Product details
Overview
R5F100MKAFB#30 from Renesas is an RL78/G13 80-pin, 384 KB flash, 8 KB data flash, 20 KB RAM ultra-low-power 16-bit MCU with integrated RTC, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock-designed for battery-powered industrial sensors and smart metering applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100MKAFB#30 datasheet, R5F100MKAFB#30 pinout, R5F100MKAFB#30 application, or R5F100MKAFB#30 equivalent, key selection criteria include its 0.57 μA STOP-mode current, 41 DMIPS @ 32 MHz performance, LFQFP-80 (12 × 12 mm, 0.5 mm pitch) package, and support for background data flash rewriting with BGO.
Technical Context
The R5F100MKAFB#30 implements the RL78 CPU core with a 3-stage pipeline, 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, calendar-based RTC with alarm and correction, and a watchdog timer driven by a dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) channels-all configurable via register-based control without external glue logic. The DMA controller supports 4-channel transfers with 2-clock latency between SFR and internal RAM.

Yes, the R5F100MKAFB#30 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features for IP protection. Its self-programming capability enables secure firmware updates with boot swap functionality-critical for field-deployed devices requiring authenticated code upgrades. All flash operations are supported in the R5F100MKAFB#30 without external hardware.
What power modes does the R5F100MKAFB#30 offer, and what are their typical current draws?
The R5F100MKAFB#30 provides HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA; active-mode current is 66 μA/MHz. These values are measured at VDD = 3.0 V and TA = 25°C. The low-power profile makes the R5F100MKAFB#30 ideal for battery-backed applications such as utility meters and remote sensors.
Can the R5F100MKAFB#30 operate across the full industrial temperature range?
Yes, the R5F100MKAFB#30 is rated for −40°C to +105°C operation (G-grade), validated per Renesas' industrial qualification standards. This rating applies to all specified electrical characteristics, including flash endurance, ADC linearity, and oscillator stability. The R5F100MKAFB#30 is therefore qualified for under-hood automotive, factory floor, and outdoor infrastructure deployments.
How many serial communication interfaces does the R5F100MKAFB#30 integrate, and what protocols do they support?
The R5F100MKAFB#30 integrates up to 4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels. UART supports LIN 2.2 physical layer features including sync-break detection and checksum generation.
