Product details
Overview
R5F100GKAFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, 32 MHz max CPU speed, and industrial-grade -40°C to +105°C operation. It integrates 12-bit ADC (26 channels), RTC, UART/LIN, I²C, CSI, 16-bit timers, DMA, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in HVAC, motor drives, and smart sensors.
For engineers reviewing the R5F100GKAFB#30 datasheet, R5F100GKAFB#30 pinout, R5F100GKAFB#30 application, or R5F100GKAFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, 256 KB code flash with self-programming, 12-bit ADC resolution and channel count, real-time clock calendar functionality, and support for LIN bus communication in automotive body electronics and industrial automation.
Technical Context
The R5F100GKAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 41 DMIPS at 32 MHz while supporting variable instruction execution time (0.03125 μs to 30.5 μs). Its memory subsystem includes 256 KB on-chip flash with 1 KB block erase, 8 KB data flash with background operation (BGO), and 20 KB RAM - all accessible via unified 1 MB address space.
Peripherals are tightly coupled to low-power operation: the 12-bit interval timer and RTC operate independently in STOP mode; the 12-bit ADC supports internal 1.45 V reference and temperature sensing; and serial interfaces (CSI, UART/LIN, I²C) feature configurable clock sources and interrupt-driven transfer to minimize CPU load during sensor acquisition or actuator control.

FAQ
What is the maximum operating frequency and corresponding DMIPS performance of the R5F100GKAFB#30?
The R5F100GKAFB#30 operates at up to 32 MHz with a maximum performance of 41 DMIPS. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The R5F100GKAFB#30 maintains this performance across its full industrial temperature range (-40°C to +105°C) and supply voltage (1.6–5.5 V), making it suitable for deterministic real-time control tasks in demanding environments.
Does the R5F100GKAFB#30 support LIN bus communication, and which pins are used?
Yes, the R5F100GKAFB#30 supports LIN bus communication through UART0 configured in LIN mode. Pins P30 (LINRX) and P31 (LINTX) provide dedicated LIN physical layer signaling compliant with ISO 17987-4. These pins support automatic sync byte detection, checksum calculation, and sleep/wake frame handling-enabling seamless integration into automotive body electronics networks without external transceivers.
What is the size and endurance of the data flash memory in the R5F100GKAFB#30?
The R5F100GKAFB#30 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash while data flash is being rewritten. The R5F100GKAFB#30 allocates flash library RAM starting at address FAF00H, ensuring safe self-programming during runtime calibration or firmware updates.
How many analog input channels does the 12-bit ADC in the R5F100GKAFB#30 support, and what reference options are available?
The R5F100GKAFB#30 features a 12-bit successive-approximation ADC with up to 26 analog input channels. Reference options include external AVREFP/AVREFM pins, internal 1.45 V reference (selectable only in HS mode), and VDD as reference. The integrated temperature sensor connects directly to the ADC, enabling on-die thermal monitoring without external components-critical for thermal management in motor drives and power supplies.
What low-power modes are available on the R5F100GKAFB#30, and what is the lowest achievable current consumption?
The R5F100GKAFB#30 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables decade-long battery life in wireless sensor nodes and energy-harvesting applications. All modes retain RAM content and support wake-up via external interrupt, RTC alarm, or LVD event-ensuring responsive recovery from deep sleep.
