Product details
Overview
R5F100MGAFB#10 from Renesas is an RL78/G13 80-pin, 96 KB flash, 8 KB data flash, 8 KB RAM ultra-low-power 16-bit MCU with integrated RTC, 10-bit ADC (26 channels), and multiple serial interfaces (UART, I²C, CSI). It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and targets battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F100MGAFB#10 datasheet, R5F100MGAFB#10 pinout, R5F100MGAFB#10 application, or R5F100MGAFB#10 equivalent, key selection criteria include its LFQFP-80 (0.5 mm pitch) package, -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, and BGO-capable data flash for firmware updates without halting execution.
Technical Context
The R5F100MGAFB#10 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 ultra-low-speed mode). It integrates a 12-bit interval timer, real-time clock with calendar and alarm, and watchdog timer powered by a 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 logic without external glue logic.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101MGAFB#10 | No data flash (0 KB); otherwise identical core/peripherals/package. | Not suitable where field-upgradable parameters or event logging is required. | Select only if firmware is fully static and no runtime configuration persistence is needed. |
| STM32F072RBT6 | ARM Cortex-M0+, 128 KB flash, 16 KB RAM, no integrated RTC calendar; requires external crystal for full accuracy. | Better suited for USB-CDC or higher-throughput control; lacks ultra-low-power STOP mode with RTC. | Choose when ARM ecosystem tooling or USB connectivity outweighs power and RTC advantages. |
Compared with R5F101MGAFB#10 and STM32F072RBT6, the R5F100MGAFB#10 uniquely balances ultra-low-power operation (0.57 μA RTC mode), integrated calendar RTC, and BGO data flash - making it optimal for long-life, time-aware embedded systems where ARM overhead or external timing components are undesirable.

FAQ
What is the maximum operating frequency and performance rating of the R5F100MGAFB#10?
The R5F100MGAFB#10 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) performance. Its RL78 CPU core features a 3-stage pipeline and supports variable instruction execution times - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed mode - enabling precise trade-offs between throughput and power consumption in the R5F100MGAFB#10 design.
Does the R5F100MGAFB#10 include on-chip debug capability?
Yes, the R5F100MGAFB#10 includes full on-chip debug functionality via the single-wire debug interface (SWD), supporting breakpoints, watchpoints, and real-time memory inspection. Pins P30 (TOOLRST) and P11 (TOOLRxD) are dedicated to debug reset and receive, enabling in-circuit programming and non-intrusive debugging without halting real-time operation of the R5F100MGAFB#10.
What are the data flash endurance and rewrite voltage specifications for the R5F100MGAFB#10?
The R5F100MGAFB#10 provides 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) and supports rewrites across the full operating voltage range of VDD = 1.8 V to 5.5 V. This allows reliable parameter storage and firmware update staging even under brown-out conditions - a key reliability feature built into the R5F100MGAFB#10 architecture.
How does the R5F100MGAFB#10 support low-power operation in battery-powered systems?
The R5F100MGAFB#10 achieves ultra-low-power operation via HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode for peripheral-triggered wake-up. Its integrated RTC maintains calendar time and alarms in STOP mode, and the 1.6 V minimum supply enables direct use with single-cell lithium batteries - critical for extending operational life in remote R5F100MGAFB#10 deployments.
Is the R5F100MGAFB#10 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100MGAFB#10 is pin-compatible with all other RL78/G13 devices in the 80-pin LFQFP-0.5mm package (e.g., R5F100MFAFB#10, R5F100MHAFB#10), sharing identical pin functions and electrical characteristics. This allows hardware reuse across memory/configurations - for example, upgrading from 64 KB to 96 KB flash without PCB changes - while maintaining full compatibility with the R5F100MGAFB#10 footprint and signal routing.
