Figure 3.1 Attaching the adapter to a PROM programmer
3.3 Inserting an MCU into the Adapter
(1) For PCA7441
As shown in Figure 3.2, set the slide bar of the IC socket to the right side (marked on the board) and
insert the MCU into the IC socket, with the pin No. 1 of the MCU matched to the pin No. 1 of the IC
socket.
Be careful when attaching to the PROM programmer because an incorrect
insertion can cause fatal damage to the MCU.
3.2 Attaching the Adapter to a PROM Programmer
As shown in Figure 3.1, attach the No. 1 pin of the PCA7402D connector (standard-pitch 28-pin pin-
header mounted) to the No. 1 pin of the IC socket of the PROM programmer.
Be careful when attaching to the PROM programmer because an incorrect
