Product details
Overview
R5F104LHAFP#30 from Renesas is a 64-pin LQFP-0.65mm-pitch, 128 KB flash, 8 KB data flash, 16 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), used in industrial sensor nodes and battery-powered HMI control.
For engineers reviewing the R5F104LHAFP#30 datasheet, R5F104LHAFP#30 pinout, R5F104LHAFP#30 application, or R5F104LHAFP#30 equivalent, key selection criteria include its 64-pin LQFP package, 128 KB code flash with self-programming and flash shield window, integrated 10-bit 20-channel ADC, real-time clock with calendar/alarm, and UART/I²C/CSI serial interfaces for embedded control systems requiring long-term power efficiency and functional safety support.
Technical Context
The R5F104LHAFP#30 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 Event Link Controller (ELC) for hardware-triggered peripheral chaining and Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by interrupts.
Its mixed-signal subsystem includes an 8/10-bit ADC with internal 1.45 V reference and temperature sensor, dual 8-bit DACs (0–VDD output), two comparators with window/high-speed/low-speed modes, and programmable I/O with N-ch open-drain, TTL input, and pull-up options-enabling direct interfacing with 1.8/2.5/3.0 V logic without level shifters.
