Renesas R5F10EBAANA#U0

Overview

R5F10EBAANA#U0 from Renesas 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, and programmable buzzer output for embedded control in battery-powered industrial sensors and smart home peripherals.

For engineers reviewing the R5F10EBAANA#U0 datasheet, R5F10EBAANA#U0 pinout, R5F10EBAANA#U0 application, or R5F10EBAANA#U0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm) package, 1.6–3.6 V supply range, 32 MHz max CPU frequency (41 DMIPS), and support for real-time clock with calendar/alarm functions in consumer-grade temperature range (−40°C to +85°C).

Technical Context

The R5F10EBAANA#U0 implements the RL78 16-bit CISC core with 3-stage Harvard pipeline, enabling 86% of instructions in 1–2 clock cycles and 16×16 multiply in 1 cycle. Its peripheral set includes two serial array units supporting UART, simplified SPI (CSI), and I²C-each configurable via peripheral I/O redirection register (PIOR).

Power management features include four low-power modes (Stop, Halt, Snooze, Operating), LVD with 12 threshold options, and independent voltage regulator with REGC capacitor support. The on-chip high-speed oscillator delivers ±1% accuracy across 1.8–3.6 V and −20°C to +85°C.

This performance level is confirmed in the official Renesas datasheet R01DS0151EJ0230 Rev.2.30.

Does the R5F10EBAANA#U0 support hardware real-time clock (RTC) functionality?

Yes, the R5F10EBAANA#U0 includes a full-featured RTC with calendar (year/month/day/hour/minute/second), alarm interrupt, and watch correction function. It supports 1 Hz output (RTC1HZ pin) and operates in Halt mode at only 0.57 µA, maintaining accurate timekeeping during ultra-low-power sleep states. This capability is documented in Section 1.1 Features and Block Diagram 1.5.2 of the datasheet.

How many analog input channels does the R5F10EBAANA#U0 support, and what is its ADC resolution?

The R5F10EBAANA#U0 supports 18 analog input channels with 12-bit resolution and a 3.375 µs conversion time. It accepts input voltages down to 1.6 V supply and includes internal voltage reference (1.45 V) and on-chip temperature sensor. These specifications are explicitly listed in the "Rich Analog" section of the R01DS0151EJ0230 datasheet.
