Write Enable
(WE) HIGH. Under these conditions, the contents of the memory
location specified by the address pins will appear on the I/O pins.
The four input/output pins (I/O0 through I/O3) are placed in a
high-impedance state when the device is deselected (CE HIGH),
the outputs are disabled (OE HIGH), or during a write operation
(CE LOW, and WE LOW).
The CY7C1046D is available in a standard 400-mil-wide 32-pin
SOJ package with center power and ground (revolutionary)
pinout.
The CY7C1046D device is suitable for interfacing with
processors that have TTL I/P levels. It is not suitable for
processors that require CMOS I/P levels. Please see Electrical
Characteristics on page 4 for more details and suggested
alternatives.
