Product details
Overview
R5F101MGAFB#10 from Renesas is a 32-bit RL78/G13 microcontroller with 128 KB flash memory, 8 KB data flash, and 8 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 52-pin LFQFP-0.5mm package, and integrated peripherals including 10-bit ADC (26 channels), RTC, UART, I²C, and SPI - deployed in battery-powered industrial sensors and smart metering systems.
For engineers reviewing the R5F101MGAFB#10 datasheet, R5F101MGAFB#10 pinout, R5F101MGAFB#10 application, or R5F101MGAFB#10 equivalent, key selection considerations include its 52-pin LFQFP footprint, absence of on-chip data flash (R5F101x series), -40°C to +105°C industrial temperature grade (G suffix), and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F101MGAFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz) and 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable), DMA controller (4 channels), and hardware multiplier/divider for efficient signal processing.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one calendar RTC with alarm/correction, one watchdog timer, and serial interfaces: up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all configurable via register-based control without external clock dependencies.

FAQ
What is the flash memory configuration of the R5F101MGAFB#10?
The R5F101MGAFB#10 contains 128 KB of on-chip code flash memory with 1 KB erase blocks and no integrated data flash memory - consistent with the R5F101x series designation indicating data flash omission. This simplifies firmware update logic where external EEPROM or FRAM is used for parameter storage, and reduces die cost for applications not requiring embedded nonvolatile data retention.
Does the R5F101MGAFB#10 support LIN bus communication?
Yes, the R5F101MGAFB#10 supports LIN bus communication through its UART peripherals configured for LIN 2.2A and SAE J2602 compliance. It provides hardware-level LIN break detection, sync field generation, and checksum calculation, enabling reliable slave-node operation in automotive body electronics and industrial control networks without additional protocol ICs.
What is the operating temperature range for the R5F101MGAFB#10?
The R5F101MGAFB#10 is rated for industrial operation from -40°C to +105°C, indicated by the 'G' suffix in the part number. This extended temperature range ensures functional reliability in demanding environments such as smart meters installed outdoors, motor control enclosures, and under-hood automotive modules where ambient thermal stress exceeds commercial-grade limits.
How many ADC channels does the R5F101MGAFB#10 support?
The R5F101MGAFB#10 supports up to 26 analog input channels for its 10-bit successive-approximation ADC, with internal 1.45 V reference and temperature sensor. Channel mapping is flexible across port pins P20–P27, P30–P37, P40–P47, and P50–P57, allowing simultaneous sampling of voltage, current, temperature, and auxiliary signals in energy monitoring and sensor fusion applications.
What package type is used for the R5F101MGAFB#10?
The R5F101MGAFB#10 uses a 52-pin LFQFP package (7 mm × 7 mm, 0.5 mm pitch), identified by the 'FB' suffix. This fine-pitch quad flat package offers high I/O density, standard reflow compatibility, and mechanical robustness for automated assembly in industrial and automotive PCBs - distinct from QFN or BGA variants in the same RL78/G13 family.
