Renesas R5F104BAGFP#10

Overview

R5F104BAGFP#10 from Renesas is a 32-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 48-pin LFQFP (0.5 mm pitch) package, operating from 1.6–5.5 V at -40 to +105°C. 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 10-bit ADC (12 channels), UART/SPI/I²C interfaces, and real-time clock for industrial control applications.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F104BAGFP#10?

The R5F104BAGFP#10 operates up to 32 MHz, delivering 44 DMIPS of processing performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator. The device maintains this performance across its full 1.6–5.5 V supply range and −40 to +105°C temperature grade, making R5F104BAGFP#10 suitable for deterministic real-time control in industrial environments where timing consistency is critical.

Does the R5F104BAGFP#10 support in-system programming and secure firmware updates?

Yes, the R5F104BAGFP#10 supports self-programming of both code and data flash memory with boot swapping and flash shield window protection. Its 96 KB code flash includes block-erase prohibition and security lock features to prevent unauthorized readout or modification. These capabilities allow safe field firmware updates and secure bootloader implementation - essential for maintaining R5F104BAGFP#10-based devices throughout their operational lifetime.

How does the Event Link Controller (ELC) enhance real-time responsiveness in the R5F104BAGFP#10?

The ELC in the R5F104BAGFP#10 enables hardware-level linking of up to 26 peripheral events - such as timer overflows, ADC completions, or UART receptions - directly to target peripherals like PWM generators or DMA controllers. This eliminates CPU interrupt latency and software overhead, achieving sub-microsecond deterministic response. In R5F104BAGFP#10-based motor control, ELC synchronizes ADC sampling with PWM dead-time insertion without CPU involvement.

What are the power management modes supported by the R5F104BAGFP#10, and what are their typical current draws?

The R5F104BAGFP#10 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.60 μA (typical); in active mode at 32 MHz, it draws 66 μA/MHz. HALT mode reduces current further by stopping the CPU clock while preserving RAM and register contents. These modes are configurable via software and support rapid wake-up - critical for R5F104BAGFP#10 deployments in energy-constrained edge devices.

Is the R5F104BAGFP#10 pin-compatible with other RL78/G14 variants in the same package?

Yes, all RL78/G14 devices in the 48-pin LFQFP package - including R5F104BAGFP#10, R5F104BGAFP#10, and R5F104BEAFP#10 - share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint for memory scaling or cost optimization without PCB redesign. All variants maintain consistent peripheral mapping and I/O functionality, ensuring R5F104BAGFP#10 hardware compatibility across the G14 48-pin family.
