This device has a built-in internal address generation circuit allowing continuous serial read/write operation by external clock input. Read/write operation causes the internal address to be incremented automatically by +1. External address input enables addressing in units of 1024 words. Furthermore, a refresh timer and a refresh address counter are installed, which makes an external refresh circuit unnecessary. In addition, this configuration allows lower power consumption. The device is packaged in 26/20-pin SOJ or 26/20 TSOP having a width of 300 mil. It is well adapted for storing much data by means of a battery backup. Its combination with our recording and playback LSI enables the easy implementation of a solid recording and playback system. FEATURES • Configuration 4,194,304 x 1 bit • Serial access operation Serial access time : 1.5 ms Serial read/write time : 2.5 ms • Low current drain 100 mA max. (VCC = 3.6 V with data stored and under standard conditions) • Refresh operation A self-refresh function is supported. • Wide operation voltage range Single 2.7 to 3.6 V • Addressing Units of 1024 words • Process 0.45 mm double well CMOS process • Package options : 26/20-pin plastic SOJ (SOJ26/20-P-300-1.27) (Product name : MSM66V84BJS) 26/20-pin plastic TSOP (TSOPII26/20-P-300-1.27-K) (Product name : MSM66V84BTS-K) 1/10 CS RWCK SAS SAD TAS WE tSSC tSAS tSAP tAS tAH A0 A1 DIN DOUT tRWC tTRS tRW tRWP A12 tATS tTAS tRRS tRRH tRWL tRWD tWP tWRS tWRH tACC tOFF n tDS tDH n+1 n+1 tDS tDH n+2 6 Page
