Renesas R5F10RGAGFB#30

Overview

R5F10RGAGFB#30 from Renesas is a 48-pin LFQFP, 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 (up to 39 seg × 4 com), and ultra-low-power operation (0.64 µA in RTC+LVD mode). It targets battery-powered LCD instrumentation, smart meters, and industrial HMI panels requiring high integration and long runtime.

For engineers reviewing the R5F10RGAGFB#30 datasheet, R5F10RGAGFB#30 pinout, R5F10RGAGFB#30 application, or R5F10RGAGFB#30 equivalent, key selection criteria include its 48-pin LFQFP (7 mm × 7 mm, 0.5 mm pitch) package, on-chip LCD drive capability with capacitor-split or internal-boost methods, 10-bit ADC (10 channels), and IEC/UL 60730 safety features for certified embedded control.

Technical Context

The R5F10RGAGFB#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: high-speed on-chip oscillator (24 MHz ±1% over voltage/temperature) and subsystem clock (32.768 kHz crystal or low-speed internal oscillator).

Its peripheral set includes an 8-channel timer array unit, real-time clock with calendar/alarm, 2-channel DMA, UART/I²C/CSI interfaces, and programmable key return (KR0–KR3) for keypad scanning - all optimized for low-voltage (1.6 V–5.5 V) LCD-centric applications.

FAQ

What is the maximum operating frequency and power efficiency of the R5F10RGAGFB#30?

The R5F10RGAGFB#30 operates at up to 24 MHz using its high-speed on-chip oscillator (±1% accuracy), 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-critical for battery-powered LCD applications where runtime and wake-up latency are tightly constrained. This efficiency is validated across the full −40°C to +105°C industrial temperature range.

Does the R5F10RGAGFB#30 support multiple LCD drive methods, and how are they configured?

Yes, the R5F10RGAGFB#30 supports three LCD drive methods: capacitor-split (0.12 µA), internal voltage boost (0.63 µA at 3.0 V), and external resistance division. Configuration is done via LCD control registers (LCDCR0–LCDCR2) and pin assignments (VL1–VL4, CAPL/CAPH). The capacitor-split method uses external capacitors on CAPL/CAPH pins; internal boost activates the on-chip charge pump; resistance division routes bias through external resistors-enabling optimization for power, contrast, or component count.

What safety certifications or hardware features does the R5F10RGAGFB#30 include for industrial use?

The R5F10RGAGFB#30 includes hardware-level safety features aligned with IEC/UL 60730 Class B requirements: flash memory CRC calculation, RAM parity error detection, SFR write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test. These features reduce software certification burden and ensure robust operation in safety-critical industrial controls-verified in Renesas' official safety manual R01US0147EJ0200.

How many ADC channels and what resolution does the R5F10RGAGFB#30 provide?

The R5F10RGAGFB#30 integrates a 10-bit successive-approximation ADC with up to 10 input channels (ANI0–ANI23, configurable per pin mapping), 2.1 µs conversion time, and support for 1.6 V minimum supply. It includes an internal 1.45 V reference voltage and on-chip temperature sensor-enabling direct measurement of system temperature, battery voltage, or sensor signals without external components.

What is the pin count, package type, and industrial temperature rating of the R5F10RGAGFB#30?

The R5F10RGAGFB#30 uses a 48-pin LFQFP package (7 mm × 7 mm, 0.5 mm pitch) with G-suffix indicating industrial temperature range (−40°C to +105°C). This compact, fine-pitch package supports high-density PCB layouts while maintaining thermal reliability in enclosed enclosures, DIN-rail mounts, and sealed meter housings-validated per JEDEC JESD22-A108F humidity testing and JESD22-A104 temperature cycling.
