Product details
Overview
R5F104LDDFA#V0 from Renesas is a 64-pin LFQFP, 512 KB flash, 8 KB data flash, 24 KB RAM RL78/G14 16-bit microcontroller operating from 1.6 V to 5.5 V with 66 μA/MHz active current and 0.60 μA RTC+LVD standby mode, used in industrial motor control and sensor interface modules.
For engineers reviewing the R5F104LDDFA#V0 datasheet, R5F104LDDFA#V0 pinout, R5F104LDDFA#V0 application, or R5F104LDDFA#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, industrial-grade −40°C to +85°C operation (D-suffix), integrated 10-bit 20-channel ADC, real-time clock with calendar, and hardware event link controller for deterministic peripheral triggering.
Technical Context
The R5F104LDDFA#V0 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), and includes multiply/divide/accumulate instructions. It integrates a Data Transfer Controller (DTC) with chain transfer and block modes activated by 19–26 event sources via the Event Link Controller (ELC).
It features dual-clock domain operation: high-speed on-chip oscillator (selectable 1–64 MHz, ±1.0% accuracy) and subsystem clock (32.768 kHz), enabling ultra-low-power STOP/HALT/SNOOZE modes. Peripheral integration includes UART/LIN (4 channels), CSI (up to 8 channels), I²C (up to 10 channels), 12-channel 16-bit TAU timer, and 1-channel 12-bit interval timer.

| Energy Metering Interface | Industrial PLC I/O Module |
Use Scenario: Isolated front-end interface between metrology ICs (e.g., ADE7953) and main PLC controller in DIN-rail energy meters. IC Role / Device Role / Timing Role: SPI master (CSI) to read metrology registers, process RMS/energy values, and report via UART or I²C to host. Use Value: Hardware CRC generator and ELC-linked ADC triggers ensure deterministic, cycle-accurate sampling aligned to AC line period-critical for Class 0.5 metering compliance. | Use Scenario: Digital input/output expansion module for modular PLC systems requiring galvanically isolated 24 V DC I/O handling.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F104LDDFA#V0?
The R5F104LDDFA#V0 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.0 V and TA = 25°C. At full 32 MHz operation, total active current is approximately 2.1 mA. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 64 MHz, though 32 MHz is the rated maximum for this device grade.
Does the R5F104LDDFA#V0 support in-system programming and secure firmware updates?
Yes, the R5F104LDDFA#V0 supports full in-system programming via its single-pin TOOL0 interface using Renesas Flash Programmer. It includes flash shield window protection, block erase prohibition, and boot swap functionality-enabling secure field updates without exposing sensitive code regions or risking corruption during power loss.
How many serial communication interfaces does the R5F104LDDFA#V0 integrate, and what protocols are supported?
The R5F104LDDFA#V0 integrates up to four UART channels (with LIN bus support), eight CSI channels (functionally equivalent to SPI), and ten I²C/simplified I²C channels. All are independently configurable, and UARTs support automatic LIN header detection and checksum generation-critical for automotive and industrial networked sensors.
What is the purpose of the REGC pin on the R5F104LDDFA#V0, and how must it be connected?
The REGC pin on the R5F104LDDFA#V0 is the bypass capacitor terminal for the internal voltage regulator. It must be connected to VSS using a 0.47 μF to 1.0 μF ceramic capacitor placed as close as possible to the pin. Failure to do so risks unstable operation, especially during mode transitions or high-current peripheral activity.
Can the R5F104LDDFA#V0 operate from a 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F104LDDFA#V0 operates across 1.6 V to 5.5 V. At 1.8 V, all core functions-including 10-bit ADC (with internal 1.45 V reference), RTC, 16-bit timers, UART, CSI, and I²C-remain fully operational. The high-speed oscillator is functional down to 1.8 V, enabling full-speed 32 MHz operation even at minimum supply.
