I appreciate the detailed datasheet section, but I need to see the pin diagram image(s) to extract the pinout for RA4M1AC3CFP.

You mentioned that 2 images are attached to this message, but I don't see them in the text provided. The pin function tables you've shared list signal names and descriptions, but they do not include pin numbers.

To complete this task, I need:

1. The pin diagram/package drawing image showing the physical pin layout with pin numbers (1, 2, 3, etc.)
2. Confirmation of the package type for RA4M1AC3CFP (e.g., LQFP100, BGA, QFP, etc.)

Please re-attach or re-upload the pin diagram image(s), and I will:

• Read the pin numbers directly from the diagram
• Match them to the signal names in the function tables
• Produce a clean, structured pinout table specific to RA4M1AC3CFP

Once you provide the diagram, I can deliver the complete pinout immediately.

Unless otherwise specified, the electrical characteristics of the MCU are defined under the following conditions:

VCC * 1 = AVCC0 = VCC_USB * 2 = VCC_USB_LDO * 2 = 1.6 to 5.5V, VREFH = VREFH0 = 1.6 to AVCC0, VBATT = 1.6 to 3.6V, VSS = AVSS0 = VREFL = VREFL0 = VSS_USB = 0V, T a = T opr .

Note 1. The typical condition is set to VCC = 3.3V.

Note 2. When USBFS is not used.

Figure 2.1 shows the timing conditions.

Figure 2.1 Input or output timing measurement conditions

The recommended measurement conditions for the timing specification of each peripheral provided are for the best peripheral operation. Make sure to adjust the driving abilities of each pin to meet your conditions.

Each function pin used for the same function must select the same drive ability. If the I/O drive ability of each function pin is mixed, the AC specification of each function is not guaranteed.
