CONFIGURATION (TOP VIEW) lead package(SOJ). These device operate single 3.3V supply, directly chip select compatible. They include power down feature well. input data inputs/ FEATURES outputs Fast access time M5M5V4R08J-12 12ns(max) (3.3V) M5M5V4R08J-15 15ns(max) (0V) data power dissipation Active 363mW(typ) inputs/ Stand 3.3mW(typ) outputs Single +3.3V power supply write control input Fully static operation clocks, refresh Common data Easy memory expansion address inputs Three-state outputs OR-tie capability prevents data contention Directly compatible inputs outputs M5M5V4R08J offered 36-pin plastic small outline Jaddress inputs address inputs output enable input data inputs/ outputs (0V) (3.3V) data inputs/ outputs address inputs M5M5V4R08J Outline 36P0K (SOJ) APPLICATION High-speed memory units PACKAGE 36pin 400mil BLOCK DIAGRAM address inputs ADDRESS DECODERS INPUT BUFFERS OUTPUT BUFFERS data inputs/ outputs MEMORY ARRAY ROWS 8192 COLUMNS COLUMN CIRCUITS COLUMN ADDRESS COLUMN DECODERS ADDRESS DATA INPUT BUFFERS DECODERS COLUMN INPUT BUFFERS (3.3V) (0V) address inputs MITSUBISHI ELECTRIC M5M5V4R08J-12,-15 4194304-BIT (524288-WORD 8-BIT) CMOS STATIC FUNCTION operation mode M5M5V4R08J determined combination device control inputs Each mode summarized function table. write cycle executed whenever level overlaps with level address must set-up before write cycle must stable during entire cycle. data latched into cell trailing edge whichever occurs first, requiring set-up hold time relative these edge maintained. output enable input directly controls output stage. Setting high level, output stage high impedance state, data contention problem write cycle eliminated. read cycle excuted setting high level level while active state (S=L). When setting high level, chip nonselectable mode which both reading writing disable. this mode, output stage highimpedance state, allowing OR-tie with other chips memory expansion Signal-S controls power-down feature. When goes high, power dissapation reduced extremely. access time from equivalent address access time.
