This adaptor is used to program Holtek 8-bit MCU with 44-pin LQFP, FP (footprint) 2.0mm package type. It must be used together with the Holtek e-WriterPro programmer. Note that 44-pin LQFP package has two kinds of footprints: 2.0mm and 3.2mm. Be sure the footprint before purchasing adaptor.

To use this adaptor, insert it into the slot on the e-WriterPro. When placing IC into this adaptor, keep the IC pin1 to align with pin1 of this adaptor (marked on the PCB).

The adapter is a consumable. The suggested programming times is 10000 times. When the adaptor has programmed over 10000 times, the e-WriterPro will display a warning message. It is recommended to replace a new adaptor to ensure successful programming.

The ICP pins (e-CON12A) of the adaptor are not used. The e-WriterPro is capable of performing ICP individually.
