Description
The R8C/LA8A Group is supported only for customers who have already adopted these products. The RL78/L13, RL78/L1C Groups are recommended for new designs.
The R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, and R8C/LA8A Group of single-chip MCUs incorporate the R8C CPU core, which implements a powerful instruction set for a high level of efficiency and supports a 1Mb address space, allowing execution of instructions at high speed. In addition, the CPU core integrates a multiplier for high-speed operation processing.
Power consumption is low, and the supported operating modes allow additional power control. These MCUs are designed to maximize EMI/EMS performance. Integration of many peripheral functions, including multifunction timer and serial interface, helps reduce the number of system components. The R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, and R8C/LA8A Group have data flash.

- Application NoteAI-generated Summary: The document explains how to migrate timer functions from R8C/36M's Timer RC to RL78/G14's Timer Array Unit (TAU). It covers three main modes: timer mode with input capture, timer mode with output compare, and PWM mode. RL78/G14 uses multiple 16-bit timer channels that can operate independently or combined for high accuracy. The PWM2 mode of R8C/36M is not supported by RL78/G14 but can be implemented using other RL78 series timers.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 details the standard serial I/O mode serial protocol for the R8C/Mx Series LAxA Group. It covers boot program content including initial settings, communication with a serial programmer, and control commands such as flash programming, erasing, and reading. Communication supports two asynchronous modes: standard serial I/O mode 2 and mode 3, each with defined data formats and pin assignments. The MODE pin selects the communication mode and functions as TXD or RXD in mode 3. Additional pins like RESET, Vcc, Vss, and VREF have specific roles in communication and voltage referencing.
- Application NoteAI-generated Summary: The document compares peripheral functions of the R8C/L38M, R8C/LA8A, and RL78/L13 MCU groups to guide replacements of R8C with RL78. It details reset types, port controls, oscillators, timers, watchdog timers, voltage detection, flash memory modes, interrupts, and DMA features. The comparison highlights similarities and differences in peripheral functions without covering CPU core differences.View More (137)
