Product details
Overview
R7F101GBG2DFP#AA1 from Renesas is a 32-pin LQFP-packaged RL78/G24 16-bit microcontroller featuring 128 KB code flash, 4 KB data flash, and 12 KB RAM, operating at up to 48 MHz with 50 µA/MHz ultra-low-power consumption. It integrates FAA for motor control acceleration, dual DACs (8-/10-bit), 12-bit ADC with 23 channels, four comparators, and DALI-2 interface - deployed in digital power supplies and LED lighting controllers.
For engineers reviewing the R7F101GBG2DFP#AA1 datasheet, R7F101GBG2DFP#AA1 pinout, R7F101GBG2DFP#AA1 application, or R7F101GBG2DFP#AA1 equivalent, key selection criteria include its 32-pin LQFP-0.80mm package, –40°C to +85°C industrial temperature grade, integrated DALI-2 transceiver support, and FAA-accelerated PFC timing resolution of 651 ps.
Technical Context
The R7F101GBG2DFP#AA1 implements a CISC-based RL78 CPU core with 3-stage pipeline and flexible clocking (1–64 MHz on-chip oscillators ±1.0% accuracy), enabling high-speed wakeup from STOP mode and SNOOZE-mode background operation. Its FAA core provides dedicated 32-bit signed arithmetic, limit operations, and 32-byte shared memory with the main CPU for real-time motor control loops.
Peripheral integration includes six I²C/Simplified I²C interfaces, two UART/LIN channels, up to six simplified SPIs, one DALI interface, and timer subsystems comprising TAU (4-channel), RD2 (2-channel PWMOPA), RG2, RX, and KB30–KB32 complementary-output timers supporting interleaved PFC and dithering with 651-ps average resolution at 96 MHz.

FAQ
What is the maximum operating frequency and power efficiency of the R7F101GBG2DFP#AA1?
The R7F101GBG2DFP#AA1 operates at up to 48 MHz with an ultra-low active current of 50 µA/MHz. Its high-speed on-chip oscillator achieves ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C, eliminating need for external crystal in most DALI and lighting applications. This efficiency enables battery-backed operation in emergency lighting systems.
Does the R7F101GBG2DFP#AA1 support DALI-2 compliance out of the box?
Yes, the R7F101GBG2DFP#AA1 integrates a fully compliant DALI-2 physical layer-including programmable current sink/source, differential receiver, and protocol-timed output drivers-requiring no external transceiver. Its P00/P01 pins directly connect to DALI bus lines, and firmware libraries from Renesas provide certified DALI-2 stack implementation.
How does the Flexible Application Accelerator (FAA) improve motor control performance in the R7F101GBG2DFP#AA1?
The FAA in the R7F101GBG2DFP#AA1 accelerates 32-bit signed multiply-accumulate, limit, and bit-shift operations independently of the RL78 CPU. This offloads inner-loop FOC calculations-reducing PFC timing jitter to <1 µs-and frees CPU bandwidth for communication, diagnostics, and safety monitoring in BLDC and PMSM drives.
What are the key differences between R7F101GBG2DFP#AA1 and R7F101GBE2DFP#AA1?
The R7F101GBG2DFP#AA1 and R7F101GBE2DFP#AA1 share identical 32-pin LQFP-0.80mm packaging, pinout, peripherals, and timing specs-but differ in code flash capacity: 128 KB vs. 64 KB. All other features-including DALI-2 interface, FAA, KB timers, and ADC/DAC-are functionally identical, making them drop-in replacements where firmware size permits.
Can the R7F101GBG2DFP#AA1 perform background data flash rewriting while executing application code?
Yes, the R7F101GBG2DFP#AA1 supports Background Operation (BGO) for data flash. Code execution continues uninterrupted from program memory during data flash erase/write cycles-enabling safe, zero-latency firmware updates and parameter storage in live DALI lighting systems without disrupting illumination or communication.
