FAQ
What is the maximum operating frequency and performance of the R5F101GFAFB#30?
The R5F101GFAFB#30 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and −40°C to +85°C. The R5F101GFAFB#30 maintains this performance while consuming only 66 μA per MHz, making it suitable for real-time control tasks in power-sensitive applications.
Does the R5F101GFAFB#30 include data flash memory?
No, the R5F101GFAFB#30 does not include data flash memory. As indicated by the "101" in its part number (per Renesas' naming convention), it provides 128 KB of code flash memory and 12 KB of RAM but omits dedicated data flash. For applications requiring non-volatile parameter storage, external EEPROM or emulated data flash in code flash must be implemented. The R5F100GFAFB#30 variant includes 8 KB of data flash.
What package type and pin pitch does the R5F101GFAFB#30 use?
The R5F101GFAFB#30 uses a 48-pin LFQFP package with 7 mm × 7 mm body size and 0.5 mm pin pitch. The "FB" suffix explicitly denotes the LFQFP-0.5mm variant, distinguishing it from the 0.8 mm pitch "FP" version. This fine-pitch package supports high-density PCB layouts while maintaining hand-solderability and standard reflow compatibility.
Is the R5F101GFAFB#30 qualified for industrial temperature operation?
Yes, the R5F101GFAFB#30 is rated for −40°C to +105°C operation, corresponding to the "G" grade in Renesas' part numbering. This qualification makes it suitable for under-hood automotive modules, factory automation controllers, and outdoor infrastructure equipment where extended thermal reliability is mandatory. The device integrates on-chip LVD and POR circuits optimized across this full range.
Which serial communication interfaces are supported by the R5F101GFAFB#30?
The R5F101GFAFB#30 supports three serial interface types: CSI (Renesas' SPI-compatible interface) with up to 8 channels, UART/LIN with up to 4 channels (including hardware LIN break detection), and I²C/Simplified I²C with up to 10 channels. These are implemented in shared pin resources - for example, P10 serves as SCK00 (CSI) and SCL00 (I²C), while P11 handles SI00 (CSI), RxD0 (UART), and SDA00 (I²C).
