FAQ
What is the maximum operating frequency and supply voltage range for R5F21334ANFP?
The R5F21334ANFP operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports reduced-frequency operation down to 5 MHz at 1.8 V minimum supply. This dual-voltage/frequency capability allows flexible design trade-offs between performance and power consumption in battery- or line-powered systems. The R5F21334ANFP maintains full peripheral functionality across this entire voltage range.
Does R5F21334ANFP support in-system programming and debugging?
Yes, the R5F21334ANFP includes on-chip debug functionality and supports background operation (BGO) for data flash, enabling firmware updates and parameter writes while the CPU continues executing code. It requires only a standard Renesas E8/E10 emulator or compatible debug probe - no external programming hardware is needed for development or field updates. The R5F21334ANFP debug interface is fully compliant with Renesas' standard toolchain.
What are the key low-power features of R5F21334ANFP?
The R5F21334ANFP offers wait mode (3.5 µA @ 3.0 V/32 kHz) and stop mode (2.0 µA @ 3.0 V), both retaining RAM contents and supporting wake-up via external interrupt or RTC alarm. Its low-speed on-chip oscillator (32 kHz) powers the real-time clock and watchdog independently, allowing ultra-low-power timekeeping without external crystals. These features make the R5F21334ANFP suitable for battery-operated devices with multi-year operational requirements.
How many analog-to-digital converter channels does R5F21334ANFP provide, and what is their resolution?
The R5F21334ANFP integrates a 10-bit successive-approximation ADC with 12 input channels (AN0–AN11), including sample-and-hold and hardware sweep mode for automatic channel scanning. Input voltage range is 0–VREF, with VREF configurable externally or internally. All 12 channels are accessible simultaneously in sweep mode, enabling rapid multi-sensor acquisition critical for closed-loop control applications using the R5F21334ANFP.
Is R5F21334ANFP pin-compatible with other members of the R8C/33A Group?
Yes, all R8C/33A Group MCUs - including R5F21331ANFP, R5F21332ANFP, R5F21334ANFP, R5F21335ANFP, and R5F21336ANFP - share identical 32-pin LQFP packaging (PLQP0032GB-A) and fully compatible pinouts. Firmware and hardware designs can scale across this family by selecting different ROM/RAM configurations without PCB revision, provided the target application fits within the chosen device's memory limits. The R5F21334ANFP serves as the mid-tier option in this scalable lineup.
