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 HM628512B Series Timing Waveforms Read Timing Waveform (WE = VIH) tRC Address tAA tCO CS tLZ tOE tOLZ OE tOHZ tHZ Dout Valid Data tOH 9 HM628512B Series Write Timing Waveform (1) (OE Clock) tWC Address tAW OE tCW CS *8 tWR tAS WE tOHZ Dout tWP tDW Din Valid Data tDH 10 HM628512B Series Write Timing Waveform (2) (OE Low Fixed) tWC Address tCW CS *8 tWR tAW tWP WE tAS tWHZ tOW tOH *9 *10 Dout tDW Din tDH *11 Valid Data 11 HM628512B Series Low VCC Data Retention Characteristics (Ta = –20 to +70 °C) Parameter VCC for data retention Data retention current Symbol VDR I CCDR Min 2 — — — Chip deselect to data retention time Operation recovery time Notes: 1. 2. 3. 4. t CDR tR 0 t RC* 6 Typ — 1* 5 Max — 50* 1 Unit V µA µA µA ns ns Test conditions*4 CS ≥ V CC – 0.2 V, Vin ≥ 0 V VCC = 3.0 V, Vin ≥ 0 V CS ≥ V CC – 0.2 V 1* 5 1* — — 5 15* 2 10* — — 3 See retention waveform For L-version and 20 µA (max.) at Ta = –20 to +40° C.
