Technical Context

The R5F51101AGFM#30 implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply operations. It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 65 interrupt vectors.

Its clock system includes independent high-speed (32 MHz ±1%), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz) oscillators, with Clock Accuracy Measurement (CAC) circuitry and configurable ICLK/PCLK/FCLK domains. Peripheral clocking supports PCLK/1–PCLK/1024 timer prescaling and MTU2-triggered A/D conversion start.

FAQ

What is the maximum operating frequency and associated performance of the R5F51101AGFM#30?

The R5F51101AGFM#30 operates at a maximum frequency of 32 MHz when powered at 2.7–3.6 V, delivering 50 DMIPS of processing performance. Its RX CPU core achieves this with a five-stage pipeline, single-cycle 32×32 multiply, and ultra-compact instruction encoding. The R5F51101AGFM#30 sustains full-speed execution with zero wait states on both 32 Kbytes flash and 10 Kbytes SRAM.

Does the R5F51101AGFM#30 support IEC 60730 Class B compliance out of the box?

Yes, the R5F51101AGFM#30 integrates dedicated hardware for IEC 60730 Class B compliance, including a Clock Accuracy Measurement (CAC) circuit, Independent Watchdog Timer (IWDT) with dedicated 15 kHz oscillator, RAM test assist functions, and dual voltage detection circuits. These features enable certified safety monitoring without external components, and the R5F51101AGFM#30 is explicitly documented for use in safety-critical appliance and industrial control applications.

What package type and pin count does the R5F51101AGFM#30 use?

The R5F51101AGFM#30 uses the PLQP0064KB-A package: a 64-pin Low-Profile Quad Flat Package with 10 × 10 mm body size and 0.5 mm pin pitch. This package is RoHS-compliant, lead-free (Sn-only terminal finish), and supports standard reflow soldering. The R5F51101AGFM#30 pinout includes 50 general-purpose I/Os, 14 dedicated A/D inputs, and multiplexed peripheral functions mapped across all 64 pins.

How does the R5F51101AGFM#30 manage low-power operation in battery-powered systems?

The R5F51101AGFM#30 supports three low-power modes, with software standby mode drawing just 0.35 µA typical current and enabling wake-up in 4.8 µs. It combines this with a 32.768 kHz sub-clock oscillator for RTC calendar mode, programmable voltage detection thresholds, and peripheral module stop control. In battery-powered systems, the R5F51101AGFM#30 can sleep between sensor reads and maintain accurate timekeeping - extending operational life significantly.

Can the R5F51101AGFM#30 perform simultaneous A/D conversions triggered by multiple sources?

Yes, the R5F51101AGFM#30 supports A/D conversion start via software trigger, external pin (ADTRG0#), or timer event (MTU2 channel). Its S12AD module allows scan-mode sequencing across up to 14 channels, and the double-trigger mode captures duplicate samples for validation. This enables synchronized sampling - for example, triggering conversions on MTU2 edge events while maintaining background calibration - and the R5F51101AGFM#30 guarantees 1.0 µs minimum conversion time per channel at 32 MHz ADCLK.
