Product details
Overview
R7F101GLE3CFB#AA1 from Renesas is a 64-pin LFQFP, 128 KB flash, 12 KB RAM RL78/G24 microcontroller with 48-MHz CPU, 50-µA/MHz ultra-low-power operation, integrated FAA accelerator, DALI-2 and PMBus/SMBus interfaces, and dual 12-bit ADCs for digital power supply and lighting control systems.
For engineers reviewing the R7F101GLE3CFB#AA1 datasheet, R7F101GLE3CFB#AA1 pinout, R7F101GLE3CFB#AA1 application, or R7F101GLE3CFB#AA1 equivalent, this device supports motor control timing with 651-ps PWM resolution, real-time D/A output for analog feedback loops, and hardware-accelerated PFC control - critical for industrial-grade LED drivers and AC-DC converters.
Technical Context
The R7F101GLE3CFB#AA1 implements a CISC-based RL78 CPU core with 3-stage pipeline and configurable instruction timing (0.02083 µs at 48 MHz or 30.5 µs at 32.768 kHz), paired with a dedicated Flexible Application Accelerator (FAA) core supporting 32-bit signed multiply/accumulate and limit operations with 33-bit internal precision.
It integrates dual 12-bit ADCs with simultaneous sampling on two channels, four comparators with selectable reference sources (including internal D/A outputs), and six 16-bit timers KB30–KB32 optimized for complementary PWM generation, dithering, and asynchronous forced stop - all synchronized via Event Link Controller (ELC) for deterministic timing in power electronics.

FAQ
What is the maximum operating frequency and power consumption of the R7F101GLE3CFB#AA1?
The R7F101GLE3CFB#AA1 operates at up to 48 MHz with a typical active current of 50 µA/MHz at 3.3 V and 25°C. Its HALT, STOP, and SNOOZE modes reduce current to sub-µA levels, and STOP-mode wakeup occurs in under 3.5 µs - making it ideal for battery-backed DALI commissioning tools and energy-sensitive lighting controllers where the R7F101GLE3CFB#AA1 balances performance and efficiency.
Does the R7F101GLE3CFB#AA1 include a built-in DALI-2 physical layer?
Yes, the R7F101GLE3CFB#AA1 integrates a fully compliant DALI-2 transceiver on die, supporting Class A timing (±100 ns) without external components. Pins P50 (DALIRxD0) and P51 (DALITxD0) provide direct connection to the DALI bus, and the firmware stack leverages the Event Link Controller (ELC) for deterministic interrupt response - a key capability confirmed in the R7F101GLE3CFB#AA1 datasheet section 1.2 and Figure 1-1.
What ADC and timer resources does the R7F101GLE3CFB#AA1 provide for motor or power control?
The R7F101GLE3CFB#AA1 features dual 12-bit ADCs with simultaneous sampling on two channels, four comparators with selectable references (including D/A outputs), and six 16-bit timers KB30–KB32. These KB timers deliver 651-ps average PWM resolution at 96 MHz with dithering, asynchronous forced stop, and PFC control modes - all coordinated via ELC. This makes the R7F101GLE3CFB#AA1 suitable for brushless DC motor commutation and digital power supply control where the R7F101GLE3CFB#AA1 replaces multiple discrete timing ICs.
Is the R7F101GLE3CFB#AA1 pin-compatible with other RL78/G24 variants in 64-pin packages?
The R7F101GLE3CFB#AA1 shares identical pinout and electrical characteristics with other 64-pin LFQFP RL78/G24 devices (e.g., R7F101GLG3CFB#AA1), including VDD/VSS placement, reset, crystal, and peripheral pin assignments. However, memory size differs: R7F101GLE3CFB#AA1 has 128 KB flash, while R7F101GGE3CFB#AA1 has 64 KB. Firmware must be validated for flash size, but PCB layout and signal routing remain unchanged for the R7F101GLE3CFB#AA1.
What development tools and software support are available for the R7F101GLE3CFB#AA1?
Renesas provides the e2 studio IDE with CS+ compiler support, FSP (Flexible Software Package) v4.x drivers for DALI-2, PMBus, ADC, and timer peripherals, and the RL78/G24 Target Board (YRDKRL78G24). The R7F101GLE3CFB#AA1 is supported in Renesas' official RA/RL78 Code Generator and complies with IEC 62386-102 for DALI-2 certification - enabling rapid prototyping of lighting and power applications using the R7F101GLE3CFB#AA1 without custom HAL development.
