This specification is guaranteed for G-grade operation and eliminates the need for an external crystal in many applications, reducing BOM cost and PCB area. The oscillator supports eight selectable frequencies (1–24 MHz) and can be used directly as the system clock source.
Does R5F10269GSP#35 support background data flash rewriting during program execution?
Yes, the R5F10269GSP#35 supports Background Operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors - essential for seamless firmware updates, parameter logging, or configuration storage without interrupting real-time control tasks. The BGO function is hardware-managed and requires no software polling.
What safety features are implemented in R5F10269GSP#35 for industrial applications?
The R5F10269GSP#35 includes hardware CRC calculation unit, RAM guard, and SFR guard - all part of Renesas' functional safety support for IEC 61508 SIL2-ready designs. These features detect memory corruption and unauthorized register access, enabling robust error detection in safety-critical industrial control loops. No additional external monitoring circuitry is required to meet basic diagnostic coverage targets.
How many analog input channels and what ADC resolution does R5F10269GSP#35 provide?
The R5F10269GSP#35 integrates a 10-bit successive-approximation ADC with 11 input channels (ANI0–ANI3, ANI16–ANI22), supporting single-ended and differential measurements. It includes an internal 1.45 V reference voltage and temperature sensor, allowing accurate analog sensing without external references. Conversion time is 1.2 μs per sample at maximum speed, enabling real-time sensor fusion in closed-loop systems.
Is R5F10269GSP#35 pin-compatible with other RL78/G12 20-pin variants?
Yes, the R5F10269GSP#35 uses the standard 20-pin TSSOP package (PTSP0020JI-A) and shares identical pinout with all R5F102xxGSP#35 and R5F102xxDSP#35 variants. Pin functions are consistent across memory configurations (e.g., R5F10268GSP#35, R5F10267GSP#35), enabling hardware reuse and firmware scalability through simple flash reprogramming - no PCB redesign is required when upgrading memory capacity.
