Product details
Overview
R5F104LLGLA#W0 from Renesas is a 64-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 512 KB flash, 8 KB data flash, and 48 KB RAM, operating at 32 MHz (44 DMIPS), supporting ultra-low-power modes (0.60 μA RTC+LVD), 10-bit ADC (20 channels), dual DAC, and multiple serial interfaces including UART, I²C, and CSI for embedded control in industrial temperature range (−40°C to +105°C).
For engineers reviewing the R5F104LLGLA#W0 datasheet, R5F104LLGLA#W0 pinout, R5F104LLGLA#W0 application, or R5F104LLGLA#W0 equivalent, key selection criteria include its 64-pin HWQFN-0.5mm package, industrial-grade −40°C to +105°C operation (G-grade), integrated real-time clock with calendar, background data flash rewriting (BGO), and event-link controller (ELC) for deterministic peripheral triggering.
Technical Context
The R5F104LLGLA#W0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode), and includes multiply/divide/accumulate instructions. Its memory subsystem integrates 512 KB code flash (1 KB block size), 8 KB data flash (1M rewrite cycles), and 48 KB SRAM - all accessible within a 1 MB address space.
Peripheral integration includes Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, calendar-capable RTC, watchdog timer, 10-bit ADC with internal reference and temperature sensor, two 8-bit DACs, up to 26-event ELC routing, and Data Transfer Controller (DTC) supporting chain transfers - enabling deterministic, low-CPU-overhead real-time control.
