It targets embedded control in industrial sensors and automotive body electronics.
For engineers reviewing the R5F113TKLFB#H5 datasheet, R5F113TKLFB#H5 pinout, R5F113TKLFB#H5 application, or R5F113TKLFB#H5 equivalent, this page delivers verified electrical specs, validated pin functions for the 48-pin LQFP variant, confirmed peripheral integration (LIN, RTC, ADC), and direct alternative part comparisons - all aligned with Renesas' official RL78/F15 Hardware Manual Rev.1.10 (Jan 2026).
Technical Context
The R5F113TKLFB#H5 implements the RL78 CPU core with 16-bit CISC architecture, supporting 100+ instructions including multiply/divide and bit manipulation. It integrates dual voltage regulators (1.8 V and 3.3 V domains), independent clock system with sub-clock (32.768 kHz), main clock (1–20 MHz crystal or 1–32 MHz external), and high-speed internal oscillator (32 MHz).
Peripheral subsystems include 24-channel 12-bit ADC with programmable sampling time, 8-bit D/A converter, 16-bit timer arrays (TAA/TAB) with dead-time insertion, 16-bit interval timer, watchdog timer, and LIN bus interface compliant with ISO 17987-4 (LIN 2.2A). All peripherals are accessible via memory-mapped I/O with priority-based interrupt vectoring.

The R5F113TKLFB#H5 supports a maximum CPU operating frequency of 32 MHz, achievable using the high-speed internal oscillator or an external crystal up to 20 MHz with PLL multiplication. This enables sub-100 ns instruction execution for time-critical control loops in motor drives and sensor fusion applications.
Does the R5F113TKLFB#H5 include hardware LIN bus support?
Yes, the R5F113TKLFB#H5 integrates a dedicated LIN controller compliant with ISO 17987-4 (LIN 2.2A), supporting automatic sync-break detection, checksum generation, and response handling without CPU intervention - reducing firmware overhead by over 70% compared to software UART implementations.
What power-saving modes are available on the R5F113TKLFB#H5?
The R5F113TKLFB#H5 offers three ultra-low-power modes: HALT (0.52 µA with RAM retention), STOP (0.37 µA with RTC running), and SNOOZE (1.2 µA with ADC active). These modes are controlled via dedicated system control registers and support wake-up on pin change, timer expiry, or peripheral interrupt.
Is the R5F113TKLFB#H5 pin-compatible with other RL78/F15 variants?
No - the R5F113TKLFB#H5 is a 48-pin LQFP device and is not pin-compatible with RL78/F15 variants in 64-, 80-, 100-, or 144-pin packages. Pin compatibility exists only within the same pin-count family (e.g., other 48-pin RL78/F15 parts), but function mapping may differ between memory/configurations.
What is the ADC resolution and channel count for the R5F113TKLFB#H5?
The R5F113TKLFB#H5 features a 12-bit successive approximation ADC with 24 input channels, configurable sampling time (1.0–12.5 µs), and built-in scan mode. It supports differential input on selected channels and hardware-triggered conversions synchronized to timer events.
