FAQ
What is the maximum operating frequency and core architecture of the R7F101GGE2DFB#AA1?
The R7F101GGE2DFB#AA1 features a 16-bit RL78 CPU core with CISC architecture and 3-stage pipeline, operating at up to 48 MHz. Its minimum instruction execution time is 0.02083 µs at full speed using the high-speed on-chip oscillator or PLL clock, and extends to 30.5 µs at 32.768 kHz for ultra-low-power operation.
Does the R7F101GGE2DFB#AA1 support DALI-2 communication natively?
Yes, the R7F101GGE2DFB#AA1 includes a dedicated digital addressable lighting interface (DALI) peripheral that implements DALI-2 physical layer and protocol timing requirements per IEC 62386-102. It uses P00 (DALITxD0) and P01 (DALIRxD0) pins with internal current-limiting and slew-rate control, eliminating need for external transceivers.
What are the memory resources available on the R7F101GGE2DFB#AA1?
The R7F101GGE2DFB#AA1 provides 128 KB of code flash memory (2 KB block size, security lockable), 4 KB of data flash memory supporting background rewriting and 1,000,000 write cycles (typ.), and 12 KB of on-chip RAM including 32 bytes of shared memory accessible by both the RL78 CPU and FAA core.
How does the Flexible Application Accelerator (FAA) enhance real-time control in the R7F101GGE2DFB#AA1?
The FAA core in the R7F101GGE2DFB#AA1 accelerates 32-bit signed arithmetic operations - including multiply, accumulate, add, subtract, and limit functions - with 33-bit internal precision. This offloads computationally intensive tasks like PID loop calculations or lighting color mixing from the main CPU, reducing interrupt latency and improving determinism in time-critical applications.
What PWM resolution and features are supported by the KB3x timers in the R7F101GGE2DFB#AA1?
The R7F101GGE2DFB#AA1 includes three 16-bit complementary PWM timers (KB30, KB31, KB32), each providing two outputs (up to six total). With dithering enabled at 96 MHz base clock, they achieve 651-ps average resolution - critical for high-fidelity current control in LED drivers and precise timing in digital PFC stages - and support forced output stop, smooth start, and multi-phase operation.
