Product details
Overview
R5F104LDGFP#V0 from Renesas is a 64-pin LFQFP-packaged 16-bit RL78/G14 microcontroller with 32 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V at -40 to +85°C (industrial grade D), delivering 44 DMIPS at 32 MHz while consuming only 66 μA/MHz active current and 0.60 μA in RTC+LVD-only mode - deployed in industrial sensor nodes and low-power HMI controllers.
For engineers reviewing the R5F104LDGFP#V0 datasheet, R5F104LDGFP#V0 pinout, R5F104LDGFP#V0 application, or R5F104LDGFP#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm pitch package, integrated 10-bit 20-channel ADC with temperature sensor, dual UART/LIN support, and hardware DTC/ELC for deterministic peripheral event handling in resource-constrained embedded systems.
Technical Context
The R5F104LDGFP#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), plus multiply/divide/accumulate instructions and 1 MB address space. It integrates a configurable high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable).
Peripheral subsystems include Timer Array Unit (TAU) with up to 8 channels, Real-Time Clock with calendar/alarm/correction, 12-bit interval timer, watchdog timer, and Event Link Controller (ELC) enabling direct hardware linking of 19–26 event sources to peripherals without CPU intervention - critical for deterministic low-latency response in industrial control loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LEAFP#V0 | Same 64-pin LQFP package, but 48 KB flash, 5.5 KB RAM, 8 KB data flash | Higher firmware headroom for OTA updates and larger protocol stacks (e.g., full Modbus TCP) | Select when future firmware expansion or additional peripheral drivers require >32 KB code space |
| R5F104LDGFP#30 | Identical electrical specs and pinout, but packaged in embossed tape (#30) instead of tray (#V0) | No functional difference; suited for automated SMT line feeding vs. manual/hand-solder prototyping | Choose #30 for high-volume production; #V0 for evaluation, small-batch, or repair inventory |
Compared with R5F104LEAFP#V0, the R5F104LDGFP#V0 trades flash/RAM capacity for lower cost and smaller memory footprint - ideal for fixed-function devices; compared with R5F104LDGFP#30, it offers identical performance but optimized for flexible procurement and bench-level use.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104LDGFP#V0?
The R5F104LDGFP#V0 operates up to 32 MHz with 44 DMIPS performance and consumes 66 μA per MHz in active mode. At full speed, typical active current is ~2.1 mA (32 MHz × 66 μA/MHz). Its ultra-low-power STOP mode draws just 0.60 μA when only RTC and LVD remain active - verified per R01DS0053EJ0340 Rev. 3.40, Section 1.1.
Does the R5F104LDGFP#V0 support hardware debugging and in-circuit programming?
Yes, the R5F104LDGFP#V0 includes an on-chip debug function compatible with Renesas E2 emulator and E2 studio IDE. It supports full SWD-based debugging, flash programming, and real-time trace via dedicated TOOL0/TOOLRxD/TOOLTxD pins - no external debugger hardware required beyond standard JTAG/SWD interface.
How many serial communication interfaces does the R5F104LDGFP#V0 integrate, and what protocols are supported?
The R5F104LDGFP#V0 integrates three UART channels (all LIN-bus capable), up to ten I²C/simplified I²C channels, and up to eight CSI (SPI-compatible) channels. Each interface supports independent clocking, hardware flow control, and multi-master arbitration - enabling concurrent communication with sensors, displays, and host controllers without software overhead.
What is the flash memory organization and write endurance of the R5F104LDGFP#V0?
The R5F104LDGFP#V0 contains 32 KB of code flash memory organized in 1 KB blocks, and 4 KB of data flash memory. Data flash supports background operation (BGO) and guarantees 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V - sufficient for daily logging over 27 years. Code flash supports self-programming with boot swap for safe firmware updates.
Can the R5F104LDGFP#V0 operate from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F104LDGFP#V0 operates across 1.6–5.5 V, including 1.8 V nominal supply. At 1.8 V, all core functions, 10-bit ADC (with internal 1.45 V reference), RTC, 16-bit timers, UART/LIN, I²C, and GPIO remain fully operational - validated per datasheet Section 1.1 and electrical characteristics tables in R01DS0053EJ0340.
