Datasheet

Note, the Novato calibration software only works with custom made USB-to-UART programming adapter. This adapter is not provided with
Novato board and has to be requested separately.
Firmware Files
Firmware is developed using Renesas' e2 studio—complete development and debug environment based on the popular Eclipse CDT
project. Use Renesas' E1 Emulator to download firmware through connector J3. The E1 Emulator also provides all the basic debugging
function. For more information regarding RL78 MCU, e2 studio IDE, and E1 emulator, refer to Renesas' website.
The Novato reference design comes with firmware loaded on the system. For additional details, please contact the factory.
HART Communication Protocol
The Novato reference design fully satisfies the HART physical layer requirements. The HART functions set is developed by AB Tech
Solution, an engineering firm specialized in product development services for industrial automation applications.
The HART stack for the Novato reference design supports all universal and common practice commands. The HART stack is not provided
by Maxim Integrated. Contact AB Tech Solution regarding licensing, integration, and further development of device-specific functions.
Lab Measurements
All measurements are taken with the Fluke 724 process calibrator for PT100 RTD. The 4–20mA loop current is measured by the Agilent
34401A digital multimeter as voltage drop over 100½ load resistor. Measurement results are shown in Figure 9 and Figure 10.
