FAQ
What is the maximum operating frequency and supply voltage range for the R5F2135CCNFP#30?
The R5F2135CCNFP#30 operates at up to 20 MHz when supplied with 2.7–5.5 V, achieving a minimum instruction execution time of 50 ns. At reduced clock speeds (e.g., 5 MHz), it supports down to 1.8 V, enabling flexible power management in battery-powered or low-voltage systems. This dual-voltage capability is confirmed in Table 1.2 of the R01DS0006EJ0100 datasheet.
Does the R5F2135CCNFP#30 support in-system programming of its flash memory?
Yes, the R5F2135CCNFP#30 supports on-chip debug and in-system flash rewriting via its integrated debug interface. The data flash (1 KB × 4 blocks) features background operation (BGO), allowing program execution from main ROM while erasing or programming flash sectors - essential for field firmware updates without system interruption.
What peripheral modules are included in the R5F2135CCNFP#30 for motor control applications?
The R5F2135CCNFP#30 includes Timer RD with complementary PWM mode for three-phase motor drive (6-pin output), Timer RC with PWM2 mode (3-pin output), and dual 8-bit DACs for analog feedback conditioning. Its 12-channel 10-bit ADC supports current sensing and temperature monitoring, while LIN hardware enables communication with motor driver ICs in appliance-grade systems.
How does the R5F2135CCNFP#30 handle real-time clock functionality?
The R5F2135CCNFP#30 implements real-time clock (RTC) functionality through Timer RE, an 8-bit timer configured for seconds/minutes/hours/days-of-week counting. It uses the dedicated 32 kHz XCIN clock source, operates in low-power wait/stop modes (2.0–3.5 µA), and maintains timekeeping accuracy independent of the main CPU clock - verified in Section 1.1.2 and Figure 1.2 of the datasheet.
Is the R5F2135CCNFP#30 pin-compatible with other members of the R8C/35C Group?
Yes, all R8C/35C Group MCUs, including R5F2135CCNFP#30, share the identical 52-pin LQFP (PLQP0052JA-A) package and pin assignment per Figures 1.3 and Tables 1.4–1.5. Memory size variations (e.g., R5F21358CNFP vs. R5F2135CCNFP#30) do not affect pinout, enabling hardware reuse across firmware variants with different code footprints.
