Renesas R5F11BBEAFP#30

Overview

R5F11BBEAFP#30 from Renesas is a 32-pin LQFP (7 × 7 mm, 0.8 mm pitch), 64 KB Flash, 5.5 KB RAM RL78/G1F microcontroller with 16-bit TAU timer array, 8/10-bit 13-channel ADC, and dual UART/LIN interfaces - designed for ultra-low-power industrial sensor nodes and battery-powered control systems operating from 1.6 V to 5.5 V.

For engineers reviewing the R5F11BBEAFP#30 datasheet, R5F11BBEAFP#30 pinout, R5F11BBEAFP#30 application, or R5F11BBEAFP#30 equivalent, key selection criteria include its 64 KB code flash with self-programming and boot swap, 4 KB data flash with background operation (BGO), ±1.0% high-speed on-chip oscillator accuracy across −40°C to +85°C, and integrated RTC with calendar and alarm functions.

Technical Context

The R5F11BBEAFP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs at 32 MHz up to 30.5 μs at 32.768 kHz). It integrates an event link controller (ELC) supporting 22 event sources linked to peripherals, and a data transfer controller (DTC) with 32 activation sources enabling chain transfers without CPU intervention.

Its analog subsystem includes two comparators (one with pin-selectable input), a programmable gain amplifier (PGA), and a 12-bit interval timer - all operating under the same ultra-low-power HALT/STOP/SNOOZE modes that achieve 66 μA/MHz active current and 0.57 μA in RTC+LVD mode.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the R5F11BBEAFP#30?

The R5F11BBEAFP#30 supports up to 32 MHz CPU operation using the high-speed on-chip oscillator, with guaranteed operation from 1.6 V to 5.5 V. At 32 MHz, minimum VDD is 2.7 V per electrical specifications; below 2.7 V, max frequency scales down to 16 MHz (VDD ≥ 2.4 V), 8 MHz (VDD ≥ 1.8 V), or 4 MHz (VDD ≥ 1.6 V). The R5F11BBEAFP#30 datasheet specifies these voltage-frequency boundaries explicitly in Section 2.2.

Does the R5F11BBEAFP#30 support hardware-based background data flash rewriting while executing code from main flash?

Yes, the R5F11BBEAFP#30 supports Background Operation (BGO) for data flash memory. This allows the CPU to execute instructions from code flash while simultaneously rewriting the 4 KB data flash - essential for real-time logging, parameter storage, or firmware configuration updates without service interruption. The R5F11BBEAFP#30 implements this via dedicated hardware control logic, not software polling.

How many independent serial communication interfaces does the R5F11BBEAFP#30 provide, and which protocols are supported?

The R5F11BBEAFP#30 provides three UART channels (one with LIN-bus support), three simplified I²C interfaces, and three CSI (SPI-compatible) channels - totaling nine independent serial interfaces. All are hardware-peripheral based with dedicated registers and interrupt vectors. The R5F11BBEAFP#30 does not share physical pins across interface types by default; each channel maps to distinct pins unless redirected via PIOR registers.

What analog features are integrated into the R5F11BBEAFP#30, and how are they utilized in sensor applications?

The R5F11BBEAFP#30 integrates a 13-channel 8/10-bit ADC with internal 1.45 V reference and temperature sensor, two comparators (one with pin-selectable input), one programmable gain amplifier (PGA), and dual 8-bit D/A converters. In sensor applications, the R5F11BBEAFP#30 uses the PGA to amplify weak signals from bridge sensors, the ADC to digitize conditioned outputs, and comparators for threshold-triggered interrupts - all without external signal-chain components.

Is the R5F11BBEAFP#30 pin-compatible with other RL78/G1F variants in the same 32-pin LQFP package?

Yes, all RL78/G1F 32-pin LQFP variants - including R5F11BBCAFP#30 (32 KB flash), R5F11BBEAFP#30 (64 KB flash), and their 'G' industrial-grade counterparts - share identical pinouts and electrical characteristics. This allows direct PCB reuse across memory variants and temperature grades, simplifying design scaling and qualification. The R5F11BBEAFP#30 maintains full functional and mechanical compatibility within this 32-pin LQFP family.
