Product details
Overview
R5F101GKDFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, and 20 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 industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F101GKDFB#V0 datasheet, R5F101GKDFB#V0 pinout, R5F101GKDFB#V0 application, or R5F101GKDFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, absence of on-chip data flash (R5F101x series), -40°C to +105°C industrial temperature grade (G suffix), and support for SNOOZE mode DMA transfers during low-power operation.
Technical Context
The R5F101GKDFB#V0 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 main system clock (up to 32 MHz) and independent low-speed subsystem clock for RTC and watchdog.
Its peripheral set includes 8–16 channels of 16-bit timers, 3–10 I²C/Simplified I²C interfaces, 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible) channels, and background operation-capable data flash rewrite - all managed via dedicated SFRs and DMA channels with 2-cycle transfer latency between SFR and RAM.

Its 20 KB RAM supports runtime variables and stack operations, and the flash library uses fixed RAM regions (e.g., FAF00H for R5F101xJ variants) for self-programming routines.
Does the R5F101GKDFB#V0 support hardware debugging?
Yes, the R5F101GKDFB#V0 includes a full on-chip debug interface compliant with Renesas E2/E2 Lite emulators. It supports real-time trace, breakpoints, watchpoints, and memory inspection without requiring external debug probes - enabling rapid firmware validation and field diagnostics directly through the single-wire debug (SWD) interface.
What is the operating temperature range for the R5F101GKDFB#V0?
The R5F101GKDFB#V0 is rated for industrial operation from -40°C to +105°C, indicated by the 'G' suffix in its part number. This extended range is validated across all specified electrical parameters, including flash write endurance, ADC accuracy, and oscillator stability, making it suitable for deployment in harsh environments such as factory automation cabinets or outdoor utility equipment.
How many ADC channels does the R5F101GKDFB#V0 support?
The R5F101GKDFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels, configurable via the ANSEL register. It supports internal reference (1.45 V), temperature sensor readout, and AVREFP/AVREFM differential reference inputs - enabling high-accuracy sensor interfacing across its full 1.6–5.5 V supply range.
Is the R5F101GKDFB#V0 pin-compatible with other RL78/G13 variants in 48-pin LFQFP?
Yes, the R5F101GKDFB#V0 shares identical pinout and package dimensions (48-pin LFQFP, 7 mm × 7 mm, 0.5 mm pitch) with all other RL78/G13 48-pin variants, including R5F100Gx and R5F101Gx families. Signal mapping, power/ground pin locations, and debug interface pins are fully aligned - enabling PCB reuse across flash-size or data-flash-enabled variants.
