Product details
Overview
R5F104GHANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G14 microcontroller with 128 KB flash, 16 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C (industrial G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (16 ch), and RTC with calendar.
For engineers reviewing the R5F104GHANA#U0 datasheet, R5F104GHANA#U0 pinout, R5F104GHANA#U0 application, or R5F104GHANA#U0 equivalent, key selection criteria include industrial-temperature operation, on-chip debug support, self-programmable flash with boot swap, background data flash rewriting, and hardware event linking via ELC for deterministic real-time control in resource-constrained embedded systems.
Technical Context
The R5F104GHANA#U0 implements the RL78 CPU core with a 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 128 KB code flash (1 KB block size), 8 KB data flash with 1M rewrite cycles, and 16 KB SRAM - with flash library RAM usage starting at FE900H.
Peripherals are orchestrated via Event Link Controller (ELC) enabling direct hardware-triggered peripheral activation without CPU intervention, and Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes with chain functionality. Power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with interrupt/reset options.
