Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LCGFB#X0 | Same package and memory, but rated for -40°C to +105°C (G grade); higher max junction temperature rating. | Required for under-hood automotive or high-ambient industrial enclosures exceeding +85°C. | Select when extended temperature range is mandatory; otherwise R5F100LCDFB#X0 offers cost and supply-chain advantage for standard industrial use. |
| R5F101LCDFB#X0 | Identical pinout and package, but lacks data flash memory (0 KB); retains same code flash, RAM, and peripherals. | Suitable where firmware updates occur only via external loader or where EEPROM emulation is unnecessary. | Choose when data logging or field firmware patching is not required - reduces cost and simplifies qualification for fixed-function controllers. |
Compared with R5F100LCGFB#X0, the R5F100LCDFB#X0 trades extended temperature tolerance for lower unit cost and broader distributor availability in industrial-grade volume; versus R5F101LCDFB#X0, it adds 8 KB of wear-rated data flash essential for parameter storage and over-the-air update staging - making it the optimal choice for field-deployable, upgradable systems.

The R5F100LCDFB#X0 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across VDD = 1.8 V to 5.5 V. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - critical for reliable firmware updates and runtime parameter logging in the R5F100LCDFB#X0.
What package type and pin count does the R5F100LCDFB#X0 use?
The R5F100LCDFB#X0 uses a 64-pin LFQFP package with 0.5 mm pitch (PLQP0064KF-A), measuring 10 mm × 10 mm with an exposed thermal pad. The #X0 suffix indicates embossed tape packaging - optimized for automated SMT assembly in high-volume industrial manufacturing lines using the R5F100LCDFB#X0.
Is the R5F100LCDFB#X0 qualified for industrial temperature range operation?
Yes, the R5F100LCDFB#X0 is qualified for industrial temperature operation from -40°C to +85°C (Grade D), as confirmed by Renesas' official datasheet R01DS0131EJ0380. It undergoes full characterization across this range for all peripherals including ADC accuracy, oscillator stability, and flash retention - ensuring reliability in factory-floor and outdoor equipment using the R5F100LCDFB#X0.
