Renesas R5F11BLEGFB#30

Overview

R5F11BLEGFB#30 from Renesas is a 64-pin LFQFP, 64 KB Flash, 5.5 KB RAM RL78/G1F microcontroller with 17-channel 8/10-bit ADC, dual 8-bit DAC, two comparators, and programmable gain amplifier - operating from 1.6 V to 5.5 V at −40°C to +105°C for industrial sensor control and low-power HMI applications.

For engineers reviewing the R5F11BLEGFB#30 datasheet, R5F11BLEGFB#30 pinout, R5F11BLEGFB#30 application, or R5F11BLEGFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, 64 KB code flash with self-programming, real-time clock with calendar, and support for LIN-bus UART, I²C, and CSI serial interfaces in industrial temperature grade.

Technical Context

The R5F11BLEGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-speed on-chip oscillator (±1.0% accuracy across 1–32 MHz), low-speed oscillator (15 kHz), and voltage detector with 14-level LVD interrupt/reset selection.

Its peripheral set includes Timer Array Unit (4 channels), Timer RD (2 PWM-capable channels), RTC with alarm/calendar, DTC with 33 sources, ELC supporting 22 event signals, and dual simplified I²C/SPI/UART interfaces - all optimized for deterministic real-time response in battery-powered industrial nodes.

FAQ

What is the maximum operating frequency and minimum instruction execution time of the R5F11BLEGFB#30?

The R5F11BLEGFB#30 supports maximum CPU operation at 32 MHz using the high-speed on-chip oscillator, achieving a minimum instruction execution time of 0.03125 μs. At 32.768 kHz subsystem clock, the minimum instruction time is 30.5 μs - enabling ultra-low-power real-time operation while maintaining deterministic timing for RTC and sensor sampling tasks.

Does the R5F11BLEGFB#30 support LIN bus communication, and which UART channel implements it?

Yes, the R5F11BLEGFB#30 supports LIN bus communication on UART0 (RxD0/TxD0 pins), with hardware LINSEL functionality enabling automatic sync-break detection and LIN protocol compliance. This capability is confirmed in the RL78/G1F datasheet Section 1.2 and functional outline tables for 64-pin devices.

What are the analog capabilities of the R5F11BLEGFB#30, and how many channels does the ADC support?

The R5F11BLEGFB#30 integrates an 8/10-bit resolution ADC with 17 analog input channels (ANI0–ANI7, ANI16–ANI24), dual 8-bit DACs (ANO0/ANO1), two comparators (IVCMP0/1), and a programmable gain amplifier (PGAI/PGAGND). These resources are fully accessible in the 64-pin configuration per datasheet Table 1-1 and Section 1.6.

How does the R5F11BLEGFB#30 manage power supply domains for analog and digital sections?

The R5F11BLEGFB#30 uses separate power domains: VDD/EVDD0 and VSS/EVSS0. EVDD0 powers analog peripherals (ADC, DAC, PGA, comparators) and EVSS0 serves as their dedicated ground return - reducing digital switching noise coupling into sensitive analog measurements. This separation is mandatory per datasheet Caution 1.3.5 and electrical specification guidelines.

What debug and programming features are supported by the R5F11BLEGFB#30, and are they production-safe?

The R5F11BLEGFB#30 includes on-chip debug functionality via TOOL0/TOOLRxD/TOOLTxD pins and supports self-programming with boot swap and flash shield window. However, Renesas explicitly cautions against using the on-chip debug function in mass production due to potential flash endurance limits - production firmware should be programmed via standard SWD or FINE interface without debug activation.
