Product details
Overview
R5F104LCAFA#30 from Renesas is a 64-pin LQFP-0.65mm 16-bit RL78/G14 microcontroller with 192 KB flash, 20 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40°C to +85°C (industrial grade D). It integrates 12-bit ADC (16 channels), UART/SCI ×3, I²C ×4, 16-bit timers ×10, RTC, and ultra-low-power HALT/STOP/SNOOZE modes for battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F104LCAFA#30 datasheet, R5F104LCAFA#30 pinout, R5F104LCAFA#30 application, or R5F104LCAFA#30 equivalent, key selection criteria include its 192 KB code flash size, 64-pin LQFP-0.65 mm package, industrial temperature rating (D-grade), integrated 12-bit ADC with 16 inputs, and support for background data flash rewriting (BGO) in real-time systems.
Technical Context
The R5F104LCAFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (@32 MHz) to 30.5 µs (@32.768 kHz). It features event-driven peripheral control via Event Link Controller (ELC) and autonomous data movement using Data Transfer Controller (DTC), enabling low-CPU-load sensor acquisition and communication handling.
Its power management includes on-chip POR, 14-level LVD with interrupt/reset options, and multiple low-power modes: HALT (66 µA/MHz), STOP (0.60 µA with RTC+LVD active), and SNOOZE mode for selective peripheral wake-up-critical for energy-constrained edge devices requiring long battery life without sacrificing responsiveness.

FAQ
What is the maximum operating frequency and associated performance of the R5F104LCAFA#30?
The R5F104LCAFA#30 operates up to 32 MHz with a measured performance of 44 DMIPS. Its high-accuracy on-chip oscillator maintains ±1.0% tolerance across 1.8–5.5 V and -20 to +85°C, eliminating need for external crystal in many applications. The RL78 core's 3-stage pipeline enables consistent instruction throughput even at ultra-low speeds (e.g., 32.768 kHz for RTC).
Does the R5F104LCAFA#30 support in-system programming and debug without external tools?
Yes, the R5F104LCAFA#30 includes an integrated FINE v2 on-chip debug interface supporting full SWD-based programming, real-time trace, breakpoint setting, and flash erase/write-all via a standard 6-pin debug connector. No external emulator is required for development or field firmware updates.
How many analog input channels does the R5F104LCAFA#30 support, and what ADC resolution is available?
The R5F104LCAFA#30 integrates a 12-bit successive-approximation ADC with up to 16 analog input channels (ANI0–ANI15), selectable across multiple port pins. It includes internal 1.45 V reference and temperature sensor, enabling accurate sensor measurements without external components in industrial environments.
What low-power modes are available on the R5F104LCAFA#30, and what is the lowest achievable current draw?
The R5F104LCAFA#30 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.60 µA-verified across -40°C to +85°C. HALT mode consumes 66 µA/MHz, and SNOOZE allows selective peripheral operation (e.g., ADC conversion) while CPU remains halted, optimizing dynamic power efficiency.
Is the R5F104LCAFA#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 64-pin LQFP-0.65 mm package-including R5F104LCAFA#30, R5F104LDAFA#30, and R5F104LEAFA#30-share identical pinouts and electrical characteristics. This enables seamless migration between memory configurations without PCB redesign or layout changes.
