It features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, UART/I²C/CSI interfaces, and operates from 1.6–5.5 V in industrial temperature range (−40°C to +105°C). It targets battery-powered industrial sensors and smart metering systems.
For engineers reviewing the R5F100MHAFA#V0 datasheet, R5F100MHAFA#V0 pinout, R5F100MHAFA#V0 application, or R5F100MHAFA#V0 equivalent, key selection considerations include its LQFP-80 package, 192 KB code flash with self-programming, 26-channel 10-bit ADC, RTC calendar support, and industrial-grade −40°C to +105°C operation with LVD and HALT/STOP/SNOOZE low-power modes.
Technical Context
The R5F100MHAFA#V0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, 16-bit timers (12 channels), watchdog timer, and background operation for data flash rewriting while executing program code.
Its peripheral set includes 3 UART/LIN channels, 3 I²C/Simplified I²C channels, up to 8 CSI channels, DMA controller (4 channels), multiplier/divider/MAC unit, and on-chip BCD correction circuit.

FAQ
What is the maximum operating frequency and performance of the R5F100MHAFA#V0?
The R5F100MHAFA#V0 operates at up to 32 MHz with 41 DMIPS performance. Its high-accuracy on-chip oscillator supports ±1.0% tolerance across 1.8–5.5 V and −20°C to +85°C, and it can be configured for lower frequencies (e.g., 32.768 kHz) to optimize power in RTC-critical applications. This makes R5F100MHAFA#V0 suitable for both responsive control tasks and ultra-low-power monitoring roles.
Does the R5F100MHAFA#V0 include data flash memory, and what is its endurance?
Yes, the R5F100MHAFA#V0 includes 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) with background operation (BGO) support. It operates across the full VDD range of 1.8–5.5 V, enabling reliable parameter storage and firmware updates without halting application code execution-critical for R5F100MHAFA#V0 deployments in field-upgradable devices.
What low-power modes does the R5F100MHAFA#V0 support, and how low is its standby current?
The R5F100MHAFA#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA-enabling multi-year battery life in metering and sensor applications. HALT mode consumes 0.84 μA, and SNOOZE allows selected peripherals (e.g., UART, ADC) to operate during low-power sleep, making R5F100MHAFA#V0 ideal for duty-cycled wireless endpoints.
How many analog input channels does the R5F100MHAFA#V0 ADC support, and what resolution is available?
The R5F100MHAFA#V0 integrates a 10-bit successive-approximation ADC with up to 26 configurable analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor-both usable in HS (high-speed main) mode. This enables direct sensor interfacing without external references, a key advantage for R5F100MHAFA#V0 in compact industrial measurement designs.
Is the R5F100MHAFA#V0 qualified for industrial temperature operation?
Yes, the R5F100MHAFA#V0 carries the 'G' grade designation, specifying guaranteed operation from −40°C to +105°C ambient temperature. This qualification covers all core functions, peripherals, and memory-including flash read/write, ADC accuracy, and oscillator stability-making R5F100MHAFA#V0 appropriate for under-hood automotive ancillaries, factory-floor controllers, and outdoor utility equipment.
