FAQ
What is the maximum operating frequency and instruction execution time of the R5F12017ASP#70?
The R5F12017ASP#70 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, yielding a minimum instruction execution time of 0.0625 μs under those conditions. This timing assumes the RL78 CPU core's 3-stage pipeline is fully utilized and no wait states are inserted. The actual achievable frequency depends on VDD voltage and ambient temperature, with guaranteed operation across 2.4–5.5 V and −40°C to +85°C.
Does the R5F12017ASP#70 support external crystal oscillation?
No, the R5F12017ASP#70 does not support external crystal (X1/X2) oscillation. As a 10-pin LSSOP variant in the RL78/G15 family, it relies solely on its internal high-speed (1–16 MHz) and low-speed (15 kHz) on-chip oscillators. External crystal functionality is reserved for 16-pin and 20-pin packages such as R5F12047ASP#70 and R5F12067ASP#70 per the RL78/G15 datasheet section 1.6.
How many analog input channels does the R5F12017ASP#70 provide, and what is their resolution?
The R5F12017ASP#70 provides four analog input channels (ANI0–ANI3) with selectable 8-bit or 10-bit resolution. These channels are supported by an internal 0.815 V reference voltage and operate across the full VDD range of 2.4 V to 5.5 V. The ADC is integrated into the 10-pin LSSOP package without requiring external components for basic ratiometric measurements.
Can the R5F12017ASP#70 perform self-programming of its flash memory?
Yes, the R5F12017ASP#70 supports self-programming of both code flash and data flash memory without requiring an external programmer. It implements this via on-chip firmware routines that handle erase-before-write operations and include flash shield window protection. However, background operation (BGO) is not supported - meaning code execution must halt during data flash writes, as confirmed in the R01DS0420EJ0140 datasheet section 1.1.
What low-power modes are available on the R5F12017ASP#70, and how do they affect current consumption?
The R5F12017ASP#70 offers HALT and STOP low-power modes. In HALT mode, the CPU stops but peripherals remain active, drawing ~54 µA/MHz at 125°C (typical). In STOP mode, both CPU and most peripherals halt, reducing current to sub-µA levels - ideal for battery-backed applications. Both modes support wake-up via external interrupts (e.g., INTP0–INTP7) or timer events, enabling responsive yet energy-efficient operation.
