DESCRIPTION
The M5M5W816 is a f amily of low v oltage 8-Mbit static RAMs organized as 524288-words by 16-bit, f abricated by Mitsubishi's high-perf ormance 0.18m CMOS technology . The M5M5W816 is suitable f or memory applications where a simple interf acing , battery operating and battery backup are the important design objectiv es. M5M5W816WG is packaged in a CSP (chip scale package), with the outline of 7.5mm x 8.5mm, ball matrix of 6 x 8 (48ball) and ball pitch of 0.75mm. It giv es the best solution f or a compaction of mounting area as well as f lexibility of wiring pattern of printed circuit boards. Version, Operating temperature Part name

FUNCTION
The M5M5W816WG is organized as 524288-words by 16-bit. These dev ices operate on a single +2.7~3.0V power supply , and are directly TTL compatible to both input and output. Its f ully static circuit needs no clocks and no ref resh, and makes it usef ul. The operation mode are determined by a combination of the dev ice control inputs BC1# , BC2# , S1#, S2 , W# and OE#. Each mode is summarized in the f unction table. A write operation is executed whenev er the low lev el W# ov erlaps with the low lev el BC1# and/or BC2# and the low lev el S1# and the high lev el S2. The address(A0~A18) must be set up bef ore the write cy c le and must be stable during the entire cycle. A read operation is executed by s etting W# at a high lev el and OE# at a low lev el while BC1# and/or BC2# and S1# and S2 are in an activ e state(S1#=L,S2=H). When setting BC1# at the high lev el and other pins are in an activ e stage , upper-by t e are in a selectable mode in which both reading and writing are enabled, and lower-by t e are in a non-selectable mode. And when setting BC2# at a high lev el and other pins are in an activ e stage, lower-by t e are in a selectable mode and upper-by te are in a nonselectable mode.

8388608-BIT (524288-WORD BY 16-BIT) CMOS STATIC RAM
When setting BC1# and BC2# at a high lev el or S1# at a high lev el or S2 at a low lev el, the chips are in a non-selectable mode in which both reading and writing are disabled. In this mode, the output stage is in a high-impedance state, allowing OR-tie with other chips and memory expansion by BC1#, BC2# and S1#, S2. The power supply c urrent is reduced as low as 0.1A(25C, ty pical), and the memory data can be held at +2.0V power supply , enabling battery back-up operation during power f ailure or power-down operation in the non-selected mode.
