For engineers reviewing the R7F101GLG3CFB#AA1 datasheet, R7F101GLG3CFB#AA1 pinout, R7F101GLG3CFB#AA1 application, or R7F101GLG3CFB#AA1 equivalent, key selection criteria include industrial-grade temperature range (–40°C to +105°C), 64-pin LFQFP-0.5 mm pitch package compatibility, DALI-2 compliance for smart lighting systems, and FAA core support for real-time motor control math operations.
Technical Context
The R7F101GLG3CFB#AA1 integrates an 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), plus a dedicated Flexible Application Accelerator (FAA) core for 32-bit signed multiply/accumulate and limit operations with 33-bit internal precision.

Does the R7F101GLG3CFB#AA1 include a dedicated DALI-2 interface?
Yes, the R7F101GLG3CFB#AA1 integrates a single dedicated DALI-2 physical layer interface compliant with IEC 62386-102. It supports full DALI-2 master functionality-including addressing, command execution, and status reporting-without requiring an external transceiver IC, reducing system BOM and board area.
What are the key differences between R7F101GLG3CFB#AA1 and R7F101GLE3CFB#AA1?
The R7F101GLG3CFB#AA1 and R7F101GLE3CFB#AA1 share identical package (64-pin LFQFP), pinout, peripherals, and temperature rating (–40°C to +105°C), but differ in flash capacity: R7F101GLG3CFB#AA1 has 128 KB code flash, while R7F101GLE3CFB#AA1 has 64 KB. All other specifications-including RAM, FAA, timers, and communication interfaces-are functionally identical.
Can the R7F101GLG3CFB#AA1 execute code while rewriting data flash memory?
Yes, the R7F101GLG3CFB#AA1 supports Background Operation (BGO) for its 4 KB data flash memory. This allows the RL78 CPU to execute instructions from code flash while simultaneously rewriting data flash-enabling seamless firmware updates, parameter storage, and logging without halting real-time control tasks.
What PWM resolution and features does the R7F101GLG3CFB#AA1 provide for motor control?
The R7F101GLG3CFB#AA1 includes three 16-bit complementary PWM timers (KB30, KB31, KB32) supporting up to six independent outputs with 651-ps average resolution when dithering is applied at 96 MHz.
