Product details
Overview
R7F101GGE4CFB#AA1 from Renesas is a 48-pin LFQFP-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 16-bit complementary PWM timers KB30–KB32 - deployed in digital power supplies and LED lighting systems.
For engineers reviewing the R7F101GGE4CFB#AA1 datasheet, R7F101GGE4CFB#AA1 pinout, R7F101GGE4CFB#AA1 application, or R7F101GGE4CFB#AA1 equivalent, key selection criteria include its −40°C to +125°C industrial temperature grade, 48-pin LFQFP (0.50-mm pitch) package, DALI-2 compliance, and integrated 651-ps resolution PWM timing for PFC and multi-phase lighting drivers.
Technical Context
The R7F101GGE4CFB#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 33-bit internal precision and shared 32-byte memory with the CPU.
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 six I²C/SMBus interfaces - one configured as PMBus and another as DALI-2 physical layer, enabling direct interoperability with IEC 62386-compliant lighting control networks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F101GGG4CFB#AA1 | Same package and pinout; differs only in code flash configuration (128 KB vs. 128 KB) - no functional difference | Identical use cases; no design change required | Select when identical functionality with standard flash layout is preferred over E-model variants |
| R7F101GGE3CFB#AA1 | Same silicon; rated for −40°C to +105°C (3C) instead of +125°C (4C); otherwise identical peripherals and memory | Suitable for industrial environments below 105°C; not qualified for under-hood or high-temp LED driver enclosures | Choose for cost-sensitive designs where extended temperature range is unnecessary |
Compared with R7F101GGE4CFB#AA1, R7F101GGG4CFB#AA1 offers identical performance and qualification but uses default flash organization, while R7F101GGE3CFB#AA1 trades 20°C thermal margin for lower unit cost - both retain full DALI-2, FAA, and 651-ps PWM capability.

Does the R7F101GGE4CFB#AA1 include hardware support for DALI-2 communication?
Yes, the R7F101GGE4CFB#AA1 integrates a complete DALI-2 physical layer compliant with IEC 62386-102, including bus voltage regulation, short-circuit protection, and signal shaping circuitry on pins P00 (DALITxD0) and P01 (DALIRxD0). No external transceiver is required for DALI-2 master or slave operation.
How many analog-to-digital converter channels does the R7F101GGE4CFB#AA1 support, and what is their resolution?
The R7F101GGE4CFB#AA1 features two independent 12-bit SAR ADCs supporting up to 23 analog input channels total. Two channels (ANI0/ANI1) connect to separate sample-and-hold circuits, enabling true simultaneous sampling - essential for voltage/current vector acquisition in digital power and motor control.
What is the PWM timing resolution achievable with the R7F101GGE4CFB#AA1's KB30–KB32 timers?
The R7F101GGE4CFB#AA1's KB30, KB31, and KB32 16-bit complementary timers deliver 651-ps average output resolution when operating at 96 MHz with dithering enabled. This enables precise phase-shifted dimming in LED drivers and accurate dead-time control in PFC stages without external timing ICs.
Is the R7F101GGE4CFB#AA1 pin-compatible with other RL78/G24 variants in the 48-pin LFQFP package?
Yes, all RL78/G24 48-pin LFQFP variants - including R7F101GGE4CFB#AA1, R7F101GGG4CFB#AA1, and R7F101GGE3CFB#AA1 - share identical pinout, package dimensions (7 mm × 7 mm, 0.50-mm pitch), and thermal pad layout.
