MSM548332 Datasheet | OKI Electric

DESCRIPTION The MSM548332 is a 3.3-Mbit, 960 bits - 290 lines, Field Memory. Access is done line by line. The line address must be set each time a line is changed. More than two MSM548332s can be cascaded directly without any delay devices between them. Cascading MSM548332s provides larger capacity and longer delay. X serial address input enables random initial address setting of serial access in a page. Other than the random address setting, MSM548332 has several types of address set modes such as line hold, address jump to initial address and line increment. Self refresh function releases the MSM548332 from being applied external refresh control clocks even though it contains dynamic type memory cells. MSM548332 has write mask function or input enable function (IE), and read-data skipping function or output enable function (OE). The MSM548332 is especially designed for digital TVs and VTRs for consumer use and video cameras. The MSM548332 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.
