Product details
Overview
R7F101GLE2DFB#AA1 from Renesas is a 64-pin LFQFP-packaged RL78/G24 16-bit microcontroller with 64 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 KB30–KB32 complementary PWM timers - deployed in digital power supplies and LED lighting systems.
For engineers reviewing the R7F101GLE2DFB#AA1 datasheet, R7F101GLE2DFB#AA1 pinout, R7F101GLE2DFB#AA1 application, or R7F101GLE2DFB#AA1 equivalent, key selection criteria include its 64-pin LFQFP (0.50-mm pitch) package, –40°C to +85°C industrial temperature grade, integrated DALI-2 transceiver, and hardware-based flexible application accelerator for real-time PFC and multi-phase timing control.
Technical Context
The R7F101GLE2DFB#AA1 implements a CISC-based RL78 CPU core with 3-stage pipeline and variable instruction timing (0.02083 µs min @ 48 MHz), paired with a dedicated FAA coprocessor supporting 32-bit signed multiply/accumulate and limit operations. Its timer subsystem includes KB30–KB32 complementary PWM units with 651-ps average resolution (at 96 MHz dithering), enabling precise gate drive control for synchronous rectification and interleaved PFC.
It features dual 12-bit ADCs (23-channel total) with two independent sample-and-hold circuits for simultaneous voltage/current acquisition, plus a single 8-/10-bit DAC, four comparators with selectable reference sources, and programmable gain amplifier - all synchronized via the Event Link Controller (ELC) for deterministic analog signal chain operation in closed-loop motor and power control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F101GLG2DFB#AA1 | Same RL78/G24 family, but with 128 KB code flash and identical 64-pin LFQFP package | Required when firmware exceeds 64 KB or future-proofing for feature expansion is needed | Select R7F101GLG2DFB#AA1 only if additional flash capacity is confirmed necessary; pinout and peripheral mapping are identical |
| R7F100GLG2DFB#AA0 | RL78/G14 derivative: no FAA, no DALI-2, fewer ADC channels (12 vs. 23), same 64-pin LFQFP | Suitable for cost-sensitive non-DALI lighting or basic motor control without advanced timing requirements | Choose only if FAA, DALI-2, or simultaneous dual ADC are not required; software migration requires peripheral reconfiguration |
Compared with R7F101GLG2DFB#AA1, the R7F101GLE2DFB#AA1 trades flash capacity for lower unit cost and smaller memory footprint, while retaining full peripheral compatibility; versus R7F100GLG2DFB#AA0, it adds hardware-accelerated motor control, DALI-2, and enhanced analog resources - justifying its use in digitally regulated power and smart lighting.

FAQ
What is the maximum operating frequency and power consumption of the R7F101GLE2DFB#AA1?
The R7F101GLE2DFB#AA1 operates at up to 48 MHz with a typical active current of 50 µA/MHz at 3.3 V and 25°C. Its ultra-low-power design supports HALT mode (0.52 µA), STOP mode (0.23 µA), and SNOOZE mode - enabling battery-backed operation in lighting and appliance applications. The high-speed on-chip oscillator delivers ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C.
Does the R7F101GLE2DFB#AA1 support DALI-2 communication natively?
Yes, the R7F101GLE2DFB#AA1 includes a dedicated DALI-2 physical layer interface with built-in bus voltage monitoring, collision detection, and automatic timing recovery. It requires no external transceiver IC or level-shifting components, and supports both master and slave configurations per IEC 62386-102:2014. The DALI interface shares pins DALITxD0 and DALIRxD0 with standard GPIO functionality.
How many analog-to-digital converter channels does the R7F101GLE2DFB#AA1 have, and what is their resolution?
The R7F101GLE2DFB#AA1 features a 12-bit successive-approximation ADC with up to 23 analog input channels. Two of these channels (ANI0 and ANI1) are assigned to AVREFP and AVREFM for external reference voltage configuration. Critically, it includes two independent sample-and-hold circuits, enabling true simultaneous sampling of two signals - essential for current/voltage measurement in digital power converters.
What is the Flexible Application Accelerator (FAA) used for in the R7F101GLE2DFB#AA1?
The FAA in the R7F101GLE2DFB#AA1 is a dedicated coprocessor that offloads compute-intensive motor and power control tasks. It performs 32-bit signed multiply-accumulate, addition/subtraction with 33-bit internal precision, and configurable limit operations - accelerating PFC current loops, BLDC commutation, and PID calculations. FAA operates independently of the RL78 CPU and shares a 32-byte memory region for low-latency data exchange.
Is the R7F101GLE2DFB#AA1 pin-compatible with other RL78/G24 variants in the 64-pin LFQFP package?
Yes, all RL78/G24 devices in the 64-pin LFQFP package - including R7F101GLE2DFB#AA1, R7F101GLG2DFB#AA1, and R7F101GLE3CFB#AA1 - share identical pinouts and electrical characteristics. Differences are limited to flash size (64 KB vs. 128 KB), temperature grade (–40°C to +85°C vs. +105°C), and packaging specification (#AA1 tray vs. #HA1 tape). No PCB redesign is needed when migrating between these variants.
