CAS can remain high during the refresh sequence to conserve power. power up To achieve proper operation, an initial pause of 200 µs followed by a minimum of eight initialization cycles is required after full VCC level is achieved. These eight initialization cycles need to include at least one refresh (RAS-only or CBR ) cycle. single-in-line memory module and components PC substrate: 1,27 ± 0,1 mm (0.05 inch) nominal thickness; 0.005 inch/inch maximum warpage Bypass capacitors: Multilayer ceramic Contact area for TM497FBK32H and TM893GBK32H: Nickel plate and gold plate over copper Contact area for TM497FBK32I and TM893GBK32I: Nickel plate and tin-lead over copper |
