4mbits (512k X 8-bit) Fifo Memory

The AL440B 4Mbits (512k x 8-bit) FIFO memory provides completely independent 8bit input and output ports that CAN operate at a maximum speed of 80 MHz. The built-in address and pointer control circuits provide a very easy-to-use memory Interface that greatly reduces design time and effort. Manufactured using state-of-the-art embedded high density memory cell array, the AL440B uses high performance process technologies with extended controller functions (write mask, read skip.. etc.), allowing easy operation of non-linearity and regional read/write FIFO for PIP, Digital TV, security system and Video camera applications. The status flags CAN be used to indicate Fullness/Emptiness of the FIFO and also allow multiple cascading AL440Bs to expand the storage depth or provide a longer delay, which cannot be achieved with only a single device. Expanding AL440B data bus width is also possible by using multiple AL440B chips in parallel. To get better design flexibility, the polarities of the AL440B control signals are selectable. The read and write control signals, such as Read/Write Enable, Input/Output Enable.., CAN be either active low or high by pulling /PLRTY signal to high or low respectively. In AL440B Window data write/read and data mirroring functions CAN offer better control assistance in the application design. The built-in Registers set CAN be easily programmed via serial bus (I2C like control bus) to perform various useful functions such as multi-freeze, P-in-P in the digital TV, VCR, and Video camera application. Available as a 44-pin TSOP (II), the small footprint allows product designers to keep real estate to a minimum. By Unkown
