HM62W16255H Series 4M High Speed SRAM (256-kword × 16-bit) ADE-203-751D (Z) Rev. 1.0 Sep. 15, 1998 Description The HM62W16255H is a 4-Mbit high speed static RAM organized 256-kword × 16-bit. It has realized high speed access time by employing CMOS process (4-transistor + 2-poly resistor memory cell)and high speed circuit designing technology. It is most appropriate for the application which requires high speed, high density memory and wide bit width configuration, such as cache and buffer memory in system. The HM62W16255H is packaged in 400-mil 44-pin SOJ and 400-mil 44-pin plastic TSOPII for high density surface mounting.

Transition is measured ±200 mV from steady voltage with Load (B). This parameter is sampled and not 100% tested. 2. If the CS or LB or UB low transition occurs simultaneously with the WE low transition or after the WE transition, output remains a high impedance state. 3. WE and/or CS must be high during address transition time. 4. If CS , OE, LB and UB are low during this period, I/O pins are in the output state. Then the data input signals of opposite phase to the outputs must not be applied to them. 5. t AS is measured from the latest address transition to the latest of CS , WE, LB or UB going low. 6. t WR is measured from the earliest of CS, WE, LB or UB going high to the first address transition. 7. A write occurs during the overlap of low CS , low WE and low LB or low UB . 8. t CW is measured from the later of CS going low to the end of write. 9. t LBW is measured from the later of LB going low to the end of write. 10. t UBW is measured from the later of UB going low to the end of write. 8 HM62W16255H Series Timing Waveforms Read Timing Waveform (1) (WE = VIH) t RC Address tAA tACS CS tOE OE tLB LB tLBHZ 1 * tOHZ *1 tCHZ *1 Valid address tUB UB tLBLZ *1 Dout (Lower byte) High Impedance *4 tUBLZ *1 tOLZ *1 tCLZ *1 High Impedance *4 Valid data tUBHZ1 * *4 tOH Dout (Upper byte) Valid data *4 9 HM62W16255H Series Read Timing Waveform (2) (WE = VIH, LB = VIL , UB, = VIL) tRC Address Valid address tAA tACS tOH tCHZ*1 CS tOE OE tOLZ*1 tCLZ *1 Dout (Lower/Upper byte) High Impedance *4 Valid data *4 tOHZ*1 10 HM62W16255H Series Write Timing Waveform (1) (LB, UB Controlled) tWC Address tAW tAS tWP WE*3 tCW CS*3 Valid address tWR OE tLBW LB tUBW UB tWHZ tOHZ High impedance tOLZ tOW Dout (Lower byte) Dout (Upper byte) High impedance tDW tDH Valid data tDW tDH Valid data Din (Lower byte) Din (Upper byte) 11 HM62W16255H Series Write Timing Waveform (2) (WE Controlled) tWC Address tAW tAS WE*3 tCW CS*3 tWP Valid address tWR OE tLBW LB, UB tWHZ tOHZ Dout (Lower/Upper byte) High impedance *2 tOLZ tOW tUBW tDW tDH Valid data Din (Lower/Upper byte) 12 HM62W16255H Series Write Timing Waveform (3) (CS Controlled) tWC Address Valid address tAW tAS tWP tWR WE *3 tCW CS *3 OE tLBW LB, UB tWHZ tOHZ Dout (Lower/Upper byte) High impedance * *2 4 tUBW tOLZ tOW tDW tDH Valid data Din (Lower/Upper byte) 13 HM62W16255H Series Low VCC Data Retention Characteristics (Ta = 0 to +70°C) This characteristics is guaranteed only for L-version.
