Overview

Description

The R8C/L38C 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/L35M Group, R8C/L36M Group, R8C/L38M Group, and R8C/L3AM 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. These groups have data flash (1KB × 4 blocks) with the background operation (BGO) function.

  2. How to normally perform a debugging system of R8C UART monitor program?

    When using the R8C/10 to R8C/17 Groups, since the watchdog timer is not refreshed while the monitor program operates, a watchdog timer interrupt is generated and normal debugging cannot be performed. Do not use the watchdog timer in the user program when using the debugging system ...

  3. SDA fixed low during I2C communication, R8C master

    A clock discrepancy may occur between the master and slave due to noise, etc. on the SCL line of the I2C bus. This occurs due to differences in VIH/VIL characteristics or noise elimination capabilities of the two devices causing a difference in whether or not noise, etc. on ...
