Product details
Overview
R7F101GJE3CFA#AA1 from Renesas is a 52-pin LQFP-0.65mm, industrial-grade (−40 to +105°C) RL78/G24 microcontroller featuring a 48-MHz RL78 CPU core, 128 KB code flash, 4 KB data flash, and 12 KB RAM. It integrates FAA accelerator, 12-bit ADC (23 channels), dual DACs, four comparators, DALI-2 interface, and KB30–KB32 complementary PWM timers for digital power supply control.
For engineers reviewing the R7F101GJE3CFA#AA1 datasheet, R7F101GJE3CFA#AA1 pinout, R7F101GJE3CFA#AA1 application, or R7F101GJE3CFA#AA1 equivalent, key selection criteria include its 52-pin LQFP package with DALI-2 support, −40 to +105°C operation, integrated PFC-capable KB-series timers, and FAA-assisted motor/power control execution.
Technical Context
The R7F101GJE3CFA#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 CPU for real-time control loops.
Peripheral integration includes two 16-bit timer arrays (TAU), KB30–KB32 complementary PWM timers with 651-ps average resolution (at 96 MHz with dithering), DALI-2 physical layer interface, and PMBus/SMBus-compatible serial interfaces - all optimized for closed-loop digital power and lighting control systems requiring deterministic timing and low-latency analog feedback.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F101GJE3CFA#HA1 | Identical silicon; differs only in packaging (embossed tape vs. tray) | No functional difference; same electrical specs, timing, and peripheral set | Select #HA1 for automated SMT placement; #AA1 for manual prototyping or low-volume assembly |
| R7F101GJG3CFA#AA1 | Same package and pinout; 64 KB code flash (vs. 128 KB), no FAA core | Limited to simpler control tasks without hardware-accelerated math; insufficient for complex PFC or FOC | Choose only if application requires <64 KB code and no FAA-dependent algorithms; verify KB timer availability per variant |
Compared with R7F101GJE3CFA#AA1, the #HA1 variant offers identical functionality in tape-and-reel format for production lines, while the #GJG variant reduces flash and omits FAA - making it unsuitable for high-performance digital power or motor control where real-time computation offload is critical.

FAQ
What is the maximum operating frequency and power consumption of the R7F101GJE3CFA#AA1?
The R7F101GJE3CFA#AA1 operates at up to 48 MHz with a typical active current of 50 µA/MHz. In STOP mode, it draws just 0.23 µA, and HALT mode achieves 50 µA/MHz efficiency - enabling energy-sensitive applications such as battery-backed DALI lighting nodes. Its high-speed on-chip oscillator maintains ±1.0% accuracy from −20 to +85°C.
Does the R7F101GJE3CFA#AA1 support DALI-2 communication natively?
Yes, the R7F101GJE3CFA#AA1 integrates a full DALI-2 physical layer compliant with IEC 62386-102. Pins P00 and P01 serve as DALITxD0 and DALIRxD0, respectively, eliminating the need for external bus transceivers. The MCU supports both master and slave DALI-2 operation through firmware implementation of the protocol stack.
What are the key differences between the R7F101GJE3CFA#AA1 and R7F101GJG3CFA#AA1?
The R7F101GJE3CFA#AA1 features 128 KB code flash and the Flexible Application Accelerator (FAA) core, while the R7F101GJG3CFA#AA1 has only 64 KB flash and no FAA. Both share the same 52-pin LQFP package, 4 KB data flash, 12 KB RAM, and peripheral set - but FAA omission limits the #GJG variant's suitability for computationally intensive digital power or motor control algorithms.
Which PWM timers in the R7F101GJE3CFA#AA1 support complementary output and PFC control?
The R7F101GJE3CFA#AA1 includes three dedicated 16-bit complementary PWM timers - KB30, KB31, and KB32 - each providing two outputs (up to six total). These timers support single/interleaved PFC control, fixed-off time, dithering, and asynchronous forced stop triggered by comparators - essential for robust digital power supply design.
Is background data flash rewriting supported on the R7F101GJE3CFA#AA1?
Yes, the R7F101GJE3CFA#AA1 supports Background Operation (BGO) for its 4 KB data flash memory. This allows the CPU to execute instructions from program memory while simultaneously rewriting data flash - enabling seamless firmware updates, parameter storage, and calibration data persistence without halting real-time control tasks.
