18 | # The information for these packages comes from various sources: |
19 | # |
20 | # - the C8051F326 data sheet, for the QFN28 footprint (N: mcu) |
21 | # - the AT86F326 data sheet, for the QFN32 package dimensions (N: txrx) |
22 | # - Atmel's general recommendations for QFN land patterns (N: atmel-qfn) |
23 | # - NXP's SOT617-1 and SOT617-3, for package and land pattern: |

81 | # Note: footprint changes with PCB thickness ! |
82 | # |
83 | # Known bugs: |
84 | # - keepout area marker should be on comment layer |
85 | # - pin 2 should be off-center and extend such that proper trace can be |
86 | # connected directly |

93 | # Note: the signal pads are enlarged by 0.2 mm and their center is shifted by |
94 | # 0.1 mm with respect to the reference. |
95 | # |
96 | # According to the data sheet, the leads terminate at (2.00+/-0.10 mm)/2+ |
97 | # 2.48 mm = 3.48+/-0.10 mm from the center. The reference footprint puts the |
98 | # edge of the pads at (2.00+/-0.10 mm)/2+2.6 mm = 3.6 mm+/-0.10 mm, so the |
99 | # maximum lead end could be at 3.58 mm while the minimum pad edge could be at |
100 | # 3.5 mm. |
101 | # |
102 | # Assuming that the pad is intended to extend a bit beyond the lead, we need |
103 | # to add 0.2 mm to compensate for these tolerances. (The pad tolerance may not |
104 | # be intended to be used this way, however, we still have to consider small |
105 | # errors in registration, which also amount to about 0.1 mm, so the calculation |
106 | # remains valid.) |
