Overview

The R8C/33T Group is supported only for customers who have already adopted these products. The RX130 Group is recommended for new designs.

The R8C/33T 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/33T Group has data flash (1KB × 4 blocks) with the background operation (BGO) function.

  1. R8C/33T SCU and SDMA/DTC questions

    I'm working on a touch project using the R8C/33T, but am having problems which I think relate to the automatic transfer of touch readings from the SCU to RAM.  This can happen via two mechanisms, DTC or SDMA, but the Hardware Manual is very sketchy about any ...

  2. Vdet1 not working as expected

    I have an R8C/33T application that involves occasional writing (at user request, to change settings) to data flash ROM (using the Renesas Virtual EEPROM code).  Because flash operations are only guaranteed down to a supply voltage of 2V7, I want to block flash writing operations when the battery ...

  3. How to set fixed address for RAM variable?

    I'm using HEW Version 4.09.01.007, with M16C Standard Toolchain v5.45.01. I'm writing a touch-sensing application using the R8C/33T MCU.  Data from the SCU can be transferred to RAM by the DTC, but this requires the DTC's destination address to ...

  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. Do I need to rewrite the boot ROM area using MI6C Flash Starter?

    Rewriting of the boot ROM area is unnecessary. This is because M3A-0806 performs programming using the standard boot program which was programmed into the boot ROM area when it was shipped. (#104963)

  3. Please tell me how to set the option function register in detail.

    There are three methods for setting the option function select register using the C complier package M3T-NC30WA: Using the load module converter (lmc30 -R8C) -OFSREGX (or -PROTECTX) option Using assembler directive command .OFSREG (or .PROTECT) By assembly programming The load module converter option and directive command depend on the ...
