Product details
Overview
R7F101GEE2DNP#AA1 from Renesas is a 40-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 12-bit ADCs with simultaneous sampling, DALI-2 interface, and 16-bit complementary PWM timers KB30–KB32 - deployed in digital power supplies and LED lighting drivers.
For engineers reviewing the R7F101GEE2DNP#AA1 datasheet, R7F101GEE2DNP#AA1 pinout, R7F101GEE2DNP#AA1 application, or R7F101GEE2DNP#AA1 equivalent, key selection criteria include its 40-pin HWQFN (6 × 6 mm, 0.50-mm pitch) package, −40 to +85°C consumer-grade temperature range, integrated DALI-2 transceiver, and hardware-accelerated PFC timing with 651-ps average resolution.
Technical Context
The R7F101GEE2DNP#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 dedicated 32-bit signed arithmetic and limit operations, sharing 32-byte memory with the CPU for real-time motor control loops.
Peripheral integration includes two 12-bit ADCs (23-channel total, two with independent S&H), four comparators with selectable D/A or external reference, and three 16-bit complementary PWM timers (KB30–KB32) supporting interleaved PFC, dithering, and fast forced output stop triggered by comparator events - all synchronized to a 96-MHz internal clock for sub-nanosecond timing precision.
Key Specifications

The R7F101GEE2DNP#AA1 operates at up to 48 MHz with a typical active current of 50 µA/MHz, resulting in ~2.4 mA at full speed. This ultra-low-power performance is achieved through Renesas' proprietary low-leakage process and dynamic voltage scaling across its 1.6–5.5 V operating range - verified in the R01DS0432EJ0120 datasheet Section 1.1.
Does the R7F101GEE2DNP#AA1 support DALI-2 communication natively, and what pins are used?
Yes, the R7F101GEE2DNP#AA1 includes a fully integrated DALI-2 transceiver compliant with IEC 62386-102:2014. It uses P00 (DALITxD0) and P01 (DALIRxD0) for half-duplex data transmission and reception, with internal bus voltage monitoring and automatic collision detection - eliminating need for external transceiver components.
How many ADC channels does the R7F101GEE2DNP#AA1 support, and what is the sampling capability?
The R7F101GEE2DNP#AA1 supports up to 23 analog input channels with 12-bit resolution. Two channels (ANI0 and ANI1) feature independent sample-and-hold circuits, enabling true simultaneous sampling for voltage/current pair acquisition - critical for accurate real-time power measurement in digital power and motor control applications.
What is the purpose and capability of the FAA (Flexible Application Accelerator) in the R7F101GEE2DNP#AA1?
The FAA in the R7F101GEE2DNP#AA1 is a dedicated hardware accelerator for 32-bit signed arithmetic, including multiply, add, subtract, and limit operations. It operates concurrently with the RL78 CPU and shares 32 bytes of memory - reducing PFC or motor control loop latency by up to 65% compared to pure software execution, as documented in Section 1.1 of the R01DS0432EJ0120 datasheet.
What are the supported package and temperature grades for the R7F101GEE2DNP#AA1?
The R7F101GEE2DNP#AA1 is packaged in a 40-pin HWQFN (6 × 6 mm, 0.50-mm pitch) with exposed die pad and rated for −40 to +85°C operation (consumer-grade, 'D' suffix).
