Overview
R5F104LHAFP#10 from Renesas is a 64-pin LQFP-0.65mm, 128 KB flash, 16 KB RAM RL78/G14 16-bit microcontroller with ultra-low power operation (66 μA/MHz), integrated 10-bit ADC (20 channels), RTC, and dual UART/LIN interfaces - deployed in industrial motor control and sensor node firmware.
For engineers reviewing the R5F104LHAFP#10 datasheet, R5F104LHAFP#10 pinout, R5F104LHAFP#10 application, or R5F104LHAFP#10 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +85°C industrial temperature grade (D), 128 KB code flash with data flash shield window, and support for background data flash rewriting (BGO) at VDD = 1.8–5.5 V.
Technical Context
The R5F104LHAFP#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (@32 MHz high-speed oscillator) to 30.5 µs (@32.768 kHz subsystem clock). It integrates Event Link Controller (ELC) for hardware-triggered peripheral chaining and Data Transfer Controller (DTC) with block/chain transfer modes activated by 19–26 event sources.
Its analog subsystem includes an 8/10-bit ADC with internal 1.45 V reference and temperature sensor, plus two 8-bit DAC channels with real-time output capability and selectable 0–VDD output range. Power management features HALT, STOP, and SNOOZE modes, with 0.60 μA RTC+LVD-only operation.
