S71255-05-000 5/06 FIGURE 16-3: 44-lead Thin Quad Flat Pack (TQFP) SST Package Code: TQJ FIGURE 16-4: 40-contact Very-very-thin Quad Flat No-lead (WQFN) SST Package Code: QI Note: 1. Complies with JEDEC publication 95 MS-026 ACB dimensions, although some dimensions may be more stringent. 2. All linear dimensions are in millimeters (min/max). 3. Coplanarity: 0.1 (±0.05) mm. 4. Package body dimensions do not include mold flash. Maximum allowable mold flash is .25mm. 44-tqfp-TQJ-7 .45 .75 10.00 ± 0.10 12.00 ± 0.25 1.00 ref 0˚- 7˚ 1 11 33 23 12 22 44 34 1.2 max. .95 1.05 .05 .15 Pin #1 Identifier .30 .45 .09 .20 .80 BSC 12.00 ± 0.25 10.00 ± 0.10 1mm Note: 1. Complies with JEDEC JEP95 MO-220I, variant WJJD-5 except external paddle nominal dimensions. 2. From the bottom view, the pin #1 indicator may be either a 45-degree chamfer or a half-circle notch. 3. The external paddle is electrically connected to the die back-side and possibly to certain VSS leads. This paddle should be soldered to the PC board; it is suggested to connect this paddle to the VSS of the unit. Connection of this paddle to any other voltage potential will result in shorts and/or electrical malfunction of the device. 4. Untoleranced dimensions are nominal target dimensions. 5. All linear dimensions are in millimeters (max/min). 40-wqfn-6x6-QI-1 4.1 0.5 BSC See notes 2 and 3 Pin #1 0.30 0.18 0.075 4.1 0.2 6.00 ± 0.10 6.00 ± 0.10 0.05 Max 0.45 0.35 0.80 0.70 Pin #1 TOP VIEW BOTTOM VIEW SIDE VIEW 1mm |
