Product details
Overview
R5F100LCAFB#V0 from Renesas is a 16-bit RL78/G13 microcontroller with 512 KB flash, 32 KB RAM, and 8 KB data flash, operating from 1.6 V to 5.5 V across -40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100LCAFB#V0 datasheet, R5F100LCAFB#V0 pinout, R5F100LCAFB#V0 application, or R5F100LCAFB#V0 equivalent, key selection criteria include its LFQFP-64 package with 0.5-mm pitch, integrated data flash for parameter storage, real-time clock with calendar/alarm, low-voltage detection with 14-level programmability, and support for background data flash rewriting during program execution.
Technical Context
The R5F100LCAFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It supports dual-clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16 × 16-bit timers, one 12-bit interval timer, one calendar-capable RTC, eight-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and three serial interface types (CSI, UART/LIN, I²C) configurable across 10 total channels - all managed via hardware DMA (4-channel controller) with 2-cycle transfers between SFR and RAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LCDFB#V0 | Same 512 KB flash, 32 KB RAM, 8 KB data flash, but D-grade (-40°C to +85°C) instead of G-grade | Suitable for commercial/industrial equipment without extended temperature requirements | Select when ambient operating temperature stays within -40°C to +85°C and cost optimization is prioritized |
| R5F101LCAFB#V0 | Identical package and pinout, but lacks data flash memory (0 KB); retains full code flash and peripheral set | Applicable where parameter storage is handled externally or not required | Choose when firmware-only operation suffices and on-chip nonvolatile parameter storage is unnecessary |
Compared with R5F100LCAFB#V0, the R5F100LCDFB#V0 offers identical performance at lower cost for standard-temperature environments, while the R5F101LCAFB#V0 removes data flash to reduce silicon area - making it viable for fixed-parameter deployments where EEPROM or external flash handles configuration.

What serial communication interfaces are integrated into the R5F100LCAFB#V0, and how are they allocated?
The R5F100LCAFB#V0 provides three serial interface types: CSI (Simplified SPI) with up to 8 channels, UART/LIN with up to 4 channels (including LIN physical layer support), and I²C/Simplified I²C with up to 10 channels. These share multiplexed pins (e.g., P10/P11) and are configured via system control registers - enabling flexible peripheral assignment in the R5F100LCAFB#V0 without external logic.
Is the R5F100LCAFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LCAFB#V0 is pin-compatible with all other RL78/G13 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F100LCDFB#V0, R5F100LCGFB#V0), sharing identical pin functions and electrical characteristics.
