Product details

The 32 MHz clock rate is the RL78/G14's maximum operating frequency, giving enough headroom for a single-loop motor-control cycle or a LIN bus message frame without starving the application. The 128 KB Flash is the firmware store; for a typical industrial sensor hub or a small HMI, that capacity holds the RTOS kernel, communication stacks, and application code with margin for one or two field-update cycles. The 16K x 8 RAM supports moderate data buffering — enough for a Modbus RTU buffer or a few PID control variables — but not a frame buffer or extensive logging. The integrated 8K x 8 EEPROM eliminates the external serial EEPROM from the BOM for calibration constants and fault logs.

If a second-source or pin-compatible alternate is needed, the RL78/G14 family includes density and package variants — but no official cross-reference to a different vendor is recorded.

Frequently asked questions

What is the closest pin-compatible alternative to R5F104BGGFP#10?

The RL78/G14 family includes multiple Flash and RAM density options in the same 32-LQFP package, such as variants with 64 KB or 256 KB Flash. No specific alternate MPN is recorded as an official replacement, but the same-package density siblings are pin-compatible across the series.
