Product details
Overview
R5F104LLALA#U0 from Renesas is a 64-pin FLGA-packaged RL78/G14 16-bit MCU with 512 KB flash, 32 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40°C to +105°C (G-grade), delivering 44 DMIPS at 32 MHz for industrial control, sensor nodes, and low-power HMI applications.
For engineers reviewing the R5F104LLALA#U0 datasheet, R5F104LLALA#U0 pinout, R5F104LLALA#U0 application, or R5F104LLALA#U0 equivalent, key selection criteria include its 64-pin 5×5 mm FLGA package, integrated RTC with calendar support, ultra-low-power STOP mode (0.60 μA), and hardware-based event linking via ELC for deterministic peripheral coordination.
Technical Context
The R5F104LLALA#U0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions within a 1 MB address space. It integrates a Data Transfer Controller (DTC) with chain transfer and background operation during data flash rewriting.
Its peripheral set includes up to 12-channel 16-bit Timer Array Unit (TAU), real-time clock with alarm/calendar, 10-bit 20-channel ADC with internal reference and temperature sensor, and serial interfaces including 4–10-channel I²C, 3–4-channel UART/LIN, and 3–8-channel CSI (SPI-compatible). Event Link Controller (ELC) enables direct hardware-triggered peripheral activation without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LKALA#U0 | Same FLGA-64 package, 384 KB flash, 24 KB RAM, 8 KB data flash | Suitable where reduced code size suffices and lower cost is prioritized | Select when full 512 KB flash is unnecessary and BOM cost optimization is critical |
| R5F104LLAFB#30 | Same 512 KB/32 KB/8 KB memory, but 64-pin LFQFP (10×10 mm, 0.5 mm pitch) | Preferred for through-hole prototyping or legacy LQFP-based designs | Choose when board layout rework is impractical and thermal performance permits larger footprint |
Compared with R5F104LLALA#U0, R5F104LKALA#U0 trades 128 KB flash and 8 KB RAM for lower unit cost, while R5F104LLAFB#30 retains identical memory and peripherals but replaces FLGA's compactness with LFQFP's assembly familiarity - both require distinct PCB footprints and thermal design considerations.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104LLALA#U0?
The R5F104LLALA#U0 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, validated under typical conditions (VDD = 3.3 V, TA = 25°C). The high-speed on-chip oscillator supports selectable frequencies from 1 MHz to 64 MHz, with ±1.0% accuracy across the full voltage and temperature range.
Does the R5F104LLALA#U0 support hardware-based CRC calculation, and if so, which protocols does it accelerate?
Yes, the R5F104LLALA#U0 includes a dedicated hardware CRC generator supporting configurable polynomial widths (16- or 32-bit) and initial/final XOR values. It accelerates CRC-16-CCITT for Modbus RTU, CRC-32 for firmware image integrity checks, and custom polynomials used in proprietary sensor communication stacks - all without CPU intervention or additional memory overhead.
How many analog input channels and what ADC resolution does the R5F104LLALA#U0 provide?
The R5F104LLALA#U0 provides a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), including dedicated AVREFP/AVREFM pins for precision referencing. It integrates an internal 1.45 V reference and on-die temperature sensor, enabling calibrated measurements across the full -40°C to +105°C operating range without external components.
What power-saving modes are available on the R5F104LLALA#U0, and what is the lowest achievable current draw?
The R5F104LLALA#U0 offers HALT, STOP, and SNOOZE modes. Its lowest operational current is 0.60 μA in STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active - verified at VDD = 3.0 V and TA = 25°C. This enables multi-year battery operation in metering and remote sensor applications where periodic wake-up is required.
Is the R5F104LLALA#U0 pin-compatible with other RL78/G14 variants in the same FLGA-64 package?
Yes, all RL78/G14 devices in the 64-pin FLGA package (e.g., R5F104LKALA#U0, R5F104LLALA#U0) share identical pinouts and electrical characteristics. Memory size, peripheral enablement, and operating temperature grade differ by part number, but PCB layout, decoupling, and signal routing remain fully interchangeable - enabling scalable design reuse across performance tiers.
