Overview

R7F101G7G2DNP#AA1 from Renesas is a 24-pin HWQFN-packaged RL78/G24 16-bit microcontroller featuring 128 KB code flash, 12 KB RAM, and 4 KB data flash, operating at up to 48 MHz with 50 µA/MHz ultra-low-power efficiency. It integrates FAA accelerator, dual DACs, 4-channel comparator, 23-channel 12-bit ADC, DALI-2 interface, and KB30–KB32 complementary PWM timers for digital power supply and lighting control.

For engineers reviewing the R7F101G7G2DNP#AA1 datasheet, R7F101G7G2DNP#AA1 pinout, R7F101G7G2DNP#AA1 application, or R7F101G7G2DNP#AA1 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm) footprint, –40 to +85°C consumer-grade temperature range, DALI-2 compliance, and integrated flexible application accelerator for real-time motor and lighting control loops.

Technical Context

The R7F101G7G2DNP#AA1 implements a CISC-based RL78 CPU core with 3-stage pipeline and configurable instruction timing (0.02083 µs min at 48 MHz), paired with a dedicated Flexible Application Accelerator (FAA) supporting 32-bit signed multiply/accumulate and limit operations. Its timer subsystem includes TAU (4-channel), RD2 (2-channel PWMOPA), RG2, RX, and three 16-bit KB-series timers optimized for PFC and multi-phase power control.

Peripheral integration centers on mixed-signal capability: 23-channel 12-bit ADC with dual sample-and-hold, dual 8-/10-bit DACs (0–VDD output), four comparators with selectable reference sources, and dedicated DALI-2 physical layer support - all coordinated via Event Link Controller (ELC) for deterministic low-latency peripheral triggering without CPU intervention.

FAQ

What is the maximum operating frequency and associated current consumption of the R7F101G7G2DNP#AA1?

The R7F101G7G2DNP#AA1 operates at up to 48 MHz with a typical active current of 50 µA/MHz, resulting in ~2.4 mA total at full speed. This ultra-low-power efficiency is achieved through Renesas' proprietary low-leakage process and dynamic voltage scaling, enabling extended runtime in battery-backed lighting controllers while maintaining real-time responsiveness.

Does the R7F101G7G2DNP#AA1 include an integrated DALI-2 physical layer?

Yes, the R7F101G7G2DNP#AA1 integrates a fully compliant DALI-2 physical layer per IEC 62386-102, including differential driver/receiver circuitry, current-limiting, and fault detection-eliminating the need for external transceivers. This integration reduces BOM cost, improves EMC robustness, and simplifies layout for certified digital lighting systems.

How many analog-to-digital converter channels does the R7F101G7G2DNP#AA1 support, and what is their resolution?

The R7F101G7G2DNP#AA1 supports up to 23 analog input channels with selectable 8-/10-/12-bit resolution. Two channels feature independent sample-and-hold circuits, enabling true simultaneous sampling-critical for vector-controlled motor drives and multi-phase power supply monitoring where timing skew between measurements must be eliminated.

What packaging and temperature grade does the R7F101G7G2DNP#AA1 use?

The R7F101G7G2DNP#AA1 uses a 24-pin HWQFN package (4 × 4 mm, 0.50-mm pitch) with exposed die pad and is rated for –40°C to +85°C ambient operation (consumer-grade, "D" suffix). This compact, thermally efficient package suits space-constrained lighting modules and indoor power electronics where extended industrial temperature range is not required.

Can the R7F101G7G2DNP#AA1 perform background data flash rewriting while executing code from main flash memory?

Yes, the R7F101G7G2DNP#AA1 supports Background Operation (BGO) for data flash, allowing firmware or calibration parameters to be rewritten while the CPU continues executing from program memory. This capability is essential for field-upgradable DALI devices that require seamless firmware updates without service interruption or system reset.
