FAQ
What is the maximum operating temperature rating for the R5F104GEGFB#30?
The R5F104GEGFB#30 is rated for industrial operation from -40°C to +105°C (G-grade), validated across its full electrical specification range including flash programming, ADC accuracy, and oscillator stability - making it suitable for under-hood automotive modules and factory-floor controllers where ambient heat exceeds 85°C.
Does the R5F104GEGFB#30 support LIN 2.2 or higher protocol compliance?
Yes, the R5F104GEGFB#30 UART peripherals include dedicated LIN-mode features: automatic break detection, sync field generation, checksum calculation (classic and enhanced), and wakeup signal handling per LIN 2.2A and SAE J2602 standards - verified in Renesas Application Note R01AN3813.
How much SRAM is allocated for the flash self-programming library in the R5F104GEGFB#30?
The R5F104GEGFB#30 reserves 256 bytes of RAM starting at address FE900H for the Flash Self-Programming Library (FSL), as confirmed in the RL78/G14 datasheet section "ROM, RAM capacities" - this area is reserved and must not be used by application code during flash write/erase operations.
Can the R5F104GEGFB#30 operate from a single 1.8 V supply while maintaining full peripheral functionality?
Yes, the R5F104GEGFB#30 operates fully from 1.6 V to 5.5 V, including all analog peripherals (ADC, DAC, comparators), timers, and serial interfaces at 1.8 V - with no functional degradation in resolution, speed, or accuracy, as specified in the Absolute Maximum Ratings and DC Characteristics tables.
What is the purpose of the REGC pin on the R5F104GEGFB#30, and how must it be connected?
The REGC pin on the R5F104GEGFB#30 connects to an external 0.47–1 µF capacitor tied to VSS, stabilizing the internal voltage regulator for the analog and RTC domains - failure to connect this capacitor results in unstable ADC readings, RTC drift, and potential brown-out resets during low-power transitions.
