Product details
Overview
R5F104LCALA#U0 from Renesas is a 64-pin FLGA-packaged 16-bit RL78/G14 microcontroller with 16 KB flash, 2.5 KB RAM, and industrial-grade -40°C to +105°C operation. It integrates 8-channel 10-bit ADC, dual 8-bit DAC outputs, RTC with calendar, 12-channel 16-bit timer array, UART/LIN, I²C, CSI, and ultra-low-power HALT/STOP/SNOOZE modes for battery-powered sensor nodes and motor control interfaces.
For engineers reviewing the R5F104LCALA#U0 datasheet, R5F104LCALA#U0 pinout, R5F104LCALA#U0 application, or R5F104LCALA#U0 equivalent, key selection criteria include its 5 × 5 mm FLGA package with 0.5 mm pitch, 1.6–5.5 V single-supply operation, 66 μA/MHz active current, and support for background data flash rewriting at full VDD range (1.8–5.5 V) without CPU stall.
Technical Context
The RL78/G14 core implements a 3-stage CISC pipeline with configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz), multiply/divide/accumulate instructions, and 1 MB address space. It supports on-chip debug, boot swapping, and flash shield window protection.
Peripherals include Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/repeat/chain transfer modes, and dual independent voltage comparators with selectable internal/external reference. The high-accuracy ±1.0% on-chip oscillator covers 1–64 MHz.

The R5F104LCALA#U0 operates up to 32 MHz with a typical active current of 66 μA/MHz at VDD = 3.3 V and TA = 25°C. At full speed, this equates to ~2.1 mA total active current. Its ultra-low-power STOP mode draws only 0.60 μA with RTC and LVD enabled-critical for energy-harvesting and battery-backed systems.
Does the R5F104LCALA#U0 support in-system programming and secure flash protection?
Yes, the R5F104LCALA#U0 supports full in-system programming via on-chip debug interface and includes flash shield window protection to prevent unauthorized readout. It also allows per-block erase/write prohibition-enabling secure bootloader regions and protected parameter storage in code flash memory.
Can the R5F104LCALA#U0 operate from a single 1.8 V supply, and what peripherals remain functional?
Yes, the R5F104LCALA#U0 supports 1.6–5.5 V operation, including stable 1.8 V. At 1.8 V, all core functions, 10-bit ADC (with internal 1.45 V reference), RTC, 16-bit timers, UART, I²C, and CSI remain fully operational-enabling direct interfacing with 1.8 V logic and sensors without level shifters.
How many analog input channels and DAC outputs does the R5F104LCALA#U0 provide?
The R5F104LCALA#U0 provides 8 analog input channels (ANI0–ANI7) with 10-bit resolution and internal 1.45 V reference, plus two independent 8-bit DAC outputs (ANO0, ANO1) capable of 0–VDD analog voltage generation with real-time update capability-ideal for calibration signals and audio feedback.
Is the R5F104LCALA#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-including R5F104LCALA#U0, R5F104LEALA#U0, and R5F104LGALA#U0-share identical pinouts, electrical characteristics, and peripheral mappings. This enables seamless migration across memory configurations without PCB redesign or firmware changes.
