FAQ
What is the maximum operating frequency and performance of the R5F1006EASP#X0?
The R5F1006EASP#X0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline and high-accuracy on-chip oscillator (±1.0% over -20 to +85°C). The R5F1006EASP#X0 maintains full peripheral functionality at maximum speed, including ADC conversions, UART transmission, and timer operations, making it suitable for real-time control tasks demanding deterministic timing.
Does the R5F1006EASP#X0 support in-system programming and secure firmware updates?
Yes, the R5F1006EASP#X0 supports full in-system programming via its on-chip debug interface (SWDIO/SWCLK pins) and includes flash shield window and block erase prohibition features for security. Self-programming with boot swap allows safe dual-bank firmware updates - the R5F1006EASP#X0 can validate new firmware in one bank while running from the other, then atomically switch execution upon success.
How many analog input channels does the R5F1006EASP#X0 support, and what ADC resolution is available?
The R5F1006EASP#X0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. All 20 pins on the LSSOP package support analog functions, including dedicated AVREFP/AVREFM pins for precision referencing. The ADC includes an internal 1.45 V reference and temperature sensor - both accessible directly by the R5F1006EASP#X0 without external components.
What low-power modes are available on the R5F1006EASP#X0, and what is the lowest current consumption?
The R5F1006EASP#X0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.57 μA - verified across the full -40°C to +85°C industrial temperature range. This enables multi-year battery life in always-on sensing applications. Wake-up from STOP is possible via external interrupts, RTC alarm, or peripheral events such as UART reception or ADC completion.
Is the R5F1006EASP#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 20-pin LSSOP variants - including R5F1006A/C/D/E/F/G and R5F1016A/C/D/E/F/G - share identical pinouts and electrical characteristics. This allows direct substitution within the same package family for memory scaling or feature enablement (e.g., upgrading from R5F1006DASP#X0 to R5F1006EASP#X0 requires no PCB changes, only firmware requalification).
