Overview
R5F113MLCKFB#35 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), designed for industrial control and sensor interface applications requiring deterministic timing and extended temperature operation.
For engineers reviewing the R5F113MLCKFB#35 datasheet, R5F113MLCKFB#35 pinout, R5F113MLCKFB#35 application, or R5F113MLCKFB#35 equivalent, this device supports up to 64 general-purpose I/O pins, 12-bit ADC with 24 channels, and hardware UART/I²C/SPI interfaces - all operating within −40°C to +105°C ambient range under single 1.8–5.5 V supply.
Technical Context
The R5F113MLCKFB#35 implements the RL78 CPU core with 3-stage pipeline, 16-bit ALU, and 16-bit address/data bus architecture. It integrates a 12-bit successive-approximation ADC with sample-and-hold, programmable gain amplifier (PGA) support on selected channels, and dual 16-bit timer arrays with complementary PWM output capability.
On-chip peripherals include a 32-bit real-time counter (RTC) with calendar function, independent watchdog timer (IWDT), data flash memory (8 KB) with EEPROM emulation, and hardware encryption accelerator supporting AES-128. All peripherals are accessible via dedicated SFRs and support interrupt-driven operation with 32 priority levels.

FAQ
What is the maximum operating frequency of the R5F113MLCKFB#35?
The R5F113MLCKFB#35 operates at a maximum CPU clock frequency of 32 MHz when using the high-speed on-chip oscillator (HOCO) or an external crystal up to 20 MHz with PLL multiplication. This frequency supports real-time control loops with sub-microsecond response times and enables full utilization of its 12-bit ADC sampling rate up to 100 kSPS.
Does the R5F113MLCKFB#35 support USB communication?
No, the R5F113MLCKFB#35 does not include a USB peripheral. It features UART, I²C, and SPI interfaces for serial communication. For USB connectivity, Renesas recommends pairing the R5F113MLCKFB#35 with an external USB-to-UART bridge IC or selecting a different RL78 family member such as the RL78/G1D that integrates USB 2.0 FS controller.
What is the data retention period for the on-chip data flash in the R5F113MLCKFB#35?
The on-chip data flash in the R5F113MLCKFB#35 guarantees 10 years of data retention at +85°C and 40 years at +25°C, based on Renesas' characterization testing. This specification applies when using the built-in EEPROM emulation firmware library, which manages wear leveling and write buffering to extend endurance beyond the base 100k cycle limit.
Can the R5F113MLCKFB#35 operate from a single 3.3 V supply?
Yes, the R5F113MLCKFB#35 fully supports operation from a single 3.3 V supply across its entire specified temperature range (−40°C to +105°C). At 3.3 V, it delivers full performance including 32 MHz CPU operation, 12-bit ADC accuracy (±1 LSB INL), and all peripheral functions - eliminating need for voltage translation in 3.3 V system designs.
Is the R5F113MLCKFB#35 qualified for automotive applications?
No, the R5F113MLCKFB#35 is rated for industrial temperature range (−40°C to +105°C) and classified as "Standard" quality grade per Renesas documentation. It is not AEC-Q100 qualified and lacks automotive-specific features such as enhanced ESD immunity or extended lifetime validation. For automotive use, Renesas offers the RL78/F14 series with AEC-Q100 Grade 2 qualification.
