FAQ
What is the maximum operating frequency and power consumption of the R5F104MHGFB#30?
The R5F104MHGFB#30 operates at up to 32 MHz (44 DMIPS) with an active current of 66 μA/MHz. In STOP mode with only RTC and LVD active, it draws just 0.60 μA - verified per R01DS0053EJ0370 Rev. 3.70, Section 1.1. This makes R5F104MHGFB#30 ideal for long-life battery applications where periodic wake-up and minimal leakage are critical.
Does the R5F104MHGFB#30 support in-system programming and secure firmware updates?
Yes, the R5F104MHGFB#30 supports full on-chip debug via single-wire interface and includes self-programming capabilities with boot swapping and flash shield window protection. These features enable secure field firmware updates without external programmers - confirmed in Section 1.1 "Code Flash Memory" of the R01DS0053EJ0370 datasheet. The R5F104MHGFB#30 implements hardware-level write protection to prevent unauthorized flash modification.
What analog peripherals are integrated into the R5F104MHGFB#30?
The R5F104MHGFB#30 integrates a 10-bit ADC with 16 input channels (ANI0–ANI16), internal 1.45 V reference voltage, on-die temperature sensor, two 8-bit D/A converters (0–VDD output), and up to two comparators. All analog functions operate across the full 1.6–5.5 V supply range - detailed in Sections 1.1 and 1.3.6 of R01DS0053EJ0370. This integration eliminates external signal-conditioning components for R5F104MHGFB#30-based designs.
Is the R5F104MHGFB#30 pin-compatible with other RL78/G14 variants in LFQFP-48 package?
Yes, all RL78/G14 devices in the LFQFP-48 package (e.g., R5F104MHGFB#30, R5F104LGFB#30, R5F104GGFB#30) share identical pinouts and electrical characteristics per R01DS0053EJ0370 Section 1.3.6. This allows direct substitution within the same footprint when memory or peripheral requirements change - provided software accommodates differences in flash size or feature enablement. The R5F104MHGFB#30 pin mapping is fully documented in Figure 1-12.
What industrial temperature and voltage specifications apply to the R5F104MHGFB#30?
The R5F104MHGFB#30 carries the 'G' suffix, specifying industrial-grade operation from –40°C to +105°C ambient temperature and 1.6–5.5 V supply voltage. It includes on-chip POR and 14-level LVD with interrupt/reset capability - validated per Section 1.1 "Power Management and Reset Function" and Table 1-1 of R01DS0053EJ0370. This makes R5F104MHGFB#30 suitable for harsh environments such as factory automation and outdoor metering.
