For engineers reviewing the R5F51306BGFP#30 datasheet, R5F51306BGFP#30 pinout, R5F51306BGFP#30 application, or R5F51306BGFP#30 equivalent, key selection criteria include its 100-pin LFQFP package, –40°C to +105°C temperature grade (G version), integrated CTSU for self-capacitance touch keys, and dual SCI/I²C/RSPI communication support with ELC event-driven peripheral coordination.

Technical Context

The R5F51306BGFP#30 implements the RXv1 core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling single-cycle 32×32-bit multiply and 64-bit accumulator operations. Its clock system integrates HOCO (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for real-time frequency accuracy monitoring.

Peripheral coordination is managed via Event Link Controller (ELC), allowing timer-triggered ADC conversions and inter-module operation without CPU wake-up. The MCU supports three low-power modes, including software standby with 0.37 µA supply current and 4.8 µs wake-up time, driven by LPT or sub-clock.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51306BGFP#30?

The R5F51306BGFP#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS performance using the 32-bit RXv1 CPU core. Its 5-stage pipeline, single-cycle 32×32-bit multiply, and 64-bit accumulator enable deterministic real-time execution. This performance level supports multitasking RTOS deployments and responsive capacitive touch processing in the R5F51306BGFP#30.

Does the R5F51306BGFP#30 support IEC60730 functional safety compliance?

Yes, the R5F51306BGFP#30 includes hardware-assisted IEC60730 compliance features: self-diagnostic A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, RAM test support via DOC, and analog input disconnection detection. These capabilities reduce external safety component count and simplify certification for household and industrial appliances using the R5F51306BGFP#30.

How many capacitive touch channels does the R5F51306BGFP#30 support, and what configuration methods are available?

The R5F51306BGFP#30 integrates a Capacitive Touch Sensing Unit (CTSU) supporting up to 36 channels in self-capacitance mode (one pin per key) or up to 324 keys in mutual capacitance matrix mode. It supports four pattern waveform matching for remote control signal reception and includes built-in noise suppression algorithms. This capability is fully implemented in the R5F51306BGFP#30's 100-pin LFQFP package with dedicated TS0–TS35 pins.

What are the memory resources available on the R5F51306BGFP#30?

The R5F51306BGFP#30 includes 256 KB of on-chip flash memory (no wait states at 32 MHz), 32 KB of SRAM, and 8 KB of data flash rated for 1,000,000 program/erase cycles. Flash supports 1.8-V programming and stores both instructions and operands; data flash enables reliable parameter storage and firmware updates. All memory blocks operate without wait states, ensuring deterministic timing in the R5F51306BGFP#30.

What communication interfaces are integrated into the R5F51306BGFP#30?

The R5F51306BGFP#30 integrates seven serial channels: six SCIg (SCI0,1,5,6,8,9) and one SCIh (SCI12), one I²C bus interface (RIICa), and one RSPI channel. These support asynchronous, clock-synchronous, smart card, SMBus, SPI, and LIN protocols - with baud rate flexibility, LSB/MSB-first transfer, and up to 16 Mbps RSPI speed. This comprehensive set is native to the R5F51306BGFP#30 and requires no external transceivers for most industrial and consumer links.
