Renesas R5F10RBAGFP#30

Overview

R5F10RBAGFP#30 from Renesas is a 32-pin LQFP ultra-low-power 16-bit RL78/L12 microcontroller with integrated LCD controller/driver, 16 KB flash, 2 KB data flash, 1 KB RAM, and operation from 1.6 V to 5.5 V. It delivers 31 DMIPS at 24 MHz, consumes only 0.64 µA in RTC+LVD halt mode, and supports up to 35-segment × 8-common LCD drive for battery-powered metering and medical displays.

For engineers reviewing the R5F10RBAGFP#30 datasheet, R5F10RBAGFP#30 pinout, R5F10RBAGFP#30 application, or R5F10RBAGFP#30 equivalent, key selection criteria include its 32-pin LQFP-0.8 mm pitch package, on-chip LCD bias generation (capacitor split/internal boost), 10-bit ADC with 1.6 V support, and IEC 60730 safety features for Class B appliance control.

Technical Context

The R5F10RBAGFP#30 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 cycles. It integrates a high-speed on-chip oscillator (24 MHz ±1% over voltage/temperature) and low-speed subsystem clock (32.768 kHz crystal or internal 15 kHz).

Its peripheral set includes one UART, two CSI (SPI-compatible) interfaces, one I²C, eight 16-bit timer channels, real-time clock with calendar/alarm, and DMA with two channels - all optimized for LCD-centric embedded control where low active current (62.5 µA/MHz) and deep-sleep retention are critical.

FAQ

What is the maximum operating frequency and power efficiency of the R5F10RBAGFP#30?

The R5F10RBAGFP#30 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. Its active power efficiency is 62.5 µA/MHz, and it achieves 0.64 µA in halt mode with RTC and LVD enabled - verified in the R01DS0157EJ0223 datasheet under industrial temperature conditions. This makes the R5F10RBAGFP#30 ideal for long-life battery applications.

Does the R5F10RBAGFP#30 support external crystal oscillators?

Yes, the R5F10RBAGFP#30 supports external crystal oscillation via X1/P121 and X2/P122 pins for the main system clock, and XT1/P123 and XT2/P124 for the 32.768 kHz subsystem clock. These pins are fully compatible with standard 32.768 kHz watch crystals and MHz-range ceramic resonators, providing timing accuracy superior to the on-chip oscillator when required.

How many LCD segments and commons does the R5F10RBAGFP#30 drive, and what bias methods are supported?

The R5F10RBAGFP#30 drives up to 35 segments and 8 commons (35 × 8 configuration) using its integrated LCD controller. It supports three bias methods: capacitor split, internal voltage boost (0.63 µA at VDD = 3.0 V), and external resistance division - allowing flexible display selection without external components. All methods are configurable via register settings in the R5F10RBAGFP#30.

What safety certifications or hardware features does the R5F10RBAGFP#30 include for IEC 60730 compliance?

The R5F10RBAGFP#30 includes hardware-level safety features required for IEC 60730 Class B compliance: flash memory CRC calculation engine, RAM parity error detection, SFR write protection, illegal memory access detection, clock frequency monitor, and ADC self-test. These are documented in Section 1.1 Features and Chapter 23 of the R01DS0157EJ0223 datasheet for the R5F10RBAGFP#30.

Can the R5F10RBAGFP#30 operate from a single 1.8 V supply, and what analog features remain functional at that voltage?

Yes, the R5F10RBAGFP#30 operates across 1.6 V to 5.5 V, and all core peripherals - including the 10-bit ADC, LCD controller, and real-time clock - are fully functional at 1.8 V. The ADC maintains 2.1 µs conversion time and supports internal 1.45 V reference voltage, enabling accurate sensing in low-voltage battery systems without level-shifting circuitry for the R5F10RBAGFP#30.
