It targets low-power industrial control and sensor-edge applications requiring IEC60730 compliance and extended temperature operation.

For engineers reviewing the R5F51405AGNE#30 datasheet, R5F51405AGNE#30 pinout, R5F51405AGNE#30 application, or R5F51405AGNE#30 equivalent, key selection factors include its HWQFN-48 package (7 × 7 mm, 0.5 mm pitch), –40°C to +105°C operating range, integrated AES/RNG encryption option, and real-time clock omission in this variant-critical for time-stamped control and secure firmware updates.

Technical Context

The R5F51405AGNE#30 implements the RXv2 CPU core with IEEE-754-compliant 32-bit FPU, 204 CoreMark score at 48 MHz, and on-chip divider completing 32-bit ÷ 32-bit in two cycles. Its memory subsystem includes no-wait-state SRAM and flash with 32 MHz ≤ access, plus background operation (BGO) support for data flash programming during runtime.

Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables 48 event sources to trigger module actions-including A/D conversion start, PWM output, and timer cascading-without CPU intervention or interrupt latency, while the Multi-function Pin Controller (MPC) allows flexible I/O function assignment across 39 general-purpose pins.

FAQ

What is the maximum operating frequency and core type of the R5F51405AGNE#30?

The R5F51405AGNE#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz. It achieves 204 CoreMark at this speed and includes an IEEE-754-compliant 32-bit floating-point unit (FPU), on-chip 32-bit multiplier, and two-cycle 32-bit divider-enabling high-efficiency real-time computation for motor control and sensor processing tasks within the R5F51405AGNE#30.

Does the R5F51405AGNE#30 include a real-time clock (RTC) module?

No, the R5F51405AGNE#30 does not include a real-time clock (RTCB) module. According to Table 1.2 in the datasheet, RTC functionality is omitted in 48-pin variants such as the R5F51405AGNE#30, regardless of temperature grade. This omission reduces die size and cost for applications where calendar/time-of-day tracking is handled externally or is unnecessary-consistent with the R5F51405AGNE#30's focus on compact, low-power control.

What package type and pin count does the R5F51405AGNE#30 use?

The R5F51405AGNE#30 uses the PWQN0048KC-A package: a 48-pin wettable flank QFN measuring 7 × 7 mm with 0.5 mm pitch and an exposed thermal pad. This package supports automated optical inspection (AOI) and provides superior thermal dissipation over standard QFN-critical for sustained 48 MHz operation in enclosed industrial environments where the R5F51405AGNE#30 is deployed.

Which communication interfaces are supported by the R5F51405AGNE#30?

The R5F51405AGNE#30 supports one CAN channel (ISO 11898-1, up to 1 Mbps), five SCI channels (asynchronous, clock-synchronous, Smart Card modes), one I2C bus interface (400 kbps, SMBus compatible), and one RSPI channel (16 Mbps master/slave). It does not include the SCIh or RTCB modules found in larger-package RX140 variants-confirming its role as a focused, cost-optimized node controller within the R5F51405AGNE#30 family.

Is hardware encryption available on the R5F51405AGNE#30?

Yes, the R5F51405AGNE#30 includes optional hardware encryption: the Advanced Encryption Standard Accelerator (AESA) supporting AES-128 and AES-256 in ECB, CBC, and CTR modes, plus a True Random Number Generator (RNGA). These modules are present in "G"-grade (–40°C to +105°C) variants with "B" prefix (e.g., R5F51405BGNE#30), but the R5F51405AGNE#30 uses "A" prefix indicating encryption is not implemented-making it suitable for non-security-critical applications where cost and power efficiency are prioritized over cryptographic capability.
