FAQ
What is the maximum operating frequency of the R5F21334CDFP#30?
The R5F21334CDFP#30 supports a maximum operating frequency of 20 MHz when powered at 2.7–5.5 V using an external crystal (XIN/XOUT) or ceramic resonator. At lower supply voltages (1.8–5.5 V), the maximum frequency is reduced to 5 MHz to maintain timing margin and stability.
Does the R5F21334CDFP#30 support in-circuit debugging?
Yes, the R5F21334CDFP#30 includes on-chip debug functionality compatible with Renesas E8/E8a emulators. Debug access is enabled via dedicated pins (RESET, MODE, and optional SWD-compatible signals), allowing full breakpoint, step-through, and register inspection capabilities without external JTAG hardware.
How many analog input channels does the R5F21334CDFP#30 have, and what is their resolution?
The R5F21334CDFP#30 integrates a 10-bit successive approximation register (SAR) A/D converter with 12 analog input channels (AN0–AN11). Each channel supports sample-and-hold operation and sweep mode for automatic sequential conversion, delivering consistent 10-bit precision across the full 1.8–5.5 V supply range.
Can the R5F21334CDFP#30 operate in ultra-low-power modes, and what are the typical currents?
Yes, the R5F21334CDFP#30 supports multiple low-power modes: wait mode draws 3.5 µA (VCC = 3.0 V, f(XCIN) = 32 kHz), and stop mode draws 2.0 µA under the same conditions. These modes retain RAM content and allow wake-up via external interrupt or RTC alarm, making them ideal for battery-backed applications.
Is the R5F21334CDFP#30 pin-compatible with other devices in the R8C/33C Group?
Yes, all R8C/33C Group MCUs-including R5F21331CDFP, R5F21332CDFP, R5F21334CDFP#30, R5F21335CDFP, and R5F21336CDFP-share identical 32-pin LQFP (PLQP0032GB-A) packaging and pinout. Firmware and PCB designs are interchangeable across the family, differing only in flash/RAM size and temperature grade.
