Overview

Description

The RL78/G1P microcontrollers are the only microcontrollers in the general-purpose RL78 lineup that have a 10-bit D/A converter in addition to a 12-bit A/D converter. They are suitable for a wide variety of applications such as sensor applications and optical transceivers.

Features

  • CPU: RL78 core, Max. 32MHz
  • Voltage: 2.7V to 3.6V
  • Package: 24-pin HWQFN, 32-pin LQFP
  • Memory: SRAM Max. 1.5KB, Program Flash Max. 16KB
  • Timer: 16-bit Timer (ch) x 4, Watchdog Timer (ch) x 1
  • Serial Interface: CSI (ch) x 1, UART (ch) x 1, I2C (ch) x 1
  • Analog function: 8/12-bit A/D Converter (ch) x 6 or 8, 10-bit D/A Converter
  • On-chip Oscillator Freq. (MHz): High-Speed: 32, 24, 16, 12, 8, 6, 4, 3, 2, 1MHz
  • Others: Clock/Buzzer output, Power-On Reset, Low Voltage Detection

FAQs

  1. Evaluation of RL78/G1P

    The RL78/G1P Fast Prototyping Board has a current measurement header to measure the current drawn by the target MCU. For details, refer to “5.13. Current Measurement Header” in the RL78/G1P Fast Prototyping Board User’s Manual (R20UT4661). Also refer to “6. Handling Precautions.”
