Technical Context

The R5F51406BDNE#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering 204 CoreMark at 48 MHz. It integrates an IEEE-754-compliant 32-bit FPU, 32-bit multiplier, and 32-bit divider with two-cycle latency.

Its low-power architecture supports four modes including software standby (0.25 µA typ.) with 6.2 µs wake-up from HOCO 32 MHz, and includes ELC for event-driven peripheral coordination without CPU intervention - enabling deterministic response in battery-powered control loops.

FAQ

What is the maximum operating frequency and core type of the R5F51406BDNE#30?

The R5F51406BDNE#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz. It achieves 204 CoreMark at that speed and includes a 5-stage pipeline, variable-length instruction set, and IEEE-754-compliant floating-point unit. The R5F51406BDNE#30 uses on-chip high-speed oscillators (HOCO) or external crystals up to 20 MHz with PLL multiplication to reach 48 MHz, ensuring deterministic real-time performance for industrial control tasks.

Does the R5F51406BDNE#30 include hardware encryption capabilities?

Yes, the R5F51406BDNE#30 includes the AESA hardware accelerator supporting AES-128 and AES-256 in ECB, CBC, and CTR modes, plus the RNGA true random number generator. These modules are enabled by the "B" suffix in the part number and are absent in "A" variants like R5F51406ADNE#30. The R5F51406BDNE#30 executes 128-bit AES encryption in 176 cycles, enabling efficient secure boot and OTA firmware updates without CPU overhead.

What is the package type and pin count of the R5F51406BDNE#30?

The R5F51406BDNE#30 uses the PWQN0048KC-A package: a 48-pin HWQFN with 7 × 7 mm body size and 0.5 mm pitch, including an exposed thermal pad. This package is specified for –40°C to +85°C operation (D-grade) and supports 5-V-tolerant inputs on designated pins. The "NE" in the part number explicitly denotes this HWQFN variant per Renesas' naming convention in R01DS0379EJ0120.

How many A/D converter channels does the R5F51406BDNE#30 support, and what is its conversion speed?

The R5F51406BDNE#30 integrates the S12ADE 12-bit A/D converter with 11 external input channels and 1 internal channel (temperature sensor). Its minimum conversion time is 0.67 µs per channel when ADCLK runs at 48 MHz. The R5F51406BDNE#30 supports scan modes, sampling time per channel configuration, conversion result comparison, and double-trigger mode for motor control - all confirmed in Table 1.2 of the datasheet for the 48-pin HWQFN variant.

Does the R5F51406BDNE#30 support CAN communication, and if so, which standard?

Yes, the R5F51406BDNE#30 includes one RSCAN CAN module compliant with ISO11898-1, supporting both standard and extended frames at up to 1 Mbps. This capability is retained in the 48-pin HWQFN package per Table 1.2, distinguishing it from lower-pin-count variants like R5F51403ADNE#30. The R5F51406BDNE#30 uses 16 mailboxes and supports message filtering and loopback testing - essential for industrial fieldbus integration.
