FAQ

What is the maximum operating frequency and corresponding performance of the R5F100AFGSP#30?

The R5F100AFGSP#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This speed is achievable across the full 1.6–5.5 V supply range and -40°C to +105°C temperature range, making R5F100AFGSP#30 suitable for deterministic real-time control in industrial environments without thermal derating.

Does the R5F100AFGSP#30 support LIN communication, and how is it implemented?

Yes, the R5F100AFGSP#30 supports LIN communication through its UART peripheral, which includes dedicated LIN-break detection and sync field generation hardware. This enables R5F100AFGSP#30 to serve as a LIN slave node without external transceivers or software bit-banging - reducing BOM cost and improving protocol compliance in automotive body electronics and industrial networks.

What are the data flash capabilities of the R5F100AFGSP#30, and how does background operation benefit firmware design?

The R5F100AFGSP#30 includes 4 KB of data flash with background operation (BGO), allowing CPU instructions to execute from program memory while data flash is being rewritten. This enables R5F100AFGSP#30 to log sensor data or store calibration parameters without interrupting real-time control loops - critical for applications like predictive maintenance where continuous operation is mandatory.

How does the R5F100AFGSP#30 handle power supply supervision and brown-out conditions?

The R5F100AFGSP#30 integrates an on-chip voltage detector (LVD) with 14 selectable threshold levels (1.6 V to 4.2 V), configurable to generate either interrupts or resets. This eliminates the need for external supervisor ICs and allows R5F100AFGSP#30 to implement graceful shutdown, non-volatile state saving, or safe actuator deactivation before supply collapse - enhancing system reliability in fluctuating industrial power environments.

Is the R5F100AFGSP#30 pin-compatible with other RL78/G13 variants in the same package, and what are the implications for design reuse?

Yes, the R5F100AFGSP#30 is pin-compatible with all other 30-pin LSSOP RL78/G13 variants (e.g., R5F100AGGSP#30, R5F101AFGSP#30), sharing identical pin functions and electrical characteristics. This enables R5F100AFGSP#30 to serve as a baseline design choice, with memory and feature scalability achieved through firmware and BOM updates - reducing NRE costs and accelerating time-to-market for derivative products.
