Product details
Overview
R7F101GAG2DSP#AA1 from Renesas is a 30-pin LSSOP-packaged RL78/G24 16-bit microcontroller with 128 KB code flash, 12 KB RAM, and 4 KB data flash, operating at up to 48 MHz. It integrates FAA for motor control acceleration, dual 12-bit ADCs with simultaneous sampling, DALI-2 interface, and operates from 1.6–5.5 V in consumer-grade –40°C to +85°C ambient.
For engineers reviewing the R7F101GAG2DSP#AA1 datasheet, R7F101GAG2DSP#AA1 pinout, R7F101GAG2DSP#AA1 application, or R7F101GAG2DSP#AA1 equivalent, key selection criteria include its 30-pin LSSOP package, integrated DALI-2 and PMBus/SMBus support, 12-bit ADC with dual sample-and-hold, FAA-based digital power supply control, and low-power STOP mode with fast wakeup.
Technical Context
The R7F101GAG2DSP#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 with limit operations and shared 32-byte memory between CPU and FAA.
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, three 16-bit KB timers for PFC and multi-phase motor control, and hardware DALI-2 transceiver compliant with IEC 62386-102.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F101GAG3CSP#AA1 | Same 30-pin LSSOP package but rated for –40°C to +105°C industrial operation (3C grade); identical peripherals and memory | Required for industrial lighting in high-ambient environments (e.g., enclosed streetlights, factory fixtures) | Select when extended temperature range is mandatory; otherwise R7F101GAG2DSP#AA1 suffices for indoor/commercial use |
| R7F101GBG2DNP#AA1 | 32-pin HWQFN package (5 × 5 mm), same 128 KB flash/12 KB RAM, but adds second DALI channel and extra UART | Enables dual-zone DALI control (e.g., tunable white + dimming) or DALI + UART diagnostics simultaneously | Choose when board space allows QFN and dual-interface capability is needed; LSSOP remains optimal for cost-sensitive, single-DALI designs |
Compared with R7F101GAG3CSP#AA1, the R7F101GAG2DSP#AA1 trades industrial temperature rating for lower unit cost and qualification scope; compared with R7F101GBG2DNP#AA1, it offers identical core functionality in a smaller-footprint LSSOP package but omits the second DALI interface and one UART channel.

FAQ
What is the maximum operating frequency and core architecture of the R7F101GAG2DSP#AA1?
The R7F101GAG2DSP#AA1 features a 16-bit RL78 CPU core with CISC architecture and 3-stage pipeline, operating at up to 48 MHz. At this speed, its minimum instruction execution time is 0.02083 µs using the high-speed on-chip oscillator or PLL clock. The core supports multiply/divide/accumulate instructions and a 1 Mbyte address space.
Does the R7F101GAG2DSP#AA1 include hardware support for DALI-2 communication?
Yes, the R7F101GAG2DSP#AA1 integrates a fully compliant DALI-2 transceiver per IEC 62386-102. Pins P00 (DALITxD0) and P01 (DALIRxD0) serve as dedicated DALI bus interface pins, eliminating the need for external transceiver ICs or level-shifting components in lighting control designs.
What ADC capabilities does the R7F101GAG2DSP#AA1 provide for power supply monitoring?
The R7F101GAG2DSP#AA1 includes a 12-bit ADC with up to 23 input channels, two of which feature independent sample-and-hold circuits for simultaneous sampling. This enables accurate concurrent measurement of input voltage and output current in digital power supplies-critical for real-time loop control and fault detection.
How does the Flexible Application Accelerator (FAA) in the R7F101GAG2DSP#AA1 improve motor or lighting control performance?
The FAA in the R7F101GAG2DSP#AA1 executes 32-bit signed arithmetic (multiply, add, subtract, limit) independently of the main CPU, with 32-byte shared memory. In lighting applications, it accelerates DALI command parsing and PWM parameter calculation; in digital power, it handles PFC correction loops-freeing the RL78 core for communications and supervision tasks.
What is the operating temperature range and package type of the R7F101GAG2DSP#AA1?
The R7F101GAG2DSP#AA1 is packaged in a 30-pin plastic LSSOP (7.62 mm, 0.65-mm pitch) and rated for consumer-grade operation from –40°C to +85°C (denoted by "2D" in the part number suffix). It requires a 0.47–1 µF capacitor between REGC and VSS for internal regulator stability.
