Product details
Overview
R5F100GLAFB#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, 12 KB RAM, and operation up to 32 MHz delivering 41 DMIPS - deployed in battery-powered sensor nodes, motor control modules, and smart home appliance controllers.
For engineers reviewing the R5F100GLAFB#X0 datasheet, R5F100GLAFB#X0 pinout, R5F100GLAFB#X0 application, or R5F100GLAFB#X0 equivalent, key selection criteria include 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 UART interfaces for embedded control systems.
Technical Context
The R5F100GLAFB#X0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution time from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Peripherals include 8× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar and correction, 1× watchdog timer, 2–4 channel DMA, and serial interfaces - CSI (SPI-compatible), UART/LIN (2–4 channels), and I²C (3–10 channels) - all accessible via configurable GPIO with N-ch open-drain, TTL input, and pull-up options.

The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GLAFB#X0 | No data flash (0 KB); identical core, peripherals, and package | Suitable only where non-volatile parameter storage is handled externally or not required | Select when firmware update persistence is managed via external EEPROM or cloud sync |

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GLAFB#X0?
The R5F100GLAFB#X0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This enables deterministic execution of real-time control loops, sensor fusion algorithms, and communication stack processing - verified under worst-case voltage (1.6 V) and temperature (+105°C) conditions per the R01DS0131EJ0380 datasheet.
Does the R5F100GLAFB#X0 include an integrated LIN physical layer?
The R5F100GLAFB#X0 does not integrate a LIN transceiver PHY, but its UART0 peripheral meets ISO 17987-4 timing requirements for LIN 2.2A/B communication. When paired with a standard LIN transceiver (e.g., TLE7259-3GE), it functions as a fully compliant LIN node - confirmed in Section 1.1 Features and Table 1-1 of the RL78/G13 datasheet.
What are the memory resources allocated to the R5F100GLAFB#X0?
The R5F100GLAFB#X0 integrates 128 KB of on-chip code flash memory, 8 KB of data flash memory (with background operation and 1,000,000 write cycles), and 12 KB of RAM. These values are explicitly listed in the "ROM, RAM capacities" table on page 2 of the R01DS0131EJ0380 datasheet for the 48-pin LFQFP variant with 'G' flash density and 'L' pin count.
Is the R5F100GLAFB#X0 qualified for industrial temperature operation?
Yes - the 'G' suffix in R5F100GLAFB#X0 denotes Industrial grade qualification with guaranteed operation from −40°C to +105°C. This is defined in Figure 1-1 ("Part Number, Memory Size, and Package") and confirmed in Table 1-1, where 'G' is explicitly assigned to industrial applications with extended ambient temperature range.
How many ADC input channels does the R5F100GLAFB#X0 support, and what is the resolution?
The R5F100GLAFB#X0 supports up to 26 analog input channels with 10-bit resolution. This is specified in the "A/D converter" subsection of Section 1.1 Features, which states "Analog input: 6 to 26 channels" and "8/10-bit resolution A/D converter", with the upper channel count confirmed for 48-pin and larger packages in the RL78/G13 family documentation.
