For engineers reviewing the R5F100GKDFB#10 datasheet, R5F100GKDFB#10 pinout, R5F100GKDFB#10 application, or R5F100GKDFB#10 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), LFQFP-48 7×7 mm 0.5-mm pitch package, on-chip debug support, self-programmable flash with boot swap, and real-time clock with calendar/alarm functions.
Technical Context
The R5F100GKDFB#10 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, real-time clock with 99-year calendar, watchdog timer, and DMA controller with 4 channels for efficient peripheral-to-memory transfers.
Its power management includes on-chip POR and LVD with 14 selectable voltage detection levels, HALT/STOP/SNOOZE low-power modes, and a high-accuracy ±1.0% on-chip oscillator (32 MHz to 1 MHz).

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GKDFB#10?
The R5F100GKDFB#10 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8 V to 5.5 V and -40°C to +105°C. The RL78 core's 3-stage pipeline and optimized instruction set deliver consistent throughput for real-time control tasks without requiring external clock sources.
Does the R5F100GKDFB#10 include on-chip debug capability and what interface does it use?
Yes, the R5F100GKDFB#10 includes full on-chip debug functionality accessible via the single-wire debug (SWD) interface using the TOOLRxD and TOOLTxD pins. This enables non-intrusive breakpoints, register inspection, and flash programming without halting real-time peripherals - critical for validating motor control timing and sensor acquisition sequences in the R5F100GKDFB#10.
What are the data flash endurance and voltage requirements for rewriting the R5F100GKDFB#10?
The R5F100GKDFB#10 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows program execution from code flash while rewriting data flash - ensuring deterministic latency for time-critical tasks in the R5F100GKDFB#10.
How many analog input channels does the R5F100GKDFB#10 support and what reference options are available?
The R5F100GKDFB#10 integrates a 10-bit successive approximation ADC with 24 configurable analog input channels. It supports external reference voltages on AVREFP/AVREFM pins and includes an internal 1.45 V reference. The internal reference is selectable only in HS (high-speed main) mode and enables accurate ratiometric measurements without external precision references in the R5F100GKDFB#10.
Is the R5F100GKDFB#10 qualified for automotive applications and what temperature grade does it carry?
The R5F100GKDFB#10 carries the 'G' suffix indicating Industrial temperature grade (-40°C to +105°C), which meets AEC-Q100 stress test requirements for many under-hood and cabin applications. While not officially AEC-Q100 certified out-of-box, its qualification envelope and built-in LVD/watchdog make it widely adopted in automotive body control modules - confirmed in Renesas' RL78/G13 automotive reference designs for the R5F100GKDFB#10.
