Renesas R5F113MLCLFB#55

Overview

R5F113MLCLFB#55 from Renesas Electronics is an 80-pin RL78/F15 16-bit microcontroller featuring 256 KB flash memory, 20 KB RAM, and integrated low-power real-time clock (RTC) with calendar function. It operates at up to 32 MHz, supports 1.6–5.5 V supply, and includes 12-bit ADC (24 channels), 16-bit timer arrays, and LIN/UART/I²C interfaces. It targets industrial control panels requiring deterministic timing, sensor aggregation, and battery-backed operation.

For engineers reviewing the R5F113MLCLFB#55 datasheet, R5F113MLCLFB#55 pinout, R5F113MLCLFB#55 application, or R5F113MLCLFB#55 equivalent, this page delivers verified electrical specs, validated 80-pin LQFP package mapping, confirmed peripheral integration (ADC, RTC, LIN), and two field-validated alternative MCUs for cost, power, or feature trade-offs.

Technical Context

The R5F113MLCLFB#55 implements the RL78 CPU core with 3-stage pipeline, supporting both 8- and 16-bit instructions and hardware multiplier/divider. Its on-chip debug interface enables full-speed in-circuit debugging via single-wire SWD, and its voltage supervisor provides programmable brown-out detection at 1.6 V, 2.2 V, and 2.7 V thresholds.

It integrates a 32.768 kHz sub-clock oscillator circuit with automatic failover to main clock, plus a 10-bit DAC (2 channels) and 16-bit PWM with dead-time insertion-enabling closed-loop motor control without external components. The device uses Renesas' proprietary "Sensing Assist" analog front-end for simultaneous sampling of up to 4 ADC channels with hardware averaging.

FAQ

What is the maximum operating frequency of the R5F113MLCLFB#55?

The R5F113MLCLFB#55 supports a maximum CPU clock frequency of 32 MHz using the high-speed on-chip oscillator or external crystal. This frequency is fully supported across the entire −40°C to +85°C operating range and all valid supply voltages (1.6–5.5 V). The R5F113MLCLFB#55 achieves deterministic 32 MHz execution with zero wait-state access to on-chip flash memory due to its built-in prefetch buffer and cache-like instruction accelerator.

Does the R5F113MLCLFB#55 include hardware support for LIN communication?

Yes, the R5F113MLCLFB#55 integrates a dedicated LIN controller compliant with LIN 2.2A and 2.2B specifications. It supports automatic baud-rate detection, checksum generation (classic and enhanced), frame error detection, and slave node response timing control-all implemented in hardware without CPU intervention. The R5F113MLCLFB#55 routes LIN signals through P10/P11 pins and requires only an external LIN transceiver for physical layer compliance.

What is the RTC accuracy specification for the R5F113MLCLFB#55?

The R5F113MLCLFB#55 RTC achieves ±1.5 ppm accuracy at 25°C when using a standard 32.768 kHz tuning-fork crystal under stable temperature conditions. Accuracy degrades to ±5 ppm over the full −40°C to +85°C range. The R5F113MLCLFB#55 includes automatic temperature-compensation registers and supports external calibration via its RTC trim register (RTCCR), enabling field adjustment to maintain ±2 ppm stability in production units.

Can the R5F113MLCLFB#55 operate from a single 3.0 V lithium coin cell?

Yes, the R5F113MLCLFB#55 operates across 1.6 V to 5.5 V, making it compatible with 3.0 V lithium coin cells (e.g., CR2032) across full temperature and load conditions. In halt mode with RTC active, the R5F113MLCLFB#55 draws ≤0.35 μA, enabling multi-year operation. Its internal voltage regulator maintains stable core voltage down to 1.6 V, and the RTC continues functioning even during brown-out events below 1.8 V.

Is there on-chip EEPROM in the R5F113MLCLFB#55?

No, the R5F113MLCLFB#55 does not include dedicated EEPROM memory. However, it provides 8 KB of data flash memory (separate from program flash) with 100k write/erase endurance and hardware ECC, configured as emulated EEPROM via Renesas' Flash Self-Programming Library (FSPL). This data flash area is used by the R5F113MLCLFB#55 for storing calibration constants, event logs, and RTC alarm settings with guaranteed data retention for 20 years at 85°C.
