4Mbyte(1Mx32) Fast Page Mode, 1K Refresh, 72Pin SIMM, 5V Design Part No. HMD1M32M2GL DESCRIPTION The x 32 bits Dynamic RAM MODULE which is assembled 2 pieces x 16bit DRAMs in 42 pin SOJ package on single sides the printed circuit board with decoupling capacitors. The HMD1M32M2GL is optimized for application to the systems, which are required high density and large capacity such as main memory of the computers and an image memory systems, and to the others, which are, requested compact size. The HMD1M32M2GL provides common data and outputs. w 72 pins Single In-Line Package w Fast Page Mode Capability w Single +5V� 0.5V power supply w Fast Access Time & Cycle Time tRAC HMD1M32M2G-6 w Low Power w /RAS Only Refresh, /CAS before /RAS Refresh, Hidden Refresh Capability w All inputs and outputs TTL Compatible w 1,024 Refresh 50 60 tCAC 15 tRC 90 110 tPC 35 40 PIN SYMBOL Vss DQ3 DQ19 Vcc /WEO DQ21 DQ6 PIN SYMBO A8 NC(A10) Vcc /WE2 NC Vcc /RAS Vcc NC /OE Vss /CAS Vcc NC(A11) /WE1 Vcc PIN SYMBOL DQ31 DQ15 Vcc NC Vss NC Vss PIN � DQ31 /RAS /CAS /OE FUNCTION Address Inputs Data Input/Output Row Address Strobe Column Address Strobe Data Output Enable PIN /WE Vcc Vss NC FUNCTION Read/Write Enable Power (+5V) Ground No Connection SYMBOL TA TSTG VIN/VOUT VCC IOUT PD PARAMETER Ambient Temperature under Bias Storage Temperature (Plastic) Voltage on any Pin Relative to Vss Power Supply Voltage Short Circuit Output Current Power Dissipation RATING *NOTE: 1.
