FUNCTIONAL DESCRIPTION
Serial Address Input (SAD) inputting start address read/write. Address data input units 1024 words. 1,024 address data input 10-bit (A0-A9) serial from pin. Serial Address Strobe (SAS) clock used store serial address data into internal register. Address Transfer Strobe (TAS) Input setting serial address data stored address register internal address counter. When falls, address address Read/Write Clock (RWCK) Input data register information read/write clock. Internal operation starts falling edge RWCK. information data register output DOUT read mode, information written into data register write mode. internal address counter automatically incremented when RWCK falls. Write Enable (WE) Input selecting read mode, write mode read modify write mode. read mode when "H", write mode when "L". When falls from while RWCK active, read modify write mode set. Data Input (DIN) Input write data. information data input stored falling edge RWCK write mode, falling edge read modify write mode. Data Output (DOUT) data output always kept high impedance state when RWCK kept "H". When information read read operation, output holds read information until RWCK again "H". early write mode output maintains high impedance state, common operation connecting DOUT possible. Self/Auto Refresh Select (RS/A) selecting refresh mode order retain memory cell data. RS/A level, self-refresh mode selected external refresh control required. RS/A level, auto-refresh mode selected refresh operation required retain memory cell data. Refresh Clock Input (RFSH) Input controlling external refresh when auto refresh mode selected. When autorefresh mode selected, 1024 refresh operations required within 100ms RFSH while RWCK level.

Fast Access Mode Select (FAM) fast read/write operations. Fast read/write possible keeping level. fast access mode released inputting level level when RWCK level, when satisfied. When 1024-word data access complete, sure insert normal cycle order increment address. Chip Select (CS) Input disabling input output pins. This enables parallel multiple MSM63V89Cs connecting data input output pins. Test (TEST) TEST fixed level. Turning power stabilize device, required pause over 100ms after reaches specified voltage. Then needed eight more RWCK cycles (read cycles pseudo data write cycles).
