Renesas R5F11BBCGFP#30

Overview

R5F11BBCGFP#30 from Renesas Electronics is a 32-pin, 32 KB Flash, 4 KB Data Flash, 5.5 KB RAM RL78/G1F 16-bit microcontroller operating at up to 32 MHz with true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 8/10-bit ADC (13 channels), dual 8-bit DAC outputs, and integrated PGA, comparators, and LIN-capable UART - deployed in industrial sensor nodes and battery-powered control modules.

For engineers reviewing the R5F11BBCGFP#30 datasheet, R5F11BBCGFP#30 pinout, R5F11BBCGFP#30 application, or R5F11BBCGFP#30 equivalent, key selection criteria include its −40°C to +105°C industrial temperature grade, LFQFP-32 (7×7 mm, 0.8 mm pitch) package, 1.6–5.5 V single-supply operation, and support for SNOOZE mode background data flash rewriting with BGO.

Technical Context

The R5F11BBCGFP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz), low-speed 15 kHz internal RC oscillator, and dedicated subsystem clock domain for RTC and LVD.

Its peripheral set includes Timer Array Unit (TAU) with 4 channels, Timer RD (2-channel PWMOPA), Timer RG, Timer RX, and Event Link Controller (ELC) supporting 22 event sources linked to peripherals - enabling deterministic, low-CPU-overhead signal processing for real-time industrial I/O control.

FAQ

What is the maximum operating frequency and corresponding power consumption of the R5F11BBCGFP#30?

The R5F11BBCGFP#30 operates at up to 32 MHz using the high-speed on-chip oscillator. At this frequency and VDD = 3.3 V, typical active current is 66 μA/MHz - resulting in ~2.1 mA total. In STOP mode, it draws just 0.23 μA, and in HALT mode with RTC + LVD enabled, consumption drops to 0.57 μA. These values are measured per Renesas R01DS0246EJ0130 Rev.1.30 specifications.

Does the R5F11BBCGFP#30 support LIN bus communication, and which peripheral handles it?

Yes, the R5F11BBCGFP#30 supports LIN bus communication via its UART0 peripheral, which includes hardware LIN protocol features such as automatic sync-break detection, checksum calculation, and identifier filtering. This capability is confirmed in Section 1.1 Features and Table 1-1 of the R01DS0246EJ0130 datasheet, and applies specifically to the R5F11BBCGFP#30 variant.

How many analog-to-digital converter (ADC) channels does the R5F11BBCGFP#30 provide, and what resolutions are supported?

The R5F11BBCGFP#30 integrates an 8/10-bit successive-approximation ADC with 13 analog input channels (ANI0–ANI7, ANI16–ANI20). Resolution is software-selectable per conversion, and the module supports internal 1.45 V reference and temperature sensor input. This configuration is specified for 32-pin RL78/G1F devices in Section 1.6 Outline of Functions, Page 14 of R01DS0246EJ0130.

What packaging and pin pitch does the R5F11BBCGFP#30 use, and is it RoHS-compliant?

The R5F11BBCGFP#30 uses a 32-pin LFQFP package measuring 7 × 7 mm with 0.8 mm pin pitch, as defined in Figure 1-1 and Table 1-1 of R01DS0246EJ0130. It is lead-free and RoHS-compliant, with ordering code suffix "FP" denoting LFQFP and "#30" indicating tray packaging. The exposed die pad is not present in this variant - unlike HWQFN packages - and no thermal pad grounding is required.

Can the R5F11BBCGFP#30 perform background data flash rewriting while executing code from main flash memory?

Yes, the R5F11BBCGFP#30 supports Background Operation (BGO) for data flash rewriting. While code executes from main flash, the data flash (4 KB) can be rewritten - including erase and program operations - without halting CPU execution. This feature is documented in Section 1.1 Features and confirmed for all RL78/G1F variants, including R5F11BBCGFP#30, with 1,000,000 write cycles rated at VDD = 1.8–5.5 V.
