Product details
Overview
R5F11BGCAFB#30 from Renesas Electronics is a 48-pin LFQFP, 32 KB 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), 17-channel 8/10-bit ADC, dual 8-bit DAC, and integrated PGA-designed for battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F11BGCAFB#30 datasheet, R5F11BGCAFB#30 pinout, R5F11BGCAFB#30 application, or R5F11BGCAFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, 32 KB code flash with self-programming and boot swap, 4 KB data flash with background operation (1M rewrite cycles), and support for LIN-bus UART, dual I²C, and CSI serial interfaces in industrial temperature range (−40°C to +105°C).
Technical Context
The R5F11BGCAFB#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, 1–32 MHz) and low-speed oscillator (15 kHz), enabling precise clock domain management across ultra-low-power STOP/HALT/SNOOZE modes.
Its peripheral set includes a 9-channel 16-bit Timer Array Unit (TAU) with PWMOPA support, real-time clock with calendar and alarm, watchdog timer, 2-channel comparator with internal/external reference selection, and Event Link Controller (ELC) linking 22 event sources to peripherals-enabling deterministic, low-CPU-overhead signal processing for closed-loop control and sensor fusion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F11BGEAFB#30 | 64 KB flash (vs. 32 KB), same 48-pin LFQFP package, identical peripherals and clock system | Required when firmware exceeds 32 KB or future-proofing for feature expansion is needed | Select R5F11BGEAFB#30 if application requires >32 KB code space while retaining identical pinout and peripheral compatibility |
| RL78/G13 R5F10ABEAFP#30 | 32 KB flash, 4 KB RAM, 48-pin LQFP-0.8 mm (not 0.5 mm), no PGA, fewer ADC channels (12 vs. 17), no LIN support | Suitable for cost-sensitive consumer appliances where industrial temp range and advanced analog features are unnecessary | Choose R5F10ABEAFP#30 only for non-industrial applications with relaxed analog requirements and existing 0.8 mm pitch PCB layouts |
Compared with R5F11BGEAFB#30, the R5F11BGCAFB#30 trades flash capacity for lower cost and smaller memory footprint-ideal for fixed-function firmware; versus R5F10ABEAFP#30, it delivers superior analog integration, LIN capability, and industrial-grade reliability at the expense of package pitch compatibility.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F11BGCAFB#30?
The R5F11BGCAFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator. At this frequency, active current consumption is specified at 66 μA per MHz (i.e., ~2.1 mA typical at 32 MHz, VDD = 3.3 V, TA = 25°C). In STOP mode with RTC + LVD active, it draws just 0.57 μA-enabling decade-long battery life in always-on sensing applications.
Does the R5F11BGCAFB#30 support LIN bus communication, and which UART channel implements it?
Yes, the R5F11BGCAFB#30 supports LIN bus communication via UART0. The RxD0 pin includes a dedicated LINSEL function that configures the UART for LIN physical layer compliance (ISO 17987-4), enabling direct connection to LIN transceivers without external level-shifting or protocol translation. This is confirmed in Section 1.1 Features and Table 1-1 of the R01DS0246EJ0130 datasheet.
How many analog input channels does the R5F11BGCAFB#30 support, and what is their voltage reference configuration?
The R5F11BGCAFB#30 supports 17 analog input channels (ANI0–ANI7 and ANI16–ANI24). These channels accept inputs referenced to either the external AVREFP/AVREFM pins or the internal 1.45 V reference voltage. The ADC operates across the full VDD range (1.6–5.5 V) and includes an integrated temperature sensor for system-level thermal monitoring.
What packaging and lead pitch does the R5F11BGCAFB#30 use, and what is the required REGC decoupling?
The R5F11BGCAFB#30 uses a 48-pin LFQFP package with 0.50 mm lead pitch (7 × 7 mm body). Per Section 1.3.4 and Caution notes in the R01DS0246EJ0130 datasheet, a 0.47 μF to 1.0 μF ceramic capacitor must be placed between the REGC pin and VSS to stabilize the internal voltage regulator-failure to do so may cause erratic reset behavior or brownout conditions.
Can the R5F11BGCAFB#30 perform simultaneous flash read and write operations, and how is data flash endurance rated?
Yes-the R5F11BGCAFB#30 supports Background Operation (BGO) for data flash, allowing program execution from code flash while rewriting data flash. Its 4 KB data flash is rated for 1,000,000 rewrite cycles (typical) across the full VDD range (1.8–5.5 V), enabling reliable storage of calibration coefficients, usage logs, and field-upgradable parameters without wear leveling overhead.
