The R5F10269ASP#35 operates at up to 24 MHz using its high-accuracy on-chip oscillator (±1.0% over –20°C to +85°C), delivering 31 DMIPS of processing performance. Its minimum instruction execution time is 0.04167 µs at 24 MHz, enabling responsive real-time control in motor drives and sensor fusion applications.
Does the R5F10269ASP#35 support background data flash rewriting while executing application code?
Yes, the R5F10269ASP#35 supports Background Operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute instructions from program memory while simultaneously erasing or writing to data flash - essential for seamless firmware updates and runtime parameter logging without interrupting control loops.
How many analog input channels and what ADC resolution does the R5F10269ASP#35 provide?
The R5F10269ASP#35 integrates an 8/10-bit resolution successive-approximation ADC with 11 analog input channels (ANI0–ANI3, ANI16–ANI22). It includes an internal 1.45 V reference voltage and a temperature sensor, enabling accurate voltage, current, and thermal measurements without external components.
What serial communication interfaces are available on the R5F10269ASP#35?
The R5F10269ASP#35 provides two simplified SPI (CSI) channels, two simplified I²C channels, and one UART channel - all accessible via shared pins and configurable through the Peripheral I/O Redirection Register (PIOR).
