Product details
Overview
R5F101GKDFB#30 from Renesas is a 48-pin LFQFP, 5 V-tolerant 16-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, and integrated RTC, 10-bit ADC (26 channels), UART, I²C, CSI, and 16-bit timers - deployed in industrial motor control and sensor interface modules requiring low-power operation across -40°C to +105°C.
For engineers reviewing the R5F101GKDFB#30 datasheet, R5F101GKDFB#30 pinout, R5F101GKDFB#30 application, or R5F101GKDFB#30 equivalent, key selection criteria include its G-grade industrial temperature rating, absence of on-chip data flash programming capability (R5F101x series), LFQFP-48 7×7 mm 0.5-mm pitch package, and support for SNOOZE mode wake-up via serial interface interrupts.
Technical Context
The R5F101GKDFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer operating independently on the dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 16 channels of 16-bit timer, 3–10 channels of I²C/Simplified I²C, 2–4 UART/LIN channels, 2–8 CSI channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all configurable under HALT, STOP, and SNOOZE low-power modes with 0.57 μA RTC+LVD retention current.

The R5F101GKDFB#30 operates at up to 32 MHz using the high-speed on-chip oscillator. Its minimum instruction execution time is 0.03125 μs at this frequency, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. The oscillator accuracy is ±1.0% across -20°C to +85°C ambient conditions.
Does the R5F101GKDFB#30 include on-chip data flash memory?
No, the R5F101GKDFB#30 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number per Renesas documentation, this variant provides only code flash (256 KB) and 20 KB RAM. For data flash capability, consider the R5F100GKDFB#30, which includes 4 KB of data flash.
What package type and dimensions does the R5F101GKDFB#30 use?
The R5F101GKDFB#30 uses a 48-pin LFQFP package (PLQP0048KB-B) with 7 mm × 7 mm body size and 0.5 mm pin pitch. It features an exposed thermal pad on the underside and complies with RoHS and lead-free requirements. This fine-pitch package supports high-density industrial PCB layouts.
What industrial temperature grade does the R5F101GKDFB#30 support?
The R5F101GKDFB#30 is rated for industrial operation from -40°C to +105°C, denoted by the "G" suffix in its part number. This qualifies it for deployment in demanding environments such as motor drives, factory automation controllers, and outdoor metering equipment without derating.
Which serial interfaces are supported by the R5F101GKDFB#30?
The R5F101GKDFB#30 supports three serial interface types: Simplified SPI (CSI) with 2–8 channels, UART/LIN with 2–4 channels, and I²C/Simplified I²C with 3–10 channels.
