For engineers reviewing the R5F100GJDFB#50 datasheet, R5F100GJDFB#50 pinout, R5F100GJDFB#50 application, or R5F100GJDFB#50 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), on-chip debug support, self-programming flash with boot swap, and hardware DMA for deterministic peripheral handling in resource-constrained embedded systems.
Technical Context
The R5F100GJDFB#50 implements the RL78 CPU core 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), and includes dedicated low-power modes (HALT, STOP, SNOOZE) managed via on-chip power-on-reset and voltage detector with 14-level LVD interrupt/reset selection.
It integrates dual serial interface sets: up to 4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels; plus 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar/alarm/correction, and 1× watchdog timer running on dedicated low-speed oscillator.

Yes, R5F100GJDFB#50 supports full in-system programming via on-chip debug interface and includes flash shield window functionality to protect designated memory regions from overwrite. It enables secure firmware updates using boot swap capability - allowing validated new firmware to be loaded into inactive flash bank while legacy code remains operational - ensuring fail-safe field upgrades without external programming hardware.
What analog features are integrated into R5F100GJDFB#50, and how many channels does the ADC support?
R5F100GJDFB#50 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels, internal 1.45 V reference voltage, and an on-die temperature sensor. The ADC supports hardware averaging, scan mode, and flexible trigger sources (timer, external pin, software). The temperature sensor is usable only in HS (high-speed main) mode and provides factory-calibrated output for ambient temperature estimation within ±2°C accuracy.
Is R5F100GJDFB#50 qualified for industrial temperature operation, and what is its specified range?
Yes, R5F100GJDFB#50 is qualified for industrial temperature operation with a specified ambient operating range of −40°C to +105°C, indicated by the "G" suffix in the part number. This rating applies across all electrical specifications including flash endurance, ADC accuracy, and timing parameters, making it suitable for deployment in harsh environments such as motor drives, factory automation controllers, and outdoor sensor enclosures.
Which serial communication interfaces are available on R5F100GJDFB#50, and are they LIN-bus compatible?
R5F100GJDFB#50 provides up to 4 UART channels with built-in LIN-bus protocol support (including break detection, sync field handling, and checksum calculation), up to 10 I²C/Simplified I²C channels (master/slave), and up to 8 CSI (SPI-compatible) channels.
