Product details
Overview
R5F101GHAFB#10 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 12 KB RAM, and no data flash memory, 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 R5F101GHAFB#10 datasheet, R5F101GHAFB#10 pinout, R5F101GHAFB#10 application, or R5F101GHAFB#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, absence of on-chip data flash, industrial-grade -40°C to +105°C operation (G-grade), and support for background data flash programming via external library when used with compatible variants.
Technical Context
The R5F101GHAFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and supports multiple low-power modes with independent peripheral clock gating.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one calendar RTC with alarm/correction, one watchdog timer, two DMA channels, and serial interfaces: up to four UART/LIN channels, up to ten I²C/Simplified I²C channels, and up to eight CSI (SPI-compatible) channels - all accessible within its 48-pin LFQFP footprint.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GHAFB#10?
The R5F101GHAFB#10 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The R5F101GHAFB#10 maintains this performance across its full 1.6 V to 5.5 V supply range and -40°C to +105°C temperature envelope, making it suitable for deterministic real-time control tasks in industrial environments.
Does the R5F101GHAFB#10 include on-chip data flash memory?
No, the R5F101GHAFB#10 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number per Renesas' naming convention, this variant provides only code flash (128 KB) and SRAM (12 KB). Applications requiring nonvolatile parameter storage must use external EEPROM or serial flash, or select the R5F100GHAFB#10 variant which includes 8 KB of data flash.
What package type and pin pitch does the R5F101GHAFB#10 use?
The R5F101GHAFB#10 uses a 48-pin LFQFP package with 7 mm × 7 mm body size and 0.5 mm pin pitch. Its ordering suffix "FB" explicitly denotes LFQFP-0.5 mm pitch per Renesas' package coding. This package is compatible with standard surface-mount assembly processes, including reflow soldering and automated optical inspection, and supports fine-pitch routing on 4-layer PCBs.
What is the operating temperature grade of the R5F101GHAFB#10?
The R5F101GHAFB#10 is rated for industrial operation from -40°C to +105°C, denoted by the "G" suffix in its part number. This grade qualifies it for deployment in harsh environments such as motor drives, outdoor utility meters, and factory-floor controllers where ambient temperatures exceed commercial-grade limits. The device maintains full specification compliance across this entire range.
Which serial communication interfaces are supported by the R5F101GHAFB#10?
The R5F101GHAFB#10 supports UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible, up to 8 channels), all implemented in hardware with independent registers and interrupt vectors. These interfaces share pins flexibly - for example, P10–P13 can be configured as SCK00/SI00/SO00/SS00 (CSI) or SCL00/SDA00/RxD0/TxD0 (I²C/UART) - enabling compact, multi-protocol peripheral connectivity.
