Product details
Overview
R5F100LLDFB#30 from Renesas is a 64-pin LFQFP-0.5mm-pitch, industrial-grade (–40°C to +85°C) RL78/G13 16-bit MCU with 512 KB flash, 8 KB data flash, 32 KB RAM, 16-bit A/D converter (26-channel), real-time clock, and ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode). It targets battery-powered industrial control panels requiring deterministic timing, sensor fusion, and secure firmware updates.
For engineers reviewing the R5F100LLDFB#30 datasheet, R5F100LLDFB#30 pinout, R5F100LLDFB#30 application, or R5F100LLDFB#30 equivalent, key selection criteria include its 64-pin LFQFP package, integrated data flash with 1M rewrite cycles, dual SPI/I²C/UART interfaces, 16-bit timer scalability, and support for BGO during flash self-programming - critical for field-upgradable embedded systems.
Technical Context
The R5F100LLDFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz low-power mode). Its memory subsystem includes 512 KB code flash (1 KB block size), 8 KB data flash with background operation, and 32 KB SRAM - enabling simultaneous program execution and nonvolatile data logging.
Power management integrates HALT, STOP, and SNOOZE modes with on-chip POR and 14-level LVD, while peripherals include up to 26-channel 10-bit A/D, 16× 16-bit timers, 3× I²C, 4× UART (LIN-capable), and 8× CSI (SPI-compatible) channels - all configurable via register-based control without external glue logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LLAFB#30 | Same 64-pin LFQFP package and 512 KB flash, but consumer-grade (–40°C to +85°C) with no industrial qualification testing. | Limited to indoor commercial equipment; not rated for extended thermal cycling or EMI immunity in factory settings. | Select only for cost-sensitive, non-critical applications where industrial reliability certification is unnecessary. |
| R5F101LLDFB#30 | Identical pinout and package, but lacks data flash memory (0 KB) and has reduced RAM (24 KB) - no BGO or flash shield window. | Suitable for fixed-function firmware with no field update requirement; cannot store calibration data or user preferences persistently. | Choose when firmware is immutable and data logging is handled externally - reduces bill-of-materials cost by eliminating data flash overhead. |
Compared with R5F100LLDFB#30, R5F100LLAFB#30 trades industrial qualification for lower cost, while R5F101LLDFB#30 removes data flash entirely - making the R5F100LLDFB#30 the only option supporting secure, field-upgradable firmware with persistent parameter storage in industrial environments.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100LLDFB#30?
The R5F100LLDFB#30 operates at up to 32 MHz with a typical active current of 66 μA per MHz. At full speed, this yields ~2.1 mA total active current (VDD = 3.3 V), verified under TA = 25°C per R01DS0131EJ0380 Rev.3.80. Its STOP mode draws only 0.57 μA with RTC and LVD enabled - critical for battery-backed applications.
Does the R5F100LLDFB#30 support in-system programming and secure firmware updates?
Yes, the R5F100LLDFB#30 supports self-programming of both code and data flash memory with boot swap functionality and flash shield window protection. These features enable authenticated, atomic firmware updates without external programmers - a requirement for R5F100LLDFB#30 deployments in certified industrial equipment.
How many analog input channels does the R5F100LLDFB#30 provide, and what reference options are available?
The R5F100LLDFB#30 integrates a 10-bit A/D converter with up to 26 analog input channels. It supports external reference voltages or uses the internal 1.45 V reference (available only in HS mode), eliminating the need for external precision references in most sensor signal conditioning designs using R5F100LLDFB#30.
What communication interfaces are included in the R5F100LLDFB#30, and which support LIN bus physical layer compliance?
The R5F100LLDFB#30 includes up to 4 UART channels (all LIN-capable), 3 I²C interfaces, and 8 CSI channels (SPI-compatible). UART channels support LIN 2.2 physical layer timing and automatic sync-break detection - confirmed in Section 1.1 of R01DS0131EJ0380 for R5F100LLDFB#30.
Is the R5F100LLDFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 MCUs in the 64-pin LFQFP package (e.g., R5F100LLAFB#30, R5F101LLDFB#30) share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint for memory or feature scaling - provided software accounts for differences in data flash presence or RAM size in R5F100LLDFB#30.
