Description
The AL460 consists of 128Mbit of memory density,
and is configured as 8,192K x 16 bits FIFO (First-In-First-Out),
the optimized access scheme offers maximum R/W operating speed up to 150 MHz.
The FIFO provides simple and easy-to-use user interfaces facilitating usage in a wide range of applications,
such as Multimedia systems, video capture systems, and various video data buffering applications.
The extensive memory size and high data-access-speed allow video frame capturing up to Full HD (1080p) resolution.
Complementing the Double Buffer mode, 2 banks serve as upper and lower banks (with 4,096k x 16-bit of each bank),
AL460 can be further manipulated into more sophisticated applications.
The R/W operations of corresponding banks are acknowledged while high/low signals present at the bank control pins.
All AL460 FIFO specifics,
like completely independent input and output controls,
built-in address and pointer control circuits,
bank switching and other management tasks provide data
integrity during access and straightforward bus interface
for a sequential data read/write that reduce inter-chip design efforts.
The Double-Buffer mode allocates video data capture
without reading a mixed old and new data frames.
The polarity control seamlessly matches the controller waveform without additional glue-logic.
The AL460 is also implemented with high performance process
technologies with extended controller functions (write mask, read skip .. etc.);
allowing easy operation of FIFO read/write for use in broadcasting systems,
security systems, cameras, and many other applications.
Designed and manufactured using state-of-the-art technologies,
AL460 achieved high performance and low power consumption
AC characteristics (2.5/3.3V power supply),
for the most sophisticated applications.
The chip is available as an LQFP-128 package;
the small footprint keeps real estate of any designs to a minimum. |
