Renesas R5F10RLAGFB#30

Overview

R5F10RLAGFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade (−40°C to +105°C) 16-bit RL78/L12 microcontroller with 32 KB flash, 2 KB data flash, 1.5 KB RAM, integrated LCD controller/driver supporting up to 39 seg × 4 com or 35 seg × 8 com, and ultra-low-power operation (0.64 µA in RTC+LVD halt mode). It targets battery-powered LCD display systems such as smart meters and industrial HMI panels.

For engineers reviewing the R5F10RLAGFB#30 datasheet, R5F10RLAGFB#30 pinout, R5F10RLAGFB#30 application, or R5F10RLAGFB#30 equivalent, key selection criteria include its on-chip LCD drive capability, 24 MHz high-speed on-chip oscillator (±1% accuracy), 10-bit ADC with internal reference, I²C/SPI/UART interfaces, and IEC 60730 safety features for certified embedded control.

Technical Context

The R5F10RLAGFB#30 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 clock cycles. It supports dual-clock domains: a 24 MHz high-speed on-chip oscillator (±1% over 1.8–5.5 V and −20°C to +85°C) and a 32.768 kHz subsystem crystal oscillator for RTC.

Its integrated LCD controller supports three drive methods-capacitor split, internal voltage boost, and resistance division-with 16-step contrast adjustment and blinking control. The device includes two DMA channels, 8-channel 16-bit timer array, real-time clock with calendar/alarm, and hardware CRC for flash integrity verification.

FAQ

What is the maximum operating frequency and power consumption of the R5F10RLAGFB#30?

The R5F10RLAGFB#30 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS. Its active power consumption is 62.5 µA/MHz, and in halt mode with RTC and LVD enabled, it draws just 0.64 µA-enabling multi-year battery operation in metering and portable applications. The device also supports snooze mode for low-latency wake-up from deep sleep.

Does the R5F10RLAGFB#30 support external crystal oscillators, and what frequencies are compatible?

Yes, the R5F10RLAGFB#30 supports two independent crystal oscillators: a main system clock (X1/X2) accepting 1–20 MHz crystals for high-precision timing, and a subsystem clock (XT1/XT2) designed for standard 32.768 kHz watch crystals to drive the real-time clock independently. Both operate across the full 1.6–5.5 V supply range and −40°C to +105°C temperature range.

How many LCD segments and commons does the R5F10RLAGFB#30 support, and what drive methods are available?

The R5F10RLAGFB#30 supports up to 39 segments and 8 commons (35 seg × 8 com) or 39 segments and 4 commons (39 seg × 4 com). It implements three LCD drive methods: capacitor split, internal voltage boost (0.63 µA @ 3.0 V), and external resistance division-each selectable via register configuration to match display glass requirements and power budgets.

What safety certifications or built-in features does the R5F10RLAGFB#30 provide for industrial applications?

The R5F10RLAGFB#30 includes hardware-level safety features aligned with IEC 60730 Class B requirements: flash memory CRC calculation, RAM parity error checking, SFR and RAM write protection, illegal memory access detection, clock frequency monitoring, ADC self-test, and a windowed watchdog timer. These features reduce certification effort for industrial control and white-goods applications.

Is the R5F10RLAGFB#30 pin-compatible with other RL78/L12 variants, and what package options exist?

The R5F10RLAGFB#30 uses a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch) package and is not pin-compatible with 32-, 44-, 48-, or 52-pin RL78/L12 variants due to differing pin counts and signal allocations. Other 64-pin options include HWQFN (R5F10RLAGNB) and LQFP (R5F10RLAGFA), but none share identical pinouts-PCB layout must be specific to the LFQFP variant used in R5F10RLAGFB#30.
