For engineers reviewing the R5F51406AGFN#30 datasheet, R5F51406AGFN#30 pinout, R5F51406AGFN#30 application, or R5F51406AGFN#30 equivalent, key selection criteria include its −40°C to +105°C extended temperature rating, 80-pin LFQFP package with 69 GPIOs, hardware AES/RNG encryption option (not enabled in this variant), and real-time clock with calendar mode - all critical for rugged embedded designs requiring functional safety compliance.

Technical Context

The R5F51406AGFN#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering 204 CoreMark at 48 MHz. It integrates a dedicated low-power timer (LPT) running during software standby and supports event-driven operation via the Event Link Controller (ELC) to initiate peripheral actions without CPU wake-up.

Its clock system includes high-speed on-chip oscillator (48 MHz ±1%), PLL, sub-clock (32.768 kHz), and Clock Accuracy Measurement Circuit (CAC). The MCU supports four low-power modes, with software standby current as low as 0.25 µA (typ.) and recovery time of 6.2 µs using HOCO 32 MHz.

FAQ

What is the maximum operating frequency and core type of the R5F51406AGFN#30?

The R5F51406AGFN#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz, achieving 204 CoreMark performance. Its Harvard architecture, 5-stage pipeline, and variable-length instruction set enable deterministic real-time execution. The R5F51406AGFN#30 uses on-chip high-speed oscillators (±1% accuracy) and PLL support to maintain timing integrity across voltage and temperature variations.

Does the R5F51406AGFN#30 include hardware encryption capabilities?

No, the R5F51406AGFN#30 does not include hardware encryption modules. Its part number suffix 'A' indicates absence of AESA and RNGA blocks. For applications requiring AES-128/256 or true random number generation, the R5F51406BGFN#30 (suffix 'B') is the functionally identical alternative with those accelerators enabled. The R5F51406AGFN#30 retains all other peripherals including CAN, CTSU, and IEC60730 diagnostic features.

What package type and pin count does the R5F51406AGFN#30 use?

The R5F51406AGFN#30 uses an 80-pin Low-Profile Quad Flat Package (LFQFP) designated PLQP0080KB-B, measuring 12 mm × 12 mm with 0.5 mm pitch and an exposed thermal pad. This package provides 69 general-purpose I/O pins, 4 5-V-tolerant inputs, and 47 open-drain outputs - optimized for industrial PCB layouts requiring noise immunity and thermal dissipation. The R5F51406AGFN#30 shares footprint compatibility only with other 80-pin RX140 variants like R5F51406ADFN#30.

What is the operating temperature range specified for the R5F51406AGFN#30?

According to Renesas documentation, the R5F51406AGFN#30 is rated for operation from −40°C to +105°C (G-grade). This extended temperature range supports deployment in demanding environments such as motor drive cabinets, outdoor energy meters, and under-hood automotive subsystems. The R5F51406AGFN#30 maintains full specification compliance - including 48 MHz operation, A/D conversion accuracy, and RTC functionality - across this entire range.

Which communication interfaces are supported by the R5F51406AGFN#30?

The R5F51406AGFN#30 supports CAN 2.0B (1 Mbps), six SCI channels (with LIN/SCIF extensions), one I²C bus interface (400 kbps, SMBus-compatible), one RSPI (16 Mbps), and one RIIC module. All interfaces are accessible via dedicated pins in its 80-pin LFQFP package. The R5F51406AGFN#30's ELC allows event-triggered transfers between these peripherals without CPU intervention - for example, linking MTU2 timer overflow to SCI transmission start.
