Product details
Overview
R5F100MHGFB#30 from Renesas is an RL78/G13 8-bit microcontroller with 128 KB flash, 12 KB RAM, and 80-pin LFQFP (0.5-mm pitch) package, operating from 1.6 V to 5.5 V across –40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates 26-channel 10-bit ADC, RTC with calendar/alarm, and ultra-low-power modes including 0.57 μA STOP mode - deployed in smart metering, industrial HMI, and battery-powered sensor nodes.
For engineers reviewing the R5F100MHGFB#30 datasheet, R5F100MHGFB#30 pinout, R5F100MHGFB#30 application, or R5F100MHGFB#30 equivalent, key selection criteria include its industrial-grade temperature rating, integrated data flash (8 KB), real-time clock with calendar function, and support for LIN-bus UART and hardware DMA - critical for deterministic low-power embedded control.
Technical Context
The R5F100MHGFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 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 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - enabling secure self-programming with boot swap and flash shield window functions.
Peripheral integration includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI (SPI-compatible) channels, and a 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor - all managed via dedicated low-power modes (HALT, STOP, SNOOZE) and on-chip LVD with 14-level voltage detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MGAFB#30 | Same 80-pin LFQFP package, but 96 KB flash / 8 KB RAM / 8 KB data flash; identical peripheral set and temperature grade. | Suitable where firmware footprint is <96 KB and less RAM is needed; lower cost for reduced memory requirements. | Select when application code size and runtime memory usage fit within 96 KB/8 KB - retains full pin and software compatibility. |
| R5F101MHAFB#30 | Same 80-pin LFQFP package and speed, but no data flash (0 KB); otherwise identical flash/RAM/peripherals/temperature rating. | Applicable where EEPROM-like nonvolatile storage is handled externally or not required; smaller die size improves yield. | Choose if data logging or field-upgradable parameters are implemented via external serial EEPROM or FRAM. |
Compared with R5F100MHGFB#30, R5F100MGAFB#30 offers memory reduction at identical industrial temperature and package, while R5F101MHAFB#30 removes data flash entirely - enabling cost optimization where persistent parameter storage is offloaded or unnecessary.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100MHGFB#30?
The R5F100MHGFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This frequency is achievable across the full industrial temperature range (–40°C to +105°C) and 1.6–5.5 V supply, with oscillator accuracy of ±1.0% under specified conditions. The R5F100MHGFB#30 maintains consistent timing behavior due to its 3-stage pipeline RL78 core and programmable instruction cycle timing.
Does the R5F100MHGFB#30 include integrated data flash memory, and what are its endurance specifications?
Yes, the R5F100MHGFB#30 includes 8 KB of on-chip data flash memory, supporting background operation (BGO) so program execution continues during writes. It guarantees 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. The data flash is organized in 1 KB blocks and supports flash shield window and block-erase prohibition for firmware security - features confirmed in the R01DS0131EJ0380 datasheet for the RL78/G13 family.
What low-power modes does the R5F100MHGFB#30 support, and what is its lowest active-current consumption?
The R5F100MHGFB#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA - the lowest active-current state. HALT mode draws 66 μA/MHz, scalable with clock frequency. All modes retain SRAM content and allow wake-up via external interrupt, RTC alarm, or comparator event. These values are measured and specified in the official RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80).
Is the R5F100MHGFB#30 pin-compatible with other RL78/G13 variants in the same 80-pin LFQFP package?
Yes, the R5F100MHGFB#30 shares identical pinout and electrical characteristics with all other RL78/G13 devices in the 80-pin LFQFP package (e.g., R5F100MGAFB#30, R5F101MHAFB#30), including identical VDD/VSS, RESET, oscillator, and I/O pin assignments. Functional differences (e.g., flash size, data flash presence) do not affect pin mapping or mechanical compatibility - verified via Renesas' official pin configuration diagrams and package drawings (PLQP0080KE-A).
What communication interfaces are integrated into the R5F100MHGFB#30, and which support LIN bus protocol?
The R5F100MHGFB#30 integrates two UART channels, three I²C/Simplified I²C channels, and two CSI (SPI-compatible) channels. One UART channel explicitly supports LIN bus protocol (LIN 2.2), including automatic checksum generation, break detection, and sync field handling - confirmed in the "Serial interface" section of the RL78/G13 datasheet. No CAN or USB interfaces are present.
