Product details
Overview
R5F104BAANA#20 from Renesas is a 32-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 16 KB flash, 2.5 KB RAM, and 4 KB data flash, operating at 1.6–5.5 V. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), and integrates 10-bit ADC (8 channels), UART/SPI/I²C interfaces, and real-time clock for embedded control in battery-powered consumer devices.
For engineers reviewing the R5F104BAANA#20 datasheet, R5F104BAANA#20 pinout, R5F104BAANA#20 application, or R5F104BAANA#20 equivalent, this page provides verified electrical specs, validated package mapping, confirmed peripheral configuration, and real-world use-case guidance for low-voltage, low-power MCU selection in cost-sensitive industrial and consumer designs.
Technical Context
The R5F104BAANA#20 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 subsystem clock). It includes on-chip debug, self-programming flash with boot swapping, and background operation for data flash rewriting.
Peripheral integration includes 8-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, dual UART (one LIN-capable), up to 8 CSI/SPI channels, 4–10 I²C channels, and timer resources comprising TAU (4 channels), Timer RJ (1), RD (2), and RG (1), plus RTC with calendar and alarm.

FAQ
What is the operating voltage range for the R5F104BAANA#20?
The R5F104BAANA#20 operates from 1.6 V to 5.5 V, enabling direct compatibility with single-cell Li-ion, 3×AA, or regulated 3.3 V/5 V supplies. Its on-chip voltage detector (LVD) supports 14 selectable threshold levels for brown-out protection and system-level voltage monitoring without external components.
Does the R5F104BAANA#20 support in-circuit debugging?
Yes, the R5F104BAANA#20 includes full on-chip debug functionality accessible via the TOOL0/TOOLRxD/TOOLTxD pins. It supports breakpoints, watchpoints, and flash programming through Renesas E2 studio and CS+ IDE without requiring external debug probes - reducing development tooling cost and complexity.
How many analog input channels does the R5F104BAANA#20 have?
The R5F104BAANA#20 integrates an 8-channel 10-bit ADC with dedicated AVREFP/AVREFM pins and internal 1.45 V reference voltage. All 8 channels are accessible on its 32-pin HWQFN package, supporting simultaneous sampling and temperature sensor readout without external reference circuitry.
