Product Summary
The AL422B-PBF consists of 3M-bits of DRAM, and is configured as 393,216 words x 8 bit FIFO (first in first out). The interface is very user-friendly since all complicated DRAM operations are already managed by the internal DRAM controller. Current sources of similar memory (field memory) in the market provide limited memory size which is only enough for holding one TV field, but not enough to hold a whole PC video frame which normally contains 640x480 or 720x480 bytes. The AverLogic AL422B-PBF provides 50% more memory to support high resolution for digital PC graphics or video applications. The 50% increase in speed also expands the range of applications.
