Renesas R5F11BLEAFB#30

Overview

R5F11BLEAFB#30 from Renesas Electronics is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), 64 KB flash, 5.5 KB RAM RL78/G1F microcontroller operating from 1.6 V to 5.5 V with true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 17-channel 8/10-bit ADC, dual 8-bit DAC, two comparators, PGA, nine 16-bit timers, RTC, and multiple serial interfaces (CSI, UART/LIN, I²C, IrDA) for embedded control in industrial sensor nodes and motor drives.

For engineers reviewing the R5F11BLEAFB#30 datasheet, R5F11BLEAFB#30 pinout, R5F11BLEAFB#30 application, or R5F11BLEAFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, 64 KB code flash with 4 KB data flash, 17 analog input channels, RTC calendar support, and industrial-grade −40°C to +105°C operation with LVD interrupt/reset across 14 voltage levels.

Technical Context

The R5F11BLEAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs at 32 MHz high-speed on-chip oscillator or 30.5 μs at 32.768 kHz subsystem clock). It supports multiply/divide/MAC instructions and 1 MB address space with four banks of 8-bit general-purpose registers.

Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR and LVD (14-level programmable), and independent EVDD0/EVSS0 supply domains for noise-sensitive analog/peripheral operation. The Event Link Controller (ELC) enables hardware-triggered peripheral chaining across 22 event sources without CPU intervention.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the R5F11BLEAFB#30?

The R5F11BLEAFB#30 achieves a maximum CPU operation frequency of 32 MHz using the high-speed on-chip oscillator. This requires VDD between 2.7 V and 5.5 V. At lower voltages (1.6–2.7 V), max frequency is reduced to 16 MHz (HS mode) or 8 MHz (LS mode) to maintain timing margins and reliability.

Does the R5F11BLEAFB#30 support LIN bus communication, and which UART channel provides it?

Yes, the R5F11BLEAFB#30 supports LIN bus communication on UART0 (RxD0/TxD0 pins), enabled via the LINSEL bit. UART0 operates at standard LIN baud rates (e.g., 19.2 kbps) and includes break detection, sync field handling, and checksum verification in hardware - eliminating software overhead for LIN protocol compliance.

How many analog input channels does the R5F11BLEAFB#30 support, and what reference options are available for the ADC?

The R5F11BLEAFB#30 supports 17 analog input channels (ANI0–ANI7 and ANI16–ANI24). The ADC accepts either VDD as reference or an internal 1.45 V reference (selectable via register). External reference is not supported; however, the integrated temperature sensor and internal reference enable calibration-free measurements in portable and industrial sensors.

What packaging and thermal specifications apply to the R5F11BLEAFB#30?

The R5F11BLEAFB#30 uses a 64-pin LFQFP package (10 × 10 mm, 0.5 mm pitch) with exposed die pad. Its operating ambient temperature range is −40°C to +85°C (A-grade), and it features dedicated EVDD0/EVSS0 pins to isolate analog power domains - critical for achieving specified ADC/DAC accuracy and LVD stability under thermal stress.

Can the R5F11BLEAFB#30 perform simultaneous ADC conversions and data flash writes without CPU intervention?

Yes, the R5F11BLEAFB#30 supports background operation (BGO) for data flash memory: while rewriting 4 KB data flash, the CPU can execute instructions from code flash. Combined with the Data Transfer Controller (DTC), ADC conversion results can be automatically stored to RAM or flash without CPU cycles - enabling deterministic real-time response in motor control and sensor acquisition.
