For engineers reviewing the R7F100GGK2DFB#BA0 datasheet, R7F100GGK2DFB#BA0 pinout, R7F100GGK2DFB#BA0 application, or R7F100GGK2DFB#BA0 equivalent, this page delivers verified specifications, package mapping, real-world use cases, and validated alternative options - all aligned to the official RL78/G23 Rev.1.40 datasheet and Renesas ordering documentation.
Technical Context
The R7F100GGK2DFB#BA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates SNOOZE mode sequencer (SMS) for autonomous low-power sensor polling and Event Link Controller (ELCL) for hardware-triggered peripheral coordination without CPU intervention.
Its power management includes HALT/STOP/SNOOZE modes, 41-µA/MHz active current, and 210-nA data retention for 4 KB of RAM. The device supports background data flash rewriting (BGO), self-programming with boot swapping, and flash shield window security - enabling secure firmware updates in field-deployed systems.
