Product details
Overview
R5F11BGEGFB#30 from Renesas is a 48-pin LFQFP, industrial-grade (−40 to +105°C) 16-bit RL78/G1F microcontroller with 64 KB flash, 4 KB data flash, 5.5 KB RAM, and true low-power operation down to 66 μA/MHz and 0.57 μA in RTC+LVD mode. It integrates 17-channel 8/10-bit ADC, dual 8-bit DAC, two comparators, PGA, nine 16-bit timers (including PWMOPA), RTC with calendar, IrDA, LIN-capable UART, and up to six I²C/CSI channels - deployed in battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F11BGEGFB#30 datasheet, R5F11BGEGFB#30 pinout, R5F11BGEGFB#30 application, or R5F11BGEGFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, 64 KB flash with self-programming and boot swap, 1.6–5.5 V wide-voltage operation, integrated analog peripherals (ADC/DAC/PGA/comparator), and ELC-triggered peripheral coordination for deterministic real-time response.
Technical Context
The R5F11BGEGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing from 0.03125 μs (32 MHz on-chip oscillator) to 30.5 μs (32.768 kHz subsystem clock). It supports multiply/divide/MAC instructions and 1 MB address space across four register banks.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR/LVD (14-level selectable), and regulator capacitor (REGC) support for stable internal voltage generation. The Event Link Controller (ELC) enables direct hardware linking of 22 event sources to peripheral functions without CPU intervention.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R5F11BGEGFB#30?
The R5F11BGEGFB#30 achieves a maximum CPU operation frequency of 32 MHz using the high-speed on-chip oscillator. This requires VDD = 2.7–5.5 V. At lower voltages (2.4–5.5 V), max frequency is 16 MHz; at 1.8–2.7 V, it drops to 8 MHz; and at 1.6–1.8 V, it is limited to 4 MHz. These ranges ensure robust operation across diverse industrial power environments while maintaining the 66 μA/MHz efficiency target.
Does the R5F11BGEGFB#30 support hardware-based peripheral synchronization without CPU involvement?
Yes, the R5F11BGEGFB#30 includes an Event Link Controller (ELC) that enables direct hardware linking of 22 event sources (e.g., ADC end-of-conversion, timer overflow, external interrupt) to 10 peripheral trigger destinations (e.g., DTC start, DAC update, timer gate). This eliminates software latency and CPU polling, allowing deterministic sub-microsecond response - essential for closed-loop motor control and synchronized sensor acquisition.
How many analog-to-digital converter channels does the R5F11BGEGFB#30 provide, and what reference options are available?
The R5F11BGEGFB#30 provides 17 analog input channels (ANI0–ANI7 and ANI16–ANI24) with 8/10-bit resolution. Reference options include VDD (1.6–5.5 V), internal 1.45 V bandgap, and external AVREFP/AVREFM pins. The internal temperature sensor and selectable reference voltage allow accurate ambient and junction temperature measurement without external components.
Can the R5F11BGEGFB#30 perform flash memory updates while executing application code?
Yes, the R5F11BGEGFB#30 supports Background Operation (BGO) for its 4 KB data flash memory. Application code runs from main flash while data flash is rewritten - enabling seamless firmware parameter updates, calibration storage, or secure key management without halting real-time tasks. Code flash self-programming is also supported, including boot-swap functionality for fail-safe OTA upgrades.
What debug interface does the R5F11BGEGFB#30 use, and is external hardware required?
The R5F11BGEGFB#30 integrates a full SWD-compatible on-chip debug interface accessible via dedicated TOOL0, TOOLRxD, and TOOLTxD pins. No external debug probe is required for basic programming and debugging - a standard SWD/JTAG adapter suffices. Trace functionality is supported, and the interface remains active in HALT mode, enabling real-time variable inspection and breakpoint execution without disrupting system timing.
