Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MGDFA#10 | Same 128 KB flash, 8 KB data flash, 12 KB RAM, and 80-pin LQFP package; differs only in field grade (D-grade: -40°C to +85°C vs. G-grade) | Targeted at commercial/industrial ambient environments without extended temperature requirements | Select when operating temperature does not exceed +85°C and cost optimization is prioritized over extended thermal qualification |
| R5F100MGGFB#10 | Identical memory, peripherals, and temperature rating; differs in package - 80-pin LFQFP (0.5 mm pitch) instead of LQFP (0.65 mm pitch) | Requires PCB redesign due to finer pitch and different land pattern; suited for higher-density layouts | Choose for space-constrained designs where 0.5 mm pitch footprint is acceptable and assembly capability supports fine-pitch QFP |
Compared with R5F100MGDFA#10 and R5F100MGGFB#10, the R5F100MGGFA#10 uniquely combines industrial -40°C to +105°C operation with the widely adopted 0.65 mm pitch LQFP footprint - enabling drop-in replacement in existing thermal-critical designs without layout changes or requalification.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100MGGFA#10?
The R5F100MGGFA#10 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core supports variable instruction execution time - as fast as 0.03125 μs per instruction at 32 MHz, or as slow as 30.5 μs at 32.768 kHz - enabling dynamic trade-offs between speed and power consumption. This flexibility makes the R5F100MGGFA#10 well-suited for both responsive real-time tasks and ultra-low-power sensing intervals.
Does the R5F100MGGFA#10 include integrated data flash, and what are its endurance and voltage specifications?
Yes, the R5F100MGGFA#10 includes 8 KB of on-chip data flash memory with background operation (BGO) capability. It supports 1,000,000 write/erase cycles (typical) and operates across the full VDD range of 1.8 V to 5.5 V - eliminating the need for external EEPROM in parameter storage applications. The flash library reserves RAM starting at address FAF00H for self-programming operations, and the device supports flash shield window and boot swap functions for secure firmware updates.
What low-power modes does the R5F100MGGFA#10 support, and what is the lowest achievable current draw?
The R5F100MGGFA#10 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA - making it ideal for battery-powered applications requiring years of operation on a single coin cell. HALT mode consumes 66 μA/MHz at 32 MHz, and SNOOZE mode allows selective peripheral operation (e.g., UART receive, ADC trigger) while the CPU remains asleep, reducing average system power without sacrificing responsiveness.
Can the R5F100MGGFA#10 operate across the full industrial temperature range, and what grade designation confirms this?
Yes, the R5F100MGGFA#10 is rated for continuous operation from -40°C to +105°C, confirmed by the "G" suffix in its part number - indicating Renesas' industrial-grade qualification. This extended temperature range is validated across all specified electrical parameters, including flash read/write, ADC accuracy, and oscillator stability, ensuring reliable performance in demanding environments such as factory automation, outdoor metering, and under-hood automotive subsystems.
What serial communication interfaces are integrated into the R5F100MGGFA#10, and how many channels does each support?
The R5F100MGGFA#10 integrates three serial interface types: Simplified SPI (CSI) with up to 8 channels, UART/UART with LIN-bus support across up to 4 channels, and I²C/Simplified I²C with up to 10 channels. Each interface supports flexible pin mapping and concurrent operation - for example, CSI0 can share pins with I²C0 or UART0, allowing multiplexed use of limited I/O resources. All interfaces are fully register-configurable and support standard baud rates, clock stretching (I²C), and automatic LIN header detection.
