What low-power modes does the R5F101GHDFB#X0 support, and what is its lowest current consumption?
The R5F101GHDFB#X0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.57 μA - verified for industrial temperature range (−40°C to +105°C). This enables decade-scale battery operation in metering and remote sensing applications using the R5F101GHDFB#X0.
Is the R5F101GHDFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes - the R5F101GHDFB#X0 shares identical 48-pin LFQFP pinout and electrical characteristics with all other RL78/G13 devices in the FB package (e.g., R5F101GJDFB#X0, R5F101GLDFB#X0), including consistent peripheral mapping and power/ground pin locations. This enables drop-in memory upgrades without layout changes for the R5F101GHDFB#X0.
