For engineers reviewing the R5F5210BBDFB#30 datasheet, R5F5210BBDFB#30 pinout, R5F5210BBDFB#30 application, or R5F5210BBDFB#30 equivalent, key selection criteria include its 144-pin LQFP package, full peripheral set (13 SCI channels, RSPI, RIIC, MTU2/TPU timers), deep software standby with RTC wake-up, and 5-V-tolerant I/O for mixed-voltage system interfacing.

Technical Context

The R5F5210BBDFB#30 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code and single-cycle 32×32-bit multiplication. Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), high-/low-speed on-chip oscillators, and clock accuracy measurement (CAC) for timing-critical applications.

Peripheral integration includes Event Link Controller (ELC) for interrupt-free module triggering, Multi-function Pin Controller (MPC) for flexible I/O remapping, and dual timer subsystems: MTU2 (6-channel 16-bit) and TPU (6-channel 16-bit), supporting complementary PWM, phase counting, and A/D trigger generation - all operable during CPU sleep modes.

FAQ

What is the maximum operating frequency and associated DMIPS rating for the R5F5210BBDFB#30?

The R5F5210BBDFB#30 operates at a maximum frequency of 50 MHz and delivers 78 DMIPS (Dhrystone MIPS) performance. This metric reflects its optimized RX CPU core execution efficiency at full speed, validated under standard test conditions with cache enabled and no wait states on flash access. The R5F5210BBDFB#30 achieves this performance while maintaining deterministic interrupt latency and low power consumption.

Does the R5F5210BBDFB#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F5210BBDFB#30 integrates dedicated hardware features for IEC60730 Class B compliance, including self-diagnostic routines for the A/D converter, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT), RAM testing assistance, and analog input disconnection detection. These capabilities are documented in the RX210 hardware manual and require minimal firmware integration to satisfy certification requirements - no external safety monitors are needed for basic compliance.

What package type and pin count does the R5F5210BBDFB#30 use?

The R5F5210BBDFB#30 uses the PLQP0144KA-A package: a 144-pin LQFP with 20 × 20 mm body size, 0.5-mm pitch, and exposed thermal pad. This package supports the full peripheral complement of the RX210 Group - including 122 GPIOs, 13 SCI channels, RSPI, RIIC, MTU2, TPU, and all analog functions - making it the highest I/O count option in the chip version B lineup.

How much on-chip flash, SRAM, and data flash memory does the R5F5210BBDFB#30 include?

The R5F5210BBDFB#30 includes 1 Mbyte of on-chip flash memory (executed at full 50 MHz with zero wait states), 96 Kbytes of SRAM (also zero-wait-state operation), and 8 Kbytes of data flash memory rated for 100,000 erase/write cycles. The data flash is managed independently of the main flash and supports background erasing/programming without CPU interruption - ideal for storing calibration data or field-upgradable parameters.

Can the R5F5210BBDFB#30 operate from a single low-voltage supply, and what is its minimum operating voltage?

Yes, the R5F5210BBDFB#30 operates from a single supply ranging from 1.62 V to 5.5 V. At 1.62–1.8 V, it supports up to 20 MHz operation; at 1.8–2.7 V, up to 32 MHz; and at 2.7–5.5 V, full 50 MHz operation. This wide supply range allows direct interfacing with diverse power rails - including battery-backed systems and multi-rail industrial boards - without level-shifting circuitry for core logic.
