Functional Description
[1]
The CY7C1399BN is a high-performance 3.3V CMOS Static
RAM organized as 32,768 words by 8 bits. Easy memory
expansion is provided by an active LOW Chip Enable (CE) and
active LOW Output Enable (OE) and tri-state drivers. The
device has an automatic power-down feature, reducing the
power consumption by more than 95% when deselected.
An active LOW Write Enable signal (WE) controls the
writing/reading operation of the memory. When CE and WE
inputs are both LOW, data on the eight data input/output pins
(I/O
0
through I/O
7
) is written into the memory location
addressed by the address present on the address pins (A
0
through A
14
). Reading the device is accomplished by selecting
the device and enabling the outputs, CE and OE active LOW,
while WE remains inactive or HIGH. Under these conditions,
the contents of the location addressed by the information on
address pins is present on the eight data input/output pins.
The input/output pins remain in a high-impedance state unless
the chip is selected, outputs are enabled, and Write Enable
(WE) is HIGH. The CY7C1399BN is available in 28-pin
standard 300-mil-wide SOJ and TSOP Type I packages.
