Functional Description
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 tristate 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/O0 through I/O7) is written into the memory location addressed by the address present on the address pins (A0 through A14).
