Product details
Overview
R5F101GAAFB#70 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 from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), and integrated real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GAAFB#70 datasheet, R5F101GAAFB#70 pinout, R5F101GAAFB#70 application, or R5F101GAAFB#70 equivalent, key selection criteria include its data flash absence (vs. R5F100x variants), industrial-grade temperature range (−40°C to +105°C), LFQFP-48 0.5-mm pitch package, and support for LIN bus via UART peripherals.
Technical Context
The R5F101GAAFB#70 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 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 DMA channels, and serial interfaces: 2–8 CSI (SPI-compatible), 2–4 UART/LIN, and 3–10 I²C channels - all configurable without external components for embedded control consolidation.
Key Specifications

FAQ
What is the maximum operating frequency and performance of the R5F101GAAFB#70?
The R5F101GAAFB#70 operates at up to 32 MHz with a performance rating of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline CISC architecture, with minimum instruction execution time adjustable from 0.03125 μs (high-speed mode) to 30.5 μs (subsystem clock mode). This balance of speed and efficiency makes the R5F101GAAFB#70 well-suited for real-time control tasks in constrained environments.
Does the R5F101GAAFB#70 include data flash memory?
No, the R5F101GAAFB#70 does not include data flash memory. As indicated by the "101" prefix in its part number (per Renesas documentation), it belongs to the data-flash-free variant family. In contrast, "100"-series parts like R5F100GAAFB#70 integrate 8 KB of data flash. Designers using the R5F101GAAFB#70 must implement external nonvolatile storage (e.g., EEPROM or FRAM) for configuration or logging data.
What package type and pin count does the R5F101GAAFB#70 use?
The R5F101GAAFB#70 uses a 48-pin LFQFP (Low-profile Fine-pitch Quad Flat Package) with 7 mm × 7 mm body size and 0.5 mm pin pitch. The "FB" suffix in the part number explicitly denotes this LFQFP package per Renesas' naming convention. This package supports reflow soldering, offers good thermal dissipation, and is compatible with standard automated assembly processes.
What is the operating temperature range for the R5F101GAAFB#70?
The R5F101GAAFB#70 is rated for an industrial operating ambient temperature range of −40°C to +105°C, denoted by the "G" grade in its part number. This specification qualifies it for deployment in demanding environments such as under-hood automotive modules, factory automation controllers, and outdoor utility infrastructure - where thermal stability and long-term reliability are critical.
Which serial communication interfaces are supported by the R5F101GAAFB#70?
The R5F101GAAFB#70 supports three primary serial interfaces: Simplified SPI (CSI) with 2–8 channels, UART/LIN with 2–4 channels (including LIN 2.1/2.2 frame support), and I²C/Simplified I²C with 3–10 channels. These interfaces are fully configurable in software and share pins via multiplexing - enabling flexible peripheral connectivity without external level shifters or protocol translators.
