This parameter is sampled and not 100% tested. 3. A write occurs during the overlap (tWP) of a low CS and a low WE. A write begins at the later transition of CS going low or WE going low. A write ends at the earlier transition of CS going high or WE going high. tWP is measured from the beginning of write to the end of write. 4. t CW is measured from CS going low to the end of write. 5. t AS is measured from the address valid to the beginning of write. 6. t WR is measured from the earlier of WE or CS going high to the end of write cycle. 7. During this period, I/O pins are in the output state so that the input signals of the opposite phase to the outputs must not be applied. 8. If the CS low transition occurs simultaneously with the WE low transition or after the WE transition, the output remain in a high impedance state. 9. Dout is the same phase of the write data of this write cycle. 10. Dout is the read data of next address. 11. If CS is low during this period, I/O pins are in the output state. Therefore, the input signals of the opposite phase to the outputs must not be applied to them. 12. In the write cycle with OE low fixed, tWP must satisfy the following equation to avoid a problem of data bus contention. t WP ≥ tDW min + tWHZ max 8 HM628512CI Series Timing Waveforms Read Timing Waveform (WE = VIH) tRC Address tAA tCO CS tLZ tHZ tOE tOLZ OE tOHZ Dout Valid Data tOH 9 HM628512CI Series Write Timing Waveform (1) (OE Clock) tWC Address tAW tWR OE tCW CS *8 tWP tAS WE tOHZ Dout tDW Din 10 Valid Data tDH HM628512CI Series Write Timing Waveform (2) (OE Low Fixed) tWC Address tCW tWR CS *8 tAW tWP WE tOH tAS tOW tWHZ *9 *10 Dout tDW tDH *11 Din Valid Data 11 HM628512CI Series Low VCC Data Retention Characteristics (Ta = –40 to +85°C) Parameter Symbol Min Typ VCC for data retention VDR 2 — Data retention current I CCDR — Chip deselect to data retention time t CDR 0 Operation recovery time tR t RC* 0.8* 4 3 Max Unit Test conditions*2 — V CS ≥ V CC – 0.2 V, Vin ≥ 0 V µA VCC = 3.0 V, Vin ≥ 0 V CS ≥ V CC – 0.2 V See retention waveform 20* 1 — — ns — — ns Notes: 1. 10 µA (max) at Ta = –40 to +40°C. 2.
