At any given temperature and voltage condition, tHZ(Max.) is less than tLZ(Min.) both for a given device and from device to device interconnection. 3. If invalid address signals shorter than min. tRC are continuously repeated for over 4us, the device needs a normal read timing(tRC) or needs to sustain standby state for min. tRC at least once in every 4us. -7- Revision 0.0 October 2003 Preliminary UtRAM K1S1616B1A TIMING WAVEFORM OF WRITE CYCLE(1) (WE Controlled) tWC Address tCW(2) tWR(4) CS1 CS2 tAW tBW UB, LB tWP(1) WE tAS(3) tDW Data in High-Z tDH tWHZ Data out High-Z Data Valid tOW Data Undefined TIMING WAVEFORM OF WRITE CYCLE(2) (CS1 Controlled) tWC Address tAS(3) tWR(4) tCW(2) CS1 tAW CS2 tBW UB, LB tWP(1) WE tDW Data Valid Data in Data out tDH High-Z High-Z -8- Revision 0.0 October 2003 Preliminary UtRAM K1S1616B1A TIMING WAVEFORM OF WRITE CYCLE(3) (CS2 Controlled) tWC Address tAS(3) tWR(4) tCW(2) CS1 tAW CS2 tBW UB, LB tWP(1) WE tDW Data Valid Data in Data out tDH High-Z High-Z TIMING WAVEFORM OF WRITE CYCLE(4) (UB, LB Controlled) tWC Address tWR(4) tCW(2) CS1 tAW CS2 UB, LB tBW tAS(3) tWP(1) WE tDW Data Valid Data in Data out tDH High-Z High-Z NOTES (WRITE CYCLE) 1. A write occurs during the overlap(tWP) of low CS1 and low WE. A write begins when CS1 goes low and WE goes low with asserting UB or LB for single byte operation or simultaneously asserting UB and LB for double byte operation. A write ends at the earliest transition when CS1 goes high and WE goes high. The tWP is measured from the beginning of write to the end of write. 2. tCW is measured from the CS1 going low to the end of write. 3. tAS is measured from the address valid to the beginning of write. 4. tWR is measured from the end of write to the address change. tWR is applied in case a write ends with CS1 or WE going high. -9- Revision 0.0 October 2003 Preliminary UtRAM K1S1616B1A PACKAGE DIMENSION Unit: millimeters 48 TAPE BALL GRID ARRAY(0.75mm ball pitch) Top View Bottom View B B1 B 6 5 4 3 2 1 A #A1 B C C C C1 D C1/2 E F G H B/2 Detail A Side View A Y 0.55/Typ.
