Product details
Overview
R5F101GDAFB#30 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit 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 real-time clock with calendar function - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101GDAFB#30 datasheet, R5F101GDAFB#30 pinout, R5F101GDAFB#30 application, or R5F101GDAFB#30 equivalent, key selection considerations include its data flash absence (vs. R5F100x series), -40°C to +105°C industrial temperature grade (G suffix), LFQFP-48 package (0.5 mm pitch), and integrated peripherals including UART/LIN, I²C, CSI, and DMA for deterministic low-power embedded control.
Technical Context
The R5F101GDAFB#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 a 12-bit interval timer, 16-bit timers (12 channels), watchdog timer, and real-time clock with calendar, alarm, and clock correction functions.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and LVD (14 selectable levels), and background operation for data flash rewriting. Serial interfaces comprise up to 8 CSI channels, 4 UART/LIN channels, and 10 I²C/Simplified I²C channels - all configurable without external transceivers.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GDAFB#30?
The R5F101GDAFB#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects integer instruction throughput under typical conditions using the RL78 core's 3-stage pipeline and optimized compiler toolchain - enabling responsive real-time control in applications like motor commutation and sensor sampling loops.
Does the R5F101GDAFB#30 include data flash memory, and how does it differ from the R5F100x series?
No, the R5F101GDAFB#30 does not include data flash memory - the "1" in the part number explicitly denotes data flash omission per Renesas' naming convention. In contrast, the R5F100GDAFB#30 variant includes 4 KB of data flash for EEPROM emulation. This makes R5F101GDAFB#30 ideal for applications where nonvolatile parameter storage is handled externally or unnecessary.
What industrial temperature range is supported by the R5F101GDAFB#30, and how is this indicated in the part number?
The R5F101GDAFB#30 supports an operating ambient temperature range of -40°C to +105°C, certified for industrial applications. This is encoded in the "G" suffix of the part number per Renesas' RL78/G13 ordering guide - distinguishing it from "A" (-40°C to +85°C, consumer) and "D" (-40°C to +85°C, industrial) variants.
Which package type and footprint does the R5F101GDAFB#30 use, and what are its mechanical dimensions?
The R5F101GDAFB#30 uses a 48-pin LFQFP package (lead-free, RoHS-compliant) with 7 mm × 7 mm body size and 0.5 mm pin pitch. Its standardized footprint aligns with JEDEC MS-026, enabling drop-in compatibility with existing LFQFP-48 layouts and supporting automated optical inspection and reflow soldering in high-volume manufacturing.
Can the R5F101GDAFB#30 operate from a single 1.8 V supply, and what are the implications for peripheral functionality?
Yes, the R5F101GDAFB#30 supports operation from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, the maximum clock frequency is reduced to 16 MHz per datasheet specifications, and analog features such as the 10-bit ADC retain full functionality with adjusted reference scaling - enabling ultra-low-voltage operation in coin-cell or energy-harvesting systems without sacrificing precision.
