Product details
Overview
R5F113THLFB#V0 from Renesas Electronics is a 16-bit RL78/F15 microcontroller featuring 128 KB flash memory, 10 KB RAM, and 4 KB data flash with EEPROM emulation. It operates at up to 32 MHz, supports 1.6–5.5 V supply, and integrates 12-bit ADC (24 channels), 16-bit timer arrays, and LIN/UART/I²C interfaces. It targets automotive body electronics, industrial sensors, and smart home control units requiring functional safety support.
For engineers reviewing the R5F113THLFB#V0 datasheet, R5F113THLFB#V0 pinout, R5F113THLFB#V0 application, or R5F113THLFB#V0 equivalent, this page delivers verified electrical specs, package mapping to LQFP-48, confirmed peripheral integration (ADC, timers, serial interfaces), and real-world use context for embedded control selection.
Technical Context
The R5F113THLFB#V0 implements the RL78 CPU core with 3-stage pipeline and low-power SNOOZE mode, enabling sub-μA standby current. Its on-chip voltage regulator supplies internal logic at 1.8 V, while independent EVDD/EVSS pins isolate analog circuitry for ADC stability.
It features dual watchdog timers (independent and windowed), hardware CRC calculation unit, and memory protection unit (MPU) supporting region-based access control-key for ASIL-B–aligned system design in automotive and industrial applications.
