CY7C1399B Description The CY7C1399B 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 three-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/O0 through I/O7) is written into the memory location addressed by the address present on the address pins (A0 through A14). 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 CY7C1399B is available in 28-pin standard 300-mil-wide SOJ and TSOP Type I packages.
