Product details
Overview
R5F101GGAFB#X0 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, 8 KB data flash, and 8 KB RAM. It operates from 1.6–5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode), targeting battery-powered sensor nodes and smart home control units.
For engineers reviewing the R5F101GGAFB#X0 datasheet, R5F101GGAFB#X0 pinout, R5F101GGAFB#X0 application, or R5F101GGAFB#X0 equivalent, key selection criteria include its integrated RTC with calendar/alarm, 10-bit 26-channel ADC with internal temperature sensor, dual UART/LIN support, and hardware DMA for deterministic peripheral-to-memory transfers in resource-constrained embedded systems.
Technical Context
The R5F101GGAFB#X0 implements the RL78 CPU core with a 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 architecture includes separate code flash (128 KB, 1 KB blocks), data flash (8 KB, 1M write cycles), and SRAM (8 KB), all accessible under single-supply operation.
Peripherals include eight 16-bit timers, one 12-bit interval timer, one real-time clock with calendar and correction, one watchdog timer, up to ten I²C/Simplified I²C channels, four UART/LIN interfaces, and two to eight CSI (SPI-compatible) channels - all configurable via register-based control without external glue logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GGAFB#X0 | Includes 8 KB data flash; same package, pinout, and peripherals but adds data flash for nonvolatile parameter storage | Preferred where field-updatable calibration tables or device configuration must persist across power cycles | Select when data flash endurance (1M cycles) and BGO capability are required for runtime reprogramming |
| R5F101GGAFA#V0 | Same core and memory, but in 48-pin LQFP (0.65-mm pitch) instead of LFQFP (0.5-mm pitch); identical functionality | Suitable for legacy PCBs designed for standard LQFP footprints or where reflow profile favors larger pitch | Choose for compatibility with existing LQFP assembly lines or when finer pitch handling is not available |
Compared with R5F100GGAFB#X0, the R5F101GGAFB#X0 omits data flash to reduce cost and die size while retaining full code flash and peripheral set; compared with R5F101GGAFA#V0, it uses a denser LFQFP package enabling smaller board area but requiring tighter placement tolerances.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101GGAFB#X0?
The R5F101GGAFB#X0 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This enables deterministic execution of real-time control algorithms, such as PID loops or sensor fusion, with sub-10 μs interrupt response latency in optimized configurations. The RL78 core's 3-stage pipeline ensures consistent throughput across varying clock speeds.
Does the R5F101GGAFB#X0 include an integrated real-time clock (RTC)?
Yes, the R5F101GGAFB#X0 integrates a full-featured RTC with calendar support (99-year range), alarm interrupt, and automatic clock correction. It operates independently in STOP mode with only RTC and LVD active, consuming just 0.57 μA - making it ideal for time-stamped data logging or wake-on-alarm applications without external timing components.
What are the memory resources available on the R5F101GGAFB#X0?
The R5F101GGAFB#X0 provides 128 KB of code flash memory (organized in 1 KB blocks with security lock), 8 KB of data flash memory (supporting background operation and 1 million write cycles), and 8 KB of on-chip RAM. The flash library reserves specific RAM regions (e.g., FEF00H for R5F101xE variants) for self-programming operations, documented in Renesas' Flash Self-Programming Library guide.
How does the R5F101GGAFB#X0 support low-power operation in battery-powered systems?
The R5F101GGAFB#X0 supports multiple low-power modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE. Its 1.6–5.5 V wide supply range, programmable LVD with 14 thresholds, and ability to wake from STOP via external interrupt or RTC alarm make it suitable for multi-year battery life in wireless sensors and portable medical devices.
Is the R5F101GGAFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F101GGAFB#X0 is pin-compatible with all 48-pin LFQFP RL78/G13 variants (e.g., R5F100GGAFB#X0, R5F101GGAFA#V0 differs only in pitch). Pin functions are consistent across the family, allowing hardware reuse when migrating between flash sizes or data flash inclusion - provided software accounts for memory map and peripheral enable differences.
