NOTES:

1. “M” represents the maximum pin matrix size.

2. “N” represents the maximum allowable number of pins. Number

of pins and location of pins within the matrix is shown on the

pinout listing in this data sheet.

3. Dimension “A1” includes the package body and Lid for both cav-

ity-up and cavity-down configurations. This package is cavity

down. Dimension “A1” does not include heatsinks or other

attached features.

4. Standoffs are required and shall be located on the pin matrix di-

agonals. The seating plane is defined by the standoffs at dimen-

sion “Q1”.

5. Dimension “Q1” applies to cavity-down configurations only.

6. All pins shall be on the 0.100 inch grid.

7. Datum C is the plane of pin to package interface for both cavity

up and down configurations.

8. Pin diameter includes solder dip or custom finishes. Pin tips shall

have a radius or chamfer.

9. Corner shape (chamfer, notch, radius, etc.) may vary from that

shown on the drawing. The index corner shall be clearly unique.

10. Dimension “S” is measured with respect to datums A and B.

11. Dimensioning and tolerancing per ANSI Y14.5M-1982.

12. Controlling dimension: INCH.
