(2) Connection to the IC socket for 32-pin SDIP
Attach pitch converter board M34513T-PTCA to the 50-wire normal-pitch cable, and connect it
to an IC socket for 32-pin SDIP on the target system.
Use the following products:
(1) 100-wire half-pitch cable (40 cm)
(2) Pitch converter board PCA4029
(3) 50-wire normal-pitch cable (10 cm)
(4) Pitch converter board M34513T-PTCA
Table 3.10 lists the connector assignments of pitch converter board M34513T-PTCA. When
attaching the pitch converter board, check the No. 1 pin positions of the cable and the connector.
Be careful not to connect the cable in a wrong direction.
Table 3.10 Connector assignments of pitch converter board M34513T-PTCA
*1: VDD is not used for inputting power from the target system, but it is used for outputting power
from the power circuit on the M34519T-MCU to the target system. Output of VDD (on/off) is set by
switch SW1. For details, refer to "3.3 Switches" (page 13).
*2: XIN is input from oscillator board OSC-2 on the M34519T-MCU, and it is not input from the
oscillator circuit on the target system. To change a system clock frequency, change the frequency of
oscillator board OSC-2.
