RL78/G1E

Obsolete

Microcontrollers with Built-in Smart Analog for Sensor and Measurement Applications

Overview

The RL78/G1E microcontroller is based on the RL78/G1A and has built-in analog front-end (AFE) for sensor applications. The AFE circuit contains configurable amplifiers capable of various amplifier configurations, a gain adjustment amplifier, filters, D/A converters, and a temperature sensor, which are suitable for processing small sensor signals.

  1. SPI, W5500, RL78/G1F R5F11BLE

    Greetings,   I want to connect a W5500 Ethernet Port with a RL78/G1F R5F11BLE. Can Someone provide a Library for SPI, that I could use? I'm using IAR and Aplilet. An example code with many comments would be great.   Thanks.

  1. If RL78 Accepts External Interrupt Requests That Occur Immediately After Reset

    No, that interrupt request will not be accepted. After a reset, the registers are initialized to the state of no interrupt request and no interrupt processing allowed, and therefore are in a state in which no external interrupt request can be accepted. Refer to the user’s manual of each ...

  2. Tell me the points to be aware of when using the RL78 Code Generator with the WDT.

    In the RL78 Code Generator, the Watchdog Timer (WDT) is set to 'Enabled' by default, as shown in the diagram below. To avoid unintended resets by the WDT, please either select 'Disabled' for the 'Watchdog Timer Operation Setting' or add a program to clear the Watchdog Timer counter.
