FAQ
What is the maximum operating frequency and voltage range supported by the R7F101GGG3CFB#AA1?
The R7F101GGG3CFB#AA1 operates at up to 48 MHz using its PLL or high-speed on-chip oscillator, with guaranteed accuracy of ±1.0% across 1.8–5.5 V supply and –40 to +105°C ambient. Its absolute operating voltage range is 1.6–5.5 V, enabling direct compatibility with Li-ion, 3.3 V, and 5 V system rails.
Does the R7F101GGG3CFB#AA1 include a built-in DALI-2 transceiver?
Yes, the R7F101GGG3CFB#AA1 integrates a complete DALI-2 physical layer interface - including differential driver/receiver circuitry - directly on-die. This eliminates the need for an external DALI transceiver IC and reduces bill-of-materials cost and PCB footprint in smart lighting applications.
How many analog-to-digital converter (ADC) channels does the R7F101GGG3CFB#AA1 support, and what is its resolution?
The R7F101GGG3CFB#AA1 features a 12-bit successive-approximation ADC with up to 23 configurable analog input channels. Two of these channels are connected to independent sample-and-hold circuits, enabling simultaneous sampling for accurate three-phase current measurement in motor control applications.
What low-power modes are available on the R7F101GGG3CFB#AA1, and what are their typical current draws?
The R7F101GGG3CFB#AA1 supports HALT (50 µA/MHz), STOP (0.23 µA typical), and SNOOZE modes. In STOP mode with RTC running, it consumes only 0.23 µA - making it suitable for battery-powered sensor nodes requiring multi-year operation on coin-cell batteries.
Is the R7F101GGG3CFB#AA1 pin-compatible with other RL78/G24 variants in the same package?
Yes, all RL78/G24 devices in the 48-pin LFQFP (FB) package - including R7F101GGG3CFB#AA1, R7F101GGE3CFB#AA1, and R7F101GGG4CFB - share identical pinouts and electrical characteristics. Firmware and hardware designs can be reused across flash-size variants without layout changes.
