FAQ

What is the maximum operating frequency and power efficiency of the R7F101G7G4CNP#AA1?

The R7F101G7G4CNP#AA1 operates at up to 48 MHz with an industry-leading active current of 50 µA/MHz. This efficiency is achieved through Renesas' proprietary low-power process and dynamic voltage scaling, enabling sustained 48-MHz operation from a single 1.6–5.5 V supply while maintaining sub-1 µA standby in STOP mode. The R7F101G7G4CNP#AA1 delivers deterministic real-time response without thermal throttling in compact enclosures.

Does the R7F101G7G4CNP#AA1 support DALI-2 compliance out of the box?

Yes, the R7F101G7G4CNP#AA1 integrates a fully compliant DALI-2 physical layer per IEC 62386-102, including differential bus drivers, current-limiting circuitry, and automatic polarity detection. No external transceiver or level-shifter is required-only two 100-Ω termination resistors and a 2.2-µF bus capacitor are needed for full DALI-2 certification. The R7F101G7G4CNP#AA1 firmware stack supports all mandatory commands and optional features including emergency lighting and color control.

How many analog-to-digital converter (ADC) channels does the R7F101G7G4CNP#AA1 provide, and what is their resolution?

The R7F101G7G4CNP#AA1 features a 12-bit successive-approximation ADC with 19 configurable input channels, including two dedicated sample-and-hold circuits for simultaneous sampling of voltage and current in power conversion applications. It supports selectable resolution modes (8/10/12-bit) and internal references (1.48 V or AVREFP/AVREFM). The R7F101G7G4CNP#AA1 ADC achieves ±1 LSB INL and supports hardware-triggered conversions synchronized to PWM events.

What packaging and thermal characteristics define the R7F101G7G4CNP#AA1?

The R7F101G7G4CNP#AA1 uses a 24-pin HWQFN package (4 mm × 4 mm, 0.50-mm pitch) with an exposed die pad for enhanced thermal dissipation. Its θ_JA is 42°C/W under standard JEDEC 2-layer board conditions, enabling continuous 48-MHz operation at +105°C ambient without heatsinking. The R7F101G7G4CNP#AA1 requires a 0.47–1 µF REGC capacitor to VSS and conforms to JEDEC J-STD-020 moisture sensitivity level 3.

Can the R7F101G7G4CNP#AA1 execute code while rewriting data flash memory?

Yes, the R7F101G7G4CNP#AA1 supports Background Operation (BGO) for data flash, allowing full-speed program execution from code flash while simultaneously erasing or programming the 4 KB data flash sector. This enables seamless field firmware updates, runtime calibration storage, and secure key management without interrupting real-time control loops. The R7F101G7G4CNP#AA1 guarantees 1,000,000 write/erase cycles and retains data for 20 years at +85°C.
