Product details
Overview
R5F100GKAFB#X0 from Renesas is a 48-pin LFQFP (7 × 7 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 256 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6 V to 5.5 V across –40°C to +105°C. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA - deployed in smart metering, industrial sensors, and battery-powered HMI control.
For engineers reviewing the R5F100GKAFB#X0 datasheet, R5F100GKAFB#X0 pinout, R5F100GKAFB#X0 application, or R5F100GKAFB#X0 equivalent, key selection criteria include its G-grade temperature rating, on-chip data flash rewrite endurance (1M cycles), background operation capability during program execution, and support for SNOOZE mode for low-latency wake-up in energy-constrained systems.
Technical Context
The R5F100GKAFB#X0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction timing from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 256 KB code flash with 1 KB block erase granularity, 8 KB data flash supporting background operation (BGO), and 20 KB SRAM - all accessible within a unified 1 MB address space.
Peripherals are tightly coupled to low-power operation: the 10-bit ADC supports up to 26 analog inputs with internal 1.45 V reference and temperature sensor; serial interfaces include up to 8 CSI channels, 4 UART/LIN channels, and 10 I²C/Simplified I²C channels; and real-time control is enabled by 16 timer channels (including interval timer and watchdog), RTC with calendar/alarm, and 2-channel DMA with 2-clock transfer latency between SFR and RAM.

FAQ
What is the maximum operating frequency and associated performance of the R5F100GKAFB#X0?
The R5F100GKAFB#X0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS. Its RL78 CPU core supports configurable instruction timing - from 0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz - enabling dynamic trade-offs between speed and power. This makes the R5F100GKAFB#X0 suitable for both responsive control tasks and ultra-low-power monitoring modes.
Does the R5F100GKAFB#X0 support in-system programming and secure firmware updates?
Yes, the R5F100GKAFB#X0 supports full in-system programming via on-chip debug interface and includes flash security features: block erase/write prohibition, boot swap functionality, and flash shield window protection. These capabilities allow safe field firmware updates while preventing unauthorized access or corruption - essential for certified industrial deployments of the R5F100GKAFB#X0.
How does the R5F100GKAFB#X0 manage power in battery-operated applications?
The R5F100GKAFB#X0 achieves ultra-low power via multiple dedicated modes: HALT (core stopped, peripherals active), STOP (all clocks halted except RTC/LVD), and SNOOZE (peripheral-triggered wake-up with minimal latency). At 32 MHz, active current is just 66 μA/MHz; in STOP mode with RTC + LVD, it drops to 0.57 μA - directly extending battery life in remote sensor or metering applications using the R5F100GKAFB#X0.
What analog capabilities does the R5F100GKAFB#X0 provide for sensor interfacing?
The R5F100GKAFB#X0 integrates a 10-bit ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-die temperature sensor. It supports simultaneous sampling, hardware averaging, and programmable conversion triggers - enabling accurate, low-noise acquisition from resistive, capacitive, or thermistor-based sensors without external signal conditioning, a key advantage in compact designs using the R5F100GKAFB#X0.
Is the R5F100GKAFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin LFQFP (FB) package - including R5F100GKAFB#X0, R5F100FKAFB#X0, and R5F101GKAFB#X0 - share identical pinouts and electrical characteristics. This allows drop-in replacement across memory/configurations (e.g., upgrading from 96 KB to 256 KB flash) without PCB redesign - simplifying scalability and inventory management for designs based on the R5F100GKAFB#X0.
