Product details
Overview
R5F104LCDFA#V0 from Renesas is a 64-pin LQFP-0.65 mm pitch, industrial-grade (D-grade) RL78/G14 16-bit microcontroller with 192 KB flash, 20 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at –40 to +85°C. It integrates a 32 MHz RL78 CPU core delivering 44 DMIPS, ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and peripherals including 12-channel 10-bit ADC, dual UART/LIN, 8-channel CSI, 10-channel I²C, and real-time clock with calendar.
For engineers reviewing the R5F104LCDFA#V0 datasheet, R5F104LCDFA#V0 pinout, R5F104LCDFA#V0 application, or R5F104LCDFA#V0 equivalent, key selection criteria include its 64-pin LQFP-0.65 mm package, industrial temperature rating, integrated DTC/ELC for low-CPU-load peripheral coordination, and support for background data flash rewriting with 1M-cycle endurance.
Technical Context
The R5F104LCDFA#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @32 MHz to 30.5 μs @32.768 kHz). It supports multiply/divide/MAC instructions and a 1 MB address space across four register banks.
Its power management includes on-chip POR, selectable 14-level LVD (interrupt/reset), and three ultra-low-power modes-HALT (CPU stop, peripherals active), STOP (all clocks off except RTC/LVD), and SNOOZE (selected peripherals operate while CPU sleeps). The high-accuracy ±1.0% on-chip oscillator supports 12 frequencies from 1 to 64 MHz.

The R5F104LCDFA#V0 operates at up to 32 MHz using the high-speed on-chip oscillator, achieving 44 DMIPS performance. Its RL78 CPU core supports configurable instruction timing - minimum execution time is 0.03125 μs at 32 MHz - and maintains functional integrity across the full 1.6–5.5 V supply range.
Does the R5F104LCDFA#V0 support in-system programming and secure firmware updates?
Yes, the R5F104LCDFA#V0 supports full in-system programming via its on-chip debug interface (TOOL0 pin) and includes flash shield window and block erase prohibition features for IP protection. Boot swap functionality enables atomic firmware updates without runtime interruption or risk of bricking.
How many analog input channels does the R5F104LCDFA#V0 ADC support, and what reference options are available?
The R5F104LCDFA#V0 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels. It supports both external references (AVREFP/AVREFM pins) and an internal 1.45 V reference voltage, enabling ratiometric measurements and eliminating need for external precision references in many sensor applications.
What low-power modes are available on the R5F104LCDFA#V0, and what is the lowest achievable current draw?
The R5F104LCDFA#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.60 μA typical at 25°C - verified per datasheet R01DS0053EJ0340. This enables decade-long battery operation in maintenance-free sensor deployments.
Is the R5F104LCDFA#V0 pin-compatible with other RL78/G14 variants in the same 64-pin LQFP package?
Yes - all RL78/G14 devices in the 64-pin LQFP-0.65 mm package (e.g., R5F104LCAFA#V0, R5F104LDAFA#V0, R5F104LEAFA#V0) share identical pinouts, electrical characteristics, and peripheral mapping. Firmware and PCB layouts are interchangeable across memory/configurations within this package group.
