Product details
Overview
R7F101GJG3CFA#AA1 from Renesas is a 52-pin LQFP-0.65mm MCU in the RL78/G24 family, featuring a 48-MHz RL78 CPU core, 128 KB code flash, 4 KB data flash, and 12 KB RAM. 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 controllers.
For engineers reviewing the R7F101GJG3CFA#AA1 datasheet, R7F101GJG3CFA#AA1 pinout, R7F101GJG3CFA#AA1 application, or R7F101GJG3CFA#AA1 equivalent, key selection criteria include its –40 to +105°C industrial temperature grade, 52-pin LQFP package with 0.65-mm pitch, DALI-2 compliance, and integrated PFC-capable KB-series timers supporting 651-ps average PWM resolution.
Technical Context
The R7F101GJG3CFA#AA1 implements a CISC-based RL78 CPU core with 3-stage pipeline and configurable instruction timing (0.02083 µs min at 48 MHz). Its Flexible Application Accelerator (FAA) provides dedicated 32-bit signed multiply/accumulate 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 S&H), four comparators with selectable D/A or external reference, and six I²C/SMBus interfaces - one configured as PMBus-compliant SM/PM bus and another as DALI-2 transceiver, enabling direct interoperability with lighting control systems per IEC 62386-102.
Key Specifications

| Operating Temp | –40 to +105°C (industrial grade, '3C' suffix); validated for continuous operation in enclosed LED drivers and power supply enclosures |
Pinout & Package
Package: 52-pin LQFP, 10 × 10 mm body, 0.65-mm lead pitch, exposed pad not present (per PLQP0052JA-A mechanical drawing).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / VSS | Power supply rails | Dual 1.6–5.5 V operation; separate analog/digital ground pins reduce noise coupling in mixed-signal motor control |

FAQ
What is the maximum operating frequency and associated current consumption of the R7F101GJG3CFA#AA1?
The R7F101GJG3CFA#AA1 operates at up to 48 MHz using its high-speed on-chip oscillator or PLL clock, achieving a typical operating current of 50 µA/MHz. At full 48-MHz operation, this translates to ~2.4 mA active current - verified under VDD = 3.3 V and TA = 25°C per R01DS0432EJ0120 Rev.1.20 Section 1.1.
Does the R7F101GJG3CFA#AA1 support DALI-2 communication out of the box?
Yes, the R7F101GJG3CFA#AA1 includes a dedicated DALI-2 transceiver compliant with IEC 62386-102. Pins P14 (DALIRxD0) and P15 (DALITxD0) implement the physical layer, and the on-chip peripheral handles protocol framing - no external transceiver or level shifter is required for standard DALI-2 node implementation.
How many analog input channels does the R7F101GJG3CFA#AA1 ADC support, and what is its sampling capability?
The R7F101GJG3CFA#AA1 features a 12-bit ADC with up to 23 analog input channels. Two of these channels (ANI0/ANI1 or configurable pairs) connect to independent sample-and-hold circuits, enabling true simultaneous sampling - essential for accurate three-phase current reconstruction in motor control applications.
What packaging and temperature grade does the R7F101GJG3CFA#AA1 use?
The R7F101GJG3CFA#AA1 is supplied in a 52-pin LQFP package (10 × 10 mm, 0.65-mm pitch, PLQP0052JA-A) and rated for industrial operation from –40 to +105°C ('3C' suffix). This grade ensures reliability in enclosed LED drivers and power supply environments where ambient temperatures exceed consumer-grade limits.
Can the R7F101GJG3CFA#AA1 execute motor control algorithms independently of the main CPU?
Yes - the R7F101GJG3CFA#AA1 integrates a Flexible Application Accelerator (FAA) core that runs 32-bit signed multiply-accumulate and limit operations in parallel with the RL78 CPU. The 32-byte shared memory allows coordinated real-time execution of field-oriented control loops without CPU intervention, reducing jitter and latency in closed-loop motor systems.
