Product details
Overview
R5F104GLGNA#U0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G14 microcontroller with 128 KB flash, 12 KB RAM, and industrial-grade -40°C to +105°C operation (G-grade). It integrates a 32 MHz RL78 CPU core delivering 44 DMIPS, ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), 10-bit 20-channel ADC, dual UART/LIN, I²C, CSI, and real-time clock - deployed in smart metering and industrial sensor nodes.
For engineers reviewing the R5F104GLGNA#U0 datasheet, R5F104GLGNA#U0 pinout, R5F104GLGNA#U0 application, or R5F104GLGNA#U0 equivalent, key selection criteria include its G-grade temperature rating, 48-pin LFQFP-0.5 mm pitch package, 128 KB flash with data flash shield window, and integrated LIN-capable UART for automotive body electronics and factory automation interfaces.
Technical Context
The R5F104GLGNA#U0 implements the RL78 CISC CPU core with 3-stage pipeline and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz), supporting multiply/divide/accumulate operations and 1 MB address space. Its power architecture enables 66 μA/MHz active current and sub-μA retention modes via dedicated LVD and POR circuits.
Peripheral integration includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/chain transfer, and background operation (BGO) for concurrent code execution during 1M-cycle-rated data flash rewriting at VDD = 1.8–5.5 V.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GLGNA#U0?
The R5F104GLGNA#U0 operates at up to 32 MHz with its RL78 CPU core, achieving 44 DMIPS performance. This is measured using the EEMBC CoreMark benchmark and reflects sustained throughput under typical code execution patterns, including branch prediction and peripheral access overhead.
Does the R5F104GLGNA#U0 support LIN bus communication, and which UART channels provide it?
Yes, the R5F104GLGNA#U0 supports LIN 2.2A protocol on UART channels 0, 1, and 2. Each channel includes dedicated hardware for break field detection, sync byte generation, and checksum calculation - enabling certified LIN master/slave operation without software bit-banging.
What is the data flash endurance and rewrite voltage range for the R5F104GLGNA#U0?
The R5F104GLGNA#U0 features 8 KB of data flash rated for 1,000,000 rewrite cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows program execution from code flash during rewrites.
How does the R5F104GLGNA#U0 achieve ultra-low-power STOP mode current of 0.60 μA?
The R5F104GLGNA#U0 achieves 0.60 μA STOP mode current by powering down all digital logic except the real-time clock (RTC) and low-voltage detector (LVD), both supplied from an optimized internal regulator. The REGC capacitor stabilizes this regulator, and no external components beyond that capacitor are required.
Is the R5F104GLGNA#U0 pin-compatible with other RL78/G14 variants in the same 48-pin LFQFP package?
Yes, the R5F104GLGNA#U0 shares identical pinout and electrical characteristics with all other RL78/G14 devices in the 48-pin LFQFP-0.5 mm pitch package (e.g., R5F104GHGNA#U0, R5F104GKGNA#U0), enabling drop-in replacement within the same memory and temperature grade family.
