FAQ
What is the maximum operating frequency of the R5F1211AGSP#30?
The R5F1211AGSP#30 supports a maximum operating frequency of 16 MHz using its on-chip high-speed oscillator. Instruction execution time can be as fast as 0.0625 μs under this condition. The oscillator offers selectable frequencies (16/8/4/2/1 MHz) with ±1.0% accuracy across −20°C to +85°C and VDD = 2.4–5.5 V. This eliminates the need for an external crystal in most applications while maintaining timing precision for real-time control tasks in the R5F1211AGSP#30.
Does the R5F1211AGSP#30 support in-system programming via its debug interface?
Yes, the R5F1211AGSP#30 supports full in-system programming and debugging through its TOOL0/TOOLRxD/TOOLTxD pins, which implement Renesas' on-chip debug interface. This enables flash programming, breakpoint setting, and real-time variable monitoring without removing the R5F1211AGSP#30 from the target board. The interface complies with Renesas' standard debug protocol and is compatible with E2 studio and CS+ IDEs for firmware development and field updates.
How many capacitive touch channels does the R5F1211AGSP#30 support, and what configurations are available?
The R5F1211AGSP#30 integrates a 15-channel capacitive touch sensing unit (CTSU) supporting both self-capacitance (up to 15 independent keys) and mutual-capacitance (up to 16 keys in matrix configuration) modes. All 15 channels are accessible via dedicated TSCAP and TSxx pins mapped to P02 and P03–P04. Configuration is performed through CTSU registers in firmware, with hardware-accelerated scanning and noise rejection-enabling robust touch performance in noisy industrial environments for the R5F1211AGSP#30.
What is the data retention endurance of the data flash memory in the R5F1211AGSP#30?
The data flash memory in the R5F1211AGSP#30 is rated for 1,000,000 write/erase cycles (typical) at VDD = 2.4–5.5 V. Each rewrite operates on 32-bit units, and erasure must precede writing. Background operation (BGO) is not supported-code execution halts from flash during data flash writes. This endurance specification ensures reliable parameter storage (e.g., calibration data, usage counters) over the full operational lifetime of equipment using the R5F1211AGSP#30.
Can the R5F1211AGSP#30 operate reliably at 105°C ambient temperature?
Yes, the R5F1211AGSP#30 is specified for industrial-grade operation from −40°C to +105°C (G-grade). This rating is validated across all core functions-including CPU execution, flash read/write, ADC conversion, CTSU operation, and RTC accuracy-under full VDD = 2.4–5.5 V conditions. Thermal derating is not required, making the R5F1211AGSP#30 suitable for sealed enclosures or high-ambient environments such as industrial control cabinets or automotive under-hood auxiliary modules.
