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 7 HM628512BFP Series Timing Waveforms Read Timing Waveform (WE = VIH) tRC Address tAA tCO CS tLZ tHZ tOE tOLZ OE tOHZ Dout Valid Data tOH 8 HM628512BFP Series Write Timing Waveform (1) (OE Clock) tWC Address tAW tWR OE tCW CS *8 tWP tAS WE tOHZ Dout tDW Din tDH Valid Data 9 HM628512BFP Series Write Timing Waveform (2) (OE Low Fixed) tWC Address tCW tWR CS *8 tAW tWP WE tOH tAS tOW tWHZ *9 Dout tDW tDH *11 Din 10 Valid Data *10 HM628512BFP Series Package Dimensions HM628512BFP Series (FP-32D) Unit: mm 20.45 20.95 Max 17 11.30 32 1 1.27 *0.40 ± 0.08 0.38 ± 0.06 0.10 0.15 M *Dimension including the plating thickness Base material dimension 0.12 0.15 +– 0.10 1.00 Max *0.22 ± 0.05 0.20 ± 0.04 3.00 Max 16 14.14 ± 0.30 1.42 0° – 8° 0.80 ± 0.20 Hitachi Code JEDEC EIAJ Weight (reference value) FP-32D Conforms — 1.3 g 11 HM628512BFP Series Cautions 1.
