Product details
Overview
R5F101MGAFB#V0 from Renesas is an RL78/G13 16-bit microcontroller with 128 KB flash memory, 8 KB data flash, and 12 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-0.5 mm package, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101MGAFB#V0 datasheet, R5F101MGAFB#V0 pinout, R5F101MGAFB#V0 application, or R5F101MGAFB#V0 equivalent, key selection criteria include its data flash absence (vs. R5F100x variants), industrial-grade temperature range (−40°C to +105°C), LFQFP-52 pin count and 0.5-mm pitch, and support for background data flash rewriting with BGO.
Technical Context
The R5F101MGAFB#V0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates a dedicated low-speed on-chip oscillator for watchdog and RTC operation independent of main system clock.
Its peripheral set includes 16 × 16-bit timer channels, one 12-bit interval timer, calendar-based RTC with alarm and correction, 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and three serial interface types (CSI, UART/LIN, I²C) configurable across up to 10 total channels - all managed via register-level control without external clock dependencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and compact code footprint. |
| Max Operating Frequency | 32 MHz (41 DMIPS); delivers sufficient throughput for sensor fusion and protocol stack execution in edge nodes. |
| Flash Memory | 128 KB code flash; supports secure block erase prohibition and self-programming with boot swap. |
| Data Flash | None (R5F101x series); eliminates need for flash shield window management but requires external NV storage for logging. |

| Power Consumption | 66 μA/MHz active; 0.57 μA in STOP mode with RTC + LVD; enables multi-year battery life in periodic wake-up applications. |
| ADC Resolution & Channels | 10-bit resolution, 26 analog inputs; supports simultaneous monitoring of multiple sensors (voltage, temp, current) without external mux. |
| Operating Temperature | −40°C to +105°C (G-grade); qualified for under-hood automotive modules and industrial motor drives. |
Pinout & Package
Package: 52-pin LFQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10/SCK00/SCL00 | Serial Clock Input/Output | Shared SPI clock (CSI) and I²C clock; enables dual-protocol use on same pin with software-configurable function. |
| P11/SI00/RxD0/TOOLRxD/SDA00 | Serial Data Input / UART RX / I²C Data | Multi-function pin supporting SPI input, UART receive, debug tool interface, and I²C bidirectional data - reduces external component count. |

Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Power Modes | HALT, STOP, and SNOOZE modes enable sub-μA sleep states while retaining RAM and RTC; critical for energy harvesting systems. |
| Background Data Flash Operation | Not applicable - R5F101MGAFB#V0 lacks data flash; design must route non-volatile storage externally or use code flash with wear leveling. |
| On-Chip Oscillators | High-accuracy ±1.0% 32 MHz main oscillator + 32.768 kHz sub-oscillator; eliminates external crystal cost and layout area. |
| Peripheral Flexibility | Pin multiplexing allows UART, CSI, and I²C to share pins; reduces PCB layer count and routing complexity in space-constrained designs. |
| Industrial Temp Grade | G-grade qualification (−40°C to +105°C) ensures reliable operation in motor control enclosures and outdoor utility meters. |
| Debug & Programming | On-chip debug interface with SWJ support; enables in-system programming and real-time trace without additional debug headers. |

FAQ
What is the flash memory configuration of the R5F101MGAFB#V0?
The R5F101MGAFB#V0 contains 128 KB of code flash memory and no data flash memory - consistent with the R5F101x series designation. This distinguishes it from R5F100x variants, which include 4–8 KB of data flash. Firmware updates and program storage rely solely on the 128 KB code flash, which supports secure block erase prohibition and self-programming with boot swap functionality.
Does the R5F101MGAFB#V0 support background data flash operations?
No, the R5F101MGAFB#V0 does not include data flash memory and therefore does not support background operation (BGO) for data flash rewriting. BGO is only available on R5F100x series devices with integrated data flash. For R5F101MGAFB#V0, non-volatile data storage must be implemented externally or via code flash with careful wear-leveling management.
What is the operating temperature range for the R5F101MGAFB#V0?
The R5F101MGAFB#V0 is rated for −40°C to +105°C ambient temperature (G-grade), making it suitable for industrial motor drives, automotive under-hood modules, and outdoor utility equipment. This extended range is confirmed in the RL78/G13 datasheet Rev.3.80 and applies specifically to part numbers ending in 'G', including R5F101MGAFB#V0.
Which package type and pin count does the R5F101MGAFB#V0 use?
The R5F101MGAFB#V0 uses a 52-pin LFQFP package with 0.5 mm pitch (7 mm × 7 mm body), identified by the 'FB' suffix and '#V0' tray packaging code. This matches the RL78/G13 ordering convention where 'FB' denotes LFQFP-0.5 mm and 'MG' indicates 128 KB flash / G-grade temperature.
How does the R5F101MGAFB#V0 differ from the R5F100MGAFB#V0?
The R5F101MGAFB#V0 and R5F100MGAFB#V0 share identical code flash (128 KB), RAM (12 KB), package (52-pin LFQFP), and temperature grade (−40°C to +105°C), but differ in data flash: R5F101MGAFB#V0 has none, whereas R5F100MGAFB#V0 includes 8 KB data flash. This affects firmware update strategies and runtime parameter storage capability.
