QFN to DIP Programming Adapters
QFN devices to 0.100″ DIP footprints for programming and development.
Technical Overview
QFN to DIP programming adapters provide a directional interface from QFN (device) to a 0.100″ pitch DIP footprint. These adapters are used in programming, firmware development, and engineering evaluation environments.
Each configuration is defined by QFN package geometry, required DIP span, and routing type. Detailed pin mapping and device-specific wiring are disclosed at the individual product level.
Mechanical Configuration
QFN Interface
- Leadless perimeter pad footprint
- Common pitches: 0.40 mm, 0.50 mm, 0.65 mm, 0.80 mm (SKU-defined)
- Body size defined per device
- Exposed thermal pad supported where applicable
- Interface type: solder-pad or socketed QFN (SKU-defined)
DIP Interface
- 0.100″ (2.54 mm) pitch
- 300 mil (0.300″) span
- 600 mil (0.600″) span where required by pin count
- Through-hole DIP pins for programmer or ZIF socket insertion
Routing Configurations
Routing is determined by the QFN device pinout and the target DIP footprint required by the programming system. The routing type is defined at the product level.
- 1:1 Mapping – Direct pad-to-pin alignment where numbering permits
- Device-Specific Mapping – Pin translation to match programmer definitions
- Defined Skips or Shorts – Implemented where required by device architecture or programming interface
