Product details
Overview
R5F10RLAGFA#30 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch), industrial-grade RL78/L12 16-bit 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 display systems such as smart meters and industrial HMI panels.
For engineers reviewing the R5F10RLAGFA#30 datasheet, R5F10RLAGFA#30 pinout, R5F10RLAGFA#30 application, or R5F10RLAGFA#30 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, 32 KB code flash with background data flash erase/program, 10-bit ADC with internal reference, and dual-clock domain support for simultaneous high-speed (24 MHz) and low-power (32.768 kHz) operation.
Technical Context
The R5F10RLAGFA#30 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and CISC instruction set delivering 31 DMIPS at 24 MHz. Its on-chip voltage regulator supports 1.6 V–5.5 V single-supply operation, enabling direct integration into wide-input industrial power rails.
It integrates a full-featured LCD controller supporting capacitor split, internal boost, and resistance division drive methods with 16-step contrast control and blinking function. The peripheral set includes UART, I²C, two CSI (SPI-compatible) interfaces, RTC with calendar/alarm, and 8-channel 16-bit timer array - all accessible via configurable I/O redirection registers (PIOR).

FAQ
What is the maximum operating frequency and performance of the R5F10RLAGFA#30?
The R5F10RLAGFA#30 operates at up to 24 MHz using its high-speed on-chip oscillator with ±1% accuracy across 1.8–5.5 V and −20°C to +85°C. It delivers 31 DMIPS of processing performance, and 86% of instructions execute in just 1–2 clock cycles due to its optimized 3-stage pipeline and CISC architecture.
Does the R5F10RLAGFA#30 support external crystal oscillators for both main and subsystem clocks?
Yes, the R5F10RLAGFA#30 supports external crystals on both domains: P121/P122 accept a 1–20 MHz crystal for the main system clock (X1/X2), while P123/P124 accept a 32.768 kHz crystal for the subsystem clock (XT1/XT2), enabling precise RTC operation independent of main CPU activity.
How many LCD segments and commons does the R5F10RLAGFA#30 support, and what drive methods are available?
The R5F10RLAGFA#30 supports up to 39 segment outputs (SEG0–SEG38) and 8 common outputs (COM0–COM7), configurable for 35×8 or 39×4 multiplexing. It supports three LCD drive methods: capacitor split (0.12 µA), internal voltage boost (0.63 µA @ 3.0 V), and external resistance division - selectable per application requirements.
What safety certifications or built-in functional safety features does the R5F10RLAGFA#30 include?
The R5F10RLAGFA#30 includes hardware-level safety features compliant with IEC/UL 60730, including flash memory CRC calculation, RAM parity error detection, SFR and RAM write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test - enabling certified Class B safety implementations without external supervision circuitry.
Is the R5F10RLAGFA#30 pin-compatible with other RL78/L12 variants in the same package?
Yes, all RL78/L12 devices in the 64-pin LQFP-0.65mm package (e.g., R5F10RLAxx, R5F10RLCxx) share identical pinouts and electrical characteristics. The R5F10RLAGFA#30 is fully pin-compatible with R5F10RLCGFA#30 and R5F10RLAAGFA#30, differing only in flash size (32 KB), data flash (2 KB), and industrial temperature rating (−40°C to +105°C).
