Product details
Overview
R5F100MHGFB#70 from Renesas is an RL78/G13 80-pin, 5V-tolerant 16-bit microcontroller with 128 KB flash, 12 KB RAM, and integrated 10-bit ADC (26 channels), RTC, and low-power STOP/HALT modes. It operates from 1.6–5.5 V, delivers 41 DMIPS at 32 MHz, and targets battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F100MHGFB#70 datasheet, R5F100MHGFB#70 pinout, R5F100MHGFB#70 application, or R5F100MHGFB#70 equivalent, key selection criteria include its 80-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature grade (G-suffix), on-chip data flash (8 KB), and support for UART/LIN, I²C, and CSI serial interfaces in space-constrained embedded systems.
Technical Context
The R5F100MHGFB#70 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-power mode). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and a watchdog timer driven by a dedicated low-speed oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, 2–8-channel CSI, and DMA controller with 4 channels - enabling deterministic timing control and background data movement without CPU intervention in mixed-signal industrial firmware.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100MHGFB#70?
The R5F100MHGFB#70 operates at up to 32 MHz with 41 DMIPS performance and consumes 66 μA per MHz in active mode. At full speed, typical active current is ~2.1 mA (32 MHz × 66 μA/MHz), verified under VDD = 3.3 V, TA = 25°C conditions per R01DS0131EJ0380.
Does the R5F100MHGFB#70 support LIN bus communication, and how is it implemented?
Yes, the R5F100MHGFB#70 supports LIN 2.2/2.2A via UART0 with dedicated hardware features including automatic break detection, sync field generation, and checksum calculation. This eliminates software overhead and ensures reliable frame timing compliance in automotive body electronics applications.
What is the endurance and retention specification for the on-chip data flash in the R5F100MHGFB#70?
The R5F100MHGFB#70 includes 8 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) and 20-year data retention at 85°C. It supports background operation (BGO), allowing program execution from main flash while rewriting data flash sectors.
How does the R5F100MHGFB#70 achieve ultra-low power consumption in STOP mode?
The R5F100MHGFB#70 achieves 0.57 μA in STOP mode by disabling the CPU, flash, and most peripherals while retaining RTC operation, low-voltage detector (LVD), and RAM contents. The dedicated 32.768 kHz subsystem clock and LVD circuit remain powered, enabling wake-up on alarm or voltage threshold breach.
Is the R5F100MHGFB#70 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 80-pin LFQFP-0.5mm package (FB suffix) share identical pinouts, including R5F100MHGFB#70, R5F100MLGFB#70, and R5F101MHGFB#70. Function allocation per pin is consistent; only memory size and data flash presence differ across variants.
