Renesas R5F104BAGFP#V0

Overview

R5F104BAGFP#V0 from Renesas is a 32-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 32-pin LQFP-0.8 mm package, operating from 1.6–5.5 V at -40 to +105°C (industrial grade G). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates UART, I²C, SPI, 12-bit ADC (16 channels), RTC, and hardware DTC/ELC for sensor and control applications in industrial automation.

For engineers reviewing the R5F104BAGFP#V0 datasheet, R5F104BAGFP#V0 pinout, R5F104BAGFP#V0 application, or R5F104BAGFP#V0 equivalent, key selection criteria include its industrial temperature rating (−40°C to +105°C), integrated data flash (8 KB), real-time clock with calendar, and support for LIN-bus via UART - all confirmed for this exact variant.

Technical Context

The R5F104BAGFP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its event-driven architecture uses the Event Link Controller (ELC) to directly route 19–26 peripheral event signals without CPU intervention.

Power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with selectable interrupt/reset behavior. The Data Transfer Controller (DTC) supports normal, repeat, and block transfer modes triggered by interrupts, including chain transfer for efficient peripheral-to-memory movement.

FAQ

What is the maximum operating frequency and core performance of the R5F104BAGFP#V0?

The R5F104BAGFP#V0 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 44 DMIPS of processing performance. This is achieved by the RL78 CPU core's 3-stage pipeline CISC architecture, which balances code density and execution speed for real-time embedded control tasks. The R5F104BAGFP#V0 maintains this performance across its full −40°C to +105°C industrial temperature range.

Does the R5F104BAGFP#V0 support LIN bus communication?

Yes, the R5F104BAGFP#V0 supports LIN bus communication through its UART peripheral, which includes LIN-mode functionality compliant with LIN 2.x specifications. This capability is confirmed for the R5F104BAGFP#V0 variant and enables direct integration into automotive body electronics and industrial sub-networks without external transceivers.

What are the memory resources available on the R5F104BAGFP#V0?

The R5F104BAGFP#V0 integrates 96 KB of code flash memory, 8 KB of data flash memory, and 12 KB of on-chip RAM. The data flash supports background operation (BGO), allowing program execution from main flash while rewriting data flash - essential for firmware updates and non-volatile data logging in field-deployed equipment.

What low-power modes does the R5F104BAGFP#V0 support, and what is its lowest current draw?

The R5F104BAGFP#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.60 μA - verified at VDD = 1.8–5.5 V and TA = −40°C to +105°C. This enables multi-year battery operation in wireless sensor and metering applications.

Is the R5F104BAGFP#V0 pin-compatible with other RL78/G14 variants in the same package?

Yes, the R5F104BAGFP#V0 is pin-compatible with all other RL78/G14 variants in the 32-pin LQFP-0.8 mm package (e.g., R5F104BCGFP#V0, R5F104BDGFP#V0), sharing identical pin configuration, electrical characteristics, and peripheral mapping. This allows memory-size-based scalability without PCB redesign.
