Product details
Overview
R5F100LKGFB#X0 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 384 KB flash, 8 KB data flash, and 24 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 - deployed in industrial motor control and smart sensor nodes.
For engineers reviewing the R5F100LKGFB#X0 datasheet, R5F100LKGFB#X0 pinout, R5F100LKGFB#X0 application, or R5F100LKGFB#X0 equivalent, key selection considerations include its -40°C to +105°C industrial temperature grade (G), 64-pin LFQFP-0.5mm pitch package, integrated data flash with background operation (BGO), and support for SNOOZE mode for low-latency wake-up in battery-powered edge devices.
Technical Context
The R5F100LKGFB#X0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 384 KB code flash (1 KB block size), 8 KB data flash with 1M write endurance, and 24 KB on-chip RAM - all accessible under single-supply 1.6–5.5 V operation.
Peripherals are tightly coupled to power management: DMA controller (4 channels), 16-bit timer array (16 channels), real-time clock with calendar/alarm, 10-bit ADC with internal 1.45 V reference and temperature sensor, and multiple serial interfaces (CSI, UART/LIN, I²C) - all configurable for low-power SNOOZE mode operation where selected peripherals remain active while CPU halts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LKAFB#X0 | Same 64-pin LFQFP package and G-grade temp range, but 256 KB flash / 20 KB RAM / 8 KB data flash | Lower memory footprint suits simpler control tasks without extensive data logging or complex UI assets | Select when application code size remains under 256 KB and RAM usage stays below 20 KB - reduces cost without sacrificing industrial qualification |
| R5F101LKAFB#X0 | Identical pinout and package, but lacks data flash (0 KB); retains same 256 KB code flash and 20 KB RAM | Eliminates BGO and flash shield window functions - unsuitable for field-updatable parameter storage | Choose only if persistent non-volatile storage is handled externally (e.g., EEPROM or FRAM) and security-critical self-programming is not required |
Compared with R5F100LKGFB#X0, the R5F100LKAFB#X0 offers reduced memory at lower cost for less demanding firmware, while the R5F101LKAFB#X0 removes data flash entirely - making it viable only when external non-volatile storage replaces on-chip data retention needs.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100LKGFB#X0?
The R5F100LKGFB#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This metric is measured under standard conditions (VDD = 3.3 V, TA = 25°C) and reflects sustained integer throughput for typical embedded control workloads - not peak burst performance.
Does the R5F100LKGFB#X0 support in-system programming and secure firmware updates?
Yes, the R5F100LKGFB#X0 supports full in-system programming via on-chip debug interface and includes flash shield window and boot swap functionality. These features allow authenticated firmware updates and prevent unauthorized access to protected code regions - critical for industrial field-deployed devices.
How many analog input channels does the R5F100LKGFB#X0 ADC support, and what reference options are available?
The R5F100LKGFB#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports external reference (AVREFP/AVREFM), internal 1.45 V reference, or VDD-based ratiometric measurement - enabling flexible sensor interfacing across voltage domains without external reference ICs.
What low-power modes are available on the R5F100LKGFB#X0, and which peripherals remain active in SNOOZE mode?
The R5F100LKGFB#X0 supports HALT, STOP, and SNOOZE modes. In SNOOZE mode, the CPU stops but selected peripherals - including UART, CSI, I²C, ADC, and 16-bit timers - continue operation under autonomous trigger conditions. Wake-up latency is under 1.5 μs, making it ideal for responsive sensor event handling.
Is the R5F100LKGFB#X0 pin-compatible with other RL78/G13 variants in the same 64-pin LFQFP package?
Yes, all RL78/G13 devices in the 64-pin LFQFP package (e.g., R5F100LKx, R5F101LKx) share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint when memory or feature requirements change - provided software is reconfigured for differences in flash size, data flash presence, or peripheral enablement.
