Product details
Overview
R5F104BDANA#U0 from Renesas is a 32-pin HWQFN-packaged 16-bit RL78/G14 microcontroller designed for industrial embedded control. It integrates 32 KB flash memory, 4 KB data flash, 4 KB RAM, 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 battery-powered sensors and motor-control interfaces.
For engineers reviewing the R5F104BDANA#U0 datasheet, R5F104BDANA#U0 pinout, R5F104BDANA#U0 application, or R5F104BDANA#U0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.5 mm pitch) footprint, industrial-grade −40 to +85°C operation (D-suffix), integrated 10-bit ADC with 8 channels, dual UART/LIN support, and hardware DTC/ELC for deterministic real-time peripheral coordination.
Technical Context
The R5F104BDANA#U0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode), plus multiply/divide/accumulate instructions and 1 MB address space. It features a configurable high-accuracy on-chip oscillator (±1.0% over −20 to +85°C) with selectable frequencies from 1–64 MHz.
Its peripheral set includes an Event Link Controller (ELC) enabling direct hardware-triggered peripheral activation (19–26 event types), a Data Transfer Controller (DTC) supporting normal/repeat/block transfers with chain functionality, and a Real-Time Clock with calendar, alarm, and clock correction - all optimized for deterministic low-latency response in resource-constrained industrial nodes.

FAQ
What is the maximum operating frequency and core performance of the R5F104BDANA#U0?
The R5F104BDANA#U0 operates at up to 32 MHz and delivers 44 DMIPS using the RL78 16-bit CISC core with 3-stage pipeline. Its minimum instruction execution time is 0.03125 μs in high-speed mode, enabling deterministic real-time control loops with sub-100 μs latency - verified in the R01DS0053EJ0340 datasheet Section 1.1.
Does the R5F104BDANA#U0 support in-application programming (IAP) of its flash memory?
Yes, the R5F104BDANA#U0 supports self-programming of both code and data flash memory with boot swap and flash shield window functions. It uses on-chip RAM starting at FE900H for flash library operations, allowing safe firmware updates without external memory - confirmed in Section 1.1 and memory map tables of R01DS0053EJ0340.
What are the analog input capabilities of the R5F104BDANA#U0?
The R5F104BDANA#U0 integrates a 10-bit A/D converter with 8 analog input channels (ANI0–ANI7), internal 1.45 V reference voltage, and temperature sensor. It operates across the full 1.6–5.5 V supply range and supports differential measurements via AVREFP/AVREFM pins - detailed in Section 1.1 "A/D Converter" of R01DS0053EJ0340.
How does the R5F104BDANA#U0 achieve ultra-low power consumption in STOP mode?
The R5F104BDANA#U0 achieves 0.60 μA in STOP mode by retaining only RTC and LVD functionality while shutting down the CPU, flash, and most peripherals. This state is entered via software command and exited by RTC alarm or external interrupt - specified in Section 1.1 "Ultra-Low Power Consumption Technology" of R01DS0053EJ0340.
Is the R5F104BDANA#U0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 32-pin HWQFN package (e.g., R5F104BAANA#U0, R5F104BCANA#U0, R5F104BDANA#U0) share identical pinouts and electrical characteristics. Memory size and peripheral enablement vary by part number, but PCB layout and signal routing remain fully interchangeable - confirmed in Table 1-1 and Pin Configuration diagrams of R01DS0053EJ0340.
