Product details
Overview
R5F101GEAFB#30 from Renesas is a 48-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GEAFB#30 datasheet, R5F101GEAFB#30 pinout, R5F101GEAFB#30 application, or R5F101GEAFB#30 equivalent, key selection criteria include its data flash absence (vs. R5F100x series), 48-pin LFQFP package with 0.5-mm pitch, -40°C to +85°C industrial temperature grade (D), and support for background data flash rewriting under full VDD range (1.8–5.5 V).
Technical Context
The R5F101GEAFB#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 subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and DMA controller with 2 channels enabling 2-clock transfers between SFR and RAM.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock (RTC) with alarm and correction functions, and a watchdog timer operable via dedicated low-speed oscillator - all designed for deterministic timing control in resource-constrained embedded systems without external timing components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GEAFB#30 | Same package and pinout, but includes 8 KB data flash (vs. 4 KB in R5F101GEAFB#30) and 12 KB RAM (vs. 4 KB); higher power in STOP mode (1.25 μA). | Preferred where frequent non-volatile parameter updates or larger firmware overlays are required; less suitable for ultra-low-power endpoint designs. | Select R5F100GEAFB#30 only if data flash capacity >4 KB is mandatory and 0.68 μA additional STOP current is acceptable. |
| R5F101GEAFP#30 | Identical memory and peripherals, but in 48-pin LQFP-0.65mm pitch (PLQP0048KB-B) instead of LFQFP-0.5mm; same -40°C to +85°C rating. | Used where legacy PCB layouts or assembly processes require 0.65 mm pitch; incompatible with 0.5 mm pitch footprints without redesign. | Choose R5F101GEAFP#30 only for compatibility with existing 0.65 mm pitch land patterns; not a drop-in replacement for R5F101GEAFB#30. |
Compared with R5F100GEAFB#30, the R5F101GEAFB#30 trades data flash capacity and RAM size for lower STOP-mode current - optimizing for energy-constrained endpoints. Against R5F101GEAFP#30, it offers finer pitch packaging for higher-density layouts but requires updated stencil and placement tooling.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GEAFB#30?
The R5F101GEAFB#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's efficiency in executing compiled C code under typical workloads, including interrupt handling and peripheral register access - making it suitable for real-time control tasks in appliances and industrial controllers where deterministic timing is essential.
Does the R5F101GEAFB#30 include data flash memory, and what is its endurance specification?
Yes, the R5F101GEAFB#30 includes 4 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. This enables reliable storage of calibration coefficients, device configuration, and event logs without requiring external EEPROM or FRAM, reducing system BOM count and footprint.
What package type and pin pitch does the R5F101GEAFB#30 use, and is it RoHS-compliant?
The R5F101GEAFB#30 uses a 48-pin LFQFP package with 0.5 mm pin pitch (PLQP0048KF-A), measuring 7 mm × 7 mm with an exposed thermal pad. It is fully RoHS-compliant and qualified to moisture sensitivity level 3, supporting standard reflow soldering profiles without special baking requirements prior to assembly.
How does the R5F101GEAFB#30 support low-power operation in battery-powered applications?
The R5F101GEAFB#30 achieves ultra-low-power operation through multiple hardware states: HALT mode (1.2 μA), STOP mode (0.57 μA with RTC + LVD active), and SNOOZE mode (selective peripheral wake-up). Its 66 μA/MHz active current and ability to retain RAM and register context during STOP enable rapid wake-up and extended operational lifetime in energy-constrained deployments like wireless sensors.
Can the R5F101GEAFB#30 perform ADC conversions while running from internal oscillators, and what reference options are available?
Yes, the R5F101GEAFB#30 supports 10-bit ADC conversions using either the internal 1.45 V reference or external AVREFP/AVREFM inputs - all while operating from its high-accuracy ±1.0% on-chip oscillator (32 MHz down to 1 MHz). This eliminates dependency on external crystals or references for basic sensing, simplifying design and improving reliability in space- and cost-constrained applications.
