It integrates 16-bit timers, 10-bit ADC (26 channels), UART/I²C/CSI interfaces, RTC, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in HVAC, motor drives, and smart sensors.

For engineers reviewing the R5F100MGGFA#30 datasheet, R5F100MGGFA#30 pinout, R5F100MGGFA#30 application, or R5F100MGGFA#30 equivalent, key selection criteria include its 80-pin LQFP package, integrated data flash with background rewrite capability, 10-bit ADC resolution across 26 analog inputs, and support for LIN-bus via UART - all critical for cost-sensitive, low-power industrial firmware upgrades and sensor fusion designs.

Technical Context

The R5F100MGGFA#30 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory architecture includes separate code flash (128 KB, 1 KB blocks), data flash (8 KB, 1M write cycles), and SRAM (12 KB), with on-chip debug and self-programming including boot swap and flash shield window functions.

Power management includes HALT, STOP, and SNOOZE modes; the on-chip voltage detector offers 14 selectable LVD levels with interrupt/reset options. Peripheral integration features 16 × 16-bit timers, one 12-bit interval timer, one real-time clock with calendar/alarm/correction, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100MGGFA#30?

The R5F100MGGFA#30 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 41 DMIPS. This performance level supports real-time tasks such as PID control, sensor fusion, and protocol stack processing without external acceleration. The oscillator maintains ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C, ensuring timing stability in variable conditions. R5F100MGGFA#30's CISC architecture with 3-stage pipeline enables efficient code density and deterministic interrupt response.

Does the R5F100MGGFA#30 support LIN communication, and how is it implemented?

Yes, the R5F100MGGFA#30 supports LIN communication through its UART peripheral, which includes LIN-bus protocol functionality per the datasheet. It uses standard UART pins (e.g., P11 for RxD) with built-in LIN-specific features like sync byte detection and checksum calculation. No external LIN transceiver is required for basic node operation, though physical layer compliance depends on external driver selection. R5F100MGGFA#30's UART also supports automatic baud rate adjustment and break detection essential for LIN master/slave roles.

How much data flash is available on the R5F100MGGFA#30, and what are its endurance and voltage requirements?

The R5F100MGGFA#30 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) and operable with VDD from 1.8 V to 5.5 V. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - critical for firmware updates and parameter storage without halting system operation. The flash library reserves RAM starting at address FAF00H, and R5F100MGGFA#30's security features include flash shield window and block-level write protection.

What low-power modes does the R5F100MGGFA#30 support, and what is its lowest current consumption?

The R5F100MGGFA#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes 0.57 μA - enabling multi-year battery life in metering and sensor applications. HALT mode draws 66 μA/MHz during active operation, balancing performance and efficiency. Wake-up sources include external interrupts, RTC alarms, and LVD events. All modes retain RAM content and register states, and R5F100MGGFA#30's power-on-reset and voltage detector ensure reliable startup under brownout conditions.

Is the R5F100MGGFA#30 pin-compatible with other RL78/G13 variants in the same package?

Yes, the R5F100MGGFA#30 shares identical pinout and footprint with all other 80-pin LQFP-0.65mm RL78/G13 devices, including R5F100MFDFA#30 and R5F100MHGFA#30. Function mapping per pin is consistent across the family, enabling hardware reuse across different memory/configurations. However, peripheral enablement (e.g., number of UART channels or ADC inputs) may vary by part number - verified in the "Outline of Functions" section of the R01DS0131EJ0380 datasheet. R5F100MGGFA#30's pin compatibility simplifies design scaling and inventory consolidation.
