Renesas R5F10EBAANA#20

Overview

R5F10EBAANA#20 from Renesas Electronics is a 32-pin HWQFN-packaged 16-bit RL78/G1A microcontroller with 16 KB flash, 4 KB data flash, 2 KB RAM, 12-bit ADC (18 channels), and ultra-low-power operation down to 0.23 µA in Stop mode. It integrates UART, I²C, SPI, RTC, watchdog timer, and programmable buzzer output for embedded control in battery-powered industrial sensors and smart meters.

For engineers reviewing the R5F10EBAANA#20 datasheet, R5F10EBAANA#20 pinout, R5F10EBAANA#20 application, or R5F10EBAANA#20 equivalent, this page delivers verified electrical specs, validated package dimensions, confirmed peripheral configurations, and real-world use-case guidance aligned with Renesas' RL78/G1A family documentation (R01DS0151EJ0230 Rev.2.30).

Technical Context

The R5F10EBAANA#20 implements the RL78 16-bit CISC core with 3-stage pipeline, delivering 41 DMIPS at 32 MHz using its high-speed on-chip oscillator (±1% accuracy from 1.8–3.6 V). It supports dual-clock domains: main system clock (up to 32 MHz) and subsystem clock (32.768 kHz crystal or low-speed oscillator) for independent RTC operation.

Its peripheral set includes two serial array units (supporting UART, simplified SPI/CSI, and I²C), eight 16-bit timer channels, DMA controller with two channels, and safety features including flash CRC, RAM parity check, and illegal memory access detection-meeting IEC/UL 60730 requirements for functional safety-critical applications.
