Product details
Overview
R5F100MKAFB#X0 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), and multiple serial interfaces (UART, CSI, I²C). It operates from 1.6 V to 5.5 V and delivers 41 DMIPS at 32 MHz, targeting battery-powered industrial sensors and smart metering systems.
For engineers reviewing the R5F100MKAFB#X0 datasheet, R5F100MKAFB#X0 pinout, R5F100MKAFB#X0 application, or R5F100MKAFB#X0 equivalent, key selection criteria include its 0.57 μA STOP mode current, 66 μA/MHz active power efficiency, 80-pin LFQFP 0.5-mm pitch package, and support for LIN-bus UART and background data flash rewriting.
Technical Context
The R5F100MKAFB#X0 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, real-time clock with calendar and alarm, and watchdog timer with dedicated low-speed 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.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101MKAFB#X0 | No data flash (0 KB); same core, peripherals, and package | Not suitable where nonvolatile parameter storage or firmware logging is required | Select when only code flash persistence is needed and data retention is handled externally |
| RA2A1GBGFP#AA0 | ARM Cortex-M23 core, 256 KB flash, 32 KB SRAM, 12-bit ADC (24 ch), 1.6–5.5 V | Higher performance, TrustZone security, but higher active current (110 μA/MHz) | Choose for enhanced security or ARM ecosystem compatibility; avoid if ultra-low-power STOP mode (<1 μA) is mandatory |
Compared with R5F100MKAFB#X0, R5F101MKAFB#X0 removes data flash to reduce cost and die size but retains identical real-time capability and low-power modes, while RA2A1GBGFP#AA0 trades RL78's sub-μA STOP efficiency for ARM-based scalability and security features - making R5F100MKAFB#X0 optimal for cost-sensitive, battery-constrained industrial endpoints.

Does the R5F100MKAFB#X0 support in-system programming and secure firmware updates?
Yes, the R5F100MKAFB#X0 supports full in-system programming via its on-chip debug interface and includes boot swap functionality for fail-safe firmware updates. Its flash shield window and block erase prohibition provide hardware-enforced security against unauthorized reprogramming of critical code sections.
How many analog input channels does the R5F100MKAFB#X0 support, and what is the ADC resolution?
The R5F100MKAFB#X0 integrates a 10-bit successive approximation ADC with up to 26 analog input channels (ANI0–ANI25), plus dedicated AVREFP/AVREFM pins. It also includes an internal 1.45 V reference voltage and temperature sensor - both usable in HS (high-speed main) mode.
What low-power modes are available on the R5F100MKAFB#X0, and what is the lowest current draw?
The R5F100MKAFB#X0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across the full −40°C to +105°C industrial temperature range - enabling multi-year battery operation in maintenance-free deployments.
