Product details
Overview
R5F104BAGNA#20 from Renesas is a 32-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 96 KB flash, 12 KB RAM, and industrial-grade operation up to +105°C. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), integrated 10-bit ADC (20 channels), UART/LIN, I²C, SPI, and real-time clock - deployed in motor control, sensor nodes, and smart home appliances.
For engineers reviewing the R5F104BAGNA#20 datasheet, R5F104BAGNA#20 pinout, R5F104BAGNA#20 application, or R5F104BAGNA#20 equivalent, key selection criteria include its 32-pin 5×5 mm HWQFN package, G-grade temperature range (−40 to +105°C), on-chip debug support, and compatibility with Renesas' CS+ and e² studio toolchains for rapid firmware development.
Technical Context
The R5F104BAGNA#20 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 direct peripheral-to-peripheral signal routing without CPU intervention.
Its power architecture includes on-chip POR and LVD with 14 selectable voltage detection levels, plus dual oscillators: high-accuracy ±1.0% on-chip oscillator (1–64 MHz) and low-power subsystem clock (32.768 kHz). The device supports background data flash rewriting (1M write cycles) and secure boot swapping.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104BGANA#20 | Same 32-pin HWQFN package, identical 96 KB flash/12 KB RAM, but rated for −40 to +85°C (D grade) | Suitable for consumer-grade products where extended temperature is not required | Select when operating ambient stays ≤ +85°C and cost optimization is prioritized over industrial qualification |
| R5F104BEANA#20 | Same package and temperature grade (G), but reduced 64 KB flash and 5.5 KB RAM | Targeted at simpler control tasks with smaller firmware footprint and lower RAM usage | Choose when application firmware fits within 64 KB and requires only basic peripheral set - reduces BOM cost |
Compared with R5F104BAGNA#20, R5F104BGANA#20 trades industrial temperature margin for lower unit cost, while R5F104BEANA#20 reduces memory capacity to meet cost-sensitive designs with constrained code size - neither offers pin-to-pin replacement without validation of thermal and memory margins.

FAQ
What is the maximum operating temperature rating for the R5F104BAGNA#20?
The R5F104BAGNA#20 is rated for industrial operation from −40°C to +105°C (G-grade). This specification is confirmed in the ordering information table and applies across full voltage range (1.6–5.5 V). The device maintains timing accuracy and flash reliability within this range, validated per JEDEC JESD22-A108.
Does the R5F104BAGNA#20 support in-circuit debugging without external hardware?
Yes, the R5F104BAGNA#20 includes a full on-chip debug interface accessible via P50 (TOOLRxD) and P51 (TOOLTxD) pins. It supports breakpoints, watchpoints, and real-time variable monitoring using Renesas CS+ or e² studio - no external debugger required for basic firmware development and validation.
How many analog input channels does the R5F104BAGNA#20 support?
The R5F104BAGNA#20 supports up to 20 analog input channels (ANI0–ANI19) with 10-bit resolution. Channels ANI0–ANI3 are mapped to P20–P23; ANI16–ANI19 appear on P00, P01, P120, and P147. All channels operate across the full 1.6–5.5 V supply range and support internal 1.45 V reference or external references.
Can the R5F104BAGNA#20 perform data flash writes while executing application code?
Yes, the R5F104BAGNA#20 supports background operation (BGO) for data flash. Instructions can be fetched and executed from code flash while data flash is being rewritten - enabled via the FLMCR register. This allows uninterrupted real-time operation during firmware parameter updates or data logging.
What oscillator options are available on the R5F104BAGNA#20?
The R5F104BAGNA#20 integrates a high-accuracy on-chip oscillator (1–64 MHz, ±1.0% over −40 to +105°C) and a low-speed subsystem clock (32.768 kHz). External crystals (X1/X2) or resonators (XT1/XT2) may be used for higher precision timing, but are optional - the on-chip oscillator suffices for most industrial control applications.
