Want to start evaluating the RL78 right away? The Renesas Starter Kit is just what you need. It brings together in a single package all the development tools needed for microcontroller evaluation and initial implementation. The control signals from the microcontroller are output to the expansion board interface of the CPU board, allowing connection to the target system under development for easy debugging.

〈Components of Renesas Starter Kit for RL78〉

• CPU board mounted with RL78
• E1 on-chip debugging emulator
• Free evaluation version of CubeSuite+ integrated development environment (includes coding tool, emulator debugger, etc.)
• Free evaluation version of Renesas Flash Programmer flash programming software

Testing CPU board
Learn more about this product

This target board is for testing RL78 microcontroller applications using the E1 on-chip debugging emulator (sold separately). It can be used for testing at all stages, from software development though actual system operation. All pins of the microcontroller are assigned to peripheral port connectors, making it possible to build evaluation circuits using commercially available universal wiring boards.

Three approaches to debugging
Three approaches to the debugging environment are available for your development needs.

1．Debugging on a PC

[Simulator for CubeSuite+ of RL78 Family, 78K0R and 78K0] Learn more about this product Simulator enabling source-level debugging of applications in the CubeSuite+ integrated development environment before the target system exists Rich break functions and coverage measurement functions Ability to evaluate software modules in a manner very similar to evaluation on the actual device Intuitive graphical user interface (GUI) operability makes your debugging environment highly user-friendly.

2．Debugging with basic functions

[E1 emulator] Learn more about this product This emulator delivers basic debugging capabilities at a low price and supports on-chip trace functionality. 1 Simple to connect. Allows debugging via a connection to the RL78 mounted in the system under development. Can also be used with other Renesas Electronics microcontrollers. USB bus powered. No external power supply required. Also functions as a flash programmer. Environmentally friendly. All materials, from components to packaging, are RoHS compliant. Notes: 1. The on-chip trace function is supported only on versions of the RL78/G14 with a ROM size of 96 KB or more. * The E20 emulator may be used as well, but the supported debugging functions are equivalent to those of the E1.

3．Debugging with high-level functions

[IECUBE] Learn more about this product A high-performance full-spec emulator with highly advanced functions. Trace with time-tag function. Provides access via a GUI to more powerful debugging capabilities, including a duration measurement function and coverage function.

Three approaches to programming
Three approaches to the programming environment are available to meet specific development goals and conditions.

1．Programming controlled by a PC

Flash programming software Renesas Flash Programmer Learn more about this product Download free evaluation version Support for programming controlled by a PC. Graphical user interface (GUI) optimized for programming. Ability to store programming settings in workspace files. Support for two types of programming operation screen (basic mode and full mode) Ability to run scripts Ability to embed unique code Programming via a serial (RS-232C) connection is also supported.

2．Programming controlled by a PC or stand-alone programming

Flash programmer PG-FP5 Learn more about this product Free download Programming GUI for PG-FP5   This programmer allows erasing, programming, and verifying of the software on the target system or a program adapter. Features such as a self-diagnostic function and microcontroller security settings (erasure prevention, reprogramming prevention, etc.) provide peace of mind. Improved functions for production lines (support for on-board/off-board programming and standalone programming). Compact and space-saving. Easy-to-operate key layout.

3．Ordering pre-programmed ROM (growing number of products supported) ¹

Pre-programmed flash memory products from Renesas Electronics Note: 1. The support status differs depending on the product. Please contact the sales company or agent for details.

A wide variety of products for the RL78 family, such as compilers and programmers, are available from partner tool vendors. These products enable the RL78 family to be used in an even broader range of applications.
