Product details
Overview
R5F10RLCAFB#10 from Renesas is a 64-pin LFQFP-packaged 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, thermostats, and portable medical devices.
For engineers reviewing the R5F10RLCAFB#10 datasheet, R5F10RLCAFB#10 pinout, R5F10RLCAFB#10 application, or R5F10RLCAFB#10 equivalent, key selection criteria include its 24 MHz max CPU speed (31 DMIPS), on-chip 24 MHz ±1% oscillator, 10-bit ADC with internal reference, and support for capacitor-split and internal-boost LCD drive methods across consumer-grade −40°C to +85°C operation.
Technical Context
The R5F10RLCAFB#10 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, enabling 86% of instructions in 1–2 clock cycles. Its low-power design integrates multiple sleep modes (Stop at 0.23 µA, Halt at 0.64 µA), snooze functionality, and dedicated LCD voltage regulators (VL1–VL4) with external capacitor support (CAPL/CAPH).
It features dual-clock domains: high-speed main system clock (24 MHz on-chip oscillator or crystal up to 20 MHz), and subsystem clock (32.768 kHz XT1/EXCLKS for RTC). Peripheral I/O redirection (PIOR) enables flexible pin assignment for timers, UART, CSI, and IICA interfaces without hardware changes.

FAQ
What is the maximum operating frequency and performance of the R5F10RLCAFB#10?
The R5F10RLCAFB#10 operates at up to 24 MHz using its on-chip high-speed oscillator and delivers 31 DMIPS. Its RL78 16-bit CPU core executes 86% of instructions in just 1–2 clock cycles due to its 3-stage pipeline and CISC Harvard architecture, making it suitable for real-time control tasks in LCD-based systems.
Does the R5F10RLCAFB#10 support LCD drive without external components?
Yes, the R5F10RLCAFB#10 integrates a full LCD controller/driver supporting up to 39 segments × 4 commons. It provides three drive methods-capacitor-split, internal voltage boost, and resistance division-and requires only external capacitors (CAPL/CAPH) and decoupling (REGC) for stable operation, eliminating the need for external driver ICs.
What low-power modes does the R5F10RLCAFB#10 offer, and what are their typical current draws?
The R5F10RLCAFB#10 supports multiple low-power states: Stop mode draws 0.23 µA (RAM retained), Halt mode draws 0.64 µA (RTC + LVD active), and operating current is 62.5 µA/MHz. These modes enable multi-year battery life in applications like utility meters and portable medical devices.
Can the R5F10RLCAFB#10 be used in industrial temperature environments?
No-the R5F10RLCAFB#10 is specified for consumer-grade operation from −40°C to +85°C (denoted by "A" in the part number). For industrial applications requiring −40°C to +105°C, select the "G" variant such as R5F10RLCGFB#10, which shares the same package and peripherals but is qualified for extended temperature range.
What communication interfaces are available on the R5F10RLCAFB#10?
The R5F10RLCAFB#10 includes one UART (7-/8-/9-bit), two CSI modules (SPI-compatible, 7-/8-bit), one IICA interface (I²C multi-master), and supports LIN protocol via UART configuration. All interfaces are accessible via configurable pins using the Peripheral I/O Redirection Register (PIOR) for flexible PCB layout.
