FAQ

What is the maximum operating frequency and core performance of the R5F10EGCANA#20?

The R5F10EGCANA#20 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS. Its RL78 CPU core executes 86% of instructions in 1–2 clock cycles, with hardware multiply (16×16→32-bit in 1 cycle) and MAC (16×16→32-bit in 2 cycles) accelerating control algorithms. This performance is confirmed in the R01DS0151EJ0230 datasheet Section 1.1.

Does the R5F10EGCANA#20 support real-time clock functionality with calendar and alarm features?

Yes, the R5F10EGCANA#20 includes a full-featured RTC with calendar, alarm, and watch correction functions. It supports 1 Hz output (RTC1HZ on P30) and operates in Halt mode drawing only 0.57 µA. The RTC uses the 32.768 kHz subsystem clock (XT1/EXCLKS) and maintains timekeeping during ultra-low-power states, as specified in Section 1.1 and Figure 1-14 of the datasheet.

How many analog input channels and what ADC resolution does the R5F10EGCANA#20 provide?

The R5F10EGCANA#20 features a 12-bit successive approximation ADC with up to 28 input channels (ANI0–ANI30, excluding gaps). Conversion time is 3.375 µs, and it supports operation down to 1.6 V supply. An internal 1.45 V reference and dedicated AVREFP/AVREFM pins enable high-accuracy measurements without external references, per Section 1.1 and Table 1-1.

What communication interfaces are available on the R5F10EGCANA#20 and how are they configured?

The R5F10EGCANA#20 supports up to 6 serial interfaces: 3 UARTs, 2 I²C buses, and 1 CSI (Simplified SPI). These are distributed across two serial array units and configured via the Peripheral I/O Redirection Register (PIOR), allowing dynamic pin assignment. For example, P10/P11/P12 can serve as SCK00/SI00/SO00 (CSI0) or SCL00/SDA00/TxD0 (I²C0/UART0), as detailed in Section 1.3.3 and Figure 1-14.

What package type and pin count does the R5F10EGCANA#20 use, and what are its thermal characteristics?

The R5F10EGCANA#20 uses a 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch) with an exposed die pad recommended to be connected to VSS. It is rated for industrial temperature range (−40°C to +105°C), with thermal resistance θ_JA of 40°C/W typical. The package supports reflow soldering per JEDEC J-STD-020, as documented in Section 1.2 and Package Code "NA" in Figure 1-1.
