Overview
R5F104ADASP#30 from Renesas is a 30-pin LSSOP-packaged RL78/G14 16-bit microcontroller with 48 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), featuring ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), 32 MHz max CPU speed (44 DMIPS), and integrated peripherals including 10-bit ADC (16 channels), UART/SPI/I²C interfaces, RTC, and watchdog timer - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104ADASP#30 datasheet, R5F104ADASP#30 pinout, R5F104ADASP#30 application, or R5F104ADASP#30 equivalent, key selection considerations include its 30-pin LSSOP-0.65mm package, industrial temperature rating (D-suffix), 48 KB code flash capacity, real-time clock with calendar function, and support for background data flash rewriting - critical for firmware-upgradable embedded systems requiring long-term reliability and low standby current.
Technical Context
The R5F104ADASP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-power mode), and includes multiply/divide/accumulate instructions with 1 MB address space. It integrates a configurable Data Transfer Controller (DTC) and Event Link Controller (ELC) enabling autonomous peripheral coordination without CPU intervention.
Its mixed-signal subsystem includes an 8/10-bit ADC with internal 1.45 V reference and temperature sensor, dual-channel 8-bit DAC with real-time output, up to two comparators with window/high-speed/low-speed modes, and a 12-bit interval timer alongside a full-featured RTC with alarm and clock correction - all powered by a single 1.6–5.5 V supply with on-chip POR and 14-level LVD.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104ADASP#30?
The R5F104ADASP#30 achieves a maximum CPU frequency of 32 MHz using the high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. This is measured under standard conditions (VDD = 1.8–5.5 V, TA = -40 to +85°C) and reflects actual integer instruction throughput - not theoretical peak - making it suitable for deterministic real-time control tasks in the R5F104ADASP#30-based designs.
Does the R5F104ADASP#30 support background data flash rewriting while executing application code?
Yes, the R5F104ADASP#30 supports Background Operation (BGO) for data flash, allowing the CPU to fetch and execute instructions from program memory while simultaneously rewriting data flash sectors. This capability is essential for seamless firmware updates and parameter storage in live systems - a confirmed feature of the R5F104ADASP#30 per Renesas R01DS0053EJ0370 datasheet Section 1.1.
What are the analog peripheral resources integrated into the R5F104ADASP#30?
The R5F104ADASP#30 integrates a 10-bit successive-approximation ADC with 16 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor; two 8-bit DAC channels with 0–VDD output range and real-time update capability; and up to two comparators with selectable reference sources (internal or external) and window/high-speed/low-speed operating modes - all confirmed in the R5F104ADASP#30 datasheet Sections 1.1 and 1.3.1.
Is the R5F104ADASP#30 pin-compatible with other RL78/G14 variants in the same 30-pin LSSOP package?
Yes, all RL78/G14 30-pin LSSOP variants - including R5F104AAASP#30 through R5F104AGASP#30 - share identical pin configuration, electrical characteristics, and mechanical footprint per Figure 1-1 and Table 1-1 in the R01DS0053EJ0370 datasheet. The R5F104ADASP#30 maintains full pin-to-pin compatibility within this family, enabling memory-scaling upgrades without PCB redesign.
What industrial temperature range does the 'D' suffix in R5F104ADASP#30 indicate?
The 'D' suffix in R5F104ADASP#30 specifies industrial temperature grade operation from -40°C to +85°C, validated across the full voltage range (1.6–5.5 V). This rating is explicitly defined in Section 1.2 "Ordering Information" of the R01DS0053EJ0370 datasheet and applies to all functional blocks - CPU, flash, ADC, timers, and I/O - ensuring reliable operation in factory automation, building controls, and outdoor equipment where ambient extremes occur.
