Product details
Overview
R5F101GKAFB#30 from Renesas is a 48-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 256 KB flash, 8 KB data flash, 20 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart metering, industrial sensors, and battery-powered HMI control units.
For engineers reviewing the R5F101GKAFB#30 datasheet, R5F101GKAFB#30 pinout, R5F101GKAFB#30 application, or R5F101GKAFB#30 equivalent, key selection criteria include its data flash absence (vs. R5F100x variants), G-grade temperature range (−40°C to +105°C), LFQFP-48 package with 0.5 mm pitch, and full peripheral set including BGO-capable data flash rewrite and hardware multiplier/divider.
Technical Context
The R5F101GKAFB#30 implements the RL78 CPU core with 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory subsystem includes 256 KB on-chip code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 20 KB RAM - all accessible within a 1 MB address space.
Peripheral integration centers on low-power system control: dual UART/LIN interfaces, up to 10 I²C channels, 8 CSI/SPI channels, 16× 16-bit timers (including calendar RTC with alarm and correction), 10-bit ADC with internal 1.45 V reference and temperature sensor, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F101GKAFB#30?
The R5F101GKAFB#30 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) under standard test conditions. This performance level supports real-time protocol stacks (e.g., Modbus RTU over UART), sensor fusion algorithms, and responsive HMI rendering - all while maintaining the RL78/G13's hallmark ultra-low-power profile. The core achieves this via a 3-stage pipeline and optimized instruction set.
Does the R5F101GKAFB#30 include on-chip data flash memory?
No, the R5F101GKAFB#30 does not include on-chip data flash memory. Per Renesas part numbering convention, the "101" prefix indicates data flash omission, distinguishing it from "100"-series variants like R5F100GKAFB#30 which integrate 4 KB or 8 KB data flash. All R5F101x devices rely solely on code flash for nonvolatile storage unless external EEPROM or FRAM is used.
What package type and pin pitch does the R5F101GKAFB#30 use?
The R5F101GKAFB#30 uses a 48-pin LFQFP (Low-profile Fine-pitch Quad Flat Package) with 7 mm × 7 mm body size and 0.5 mm pin pitch. This package is RoHS-compliant and rated for moisture sensitivity level 3 (MSL3), requiring bake conditioning before reflow if exposed beyond floor life. The #30 suffix denotes tray packaging per Renesas standard.
What is the operating temperature range specified for the R5F101GKAFB#30?
The R5F101GKAFB#30 is rated for industrial operation from −40°C to +105°C (G-grade). This extended range qualifies it for under-hood automotive applications, factory-floor sensor nodes, and outdoor utility equipment - unlike A-grade (−40°C to +85°C) or D-grade (−40°C to +85°C, industrial) variants. Thermal performance is validated across this full span per JEDEC JESD22-A104.
Which communication interfaces are integrated into the R5F101GKAFB#30?
The R5F101GKAFB#30 integrates UART (up to 4 channels, LIN-capable), I²C (up to 10 channels, including simplified mode), and CSI (Renesas' SPI-compatible interface, up to 8 channels). These interfaces support concurrent operation - e.g., UART for host communication, I²C for sensor reading, and CSI for display update - with shared pin resources managed via flexible peripheral function select registers.
