Product details
Overview
R5F101GFAFB#10 from Renesas is a 48-pin LFQFP (7 × 7 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash memory, 8 KB data flash, and 12 KB RAM. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and achieves ultra-low power consumption of 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode - ideal for battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101GFAFB#10 datasheet, R5F101GFAFB#10 pinout, R5F101GFAFB#10 application, or R5F101GFAFB#10 equivalent, key selection criteria include its integrated real-time clock with calendar/alarm, 26-channel 10-bit ADC, dual UART/LIN support, and hardware DMA for deterministic sensor data acquisition in resource-constrained embedded systems.
Technical Context
The R5F101GFAFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB on-chip RAM - enabling robust firmware updates and nonvolatile parameter storage without halting execution.
Peripheral integration includes up to 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar-capable real-time clock (RTC), 1× watchdog timer, 2–4 channel DMA, and serial interfaces: 2–4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable for low-latency industrial control loops and multi-protocol communication stacks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GFAFB#30 | Identical silicon; differs only in packaging (embossed tape vs. tray) | No functional difference; selected for automated SMT line compatibility | Choose #30 for high-volume pick-and-place assembly; #10 for prototyping or low-volume hand-soldering |
| R5F100GFAFB#10 | Same package and pinout, but includes 8 KB data flash (R5F101GFAFB#10 has no data flash) | Required where persistent parameter storage (e.g., calibration data, device ID) must survive power loss without external EEPROM | Select R5F100GFAFB#10 if data flash usage is mandatory; otherwise R5F101GFAFB#10 reduces cost and simplifies firmware design |
Compared with R5F101GFAFB#30 and R5F100GFAFB#10, the R5F101GFAFB#10 provides optimal cost-performance balance for applications needing full 128 KB code flash and 12 KB RAM but no data flash - reducing BOM count and eliminating flash wear management overhead.

FAQ
What is the operating temperature range for R5F101GFAFB#10?
The R5F101GFAFB#10 is rated for industrial operation from −40°C to +105°C, as indicated by the 'G' suffix in its part number. This makes it suitable for deployment in harsh environments such as factory automation equipment, outdoor utility meters, and under-hood automotive subsystems where ambient thermal stress exceeds consumer-grade limits.
Does R5F101GFAFB#10 include data flash memory?
No, the R5F101GFAFB#10 does not include data flash memory. The '101' prefix in the part number explicitly denotes "data flash not provided", distinguishing it from '100' variants like R5F100GFAFB#10 which integrate 8 KB of data flash. Firmware must use code flash sectors or external nonvolatile memory for parameter storage.
What debug interface does R5F101GFAFB#10 support?
The R5F101GFAFB#10 supports Renesas' on-chip debug functionality via the single-wire SWD (Serial Wire Debug) interface using the dedicated DEBUG pin (P15). This enables full JTAG-equivalent debugging - including breakpoints, watchpoints, and memory inspection - without requiring additional pins or external debug probes beyond standard SWD headers.
Can R5F101GFAFB#10 operate from a 1.8 V supply?
Yes, the R5F101GFAFB#10 supports operation from 1.6 V to 5.5 V, so 1.8 V is fully within its specified VDD range. At this voltage, maximum operating frequency is reduced per datasheet derating curves - typically up to ~16 MHz for stable execution - enabling ultra-low-voltage operation in energy-harvesting or coin-cell powered designs.
How many UART channels are available on R5F101GFAFB#10?
The R5F101GFAFB#10 provides two UART channels (UART0 and UART1), both supporting LIN bus protocol. UART0 is pinned to P11 (RxD0) and P12 (TxD0); UART1 maps to P30 (RxD1) and P31 (TxD1). Each channel includes independent baud rate generators, FIFO buffers, and LIN-specific features like sync byte detection and checksum calculation.
