For engineers reviewing the R5F51403AGFM#30 datasheet, R5F51403AGFM#30 pinout, R5F51403AGFM#30 application, or R5F51403AGFM#30 equivalent, key selection criteria include its –40°C to +105°C temperature rating, LFQFP-64 (10 × 10 mm, 0.5 mm pitch) package, integrated capacitive touch sensing unit supporting up to 32 keys, and hardware AES/RNG acceleration optional in B-variant parts.

Technical Context

The R5F51403AGFM#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 timing, plus background-programmable 4 KB data flash rated for 1 million erase/program cycles.

Peripherals are orchestrated via Event Link Controller (ELC) enabling interrupt-free module triggering and linked operation during CPU sleep. Clock management supports multiple oscillators (HOCO 48 MHz ±1%, LOCO 4 MHz, sub-clock 32.768 kHz), CAC for frequency accuracy measurement, and independent IWDT with dedicated 15 kHz oscillator - all contributing to IEC60730 Class B compliance support.

FAQ

What is the maximum operating frequency and core type of the R5F51403AGFM#30?

The R5F51403AGFM#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. The core uses CISC Harvard architecture with a 5-stage pipeline and variable-length instructions, enabling high code density and deterministic real-time execution - essential for the R5F51403AGFM#30's use in time-critical industrial control applications.

Does the R5F51403AGFM#30 include hardware encryption capabilities?

No, the R5F51403AGFM#30 does not include hardware encryption. Its part number suffix "A" indicates absence of the AESA (Advanced Encryption Standard Accelerator) and RNGA (True Random Number Generator) modules. These are only present in "B"-suffix variants such as R5F51403BGFx#30. For secure boot or data encryption in systems using the R5F51403AGFM#30, software-based cryptographic libraries must be implemented - a design consideration confirmed by Renesas' official product matrix and datasheet Table 1.3.

What package type and pin count does the R5F51403AGFM#30 use?

The R5F51403AGFM#30 uses a 64-pin LFQFP package designated PLQP0064KB-C, measuring 10 × 10 mm with 0.5 mm pitch. This is distinct from the 64-pin LQFP (PLQP0064GA-A, 0.8 mm pitch) and other variants in the RX140 family. The package supports standard surface-mount assembly and provides full peripheral pinout access including CAN, multiple SCI channels, MTU2 timers, and CTSU2SL touch inputs - all verified in Renesas' R01DS0379EJ0120 datasheet Section 1.2 and Figure 1.1.

How many A/D converter channels does the R5F51403AGFM#30 support, and what is its conversion speed?

The R5F51403AGFM#30 integrates a 12-bit successive-approximation A/D converter with 15 total channels: 14 external input pins plus one internal channel for temperature sensor monitoring. Minimum conversion time is 0.67 µs per channel when ADCLK runs at 48 MHz. Sampling time is programmable per channel, and the module supports scan modes, group priority control, and double-trigger mode for motor control - all documented in Section 35 of the RX140 User's Manual and confirmed in datasheet Table 1.2 for the 64-pin LFQFP variant.

Is the R5F51403AGFM#30 qualified for IEC60730 Class B compliance?

Yes, the R5F51403AGFM#30 includes dedicated hardware features to support IEC60730 Class B compliance, including self-diagnostic functions for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance via the Data Operation Circuit (DOC), and analog input disconnection detection. These are explicitly listed in the "Useful functions for IEC60730 compliance" section of the R01DS0379EJ0120 datasheet and apply to all RX140 Group devices including the R5F51403AGFM#30.
