It integrates 16-bit Timer Array Unit (8 channels), 10-bit ADC (16 ch), UART/SCI/LIN (4 ch), I²C (4 ch), and ultra-low-power HALT/STOP/SNOOZE modes - deployed in industrial motor control and sensor interface modules.
For engineers reviewing the R5F104LHAFA#30 datasheet, R5F104LHAFA#30 pinout, R5F104LHAFA#30 application, or R5F104LHAFA#30 equivalent, key selection criteria include its 192 KB code flash with block erase security, 10-bit ADC with internal reference and temperature sensor, and dual UART+LIN support for robust serial communication in space-constrained industrial designs.
Technical Context
The R5F104LHAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (@32 MHz) to 30.5 µs (@32.768 kHz), and includes multiply/divide/accumulate instructions. Its memory subsystem comprises 192 KB on-chip flash (1 KB blocks), 20 KB RAM, and 8 KB data flash with background operation (BGO) and 1M-cycle rewrite endurance.
Peripheral integration includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with chain transfer, and configurable I/O ports (72 total, including 10 N-ch open-drain) enabling direct interfacing with 1.8/2.5/3.3 V logic. The device supports real-time clock with calendar/alarm and watchdog timer with dedicated low-speed oscillator.
