A write occurs during the overlap of a low CS1 , and high CS2, and a high WE. A write begins at the latest transition among CS1 going low,CS2 going high and WE going low. A write ends at the earliest transition among CS1 going high CS2 going low and WE going high. Time tWP is measured from the beginning of write to the end of write. 2. t CW is measured from the later of CS1 going low or CS2 going high to the end of write. 3. t AS is measured from the address valid to the beginning of write. 4. t WR is measured from the earliest of CS1 or WE going high or CS2 going low to the end of write cycle. 5. 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. 6. If CS1 goes low simultaneously with WE going low after WE goes low, the outputs remain in high impedance state. 7. Dout is the same phase of the written data in this write cycle. 8. Dout is the read data of the next address 9. In the write cycle with OE low fixed, tWP must satisfy the following equation to avoid a problem of data bus contention t WP ≥ tWHZ max + tDW min. 9 HM6264BI Series Write Timing Waveform (1) (OE Clock) tWC Address Valid address OE tCW tWR CS1 *1 CS2 tAS WE tAW tWP tOHZ Dout Din High Impedance tDW High Impedance tDH Valid data 10 HM6264BI Series Write Timing Waveform (2) (OE Low Fixed) (OE = VIL ) tWC Address Valid address tAW tCW CS1 *1 tWR CS2 tWP WE tAS tWHZ Dout tOW *2 *3 tOH tDW High Impedance tDH *4 Din Valid data 11 HM6264BI Series Low VCC Data Retention Characteristics (Ta = –40 to +85°C) Parameter VCC for data retention Symbol VDR Min 2.0 Typ*1 Max — — Unit V Test conditions*3 CS1 ≥ VCC –0.2 V, CS2 ≥ VCC –0.2 V or CS2 ≤ 0.2 V Vin ≥ 0 V VCC = 3.0 V, 0 V ≤ Vin ≤ VCC CS1 ≥ VCC –0.2 V, CS2 ≥ VCC –0.2 V or 0 V ≤ CS2 ≤ 0.2 V See retention waveform Data retention current I CCDR — 1* 1 100* 2 µA Chip deselect to data retention time Operation recovery time t CDR tR 0 5 — — — — ns ms Notes: 1.

If CS2 controls data retention mode, Vin levels (address, WE, OE, CS1 , I/O) can be in the high impedance state. If CS1 controls data retention mode, CS2 must be CS2 ≥ VCC – 0.2 V or 0 V ≤ CS2 ≤ 0.2 V. The other input levels (address, WE, OE, I/O) can be in the high impedance state. 12 HM6264BI Series Low V CC Data Retention Timing Waveform (1) (CS1 Controlled) tCDR VCC 4.5 V Data retention mode tR 2.4 V VDR CS1 0V CS1 ≥ VCC – 0.2 V Low V CC Data Retention Timing Waveform (2) (CS2 Controlled) tCDR VCC 4.5 V CS2 VDR 0.6 V 0V 0 V ≤ CS2 ≤ 0.2 V Data retention mode tR 13 HM6264BI Series Package Dimensions HM6264BLPI Series (DP-28) Unit: mm 15 28 35.6 36.5 Max 1 1.2 1.9 Max 14 2.54 Min 5.70 Max 15.24 0.51 Min 13.4 14.6 Max 2.54 ± 0.25 0.48 ± 0.10 0.25 – 0.05 0° – 15° + 0.11 Hitachi Code JEDEC EIAJ Weight (reference value) DP-28 — Conforms 4.6 g 14 HM6264BI Series Package Dimensions (cont.)
