For engineers reviewing the R5F51306ADFN#30 datasheet, R5F51306ADFN#30 pinout, R5F51306ADFN#30 application, or R5F51306ADFN#30 equivalent, this page delivers verified specifications, package mapping to PLQP0080KB-B (80-pin LFQFP, 12×12 mm, 0.5 mm pitch), validated pin functions, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The R5F51306ADFN#30 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip debugging. It integrates an ELC for event-driven peripheral coordination without CPU intervention and a DTC supporting normal, repeat, and block transfer modes triggered by 47 event sources.
Its clock system includes high-speed (32 MHz ±1%) and low-speed (15 kHz) on-chip oscillators, PLL, sub-clock (32.768 kHz), and CAC for frequency accuracy measurement. Power management supports three low-power modes, including software standby with 0.37 µA supply current and 4.8 µs wake-up time.
