Product details
Overview
R5F100MGAFB#30 from Renesas is an RL78/G13 16-bit general-purpose microcontroller featuring 128 KB flash memory, 8 KB data flash, and 8 KB RAM in an 80-pin LFQFP package with 0.5-mm pitch. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F100MGAFB#30 datasheet, R5F100MGAFB#30 pinout, R5F100MGAFB#30 application, or R5F100MGAFB#30 equivalent, key selection criteria include its integrated RTC with calendar/alarm, 10-bit 26-channel ADC with internal temperature sensor, dual UART/LIN support, and hardware multiplier/divider for real-time control math.
Technical Context
The RL78 CPU core uses a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz), enabling precise trade-offs between performance and power. Its memory subsystem includes block-erasable 128 KB code flash (1 KB blocks) and background-operable 8 KB data flash supporting 1M write cycles.
Peripheral integration includes up to 16× 16-bit timers, one real-time clock with calendar and correction, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, and a DMA controller with 4 channels-enabling concurrent sensor acquisition, communication, and low-latency event handling without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGAFB#30 | 64 KB flash, 4 KB data flash, 4 KB RAM, same 80-pin LFQFP package and peripheral set. | Lower memory footprint suits simpler control tasks (e.g., basic thermostats) where full 128 KB is unnecessary. | Select when firmware size and data logging depth are constrained, and cost optimization is prioritized without sacrificing package or pin compatibility. |
| R5F101MGAFB#30 | Same 80-pin LFQFP package and peripherals, but no data flash memory (0 KB); retains 128 KB code flash and 8 KB RAM. | Targeted at applications requiring only code storage and volatile data buffering-no nonvolatile parameter retention needed. | Choose when eliminating data flash reduces qualification effort or cost, and all configuration/state data can be managed externally or in code flash. |
Compared with R5F100MGAFB#30, R5F100LGAFB#30 offers reduced memory capacity at lower cost for less complex firmware, while R5F101MGAFB#30 removes data flash entirely-simplifying programming and security models where persistent parameter storage is handled elsewhere.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100MGAFB#30?
The R5F100MGAFB#30 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. This metric reflects its RL78 CPU core's efficiency in executing instructions under typical conditions, making it suitable for real-time control tasks such as motor commutation and protocol parsing without requiring external acceleration.
Does the R5F100MGAFB#30 include an integrated temperature sensor, and how is it accessed?
Yes, the R5F100MGAFB#30 includes an on-chip temperature sensor accessible via the ADC. It is enabled only in HS (high-speed main) mode and appears as a dedicated analog input channel. Calibration data is not factory-trimmed, so system-level characterization is required for absolute accuracy-ideal for relative thermal monitoring in motor or power stage applications.
What power-saving modes are supported by the R5F100MGAFB#30, and what is the lowest achievable current draw?
The R5F100MGAFB#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only the real-time clock and low-voltage detector active, it draws just 0.57 μA. This ultra-low quiescent current enables multi-year operation on primary batteries in remote sensing and metering applications where periodic wake-up and measurement are required.
Can the R5F100MGAFB#30 perform in-system programming of its own flash memory, and what safeguards exist?
Yes, the R5F100MGAFB#30 supports self-programming of both code and data flash memory, including boot swap functionality and flash shield window protection. These features prevent unauthorized overwrite of critical firmware sections and enable secure field updates-essential for certified smart metering and industrial control deployments requiring functional safety compliance.
How many UART/LIN interfaces does the R5F100MGAFB#30 provide, and are they fully independent?
The R5F100MGAFB#30 provides two independent UART channels, each supporting LIN-bus protocol. Both channels operate concurrently with separate baud rate generators, TX/RX buffers, and interrupt resources-enabling simultaneous communication with multiple LIN slaves (e.g., sensors and actuators) in automotive body electronics or industrial distributed I/O systems.
What is the pin count and package type of the R5F100MGAFB#30, and is it RoHS compliant?
The R5F100MGAFB#30 uses an 80-pin LFQFP package with 0.5-mm pitch and 12 × 12 mm footprint. It is RoHS-compliant and rated for moisture sensitivity level 3. This package balances high I/O density with manufacturability in standard SMT lines, supporting designs requiring numerous GPIOs, analog inputs, and serial interfaces in space-constrained industrial PCBs.
