DESCRIPTION The M5M5Y816 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 0.18µm CMOS technology . The M5M5Y816 is suitable f or memory applications where a simple interf acing , battery operating and battery backup are the important design objectiv es. M5M5Y816WG 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.

These dev ices operate on a single +1.65~2.3V 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 t he 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 cycle and must be stable during the entire cy c le. 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 te are in a selectable mode in which both reading and writing are enabled, and lowerby 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 te are in a selectable mode and upperby t e are in a non-selectable mode. Notice: This is not a final specification. Some parametric limits are subject to change. 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 current is reduced as low as 0.5µA(25°C, ty pical), and the memory data can be held at +1.3V power supply , enabling battery back-up operation during power f ailure or power-down operation in the non-selected mode.
