Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGDFB#50 | Same core/peripherals, but 64-pin LFQFP (0.5-mm pitch) package - smaller footprint, tighter layout constraints | Preferred where board space is limited and reflow profile supports fine-pitch QFP | Select when PCB real estate is constrained and assembly process supports 0.5-mm pitch |
| R5F101LGDFB#50 | Omits data flash (0 KB); retains same 512 KB code flash, 32 KB RAM, and peripheral set | Suitable for cost-sensitive applications where non-volatile parameter storage is handled externally | Choose when data flash is unnecessary and BOM cost reduction is prioritized over field-upgrade capability |
Compared with R5F100LGDFA#50, R5F100LGDFB#50 offers identical functionality in a denser package requiring tighter layout tolerances, while R5F101LGDFB#50 removes data flash to lower unit cost - making it viable only when external NV memory or factory-programmed parameters suffice.

Yes, the R5F100LGDFA#50 integrates 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) with background operation (BGO) support. This allows concurrent program execution and data flash rewriting - critical for secure firmware updates and parameter logging without system interruption. The R5F100LGDFA#50 supports voltage-range programming from 1.8 V to 5.5 V.
What low-power modes does the R5F100LGDFA#50 support, and what is its lowest active current consumption?
The R5F100LGDFA#50 supports HALT, STOP, and SNOOZE modes. Its lowest active current is 0.57 μA in STOP mode with only RTC and LVD enabled - ideal for battery-backed timekeeping and wake-on-event applications. Active-mode current is 66 μA/MHz, optimized for energy-constrained industrial and sensor deployments. The R5F100LGDFA#50 maintains full register retention and fast wake-up in all low-power states.
How many analog input channels and what ADC resolution does the R5F100LGDFA#50 provide?
The R5F100LGDFA#50 features a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and integrated temperature sensor - both usable in HS (high-speed main) mode. This ADC configuration supports precision sensor interfacing in industrial monitoring and metering applications without external reference or signal conditioning. The R5F100LGDFA#50 supports simultaneous sampling across multiple channels via hardware triggers.
What communication interfaces are integrated into the R5F100LGDFA#50, and which support LIN bus protocol?
The R5F100LGDFA#50 integrates UART, I²C, CSI (Renesas' SPI-compatible interface), and simplified I²C modules. UART channels explicitly support LIN bus protocol (LIN 2.2 compliant), enabling direct integration into automotive body electronics and industrial networks requiring standardized serial communication. Up to four UART channels are available, with dedicated LIN transceiver support on selected pins. The R5F100LGDFA#50 requires no external LIN transceiver for basic node implementation.
