Product details
Overview
R5F10RGAGFB#10 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 halt mode). It targets battery-powered LCD display systems such as smart meters and industrial HMI panels.
For engineers reviewing the R5F10RGAGFB#10 datasheet, R5F10RGAGFB#10 pinout, R5F10RGAGFB#10 application, or R5F10RGAGFB#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, on-chip LCD drive capability with capacitor-split and internal boost methods, 10-bit ADC with 1.6 V support, and IEC/UL 60730 safety features for functional safety-critical embedded designs.
Technical Context
The R5F10RGAGFB#10 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 with real-time clock (full calendar + alarm + watch correction), 2-channel DMA, UART/I²C/CSI interfaces, and a 10-channel 10-bit ADC with internal 1.45 V reference and on-chip temperature sensor - all operating down to 1.6 V supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10RGCGB#10 | Same 48-pin LFQFP package and RL78/L12 family, but consumer-grade (−40°C to +85°C) and 32 KB flash / 1 KB RAM variant | Not qualified for industrial ambient temperatures; lacks extended temperature validation and some safety features | Select only for cost-sensitive, non-industrial applications where full industrial temp range and safety certification are unnecessary |
| R5F10RLAGFB#10 | 64-pin LFQFP variant with identical industrial rating, same flash/RAM, but adds 10 extra I/O pins and supports up to 39 seg × 8 com LCD | Requires PCB redesign due to larger footprint and pin count; suited for more complex UIs requiring >39 segments or additional peripherals | Choose when higher I/O count, expanded LCD capability, or future scalability outweighs board space constraints |
Compared with R5F10RGAGFB#10, R5F10RGCGB#10 trades industrial temperature and safety robustness for lower cost in commercial environments, while R5F10RLAGFB#10 provides pin-compatible expansion path with greater I/O and LCD segment capacity - both require explicit validation for functional safety or thermal design.

FAQ
What is the maximum operating frequency and power efficiency of the R5F10RGAGFB#10?
The R5F10RGAGFB#10 achieves 31 DMIPS at its maximum operating frequency of 24 MHz using the high-speed on-chip oscillator. Its active power efficiency is 62.5 µA per MHz, and it draws just 0.64 µA in halt mode with RTC and low-voltage detector enabled - making it ideal for long-life battery applications. These values are measured under specified conditions in the official Renesas datasheet R01DS0157EJ0223.
Does the R5F10RGAGFB#10 support LCD drive without external components?
Yes, the R5F10RGAGFB#10 integrates a full LCD controller/driver supporting up to 39 segments and 8 commons. It operates in capacitor-split, internal voltage-boost, or external resistor-division modes. For capacitor-split mode, only two external capacitors (connected to P126/CAPL and P127/CAPH) are required - no external driver IC or charge pump is needed. This is confirmed in Section 1.1 and Figure 1-12 of the R01DS0157EJ0223 datasheet.
What safety certifications or hardware features does the R5F10RGAGFB#10 include for functional safety?
The R5F10RGAGFB#10 includes hardware-level safety features aligned with IEC/UL 60730 Class B requirements: flash memory CRC calculation, RAM parity error checking, SFR write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test. These are implemented in silicon and documented in Section 1.1 "Safety Features" of the R01DS0157EJ0223 datasheet - no external supervision circuitry is required for basic compliance.
Can the R5F10RGAGFB#10 operate from a single 1.6 V supply?
Yes, the R5F10RGAGFB#10 supports operation from 1.6 V to 5.5 V on a single supply rail. Its 10-bit ADC functions down to 1.6 V, and the internal voltage regulator (with REGC decoupling) maintains stable core and peripheral operation across this full range. This capability is explicitly stated in Section 1.1 "Ultra-Low Power Technology" and Table 1-1 of the R01DS0157EJ0223 datasheet.
What debugging interface does the R5F10RGAGFB#10 provide, and how is it accessed?
The R5F10RGAGFB#10 provides a single-wire on-chip debug interface accessible via the TOOL0 pin (P40). This interface supports full firmware download, breakpoint setting, register inspection, and real-time variable monitoring without requiring a dedicated JTAG/SWD header. The debug functionality is enabled by default and requires only one GPIO pin - simplifying PCB layout and reducing test point count. Details are in Section 1.1 "1-wire on-chip debug function" of R01DS0157EJ0223.
