Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GEAFP#V0 | LQFP-48 package (7 mm × 7 mm, 0.5 mm pitch), same memory and peripherals | Better suited for through-hole prototyping or manual rework; larger footprint than HWQFN | Select when board assembly uses LQFP-compatible pick-and-place or requires thermal pad accessibility |
| R5F101GEANA#W0 | No data flash (0 KB), identical core, flash, RAM, and peripheral set otherwise | Targeted at cost-sensitive applications where firmware-only storage suffices | Choose when data logging or field-upgradable parameter storage is unnecessary |
Compared with R5F100GEANA#W0, R5F100GEAFP#V0 offers identical functionality in a more serviceable package but increases PCB area and thermal resistance, while R5F101GEANA#W0 removes data flash to reduce cost and power - making it suitable only where non-volatile parameter storage is handled externally.

FAQ
What is the maximum operating temperature rating for the R5F100GEANA#W0?
The R5F100GEANA#W0 is rated for industrial operation from –40°C to +105°C (G-grade), validated across its full voltage range (1.6–5.5 V) and all specified clock frequencies. This rating applies to the complete device - including flash programming, ADC accuracy, and RTC functionality - under continuous operation per Renesas datasheet R01DS0131EJ0380.
Does the R5F100GEANA#W0 support in-system programming without external hardware?
Yes, the R5F100GEANA#W0 supports full in-system programming via its on-chip debug interface using only the CLKP/CLKM and RESET pins. Its self-programming capability - including boot swap and flash shield window - enables secure firmware updates directly in the target application without requiring an external programmer or chip removal.
How many serial communication interfaces does the R5F100GEANA#W0 provide?
The R5F100GEANA#W0 provides up to 8 CSI (SPI-compatible), 4 UART/LIN channels, and 10 I²C interfaces - with physical pin allocation depending on package variant. For the 48-pin HWQFN (R5F100GEANA#W0), all three interface types are simultaneously available, enabling concurrent communication with multiple sensors, displays, and bus networks.
Can the R5F100GEANA#W0 operate reliably at 1.6 V supply voltage?
Yes, the R5F100GEANA#W0 is fully specified to operate down to 1.6 V across its entire functional range - including 32 MHz operation, ADC conversion, RTC calendar function, and flash read/write. At 1.6 V, the maximum supported frequency is 16 MHz, and all low-power modes (HALT, STOP, SNOOZE) remain fully operational with guaranteed current consumption.
Is there hardware support for real-time data logging in the R5F100GEANA#W0?
Yes, the R5F100GEANA#W0 includes background operation (BGO) for data flash, allowing the CPU to execute application code from program flash while concurrently rewriting data flash memory. This enables seamless real-time logging - such as timestamped sensor readings - without interrupting system responsiveness or timing-critical tasks.
