Product details
Overview
R7F101GAG4CSP#AA1 from Renesas is a 30-pin LSSOP-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 DACs, 23-channel 12-bit ADC, four comparators, and DALI-2 interface - deployed in digital power supplies and lighting control systems.
For engineers reviewing the R7F101GAG4CSP#AA1 datasheet, R7F101GAG4CSP#AA1 pinout, R7F101GAG4CSP#AA1 application, or R7F101GAG4CSP#AA1 equivalent, key selection criteria include its 30-pin LSSOP package, –40°C to +125°C industrial temperature grade (4C), integrated DALI-2 transceiver, and FAA-assisted real-time PFC control capability.
Technical Context
The R7F101GAG4CSP#AA1 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution from 0.02083 µs (48 MHz) to 30.5 µs (32.768 kHz). Its Flexible Application Accelerator (FAA) provides dedicated 32-bit signed arithmetic, limit operations, and 32-byte shared memory with the CPU for deterministic motor timing loops.
Peripheral integration includes six I²C/Simplified I²C interfaces, two UART/LIN channels, one DALI-2 interface, three 16-bit timer KB units for complementary PWM generation, and a 32-bit interval timer with 651-ps average resolution when dithering is enabled at 96 MHz - all synchronized via Event Link Controller (ELC) for hardware-triggered event chaining without CPU intervention.

FAQ
What is the maximum operating frequency and power consumption of the R7F101GAG4CSP#AA1?
The R7F101GAG4CSP#AA1 operates at up to 48 MHz with a typical active current of 50 µA per MHz at 1.8–5.5 V supply. Its HALT, STOP, and SNOOZE modes reduce current to sub-µA levels, and high-speed wakeup from STOP mode is supported. These characteristics make the R7F101GAG4CSP#AA1 ideal for battery-backed lighting and portable industrial sensors requiring both performance and energy efficiency.
Does the R7F101GAG4CSP#AA1 support DALI-2 communication natively?
Yes, the R7F101GAG4CSP#AA1 includes a dedicated digital addressable lighting interface (DALI) peripheral that complies with DALI-2 standards. Pins P00 and P01 are configured as DALITxD0 and DALIRxD0, respectively, forming a complete DALI transceiver interface without external components. The R7F101GAG4CSP#AA1 also supports DALI timing-critical features such as 16-bit fade time and scene storage in data flash.
What analog peripherals are integrated into the R7F101GAG4CSP#AA1?
The R7F101GAG4CSP#AA1 integrates a 12-bit ADC with 23 input channels and dual sample-and-hold circuits, two 8-/10-bit DACs (VCOUT0/VCOUT1), four independent comparators (IVCMP0–IVCMP3), a programmable gain amplifier (PGAI0–PGAI4), and an internal temperature sensor. These analog resources are accessible through multiplexed pins like P14 (ANI24/VCOUT0/SCLA0) and P15 (ANI25/VCOUT1/SCK20), enabling compact mixed-signal designs in the R7F101GAG4CSP#AA1.
How does the Flexible Application Accelerator (FAA) enhance motor control on the R7F101GAG4CSP#AA1?
The FAA in the R7F101GAG4CSP#AA1 executes 32-bit signed multiply, add, subtract, and limit operations independently of the RL78 CPU, with 32-byte shared memory for data exchange. This offloads computationally intensive tasks like Clarke/Park transforms and PI control in FOC algorithms - reducing CPU load by up to 70% and enabling deterministic 20-kHz motor control loops. The R7F101GAG4CSP#AA1 leverages FAA to achieve real-time responsiveness unattainable with software-only execution.
What is the industrial temperature rating and package type of the R7F101GAG4CSP#AA1?
The R7F101GAG4CSP#AA1 is rated for –40°C to +125°C operation (4C grade) and housed in a 30-pin plastic LSSOP package with 0.65-mm pitch. This package meets JEDEC MS-012 standards, supports automated optical inspection, and is compatible with standard reflow profiles. The R7F101GAG4CSP#AA1's 4C rating ensures reliable operation in demanding environments such as outdoor LED drivers and industrial power converters.
