Description
The R8C/2L Group is supported only for customers who have already adopted these products. The RL78/G1F Group is recommended for new designs.
The R8C/2K Group and R8C/2L 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/2L Group has on-chip data flash (1KB × 2 blocks). The difference between the R8C/2K Group and R8C/2L 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 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 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.

- Application NoteAI-generated Summary: The R8C/25 Group Timer RA operates in Timer Mode by counting an internally generated source with decrement operation. It reloads the count from a register upon underflow and supports programmable divide ratios. The timer starts and stops via specific bits in the TRACR register, and generates interrupts on underflow. Key registers include TRACR, TRAIOC, TRAMR, TRAPRE, and TRA, which control timer operation, I/O functions, mode selection, prescaler, and count values. Writing to these registers affects timer behavior depending on whether counting is active or stopped.Related Files:
- Application NoteAI-generated Summary: The document explains the Timer RA operation in Pulse Output Mode for the R8C/25 Group. It details how the timer counts an internal source and outputs pulses with inverted polarity on underflow. Key registers such as TRACR, TRAIOC, TRAMR, TRAPRE, and TRA control timer start/stop, output polarity, count source, and prescaler settings. The document also covers interrupt generation, pin functions, and register behaviors during count operations.Related Files:View More (157)
