It integrates an 8/10-bit 13-channel ADC, dual 8-bit DACs, two comparators, one PGA, nine 16-bit timers (including RTC and PWMOPA), UART/LIN, I²C, CSI, IrDA, DTC, ELC, and ultra-low-power modes (0.57 μA in RTC+LVD STOP mode). It targets battery-powered industrial sensors and smart metering interfaces.

For engineers reviewing the R5F11BBCAFP#30 datasheet, R5F11BBCAFP#30 pinout, R5F11BBCAFP#30 application, or R5F11BBCAFP#30 equivalent, this page delivers verified electrical specs, validated LQFP-32 pin mapping, confirmed peripheral allocation per Renesas R01DS0246EJ0130 Rev.1.30, and real-world substitution guidance for embedded control designs requiring low-voltage operation, analog integration, and LIN bus support.

Technical Context

The R5F11BBCAFP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.03125 μs @ 32 MHz high-speed on-chip oscillator or 30.5 μs @ 32.768 kHz subsystem clock). Its memory subsystem includes 32 KB code flash (1 KB block erase), 4 KB data flash with background operation (BGO) and 1M rewrite cycles, and 5.5 KB SRAM - with 4.5 KB usable during self-programming.

Peripherals are orchestrated via Event Link Controller (ELC) supporting 22 event sources linked to target functions, and Data Transfer Controller (DTC) with 32 activation sources enabling chain transfers. Power management includes HALT, STOP, and SNOOZE modes, on-chip POR (1.51 V ±0.04 V), and 14-level LVD with interrupt/reset selection - all qualified for −40 to +85°C operation (Consumer grade A).

FAQ

What is the maximum CPU clock frequency supported by the R5F11BBCAFP#30?

The R5F11BBCAFP#30 supports a maximum CPU operation frequency of 32 MHz, achievable using the high-speed on-chip oscillator (±1.0% accuracy over VDD = 1.8–5.5 V and TA = −20 to +85°C). External crystal (X1/X2) operation is limited to 20 MHz in HS mode at VDD ≥ 2.7 V, making the on-chip oscillator the optimal choice for full-speed deterministic timing in the R5F11BBCAFP#30.

Does the R5F11BBCAFP#30 support LIN bus communication?

Yes, the R5F11BBCAFP#30 supports LIN bus communication through its UART0 channel, which is explicitly documented in the R01DS0246EJ0130 datasheet as LIN-capable. This includes hardware-level support for LIN 2.2/SAE J2602 frame formatting, break detection, and sync field handling - enabling direct integration into automotive body electronics networks without external transceivers.

How many analog-to-digital converter channels does the R5F11BBCAFP#30 provide?

The R5F11BBCAFP#30 provides 13 analog input channels for its 8/10-bit successive-approximation ADC, as confirmed in Table 1-1 (Outline of Functions) of the R01DS0246EJ0130 datasheet for 32-pin devices. These include ANI0–ANI7, ANI16–ANI20, and ANI23–ANI24 - covering both primary and extended analog input groups with internal reference and temperature sensor support.

What is the data flash endurance specification for the R5F11BBCAFP#30?

The R5F11BBCAFP#30 specifies a data flash endurance of 1,000,000 write/erase cycles (typical), with operation supported across the full VDD range of 1.8–5.5 V. This endurance rating applies to the dedicated 4 KB data flash memory region - separate from code flash - and enables robust nonvolatile storage of calibration data, device configuration, or usage logs in long-life embedded applications.

Is the R5F11BBCAFP#30 pin-compatible with other RL78/G1F variants in the same package?

Yes, the R5F11BBCAFP#30 is pin-compatible with other RL78/G1F 32-pin LQFP devices including R5F11BBEAFP#30, R5F11BBCGFP, and R5F11BBEGFP - sharing identical pin count, mechanical footprint (PLQP0032GB-A), and functional pin assignment per the datasheet's Pin Configuration section. This allows seamless migration between 32 KB and 64 KB Flash variants without PCB redesign.
