Overview
R5F11BGEAFB#30 from Renesas is a 48-pin LFQFP 8-bit RL78/G1F microcontroller with 64 KB flash, 5.5 KB RAM, and 4 KB data flash. It operates from 1.6 V to 5.5 V, achieves 32 MHz CPU speed, and delivers ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), targeting battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F11BGEAFB#30 datasheet, R5F11BGEAFB#30 pinout, R5F11BGEAFB#30 application, or R5F11BGEAFB#30 equivalent, key selection criteria include its 17-channel 8/10-bit ADC, dual 8-bit DAC outputs, integrated PGA and two comparators, LIN-capable UART, and hardware event-link controller for deterministic peripheral triggering in real-time control loops.
Technical Context
The R5F11BGEAFB#30 implements the RL78 CISC core with 3-stage pipeline, supporting multiply/divide/MAC instructions and 1 MB address space. Its clock system integrates high-accuracy ±1.0% on-chip oscillators (1–32 MHz), 32.768 kHz crystal subsystem, and low-speed 15 kHz RC oscillator - all selectable via software without external components.
Peripheral integration includes Timer Array Unit (TAU) with 4 channels, Timer RD (2 PWMOPA-capable), RTC with calendar/alarm, DTC with 32 sources, ELC supporting 22 event inputs linked to peripherals, and simplified SPI/I²C/UART interfaces - all configurable via I/O redirection registers (PIOR0–PIOR3) for flexible pin mapping.

FAQ
What is the maximum operating frequency and voltage range supported by the R5F11BGEAFB#30?
The R5F11BGEAFB#30 supports a maximum CPU operation frequency of 32 MHz using its high-accuracy on-chip oscillator. It operates across a wide voltage range of 1.6 V to 5.5 V, enabling direct compatibility with single-cell Li-ion, 3.3 V, and 5 V systems. At 1.6 V minimum, the device maintains full functionality including ADC, DAC, and real-time clock operation - critical for deep-discharge battery applications.
Does the R5F11BGEAFB#30 support LIN bus communication, and how is it implemented?
Yes, the R5F11BGEAFB#30 supports LIN bus communication through its UART0 peripheral, which includes dedicated LINSEL pin functionality for automatic sync-break detection and checksum handling. The UART operates at standard LIN baud rates (e.g., 19.2 kbps) and integrates with the Event Link Controller to trigger ADC sampling or GPIO toggles upon frame reception - enabling deterministic slave-node response without CPU polling overhead.
How many analog-to-digital converter channels does the R5F11BGEAFB#30 provide, and what are their resolution and reference options?
The R5F11BGEAFB#30 provides 17 analog input channels with selectable 8-bit or 10-bit resolution. Conversion uses either the internal 1.45 V reference or the externally supplied AVREFP/AVREFM pins. The ADC supports simultaneous sampling of up to 4 channels via hardware triggers, and includes an integrated temperature sensor for on-die thermal monitoring - eliminating need for external sensing components in thermal-aware designs.
What packaging and lead-free compliance status does the R5F11BGEAFB#30 have?
The R5F11BGEAFB#30 is packaged in a 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) with lead-free, RoHS-compliant terminations. The package features an exposed thermal pad that must be soldered to a VSS-connected copper area for optimal thermal performance and EMI reduction. This footprint is shared with other RL78/G1F 48-pin variants, enabling design reuse across flash-size options.
Can the R5F11BGEAFB#30 perform background data flash writes while executing application code from main flash memory?
Yes, the R5F11BGEAFB#30 supports Background Operation (BGO) for data flash memory, allowing the CPU to execute instructions from code flash while concurrently rewriting the 4 KB data flash sector. This enables seamless firmware parameter updates, data logging, or calibration storage without interrupting real-time tasks - critical for applications requiring uninterrupted sensor acquisition or motor control loops.
