FAQ

What is the maximum operating frequency and CPU performance of the R5F52106BGFB#30?

The R5F52106BGFB#30 operates at a maximum frequency of 50 MHz, delivering 78 DMIPS of processing performance. Its RXv1 CPU core features a 5-stage pipeline, variable-length instructions, and single-cycle 32×32-bit multiplication with 64-bit accumulator output - enabling deterministic execution of real-time control algorithms in applications like motor drive and PLC sequencing. The R5F52106BGFB#30 achieves this performance across its full −40°C to +105°C operating range.

Does the R5F52106BGFB#30 support functional safety standards such as IEC60730?

Yes, the R5F52106BGFB#30 includes hardware-assisted features for IEC60730 Class B compliance, including self-diagnostic A/D converter tests, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT), RAM test assistance, and analog input disconnection detection. These capabilities are integrated into the silicon and documented in Renesas' functional safety manual, allowing certified implementations in household appliances and industrial equipment without external safety monitors. The R5F52106BGFB#30 leverages these features to reduce software validation effort.

What package type and pin count does the R5F52106BGFB#30 use?

The R5F52106BGFB#30 uses the PLQP0144KA-A package: a 144-pin LQFP with 20 × 20 mm body size, 0.5-mm pin pitch, and exposed thermal pad. This package supports full peripheral access - including all 13 SCI channels, RSPI, RIIC, MTU2/TPU timers, and 122 GPIOs - and is rated for −40°C to +105°C operation. The R5F52106BGFB#30 shares footprint compatibility with other RX210 Group 144-pin variants, enabling scalable design reuse.

How much on-chip memory does the R5F52106BGFB#30 include, and what are its characteristics?

The R5F52106BGFB#30 integrates 256 KB of on-chip flash memory (executed at full 50 MHz with zero wait states), 32 KB of SRAM (also zero-wait-state), and 8 KB of data flash rated for 100,000 erase/write cycles. Flash supports user programming via SCI at voltages as low as 1.62 V, and both flash and SRAM operate across the full industrial temperature range. The R5F52106BGFB#30 uses this memory configuration to host real-time firmware, data logging buffers, and parameter storage without external components.

What communication interfaces are available on the R5F52106BGFB#30?

The R5F52106BGFB#30 provides 13 serial communications interface (SCI) channels supporting asynchronous, clock-synchronous, and smart card modes; 1 I2C bus interface (RIIC) capable of 400 kbps and SMBus operation; and 1 high-speed serial peripheral interface (RSPI) supporting up to 16 Mbps. All interfaces support ELC-triggered operation and are accessible via the 144-pin LQFP package. The R5F52106BGFB#30 uses these to implement multi-protocol fieldbus connectivity - e.g., Modbus RTU over SCI, sensor data aggregation via RIIC, and fast firmware updates via RSPI.
