Grouping [ ] RL78 Family is divided into some groups, those have unique naming rules.

• G1x: For general purpose use • L1x: For controls • I1x: Mainly for industrial use • F1x: For automotive use • D1x: Specially designed for automotive customers only Application examples [ ] RL78 is suitable for, such as (including;,,,, and ), (including;,, and ), and (including;,, ). It is also used for (including;,, and ), and (including;,, and ). For, low-power and size constrained applications are ideally suited to RL78's automotive dedicated communication interfaces, such as,, and,: 4 and solutions. Three special grade of maximum, 105 °C (221 °F), 125 °C (257 °F), and 150 °C (302 °F), are available for some products.: 2 History [ ] RL78 (130nm MF3 flash process) was the first new MCU to emerge from the new Renesas Electronics company from the merger of NEC Electronics and Renesas Technology and incorporated the features of the NEC 78K0R (150nm MF2 flash process) and Renesas Technology microcontrollers.

With more than 4,000 supported Renesas devices, IAR Embedded Workbench supplies exceptional design flexibility for embedded developers working with. IAR Embedded Workbench® for Renesas Synergy™ offers tools for efficient code development, including a highly optimizing C/C++ compiler and linker, and C-STAT® Static Analysis and C-RUN® Runtime Analysis tools that allow developers to find potential code issues early in the development process.

The RL78 core variants include the S1, S2, and S3 type cores which evolved from the NEC 78K0R core. The basic S1 core support 74 instructions, the S2 core adds register banking and supports 75 instructions, while the S3 core adds an on-chip multiplier / divider / multiple-accumulate and supports 81 instructions. The RL78 was developed to address extremely low power but highly integrated microcontroller applications, to this end the core offered a novel low power mode of operation called “snooze mode” where the or can be programmed to meet specific conditions to wake the device from the extreme low power STOP mode of 0.52uA. Software and development tools [ ] RL78 Family is supported with a various range of hardware and software. Compilers and IDEs [ ] The, Renesas CS+ (formerly CubeSuite+), Renesas e 2studio (based on ), and ' compiler and development environment are available.

The Renesas CS+ is free for debug-only use and supports standard executable files. The RL78 defined by Renesas is compatible with IAR's V2 and higher compilers. Real-time operating systems [ ] Regarding, CMX Systems, Inc.' S CMX-RTX,,,, and are supported. Code generating tools [ ] Renesas provides a free code generating tool named APPLIcation LEading Tool (Applilet). Flash ROM programming libraries [ ] Renesas provides free self-programming libraries; Code Flash Libraries (CFL) and Data Flash Libraries (DFL). A EEPROM Emulation Library (EEL) is also available for the data-flash to add and robustness.

Different classes of DFL and EEL are available to match application needs including the standard T01 type, 'Tiny' T02 type, and 'Pico' T04 type (DFL-only). In-circuit emulators [ ] Several companies provide on-chip debuggers and full-spec. Renesas makes on-chip debuggers as well as third-parties, such as and iSystems. Renesas and iSystems supply full-spec in-circuit emulators. On-chip device programming tools [ ] Device programming can be achieved by using the on-chip or by using the special serial programming mode of the devices.

Renesas supports the serial programming mode with debug tools via the Renesas Flash Programmer (RFP) and the stand-alone programmers; PG-FP5 and PG-FP6, while several third-parties support RL78 with their own device programmers. Variants [ ] RL78 Family has a range of devices from 20pin with 16K Byte to 128pin with 512K Byte flash memory. Serial number idm.
