Product details
Overview
R5F104LEGFP#10 from Renesas is a 48-pin LFQFP, 512 KB flash, 48 KB RAM RL78/G14 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in industrial motor control and sensor-based HMI systems.
For engineers reviewing the R5F104LEGFP#10 datasheet, R5F104LEGFP#10 pinout, R5F104LEGFP#10 application, or R5F104LEGFP#10 equivalent, key selection criteria include its 512 KB code flash with 1 KB block erase, dual 8-channel 16-bit timers (TAU), integrated RTC with calendar/alarm, 20-channel 10-bit ADC, and LIN-capable UARTs for deterministic real-time embedded control.
Technical Context
The R5F104LEGFP#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 19–26 event sources via the Event Link Controller (ELC).
Its analog subsystem includes an 8/10-bit ADC with 20 input channels, internal 1.45 V reference and temperature sensor, plus two 8-bit DAC outputs (0–VDD range) with real-time update capability. Power management features HALT, STOP, and SNOOZE modes, on-chip POR, and 14-level LVD with interrupt/reset options.
