Product details
Overview
R5F104LDAFP#30 from Renesas is a 64-pin LQFP-0.65 mm pitch, industrial-grade (D) 16-bit RL78/G14 microcontroller with 192 KB flash, 20 KB RAM, and 8 KB data flash. It operates from 1.6–5.5 V, delivers 44 DMIPS at 32 MHz, and supports ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD). Used in motor control, sensor hubs, and industrial HMI.
For engineers reviewing the R5F104LDAFP#30 datasheet, R5F104LDAFP#30 pinout, R5F104LDAFP#30 application, or R5F104LDAFP#30 equivalent, key selection criteria include its 64-pin LQFP package, 192 KB code flash with block erase security, integrated 10-bit 20-channel ADC, real-time clock with calendar, and dual UART/LIN support for deterministic serial communication in resource-constrained embedded systems.
Technical Context
The R5F104LDAFP#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 integrates a Data Transfer Controller (DTC) for autonomous memory transfers and an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its mixed-signal subsystem includes a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, dual 8-bit D/A channels with real-time output, two comparators with window mode, and a 12-bit interval timer plus calendar-mode RTC - all operating across the full −40°C to +85°C industrial temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LEAFP#30 | Same 64-pin LQFP package, but 48 KB flash, 5.5 KB RAM, 4 KB data flash - lower memory capacity and no RTC calendar mode | Targeted at simpler control tasks without long-term timekeeping or large firmware; lacks calendar RTC and BGO data flash | Select when firmware size < 48 KB and calendar/time-stamping is unnecessary - reduces cost without sacrificing pin compatibility |
| R5F104LGAFP#30 | Same 64-pin LQFP, 128 KB flash, 16 KB RAM, 8 KB data flash - 64 KB less code flash than R5F104LDAFP#30 | Optimized for mid-complexity applications requiring RTC and BGO but not full 192 KB firmware footprint | Choose for balanced cost/performance where 128 KB flash suffices - retains all analog peripherals and ELC functionality |
Compared with R5F104LEAFP#30 and R5F104LGAFP#30, the R5F104LDAFP#30 provides 192 KB flash and 20 KB RAM for larger firmware (e.g., Modbus TCP stack + OTA), full calendar RTC for billing/metering, and higher ADC channel count - making it optimal for feature-rich industrial edge nodes where memory headroom and precision timekeeping are critical.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104LDAFP#30?
The R5F104LDAFP#30 operates at up to 32 MHz with a measured performance of 44 DMIPS. This is achieved using the high-speed on-chip oscillator (±1.0% accuracy) and the RL78 CPU's 3-stage pipeline. The R5F104LDAFP#30 maintains this performance across its full industrial temperature range (−40°C to +85°C) and supply voltage (1.6–5.5 V), making it suitable for timing-critical control loops in motor drives and power converters.
Does the R5F104LDAFP#30 support real-time clock functionality with calendar mode?
Yes, the R5F104LDAFP#30 includes a dedicated real-time clock (RTC) peripheral with full calendar mode supporting year/month/day/hour/minute/second tracking for up to 99 years, alarm interrupts, and automatic clock correction. This RTC operates independently in STOP mode with only 0.60 μA current draw when paired with the on-chip LVD, enabling precise timekeeping in smart meters and data loggers powered by coin cells or energy harvesting.
What are the flash memory configuration details for the R5F104LDAFP#30?
The R5F104LDAFP#30 integrates 192 KB of on-chip code flash memory organized in 1 KB blocks, with security features including per-block erase/write prohibition. It also includes 8 KB of data flash supporting background operation (BGO), 1,000,000 write/erase cycles (typical), and reprogramming at VDD = 1.8–5.5 V. These features allow safe field firmware updates and persistent parameter storage without halting application execution - a key capability of the R5F104LDAFP#30 in industrial deployments.
How many analog-to-digital converter (ADC) channels does the R5F104LDAFP#30 provide, and what is their resolution?
The R5F104LDAFP#30 features a 10-bit successive approximation register (SAR) ADC with up to 20 input channels (ANI0–ANI19), selectable reference sources (VDD or internal 1.45 V), and integrated temperature sensor. It supports single- and continuous-conversion modes, scan sequences, and hardware triggering via the Event Link Controller (ELC). This ADC capability enables high-accuracy sensor interfacing in the R5F104LDAFP#30 for applications like motor phase current sensing and environmental monitoring.
Is the R5F104LDAFP#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, the R5F104LDAFP#30 is pin-compatible with all other RL78/G14 devices in the 64-pin LQFP-0.65 mm package (e.g., R5F104LEAFP#30, R5F104LGAFP#30), sharing identical pin functions, electrical characteristics, and mechanical footprint (PLQP0064JA-A / PLQP0064JB-A). This allows direct substitution within the same PCB layout when adjusting flash/RAM requirements - a design flexibility confirmed in Renesas' official ordering information tables for the RL78/G14 family.
