Function

The PCA4989 is a board that converts an 80-pin 0.65mm-pitch QFP

(80P6S-A) to the standard pitch.

Application

Use the PCA4989 as a test board to connect an 80P6S-A MCU

package to a standard pitch universal board. Since an 80P6S-A IC

socket (IC51-0804-711 made by Yamaichi Electronics Co., Ltd.) is

mounted on the PCA4989, it is easy to replace MCUs.

As the pin layout of the PCA4989 is that of the PCA4979 with two

displaced pins, pin No. 1 of 80P6S-A IC socket of the PCA4989

corresponds to pin No. 3 of the standard pitch hole.
