Product details
Overview
R7F101GBG2DNP#AA1 from Renesas is a 32-pin HWQFN-packaged RL78/G24 16-bit microcontroller with 128 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 KB30–KB32 complementary PWM timers-targeting digital power supplies and lighting systems.
For engineers reviewing the R7F101GBG2DNP#AA1 datasheet, R7F101GBG2DNP#AA1 pinout, R7F101GBG2DNP#AA1 application, or R7F101GBG2DNP#AA1 equivalent, key selection criteria include its HWQFN-32 (5 × 5 mm, 0.50-mm pitch) package, –40 to +85°C consumer-grade temperature range, integrated DALI-2 transceiver, and 16-bit KB-series timers with 651-ps average resolution for PFC control.
Technical Context
The R7F101GBG2DNP#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 main CPU for real-time motor control loops.
Peripheral integration includes two 12-bit ADCs (23-channel total, two with independent sample-and-hold), 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-enabling precise timing-critical power conversion.

The R7F101GBG2DNP#AA1 supports a maximum CPU operating frequency of 48 MHz using the high-speed on-chip oscillator or PLL clock. At this speed, the minimum instruction execution time is 0.02083 µs. The device also supports ultra-low-speed operation at 32.768 kHz (30.5 µs per instruction) for real-time clock and low-power monitoring tasks-both modes are fully supported within the same R7F101GBG2DNP#AA1 silicon.
Does the R7F101GBG2DNP#AA1 include a built-in DALI-2 interface?
Yes, the R7F101GBG2DNP#AA1 integrates a dedicated digital addressable lighting interface (DALI) compliant with IEC 62386-102 (DALI-2). It provides both DALITxD0 and DALIRxD0 pins for direct connection to the DALI bus without external transceivers. This capability is confirmed in the RL78/G24 datasheet Section 1.1 Features and Table 1-2 through Table 1-6 for 32-pin HWQFN variants-including the R7F101GBG2DNP#AA1.
What are the key differences between R7F101GBG2DNP#AA1 and R7F101GBE2DNP#AA1?
The R7F101GBG2DNP#AA1 and R7F101GBE2DNP#AA1 share identical package (HWQFN-32), pinout, temperature grade (–40°C to +85°C), and peripheral set-including FAA, DALI-2, KB timers, and ADCs. Their sole difference is code flash capacity: R7F101GBG2DNP#AA1 has 128 KB, while R7F101GBE2DNP#AA1 has 64 KB. All other electrical, timing, and functional specifications are identical for the R7F101GBG2DNP#AA1 and R7F101GBE2DNP#AA1.
Can the R7F101GBG2DNP#AA1 operate from a 1.8-V supply?
Yes, the R7F101GBG2DNP#AA1 supports a wide operating voltage range of 1.6 V to 5.5 V, explicitly including 1.8 V. This is specified in Section 1.1 Features ("VDD = single power supply voltage of 1.6 to 5.5 V") and validated across all operating modes (HALT, STOP, SNOOZE, and active). At 1.8 V, the device maintains full functionality-including 48-MHz operation, ADC conversions, and DALI-2 communication-as confirmed in the RL78/G24 electrical characteristics tables.
How many analog input channels does the R7F101GBG2DNP#AA1 support?
The R7F101GBG2DNP#AA1 supports up to 23 analog input channels for its 12-bit ADC subsystem. Of these, two channels (ANI0 and ANI1, mapped to P20/P21) are each connected to independent sample-and-hold circuits-enabling true simultaneous sampling for voltage/current measurement in motor control or power supply applications. This configuration is fixed for the R7F101GBG2DNP#AA1 and documented in Section 1.1 "A/D converter" of the datasheet.
