Product details
Overview
R5F104LDAFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade RL78/G14 16-bit microcontroller with 192 KB code flash, 8 KB data flash, and 20 KB RAM. It operates from 1.6–5.5 V, delivers 44 DMIPS at 32 MHz, and supports ultra-low-power modes (66 μA/MHz active, 0.60 μA RTC+LVD). It targets embedded control in motor drives, sensor nodes, and industrial HMI.
For engineers reviewing the R5F104LDAFB#30 datasheet, R5F104LDAFB#30 pinout, R5F104LDAFB#30 application, or R5F104LDAFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, integrated RTC + LVD + 10-bit ADC (20-channel), UART/SPI/I²C interface count, and industrial temperature range (−40 to +85°C).
Technical Context
The R5F104LDAFB#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 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 reference (1.45 V) and temperature sensor, dual 8-bit D/A channels with real-time output, and two analog comparators configurable in high-speed, low-speed, or window mode - all operating across the full 1.6–5.5 V supply range.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F104LDAFB#30?
The R5F104LDAFB#30 achieves a maximum operating frequency of 32 MHz with a measured performance of 44 DMIPS. This rating is based on the RL78 CPU core's 3-stage pipeline architecture and verified under standard test conditions per Renesas documentation. The R5F104LDAFB#30 maintains this performance across its full 1.6–5.5 V supply range and −40 to +85°C industrial temperature grade.
Does the R5F104LDAFB#30 support background data flash rewriting while executing code from main flash?
Yes, the R5F104LDAFB#30 supports Background Operation (BGO) for data flash rewriting. During BGO, the CPU can execute instructions from program memory while the data flash is being rewritten - enabling seamless firmware parameter updates or logging without system interruption. This capability is confirmed in the RL78/G14 datasheet and applies directly to the R5F104LDAFB#30 variant.
What are the analog reference voltage options available for the 10-bit ADC in the R5F104LDAFB#30?
The R5F104LDAFB#30 ADC supports two reference voltage sources: the internal 1.45 V reference (VREF) and the externally supplied AVREFP/AVREFM differential pair. The internal reference is factory-trimmed and stable across temperature, while the external reference allows flexible scaling for precision measurements. Both options are selectable per-channel via register configuration and apply to all 20 analog input channels of the R5F104LDAFB#30.
Is the R5F104LDAFB#30 pin-compatible with other RL78/G14 variants in the same 64-pin LFQFP package?
Yes, the R5F104LDAFB#30 is fully pin-compatible with all other RL78/G14 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F104LEAFB#30, R5F104LHAFB#30), sharing identical pin functions, electrical characteristics, and mechanical footprint. This compatibility enables memory-size-based scalability without PCB redesign - a documented feature of the RL78/G14 family architecture.
What industrial temperature grade does the R5F104LDAFB#30 support, and how is it indicated in the part number?
The R5F104LDAFB#30 supports the industrial temperature grade of −40 to +85°C, denoted by the "D" in the fourth character position of the part number (R5F104DLAFB#30). This grade is validated per Renesas qualification standards and applies across all specified operating voltages and peripheral functions. The "D" suffix explicitly differentiates it from consumer ("A") and extended industrial ("G", −40 to +105°C) variants.
