It operates from 2.4 V to 5.5 V and supports industrial temperature range up to +105°C (G-grade), targeting embedded control in appliance user interfaces and sensor-based industrial modules.
For engineers reviewing the R5F1216CASP#30 datasheet, R5F1216CASP#30 pinout, R5F1216CASP#30 application, or R5F1216CASP#30 equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain support for production design-in of low-power mixed-signal MCUs.
Technical Context
The R5F1216CASP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.0625 μs min @ 16 MHz to 30.5 μs @ 32.768 kHz). It integrates an on-chip high-speed oscillator (±1.0% accuracy at TA = −20 to +85°C) and dedicated low-speed oscillator for watchdog and RTC operation.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one watchdog timer, one 99-year RTC with alarm and correction, one 8/10-bit A/D converter with internal reference voltage (0.815 V), two comparators, and a 15-channel capacitive touch sensing unit supporting self- and mutual-capacitance modes.
