FAQ
What is the maximum operating frequency and CPU performance of the R5F51103AGFM#30?
The R5F51103AGFM#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. This is achieved through its 32-bit RX CPU core with five-stage pipeline and single-cycle instruction execution. The core supports 32-bit × 32-bit multiplication with 64-bit accumulation, making the R5F51103AGFM#30 suitable for real-time control algorithms requiring deterministic timing and moderate computational throughput.
Which package type and pin count does the R5F51103AGFM#30 use?
The R5F51103AGFM#30 uses the PLQP0064KB-A package: a 64-pin Low-Profile Quad Flat Package measuring 10 × 10 mm with 0.5 mm lead pitch. This package is RoHS-compliant and features Sn-only termination. Pin assignments are documented in Figure 1.3 and Table 1.5 of the R01DS0202EJ0120 datasheet, confirming compatibility with standard 64-pin QFP footprints and reflow profiles.
Does the R5F51103AGFM#30 support IEC 60730 Class B compliance?
Yes, the R5F51103AGFM#30 includes hardware features required for IEC 60730 Class B compliance: a clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, RAM test assist functions, and dual voltage detection circuits (LVDA). These are documented in the "On-chip functions for IEC 60730 compliance" section of the datasheet and enable certified safety firmware implementation without external components.
What are the A/D converter specifications for the R5F51103AGFM#30?
The R5F51103AGFM#30 integrates a 12-bit successive-approximation A/D converter (S12AD) with up to 14 input channels (AN000–AN015), minimum conversion time of 1.0 μs at 32 MHz ADCLK, and double-trigger mode for synchronized sampling. It supports scan modes (single, continuous, group), software/external/timer-triggered starts, and uses dedicated analog supply pins (AVCC0/AVSS0/VREFH0/VREFL0) to ensure noise immunity in mixed-signal applications.
How does the low-power capability of the R5F51103AGFM#30 compare across operating modes?
The R5F51103AGFM#30 offers three low-power modes: high-speed operating mode (0.1 mA/MHz), deep sleep mode, and software standby mode (0.35 μA typical). Recovery from software standby takes 4.8 μs - among the fastest in its class. These modes are controlled via the System Control Block and supported by peripheral stop functions, enabling aggressive power gating in battery-powered applications where the R5F51103AGFM#30 serves as the primary system controller.
