FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F104BFAFP#30?
The R5F104BFAFP#30 operates at up to 32 MHz with a measured performance of 44 DMIPS. This is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling efficient execution of real-time control algorithms and communication stacks without external acceleration.
Does the R5F104BFAFP#30 support hardware-accelerated data movement between peripherals and memory?
Yes, the R5F104BFAFP#30 includes a Data Transfer Controller (DTC) that supports normal, repeat, and block transfer modes triggered by 19–26 peripheral events. This enables zero-CPU-overhead transfers - for example, moving ADC conversion results directly into RAM or transmitting UART data without software polling or interrupts.
Can the R5F104BFAFP#30 perform flash self-programming while executing code from another memory region?
Yes, the R5F104BFAFP#30 supports boot swapping and flash shield window functionality, allowing safe in-application reprogramming of code flash. The flash library reserves dedicated RAM (start address FE900H) for self-programming operations, ensuring runtime code execution continues uninterrupted during firmware updates.
What are the key low-power modes supported by the R5F104BFAFP#30, and what is the typical current draw in each?
The R5F104BFAFP#30 supports HALT (66 μA/MHz), STOP (0.60 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, the device maintains real-time clock operation, voltage monitoring, and wake-up capability via 14-level LVD or external interrupts - making it suitable for decade-long battery deployments.
How many serial communication interfaces does the R5F104BFAFP#30 integrate, and are they independently configurable?
The R5F104BFAFP#30 integrates 4 UART/LIN channels, 10 I²C/simplified I²C channels, and 8 CSI (SPI-compatible) channels - all independently configurable via dedicated control registers and routed through the Event Link Controller (ELC). This allows concurrent, hardware-synchronized operation across multiple buses without resource conflict.
