Description

The R8C/36C Group is supported only for customers who have already adopted these products. The RL78/G14, RL78/G1F Groups are recommended for new designs.

The R8C/36C Group of single-chip MCUs incorporates the R8C 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 are designed to maximize EMI/EMS performance. Integration of many peripheral functions, including multifunction timer and serial interface, reduces the number of system components. The R8C/36C Group has data flash (1KB × 4 blocks) with the background operation (BGO) function.

    AI-generated Summary: Timer RG supports timer mode (input capture and output compare), PWM mode, and phase counting mode in both R8C/36M and RL78/G14. Input capture transfers TRG register values on input edges, while output compare outputs signals at specified levels. PWM mode outputs waveforms with adjustable duty cycles. Phase counting mode measures counts from two-phase encoders. Migration from R8C/36M to RL78/G14 is feasible due to identical operation modes, with sample codes and application notes available for reference.

    PDF 412 KB R01AN4464EJ0100 Rev.1.00 日本語 Oct 26, 2018
    AI-generated Summary: The document explains the differences in flash memory functions between the R8C/36M Group and RL78/G14. It outlines the flash memory map and rewrite modes of the R8C/36M Group, including CPU rewrite mode, standard serial I/O mode, and parallel MO mode. The user ROM area is divided into blocks and can be rewritten using different methods, such as software commands from the CPU or external programmers. The boot ROM area stores the standard boot program for serial I/O rewriting.

    RL78/G14, R8C/36M Group Migration Guide from R8C to RL78: Timer RA to Timer RJ Rev.1.01
    PDF 1.09 MB R01AN4216EC0101 Rev.1.01 日本語 Oct 22, 2018
    AI-generated Summary: The document explains how to migrate from the R8C/36M Group's Timer RA to the RL78/G14's Timer RJ, covering five operational modes: timer mode, pulse output mode, event counter mode, pulse width measurement mode, and pulse period measurement mode. Timer RA is an 8-bit timer with an 8-bit prescaler, while Timer RJ is a 16-bit timer with a reload register and down counter. Both timers support equivalent functions, including counting internal or external pulses and measuring pulse width or period. The guide details hardware configurations, software descriptions, option byte settings, function specifications, and flow charts for each mode.

    AI-generated Summary: The document explains how to migrate the D/A converter functionality from the R8C/36M Group to the RL78/G14 family with 96-KB or larger flash memory. It compares the specifications, highlighting differences such as the reference voltage source (Vref pin for R8C/36M and Vpp pin for RL78/G14) and output pins. It also details register differences and recommends selecting normal mode on RL78/G14 to match R8C/36M operation. Related manuals and technical updates are referenced for further information.

  1. Data Flash of R8C/2B and R8C/36C

    ... found the controller is forecored to reset continuously and checked it's caused by the whole progress of erase and write is over 260ms.Is there any idea to solve this problem? Is the new funtion of R8C/36C, BGO supported able to make useful for my case?Thanks!

  1. (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 ...

  2. 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.

  3. What will happen if the MCU starts operating before oscillation is stabilized?

    Serial interfaces and timers may not be able to operate correctly. If the CPU clock is switched from "division by 8" to "no divisions" before oscillation is stabilized, the program will not perform properly because the CPU cannot fetch the program codes correctly. Timers, A/D converter and serial ...
