1998 MSM548333 Previous version: Dec.
1996 240,384-Word ¥ 8-bit + 240,384-Word ¥ 4-bit Triple Port type Field Memory The MSM548333 is a high performance double triple-port type 2.
88-Mbit, 768 bits ¥ 313 lines ¥ (8 + 4), Field Memory for Y-C separation signal control.
The MSM548333 has two memory plain blocks: Y area has 8 plains and C area has 4 plains.
Each plain contains 768 ¥ 313 bits.
Each plain has one input port and two output ports.
Access is done line by line.
The line address must be set each time a line is changed.
The MSM548333 is especially designed for high performance digital cameras, TVs, VTRs and Multimedia applications which require special operations such as time-base correction, noise reduction and other digital techniques.
The MSM548333 is not designed for high end use in such applications as medical systems, professional graphics systems which require long term picture storage, data storage systems and others.
More than two MSM548333s can be cascaded directly without any delay devices between them.
Cascading MSM548333s provides larger capacity and longer delay.
X and Y serial address input enables random initial address setting of serial access in a page.
Other than the random address setting, MSM548333 has several types of address set modes such as line hold, address jump to initial address and line increment.
For example, address jump to initial X address and line increment enable block access.
Self refresh function releases the MSM548333 from being applied external refresh control clocks even though it contains dynamic type memory cells.
Input enable control or IE pin enables write mask function.
