It integrates a 32 MHz max CPU clock, 12-bit ADC with 24 channels, 8-bit D/A converter, and supports LIN bus communication - deployed in automotive body control modules for window lift and seat position control.
For engineers reviewing the R5F113TLKFB#H5 datasheet, R5F113TLKFB#H5 pinout, R5F113TLKFB#H5 application, or R5F113TLKFB#H5 equivalent, this page delivers verified electrical specs, validated pin functions for 64-pin LQFP, automotive-grade peripheral integration (LIN, ADC, D/A), and direct alternative part comparisons aligned to RL78/F15 family documentation.
Technical Context
The R5F113TLKFB#H5 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V operation and −40°C to +105°C ambient range. It includes on-chip debug functionality, low-power modes (HALT, STOP, SNOOZE), and hardware multiplier/divider for real-time motor control math.
Peripherals are tightly coupled to the bus matrix: the 12-bit ADC supports simultaneous sampling across up to 4 channels via hardware trigger, while the LIN controller complies with ISO 17987-4:2016 and supports auto-baud detection and checksum generation without CPU intervention.
