YRDKRX62N Datasheet, PDF (19/43 Pages) Renesas Technology Corp – Renesas Demonstration Kit (RDK) for RX62N User’s Manual: Hardware

The National Semiconductor 10/100 DP83640 Precision PHYTER^ Ethernet PHY supports the IEEE1588 Precision Time Protocol (PTP)
providing precision clock synchronization for real-time industrial connectivity. The RDK includes a GPIO/Interrupt connection between the PHY
and the RX62N for PTP event processing, and a direct LED connection for timing indications. The DP83640 captures a time stamp at the
physical layer level with an accuracy of <10ns. Note: National Semiconductor recommends using the DP83848J as it is less expensive if
1588 is not necessary.

6.11. 3 – Axis Accelerometer
The RDK includes an Analog Devices ADXL345 3–axis accelerometer. The part is connected to I2C SDA (Micro Pin 33)
and SCL (Micro Pin 34).
6.12.Digital Temp Sensor
An ADT7420 Digital Temperature Sensor is also on the RDK. It is connected to the I2C SDA (Micro Pin 33) and SCL pins
(Micro Pin 34).
6.13. Option Links and Jumper Settings
Table 6-9 and 6-10 detail the function of the various option links contained on the RX62N RDK. The default configuration is indicated by BOLD
text. Table 6-9 details the Ethernet LED Configuration Resistor.
