Description
The R8C/2B Group is supported only for customers who have already adopted these products. The RL78/G14 Group is recommended for new designs.
The R8C/2A Group and R8C/2B Group of single-chip MCUs incorporates the R8C/Tiny Series CPU core, employing sophisticated instructions for a high level of efficiency. With 1Mb of address space, and it is capable of executing instructions at high speed. In addition, the CPU core boasts a multiplier for high-speed operation processing.
Power consumption is low, and the supported operating modes allow additional power control. These MCUs also use an anti-noise configuration to reduce emissions of electromagnetic noise and are designed to withstand EMI. Integration of many peripheral functions, including multifunction timer and serial interface, reduces the number of system components. Furthermore, the R8C/2B Group has on-chip data flash (1KB × 2 blocks). The difference between the R8C/2A Group and R8C/2B Group is only the presence or absence of data flash. Their peripheral functions are the same.

- Application NoteAI-generated Summary: The document explains how to migrate timer functions from the R8C/36M group's 16-bit Timer RF to the RL78/G14's Timer Array Unit (TAU). Timer RF supports input capture and output compare modes, while TAU offers four independent 16-bit timers with input pulse interval measurement and PWM output functions. Input capture mode measures external signal intervals, and output compare mode triggers pin output changes. TAU channels can combine for high-accuracy timing and flexible pulse generation.Related Files:
- Application NoteAI-generated Summary: The document explains how to migrate timer functions from the R8C/36M Group's Timer RB to the RL78/G14's Timer Array Unit (TAU). It details the correspondence between operation modes: timer mode, programmable waveform generation, programmable one-shot generation, and programmable wait one-shot generation. The RL78/G14 uses four 16-bit timers, which can be combined for higher accuracy. Interval timer, PWM output, and one-shot pulse output functions in TAU replicate the R8C/36M Timer RB modes with enhanced flexibility.Related Files:
- Application NoteAI-generated Summary: The document explains how to implement single master control communication using the R8C/35C Group EC bus interface to issue a restart condition. It demonstrates sending and receiving data with a digital color sensor (S11059-02DT) by alternating master transmission and reception. The restart condition allows switching data direction without issuing a stop condition, complying with I²C protocol standards such as 7-bit slave addressing, approximately 357 kHz transfer rate, and single master communication.Related Files:

- Application NoteAI-generated Summary: The document explains how to register and uninstall Call Walker within the High-performance Embedded Workshop (HEW). It guides users to launch HEW without opening a workspace, access the Tools Administration menu, and register the Call Walker tool by specifying the registration file path. After registration, Call Walker version 2.3 appears in the menu. Upon uninstalling HEW, users must manually delete the remaining Call Walker directory. It also provides Renesas Electronics website and contact information for support. The revision history notes the first edition release date.

- Application NoteAI-generated Summary: The document specifies the serial communication protocols for the R8C/1x and 2x Series microcontrollers in standard serial I/O modes 2 and 3. It details boot program operations including initial settings, communication with a serial programmer, and control commands for flash memory. Communication formats are asynchronous, with defined data transfer structures. Pin assignments and connection examples for both modes are provided. Initial settings cover selecting communication mode based on the MODE pin level after reset and adjusting the bit rate to 9600 bps through a defined handshake process with the serial programmer.View More (171)

(R8C) Are there any hardware precautions for accurate A/D conversion?
In order to perform A/D conversion, it is necessary to fully charge the internal capacitor, but if the impedance of the A/D conversion target is high, the discharge and charge will take time and the conversion value will not be accurate. For correct A/D ...

Can a parallel programmer verify the program in condition the ROM code protect is enabled?
The ROM code protect is enabled at the first MCU reset after setting the ROM code protect function. If there is no reset after writing the program, the program can be verified. Contact the parallel programmer manufacturer for programmer specifications.

What is the reason of reset caused by the watchdog timer?
The RAM is also initialized in the start-up file (ncrt0.a30). It might need several tens of milliseconds to initialize the RAM because of the low-speed on-chip oscillator clock divided by 8 is automatically selected as the CPU clock after reset. Therefore, please refresh the watchdog timer ...
