Product details
Overview
R5F100GLAFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GLAFB#V0 datasheet, R5F100GLAFB#V0 pinout, R5F100GLAFB#V0 application, or R5F100GLAFB#V0 equivalent, key selection considerations include its -40°C to +105°C industrial temperature grade (G suffix), 48-pin 7×7 mm 0.5-mm-pitch LFQFP package (FB), on-chip debug support, and self-programming flash with boot swap capability for field firmware updates.
Technical Context
The R5F100GLAFB#V0 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 ultra-low-speed mode). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Peripherals include 8-channel 16-bit timers, 1-channel 12-bit interval timer, 1-channel calendar RTC with alarm/correction, 2–4 channel DMA controller, and mixed-signal resources: 10-bit A/D converter with internal 1.45 V reference and temperature sensor, plus 26 analog input channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GLAFP#V0 | Same core, memory, and peripherals; packaged in 48-pin LQFP (0.65-mm pitch, FP suffix) instead of LFQFP (0.5-mm pitch, FB). | Larger footprint and lower pin density; preferred where board assembly uses standard QFP reflow profiles. | Select R5F100GLAFP#V0 when legacy PCB layout or pick-and-place tooling favors 0.65-mm pitch. |
| R5F101GLAFB#V0 | Identical package and pinout; omits 8 KB data flash and BGO functionality - reduces cost and die size. | Suitable for fixed-parameter applications without field-updatable calibration or event logging. | Choose R5F101GLAFB#V0 only if data flash persistence and background rewriting are unnecessary. |
Compared with R5F100GLAFP#V0, the R5F100GLAFB#V0 offers higher board density and thermal performance due to finer pitch and smaller footprint; versus R5F101GLAFB#V0, it adds critical nonvolatile parameter storage and runtime firmware update capability essential for certified industrial devices.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GLAFB#V0?
The R5F100GLAFB#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core efficiency under typical compiler-optimized code execution, enabling responsive real-time control in applications such as motor drives and protocol stacks without requiring external acceleration.
Does the R5F100GLAFB#V0 support on-chip debug, and what interface does it use?
Yes, the R5F100GLAFB#V0 includes full on-chip debug functionality accessible via Renesas' single-wire debug interface (SWD), compatible with E2 studio and CS+ development environments. This eliminates the need for external JTAG adapters and enables real-time breakpoints, register inspection, and flash programming during development and field service.
What are the flash memory capacities and endurance specifications for the R5F100GLAFB#V0?
The R5F100GLAFB#V0 integrates 128 KB of code flash memory and 8 KB of data flash memory. The data flash supports 1,000,000 write/erase cycles (typical) and operates across the full VDD range of 1.8–5.5 V, enabling reliable parameter storage and firmware update logging in harsh industrial environments.
How does the R5F100GLAFB#V0 achieve ultra-low power consumption in STOP mode?
The R5F100GLAFB#V0 achieves 0.57 μA STOP mode current by powering down the CPU, flash, and most peripherals while retaining RAM content and enabling only the real-time clock (RTC) and low-voltage detector (LVD). Wake-up occurs via external interrupt, RTC alarm, or LVD threshold crossing - ideal for periodic sensor sampling.
Is the R5F100GLAFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin LFQFP (FB) package share identical pinouts, including R5F100GLAFB#V0, R5F100FLAFB#V0, and R5F101GLAFB#V0. This allows hardware reuse across memory and feature variants, though software must be validated for differences in flash size, data flash presence, and peripheral enablement.
