Functional Description
The CY7C199D is a high performance CMOS static RAM
organized as 32,768 words by 8-bits. Easy memory expansion is
provided by an active LOW chip enable (CE), an active LOW
output enable (OE) and tri-state drivers. This device has an
automatic power-down feature, reducing the power consumption
when deselected. The input and output pins (I/O
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).
Write to the device by taking chip enable (CE) and write enable
(WE) inputs LOW. Data on the eight I/O pins (I/O
is then written into the location specified on the address pins (A
through A
Read from the device 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 appears on the I/O pins.
For best practice recommendations, refer to the Cypress
