Product details
Overview
R5F101GHAFB#V0 from Renesas is a 48-pin LFQFP, 0.5-mm pitch, industrial-grade 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB RAM, and no data flash memory. 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-only STOP mode), targeting battery-powered sensor nodes and smart metering interfaces.
For engineers reviewing the R5F101GHAFB#V0 datasheet, R5F101GHAFB#V0 pinout, R5F101GHAFB#V0 application, or R5F101GHAFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, absence of on-chip data flash, -40°C to +105°C industrial temperature rating (G-grade), and integrated peripherals including 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces (CSI, UART/LIN, I²C).
Technical Context
The R5F101GHAFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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 spans 1 MB address space, with 128 KB code flash organized in 1 KB blocks and 8 KB SRAM.
Peripherals include eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock with alarm and correction, one watchdog timer, and a 10-bit A/D converter with up to 26 analog inputs and internal 1.45 V reference voltage - all operating across the full industrial temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GHAFB#X0 | Identical silicon; differs only in packaging - embossed tape instead of tray | No functional difference; selected for automated SMT line compatibility | Choose #X0 for high-volume pick-and-place assembly; #V0 preferred for prototyping and low-volume builds |
| R5F100GHAFB#V0 | Same package and pinout, but includes 8 KB data flash memory and supports background rewriting | Required where field-upgradable parameter storage (e.g., calibration tables, configuration profiles) is needed | Select R5F100GHAFB#V0 if nonvolatile parameter storage beyond code flash is mandatory; otherwise R5F101GHAFB#V0 reduces cost and simplifies firmware design |
Compared with R5F101GHAFB#V0, the R5F100GHAFB#V0 adds data flash for persistent configuration storage but increases cost and firmware complexity, while the R5F101GHAFB#X0 offers identical functionality in tape-and-reel format for production scalability - making the #V0 variant optimal for design flexibility and evaluation.

FAQ
What is the maximum operating frequency and performance of the R5F101GHAFB#V0?
The R5F101GHAFB#V0 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports variable instruction execution times - from 0.03125 μs in high-speed mode to 30.5 μs in ultra-low-speed 32.768 kHz mode - enabling dynamic power/performance scaling in the R5F101GHAFB#V0.
Does the R5F101GHAFB#V0 include on-chip data flash memory?
No, the R5F101GHAFB#V0 does not include data flash memory. As indicated by the "101" in its part number per Renesas' naming convention, it contains only 128 KB of code flash memory and 8 KB of SRAM. For data flash capability, consider the R5F100GHAFB#V0 variant, which integrates 8 KB of data flash with background rewrite support - a key distinction in the R5F101GHAFB#V0's feature set.
What is the operating temperature range supported by the R5F101GHAFB#V0?
The R5F101GHAFB#V0 is rated for industrial operation from -40°C to +105°C, denoted by the "G" suffix in its part number. This extended temperature range ensures reliable performance in demanding environments such as factory automation controllers, outdoor smart meters, and HVAC systems - distinguishing it from consumer-grade "A" (-40°C to +85°C) and standard industrial "D" variants of the RL78/G13 family.
Which package type and pin count does the R5F101GHAFB#V0 use?
The R5F101GHAFB#V0 uses a 48-pin LFQFP package with 0.5 mm pitch and 7 mm × 7 mm body size, identified by the "FB" suffix and "#V0" tray packaging code. This package provides full access to all 26 analog input channels, multiple serial interfaces, and timer resources - making it the highest-pin-count LFQFP option in the R5F101x series and ideal for complex sensor fusion or control applications requiring the R5F101GHAFB#V0.
How does the R5F101GHAFB#V0 support low-power system design?
The R5F101GHAFB#V0 supports low-power design through three key modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE (fast wake-up from peripheral events). Its single 1.6–5.5 V supply, integrated voltage detector, and configurable I/O retention further minimize system-level power - enabling multi-year battery operation in remote R5F101GHAFB#V0-based sensor nodes without compromising real-time responsiveness.
