AL460 HD FIFO Datasheet
1 GENERAL DESCRIPTION
The AL460 consists of 128-Mbits of memory density and can be configured as an 8M x 16-bit
FIFO (first in first out) at maximum R/W operating speed of 150 MHz. The full HD FIFO can be
used in a wide range of applications such as multimedia, video capture systems and many other
varieties of video data buffering applications. The size and high-speed data access allow full HD
video frame capture up to 1080p resolutions.
The AverLogic AL460 FIFO memory provides completely independent input and output ports. The
built-in address and pointer control circuits provide a straightforward bus interface to sequentially
read/write memory that can reduce inter-chip design efforts.
The AL460 uses high performance process technologies with extended controller functions (write
mask, read skip etc.); it allows easy operation of non-linearity FIFO read/write for use in
broadcasting systems, security systems, cameras and many other applications.
The AL460 is designed and manufactured using state-of-the-art technologies with low power
consumption AC characteristics (2.5V & 3.3V power supply) facilitating high performance and
high quality applications.
The chip is available in LQFP 128-pin with exposed die pad package; the small footprint allows
product designers to keep board real estate to a minimum.

WEN is the write enable signal that controls the 16-bit input
data write and write pointer operation
IE is the data input enable signal that controls the enabling/
disabling of the 16-bit data input pins. The internal write
address pointer is always incremented at the rising edge of
WCLK by enabling WEN regardless of the IE level.
WCLK is the write clock input pin. The write data input is
synchronized with this clock.
The WRST is the write rest signal that resets the write
address pointer to 0.
Write Frame select pin in Two Frame Mode (TFEN = H):
0: Frame 0
1: Frame 1
*Note: For the polarity definition of all write control signals (WEN, IE and WRST), please refer to the
PLRTY pin definition and “Memory Operation” section for details.
