Product details
Overview
R5F101GHAFB#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 memory, 12 KB RAM, and no data flash. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode) for battery-powered sensor nodes and motor control interfaces.
For engineers reviewing the R5F101GHAFB#X0 datasheet, R5F101GHAFB#X0 pinout, R5F101GHAFB#X0 application, or R5F101GHAFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of on-chip data flash, -40°C to +105°C industrial temperature rating (G-grade), and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, and CSI serial interfaces.
Technical Context
The R5F101GHAFB#X0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map includes 1 MB address space, on-chip debug support, and self-programming capability for code flash using boot swap and flash shield window functions.
Power management integrates an on-chip POR circuit, 14-level voltage detector (LVD) with interrupt/reset options, HALT/STOP/SNOOZE low-power modes, and real-time clock with calendar, alarm, and clock correction. Peripheral subsystems include DMA (4 channels), 16×16-bit multiplier/divider/MAC, and hardware BCD correction circuit.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GHAFB#V0 | Identical silicon, tray packaging instead of embossed tape | No functional difference; suited for manual prototyping or low-volume assembly | Select #V0 for engineering samples or small-batch builds where tape-and-reel feeders are unavailable |
| R5F100GHAFB#X0 | Same package and pinout, but includes 8 KB data flash and lacks G-grade (-40°C to +105°C) qualification (rated A/D-grade only) | Requires external nonvolatile storage for logging; unsuitable for high-temp industrial enclosures | Choose only if data flash persistence is mandatory and ambient temperature stays ≤ +85°C |
Compared with R5F101GHAFB#X0, the #V0 variant offers identical functionality in tray packaging for evaluation, while R5F100GHAFB#X0 trades industrial temperature range and data flash omission for persistent data storage - making it viable only in thermally controlled environments where logging is critical.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101GHAFB#X0?
The R5F101GHAFB#X0 achieves a maximum operating frequency of 32 MHz, delivering 41 DMIPS (Dhrystone MIPS) performance. This enables deterministic real-time execution for motor control loops, sensor fusion, and protocol stack processing. Its RL78 CPU core supports variable instruction timing - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed 32.768 kHz mode - allowing dynamic trade-offs between throughput and power consumption in the R5F101GHAFB#X0.
Does the R5F101GHAFB#X0 include on-chip data flash memory?
No, the R5F101GHAFB#X0 does not include on-chip data flash memory. As indicated by the "101" in its part number (per Renesas RL78/G13 naming convention), this variant provides 128 KB of code flash only. Applications requiring nonvolatile parameter storage must use the code flash with self-programming and boot swap functionality, or implement external EEPROM/FRAM. In contrast, R5F100xxx variants include 4–8 KB of dedicated data flash - a key differentiator confirmed in the R01DS0131EJ0380 datasheet for the R5F101GHAFB#X0.
What is the operating temperature range and industrial qualification status of the R5F101GHAFB#X0?
The R5F101GHAFB#X0 is rated for -40°C to +105°C operation and carries the "G" suffix per Renesas part numbering, confirming its qualification for industrial applications. This extended temperature range ensures reliable operation in demanding environments such as motor drive cabinets, outdoor HVAC units, and factory automation equipment. The device meets industrial-grade reliability requirements including enhanced ESD tolerance and long-term parametric stability - distinct from consumer-grade "A" (-40°C to +85°C) or standard industrial "D" variants. This specification is explicitly defined in the RL78/G13 datasheet section 1.1 and verified for the R5F101GHAFB#X0.
Which serial communication interfaces are integrated into the R5F101GHAFB#X0?
The R5F101GHAFB#X0 integrates three types of serial interfaces: up to 10 channels of I²C/Simplified I²C, up to 4 channels of UART/UART with LIN-bus support, and up to 8 channels of CSI (Renesas' SPI-compatible interface). These are multiplexed across GPIO pins - for example, P10/P11/P12 support SCK00/SI00/SO00 for CSI, while P30/P31 serve UART0. All interfaces operate across the full 1.6–5.5 V supply range and support clock stretching, multi-master arbitration, and automatic baud rate detection where applicable - enabling flexible connectivity to sensors, displays, and host processors in the R5F101GHAFB#X0.
How does the R5F101GHAFB#X0 support ultra-low-power system design?
The R5F101GHAFB#X0 supports ultra-low-power design through multiple hardware features: HALT mode (66 μA/MHz active current), STOP mode (0.57 μA with RTC + LVD enabled), and SNOOZE mode (selective peripheral wake-up without full CPU restart). Its on-chip 32.768 kHz oscillator drives the RTC independently, and the 14-level voltage detector allows precise brown-out monitoring. Combined with fast wake-up times (< 4 μs from STOP) and flexible clock gating, these capabilities allow the R5F101GHAFB#X0 to achieve multi-year battery life in sensor endpoints - validated in Renesas application notes ANR001 and ANR005 for RL78/G13.
