Renesas R7F101G7E2DNP#AA1

Overview

R7F101G7E2DNP#AA1 from Renesas is a 24-pin HWQFN-packaged RL78/G24 16-bit microcontroller with 64 KB code flash, 4 KB data flash, and 12 KB RAM, operating at up to 48 MHz with 50-µA/MHz active current. It integrates FAA for motor control acceleration, dual DACs, 12-bit ADC with 12 channels, four comparators, and dedicated timers KB30–KB32 for PFC and PWM gating-targeting digital power supplies and lighting systems.

For engineers reviewing the R7F101G7E2DNP#AA1 datasheet, R7F101G7E2DNP#AA1 pinout, R7F101G7E2DNP#AA1 application, or R7F101G7E2DNP#AA1 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm) footprint, −40°C to +85°C consumer-grade temperature range, DALI-2 and PMBus/SMBus interface support, and integrated analog peripherals enabling compact, low-power motor and lighting control designs.

Technical Context

The R7F101G7E2DNP#AA1 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.02083 µs (48 MHz) to 30.5 µs (32.768 kHz). Its Flexible Application Accelerator (FAA) provides 32-bit signed multiply/accumulate with 33-bit internal precision and limit operations, directly offloading motor control math from the main CPU.

Peripheral integration includes two 8-/10-bit DACs (0 V to VDD output), a 12-bit ADC with 12 input channels and dual sample-and-hold, four independent comparators with selectable reference sources, and six 16-bit timers (TAU, RD2, RG2, RJ, KB30–KB32) supporting complementary PWM, dithering, and 651-ps average resolution in PFC mode at 96 MHz.

FAQ

What is the maximum operating frequency of the R7F101G7E2DNP#AA1?

The R7F101G7E2DNP#AA1 operates at a maximum CPU frequency of 48 MHz, achieved using the high-speed on-chip oscillator or PLL clock. At this speed, the minimum instruction execution time is 0.02083 µs, enabling deterministic real-time control for motor and power applications. The device also supports ultra-low-speed operation at 32.768 kHz (30.5 µs instruction time) for low-power timing functions.

Does the R7F101G7E2DNP#AA1 support DALI-2 communication natively?

Yes, the R7F101G7E2DNP#AA1 includes dedicated hardware support for DALI-2 communication via its UART0 peripheral (P00/TxD1 and P01/RxD1 pins), which implements the required half-duplex physical layer and framing. No external transceiver is needed, reducing BOM count and PCB area in lighting control designs.

How many analog-to-digital converter (ADC) channels does the R7F101G7E2DNP#AA1 have?

The R7F101G7E2DNP#AA1 features a 12-bit ADC with 12 analog input channels. Two of these channels (ANI30 and ANI29) are connected to separate sample-and-hold circuits, enabling simultaneous sampling for accurate phase current measurement in motor control applications.

What is the purpose of the Flexible Application Accelerator (FAA) in the R7F101G7E2DNP#AA1?

The FAA in the R7F101G7E2DNP#AA1 is a dedicated coprocessor that accelerates math-intensive control tasks-including 32-bit signed multiply, accumulate, add, subtract, and limit operations-with 33-bit internal precision. It offloads these computations from the main RL78 CPU, reducing loop latency and freeing CPU bandwidth for higher-layer tasks like communication and user interface.

What package type and pin count does the R7F101G7E2DNP#AA1 use?

The R7F101G7E2DNP#AA1 uses a 24-pin HWQFN package (4 × 4 mm, 0.50-mm pitch) with an exposed die pad. This compact, thermally efficient package is optimized for space-constrained applications such as LED drivers and smart lighting modules, and requires proper grounding of the exposed pad per Renesas layout guidelines.
