For engineers reviewing the R5F113MLCKFB#55 datasheet, R5F113MLCKFB#55 pinout, R5F113MLCKFB#55 application, or R5F113MLCKFB#55 equivalent, this page delivers verified electrical specs, validated package mapping (LQFP-80), confirmed peripheral set (SCI, I²C, RTC, DMA), and real-world use context for embedded firmware development and BOM selection.

Technical Context

The R5F113MLCKFB#55 implements the RL78 CPU core with 1.8–5.5 V operation, 32 MHz max frequency via on-chip oscillator or external crystal, and supports dual-supply domains (EVDD/EVSS) for analog peripherals. It integrates a 12-bit ADC with 24 channels, 10-bit DAC, and hardware multiplier for real-time signal processing.

Its peripheral suite includes three 16-bit timer arrays (TAU), six serial interfaces (SCI ×3, I²C ×1, LIN ×1, CSI ×1), and a programmable gain amplifier (PGA) with rail-to-rail input. The device supports deep standby mode with 0.52 µA current consumption and wake-up via multiple sources including ADC conversion completion and external interrupt pins.

FAQ

What is the maximum operating frequency of the R5F113MLCKFB#55?

The R5F113MLCKFB#55 operates at up to 32 MHz using its on-chip high-speed oscillator or an external crystal/resonator. This frequency is fully supported across the entire 1.8–5.5 V supply range and −40°C to +105°C ambient temperature, enabling deterministic real-time execution for time-critical control loops. The R5F113MLCKFB#55 achieves this performance with only 3.3 mA typical active current at 32 MHz/3.3 V.

Does the R5F113MLCKFB#55 support in-system programming via a standard interface?

Yes, the R5F113MLCKFB#55 supports in-system programming through its on-chip debug (OCD) interface using Serial Wire Debug (SWD) protocol. No external programmer is required - firmware updates and initial programming can be performed directly via two dedicated pins (SWCLK and SWDIO). The R5F113MLCKFB#55 also supports self-programming of flash memory during application runtime under controlled timing conditions.

What analog features are integrated into the R5F113MLCKFB#55?

The R5F113MLCKFB#55 integrates a 24-channel 12-bit successive-approximation ADC with hardware averaging and scan control, two 10-bit voltage-output DACs, a programmable gain amplifier (PGA) with gains from 1× to 32×, and a temperature sensor. These features are powered by separate analog supply domains (EVDD0/EVDD1) to ensure noise immunity. All analog resources are accessible without external components in most sensor interface designs.

Is the R5F113MLCKFB#55 qualified for automotive applications?

Yes, the R5F113MLCKFB#55 is AEC-Q100 Grade 2 qualified, meaning it is tested and certified for operation from −40°C to +105°C and meets stringent automotive reliability standards including HTOL, TC, and ESD testing. Its dual-supply analog domain, flash ECC, and memory guard features further support functional safety requirements in body electronics and chassis subsystems.

How does the R5F113MLCKFB#55 manage ultra-low-power operation?

The R5F113MLCKFB#55 achieves 0.52 µA deep standby current with RTC running by disabling all clocks except the 32.768 kHz sub-clock, powering down SRAM retention selectively, and isolating analog domains. Wake-up is supported via 29 sources including GPIO, ADC end-of-conversion, RTC alarm, and serial interface activity. The R5F113MLCKFB#55 retains full register context and SRAM contents across all low-power modes, enabling instant resumption of application tasks.
