For engineers reviewing the R5F5210BBDFP#30 datasheet, R5F5210BBDFP#30 pinout, R5F5210BBDFP#30 application, or R5F5210BBDFP#30 equivalent, key selection criteria include its 100-pin LQFP package (PLQP0100KB-A), 50 MHz max frequency with 1.62–5.5 V supply range, integrated RTC with deep software standby wake-up, and dual watchdog architecture (WDTA + IWDT) for fail-safe operation.

Technical Context

The R5F5210BBDFP#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It supports little-endian or big-endian data arrangement and includes a 64-bit accumulator for single-cycle 32×32-bit multiplication results.

Its clock system integrates PLL, main/sub-clock oscillators, on-chip high/low-speed oscillators, and IWDT-dedicated oscillator, with independent clock domains (ICLK up to 50 MHz, PCLK up to 32 MHz, BCLK up to 12.5 MHz, FCLK up to 32 MHz). The ELC enables direct event-triggered peripheral operation without CPU intervention, preserving low-power states during real-time tasks.

FAQ

What is the maximum operating frequency and voltage range supported by R5F5210BBDFP#30?

The R5F5210BBDFP#30 operates at a maximum frequency of 50 MHz when supplied with 2.7–5.5 V, 32 MHz at 1.8–2.7 V, and 20 MHz at 1.62–1.8 V. Its flash and SRAM operate with zero wait states across all supported frequencies and voltages, ensuring deterministic execution timing critical for real-time control loops in the R5F5210BBDFP#30.

Does R5F5210BBDFP#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F5210BBDFP#30 integrates hardware-assisted self-test features required for IEC60730 Class B, including A/D converter diagnostic, clock accuracy measurement (CAC), independent watchdog timer (IWDT), RAM test assist, and analog input disconnection detection - enabling certified safety firmware implementation without external components in the R5F5210BBDFP#30.

How many communication interfaces does R5F5210BBDFP#30 include, and what are their key capabilities?

The R5F5210BBDFP#30 includes 13 SCI channels (supporting asynchronous, clock-synchronous, and smart card modes), 1 RIIC interface (400 kbps, SMBus-compatible), and 1 RSPI channel (16 Mbps master/slave). All support LSB/MSB-first transfer, programmable bit widths (8–32 bits), and double-buffered operation - providing flexible connectivity for industrial fieldbus, sensor networks, and display interfaces in the R5F5210BBDFP#30.

What low-power modes are available on R5F5210BBDFP#30, and which peripherals remain active in deep software standby?

The R5F5210BBDFP#30 offers four low-power modes: sleep, all-module clock stop, software standby, and deep software standby. In deep software standby, only the sub-clock oscillator and RTC remain active - enabling calendar-based wake-up, alarm-triggered interrupts, and time-capture on external events while consuming minimal current, a key capability of the R5F5210BBDFP#30 for battery-backed applications.

Is R5F5210BBDFP#30 pin-compatible with other RX210 Group MCUs in the same package?

Yes, the R5F5210BBDFP#30 uses the PLQP0100KB-A 100-pin LQFP package and shares identical pinout with other RX210 Group devices in that package (e.g., R5F5210ABDFP#30, R5F52108BDFP#30), including power, reset, clock, and peripheral signal assignments - enabling hardware design reuse and firmware migration paths within the R5F5210BBDFP#30 family.
