Product details
Overview
R5F10RLAGFA#X0 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch), industrial-grade RL78/L12 16-bit MCU with 32 KB flash, 2 KB data flash, 1.5 KB RAM, integrated LCD controller/driver supporting up to 39 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, HVAC controllers, and portable medical devices.
For engineers reviewing the R5F10RLAGFA#X0 datasheet, R5F10RLAGFA#X0 pinout, R5F10RLAGFA#X0 application, or R5F10RLAGFA#X0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, 32 KB code flash with background data flash erase/program, 39-segment LCD drive capability, and −40°C to +105°C industrial temperature rating.
Technical Context
The R5F10RLAGFA#X0 implements the RL78 CPU core delivering 31 DMIPS at 24 MHz, with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 clock cycles. It integrates dual power domains (VDD/EVDD, VSS/EVSS) for noise-sensitive LCD applications and supports peripheral I/O redirection via PIOR register.
Its LCD controller supports three drive methods-capacitor split (0.12 µA), internal voltage boost (0.63 µA at VDD = 3.0 V), and resistance division-with 16-step contrast control, blinking, and waveform A/B selection. Real-time clock includes full calendar, alarm, and watch correction functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10RLCGFA#X0 | Same package and pinout; 32 KB flash but no LCD controller/driver | Requires external LCD driver IC; suitable for non-LCD applications needing same footprint | Select when LCD functionality is unnecessary and cost reduction via simplified BOM is prioritized |
| R5F10RGAGFB#X0 | 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch); 16 KB flash, 1 KB RAM, 35×4 or 39×4 LCD support | Smaller footprint and lower I/O count; limited to 4-common LCD configurations | Choose for space-constrained designs where 39×4 LCD resolution suffices and thermal/power budgets are tighter |
Compared with R5F10RLAGFA#X0, R5F10RLCGFA#X0 removes LCD hardware to reduce die size and cost while retaining identical packaging for layout reuse, whereas R5F10RGAGFB#X0 trades pin count and LCD flexibility for compactness and lower active current - making it suitable for smaller displays and tighter board areas.

FAQ
What is the maximum LCD segment count supported by the R5F10RLAGFA#X0?
The R5F10RLAGFA#X0 supports up to 39 segment outputs and 8 common outputs, enabling configurations such as 39 seg × 8 com or 35 seg × 8 com. This is confirmed in the RL78/L12 datasheet Section 1.6 and Figure 1-1, and applies specifically to the 64-pin variants including R5F10RLAGFA#X0.
Does the R5F10RLAGFA#X0 include an integrated RTC with calendar function?
Yes, the R5F10RLAGFA#X0 includes a full-featured real-time clock (RTC) with calendar (year/month/day/hour/minute/second), alarm, and watch correction function. The RTC operates in halt mode with only LVD enabled, consuming just 0.64 µA - a specification explicitly listed for R5F10RLAGFA#X0 in the RL78/L12 datasheet Rev.2.23.
What is the operating temperature range for the R5F10RLAGFA#X0?
The R5F10RLAGFA#X0 is rated for industrial operation from −40°C to +105°C, as indicated by the "G" suffix in the part number per Figure 1-1 of the datasheet. This distinguishes it from consumer-grade "A" variants (−40°C to +85°C) and is validated across all electrical specifications in the RL78/L12 datasheet.
Can the R5F10RLAGFA#X0 execute code while erasing or programming data flash?
Yes, the R5F10RLAGFA#X0 supports background operation of its 2 KB data flash memory. Code execution continues uninterrupted during data flash erase or program operations, enabling seamless parameter updates or firmware patching without system freeze - a feature confirmed in Section 1.1 "Data Flash Memory" of the RL78/L12 datasheet.
What package type and pitch does the R5F10RLAGFA#X0 use?
The R5F10RLAGFA#X0 uses a 64-pin plastic LQFP package measuring 12 mm × 12 mm with 0.65 mm pin pitch, as defined in Table 1-1 (Page 5) and confirmed by the "FA" package code in the part number per Figure 1-1. This matches the PLQP0064JA-A package designation in Renesas' official ordering information.
