For engineers reviewing the R5F51306BGFM#30 datasheet, R5F51306BGFM#30 pinout, R5F51306BGFM#30 application, or R5F51306BGFM#30 equivalent, this MCU delivers deterministic real-time performance in compact 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), supports 1.8–5.5 V single-supply operation, and integrates ELC-driven event-triggered peripheral coordination without CPU wake-up - critical for battery-powered and energy-certified designs.

Technical Context

The R5F51306BGFM#30 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling 1-cycle multiplication and fast interrupt response. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for accuracy monitoring.

Peripheral integration centers on event-driven autonomy: ELC links 47 event sources across timers, ADC, and communication modules; DTC enables interrupt-triggered DMA transfers; and MPC allows flexible pin function assignment across 52 GPIOs. The device supports software standby mode with 0.37 µA supply current and 4.8 µs wake-up time.

FAQ

What is the maximum operating frequency and core performance of the R5F51306BGFM#30?

The R5F51306BGFM#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance using the 32-bit RX CPU core. Its 5-stage pipeline, single-cycle multiplication unit, and variable-length instruction set enable efficient real-time control execution. This performance level is validated across the full –40°C to +105°C temperature range specified for the G-grade R5F51306BGFM#30.

Does the R5F51306BGFM#30 support capacitive touch sensing, and how many keys can it handle?

Yes, the R5F51306BGFM#30 integrates a Capacitive Touch Sensing Unit (CTSUa) supporting up to 32 keys using the mutual capacitance method in its 64-pin LFQFP package. This capability is confirmed in Table 1.2 of the datasheet, which specifies "32 channels" for 64-pin variants. The R5F51306BGFM#30 uses TS0–TS31 pins for touch electrode connections and includes built-in noise suppression and auto-calibration features.

What low-power modes are available on the R5F51306BGFM#30, and what is the lowest supply current?

The R5F51306BGFM#30 supports three low-power consumption modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode, the supply current is 0.37 µA (typical) with the low-power timer (LPT) active - verified in the "Low power design and architecture" section of the datasheet. Wake-up time from this mode is 4.8 µs, enabling rapid responsiveness in energy-constrained applications.

Is the R5F51306BGFM#30 qualified for industrial temperature operation?

Yes, the R5F51306BGFM#30 is rated for operation from –40°C to +105°C, as indicated by the "G" suffix in its part number per Figure 1.1 of the datasheet. This G-grade qualification makes it suitable for under-hood automotive body electronics, industrial motor drives, and outdoor equipment where extended thermal stability is required - distinct from the D-grade (–40°C to +85°C) variants.

What communication interfaces does the R5F51306BGFM#30 include, and how many channels are supported?

The R5F51306BGFM#30 includes SCI (6 channels), RSPI (1 channel), and I²C (1 channel) interfaces - totaling up to 6 concurrent serial communication paths. Per Table 1.2, the 64-pin package supports SCI0, SCI1, SCI5, SCI6, SCI8, SCI9 (SCIg), plus SCI12 (SCIh), RSPIA, and RIIC0. All interfaces operate at full 32 MHz peripheral clock speed, with SCI supporting asynchronous, clock-synchronous, and smart card modes.
