Product details
Overview
R5F101GLAFB#X0 from Renesas is a 48-pin LFQFP (7 × 7 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with no data flash, 128 KB code flash, 12 KB RAM, and operation up to 32 MHz delivering 41 DMIPS - deployed in battery-powered sensor nodes, HVAC controllers, and smart metering interfaces.
For engineers reviewing the R5F101GLAFB#X0 datasheet, R5F101GLAFB#X0 pinout, R5F101GLAFB#X0 application, or R5F101GLAFB#X0 equivalent, key selection criteria include its ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock with calendar/alarm, and LIN-capable UARTs for automotive body electronics and industrial I/O modules.
Technical Context
The R5F101GLAFB#X0 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 subsystem clock). It integrates a 12-bit interval timer, 16-bit timers (12 channels), and background operation for data flash writes - though this variant omits data flash memory entirely.
Its power management includes on-chip POR and LVD with 14 selectable voltage detection levels, DMA controller (4 channels), and hardware multiplier/divider/MAC. The device operates across –40°C to +105°C (G-grade), targeting industrial applications requiring robust timing, analog sensing, and low-voltage resilience.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GLAFP#V0 | Same core, memory, and peripherals; differs only in packaging (48-pin LQFP, 0.65-mm pitch vs. LFQFP 0.5-mm pitch) | Requires PCB layout change due to larger pad pitch and footprint; suitable for manual assembly or legacy board designs | Select when existing LQFP tooling or reflow profiles favor 0.65-mm pitch; identical firmware compatibility |
| R5F100GLAFB#X0 | Includes 8 KB data flash (vs. none); otherwise identical package, flash/RAM size, and peripheral set | Required where field firmware updates or parameter storage demand nonvolatile data retention independent of code flash | Choose when EEPROM-like data logging or bootloader swap functionality is needed - adds 8 KB data flash with 1M rewrite cycles |
Compared with R5F101GLAFP#V0 and R5F100GLAFB#X0, the R5F101GLAFB#X0 offers the smallest footprint among 48-pin RL78/G13 variants while omitting data flash - optimizing cost and board space for fixed-function industrial controllers where runtime data persistence is unnecessary.

FAQ
What is the operating temperature range for the R5F101GLAFB#X0?
The R5F101GLAFB#X0 is rated for industrial operation from –40°C to +105°C (G-grade), validated per Renesas specification R01DS0131EJ0380. This range supports deployment in under-hood automotive modules, factory-floor PLCs, and outdoor utility meters where ambient extremes are common. The device maintains full parameter compliance across this span without derating.
Does the R5F101GLAFB#X0 include data flash memory?
No, the R5F101GLAFB#X0 does not include data flash memory. As confirmed in the RL78/G13 datasheet section 1.2 (Part Number Decoding), the "101" prefix explicitly denotes "data flash not provided". This variant contains 128 KB code flash and 12 KB RAM only - intended for applications where configuration storage is handled externally or via code flash emulation.
What package type and pin pitch does the R5F101GLAFB#X0 use?
The R5F101GLAFB#X0 uses a 48-pin LFQFP package with 7 mm × 7 mm body size and 0.50-mm lead pitch, as defined in Renesas ordering code suffix "FB" and packaging specification #X0 (embossed tape). This fine-pitch QFP enables higher I/O density than standard LQFP variants while remaining compatible with mainstream SMT assembly lines.
Can the R5F101GLAFB#X0 operate from a 1.8 V supply?
Yes, the R5F101GLAFB#X0 supports single-supply operation from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, it achieves up to 16 MHz operation (per datasheet Section 1.1), maintaining full peripheral functionality except for high-speed oscillator modes above 24 MHz. This enables direct interface with 1.8 V logic families and low-voltage battery systems.
How many ADC input channels does the R5F101GLAFB#X0 support?
The R5F101GLAFB#X0 supports up to 26 analog input channels for its 10-bit successive-approximation ADC, as specified in the RL78/G13 datasheet Section 1.1. These channels are distributed across multiple port groups (P0–P5) and include dedicated analog pins like P20/ANI0 and P21/ANI1, plus shared digital I/O pins configurable as analog inputs.
