Product details
Overview
R5F101GADFB#30 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. 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 hardware multiplier/divider for industrial control and sensor interface applications.
For engineers reviewing the R5F101GADFB#30 datasheet, R5F101GADFB#30 pinout, R5F101GADFB#30 application, or R5F101GADFB#30 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +85°C), absence of on-chip data flash (R5F101x series), LFQFP-48 7×7 mm 0.5-mm pitch package, and support for SNOOZE mode, background data flash rewriting, and LIN bus communication.
Technical Context
The R5F101GADFB#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 includes 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 targets embedded real-time control: 16-bit timer array (12 channels), 12-bit interval timer, calendar RTC with alarm/correction, 10-bit ADC with internal 1.45 V reference and temperature sensor, and three serial interfaces-CSI (SPI-compatible), UART/LIN, and I²C-with configurable channel counts per variant.

FAQ
What is the maximum operating frequency and performance of the R5F101GADFB#30?
The R5F101GADFB#30 operates up to 32 MHz and delivers 41 DMIPS of processing performance. Its RL78 CPU core uses a 3-stage pipeline and supports variable instruction timing - from 0.03125 μs at full speed to 30.5 μs in ultra-low-speed mode - enabling precise trade-offs between throughput and power consumption in the R5F101GADFB#30.
Does the R5F101GADFB#30 include on-chip data flash memory?
No, the R5F101GADFB#30 does not include on-chip data flash memory. As indicated by the "101" in its part number (per Renesas documentation), it belongs to the no-data-flash variant of the RL78/G13 family. The R5F101GADFB#30 provides 128 KB code flash and 12 KB RAM only, distinguishing it from R5F100x variants that integrate 4–8 KB of data flash.
What package type and pin count does the R5F101GADFB#30 use?
The R5F101GADFB#30 uses a 48-pin LFQFP 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 variant, and the "#30" indicates tray packaging. This package is RoHS-compliant and rated for industrial temperature operation (−40°C to +85°C).
Which serial communication protocols are supported by the R5F101GADFB#30?
The R5F101GADFB#30 supports CSI (SPI-compatible), UART/LIN, and I²C interfaces. It provides up to 8 CSI channels, 4 UART/LIN channels (with full LIN 2.2A compliance), and 10 I²C channels. These are implemented in hardware with independent clock sources and DMA support, allowing concurrent operation without CPU overhead in the R5F101GADFB#30.
What is the operating voltage range and low-power capability of the R5F101GADFB#30?
The R5F101GADFB#30 operates from 1.6 V to 5.5 V and achieves 66 μA/MHz active current. In STOP mode with RTC and LVD active, it consumes just 0.57 μA - verified across the full −40°C to +85°C industrial temperature range. This makes the R5F101GADFB#30 suitable for battery-backed or energy-harvesting applications requiring multi-year runtime.
