Product details
Overview
R5F104LDGFP#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade RL78/G14 microcontroller with 512 KB flash, 8 KB data flash, 48 KB RAM, and -40 to +105°C operation. It delivers 44 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.60 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (20 channels), and real-time clock - deployed in motor control and smart sensor nodes.
For engineers reviewing the R5F104LDGFP#30 datasheet, R5F104LDGFP#30 pinout, R5F104LDGFP#30 application, or R5F104LDGFP#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, 512 KB code flash with block protection, dual-voltage operation (1.6–5.5 V), and integrated event link controller (ELC) for deterministic peripheral triggering without CPU intervention.
Technical Context
The R5F104LDGFP#30 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/accumulate instructions and features a 1 MB address space with four banks of 8-bit general-purpose registers.
Its power management includes HALT, STOP, and SNOOZE modes; on-chip LVD offers 14 selectable voltage detection levels with interrupt/reset options; and the Data Transfer Controller (DTC) enables background flash rewriting while executing code from program memory.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104LDGFP#30?
The R5F104LDGFP#30 operates at up to 32 MHz with 44 DMIPS performance and consumes 66 μA per MHz in active mode. At 32 MHz, typical active current is approximately 2.1 mA (VDD = 3.3 V, TA = 25°C), verified in the electrical characteristics section of the R01DS0053EJ0370 datasheet.
Does the R5F104LDGFP#30 support in-system programming and secure firmware updates?
Yes, the R5F104LDGFP#30 supports in-system programming via on-chip debug interface and includes flash shield window functionality to define protected memory regions. Self-programming with boot swapping allows safe firmware updates without erasing critical configuration data.
How many I²C interfaces does the R5F104LDGFP#30 provide, and what are their capabilities?
The R5F104LDGFP#30 provides up to 10 I²C/simplified I²C channels depending on variant configuration. Pins P60/SCLA0 and P61/SDAA0 implement one fully compliant I²C interface supporting standard (100 kHz) and fast-mode (400 kHz) operation with built-in slew-rate control and arbitration logic.
What is the purpose of the REGC pin on the R5F104LDGFP#30, and how must it be connected?
The REGC pin on the R5F104LDGFP#30 connects to an external 0.47–1 µF capacitor tied to VSS to stabilize the internal voltage regulator. This connection is mandatory per datasheet Caution notes and ensures reliable operation of the on-chip LDO supplying the core logic.
Can the R5F104LDGFP#30 operate from a 1.8 V supply, and which peripherals remain functional at that voltage?
Yes, the R5F104LDGFP#30 supports 1.6–5.5 V operation, including 1.8 V. At 1.8 V, the RL78 core, 10-bit ADC (with internal 1.45 V reference), RTC, LVD, and most GPIOs function normally; however, high-speed peripherals like 32 MHz oscillator and certain UART baud rates may be limited per the absolute maximum ratings table.
