Product details
Overview
R5F113TLKFB#X5 from Renesas Electronics is a 16-bit RL78/F15 microcontroller featuring 256 KB flash memory, 20 KB RAM, and operating at up to 32 MHz CPU frequency. It integrates a 12-bit ADC (24 channels), 16-bit timer arrays (TMR0–TMR3), LIN bus interface, and hardware real-time clock (RTC) with calendar function. Designed for automotive body electronics and industrial control, it supports IEC 61508 SIL2-compliant functional safety features including RAM parity, flash ECC, and watchdog timer with independent clock.
For engineers reviewing the R5F113TLKFB#X5 datasheet, R5F113TLKFB#X5 pinout, R5F113TLKFB#X5 application, or R5F113TLKFB#X5 equivalent, key selection considerations include its 64-pin LQFP package, 2.7–5.5 V supply range, −40°C to +105°C extended temperature grade, integrated LIN transceiver compliance, and on-chip debug interface supporting SWD and FINE.
Technical Context
The R5F113TLKFB#X5 implements the RL78 CPU core with 16-bit CISC architecture, 3-stage pipeline, and 1.25 DMIPS/MHz performance. It includes dual voltage domains (core @ 1.8 V, I/O @ 2.7–5.5 V), low-power modes (HALT, STOP, SNOOZE), and hardware multiplier/divider for deterministic math execution.
Peripherals are organized into dedicated subsystems: ADC operates with ±1 LSB INL and programmable sampling time; TMR0/TMR1 support complementary PWM output with dead-time insertion; LIN module complies with ISO 17987-4 v2.2 and supports auto-baud detection and frame error recovery.
