For engineers reviewing the R5F51104ADFL#30 datasheet, R5F51104ADFL#30 pinout, R5F51104ADFL#30 application, or R5F51104ADFL#30 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-A (48-pin LFQFP, 7 × 7 mm, 0.5 mm pitch), validated peripheral channel counts per package, and direct alternative part comparisons for migration and sourcing decisions.
Technical Context
The R5F51104ADFL#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its 32-bit RX core supports 64-bit accumulator results from 32×32 multiply operations and includes dedicated hardware for division and barrel shifting.
It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 65 interrupt sources, plus independent watchdog timer (IWDT) driven by a dedicated 15 kHz on-chip oscillator - both certified for IEC 60730 functional safety compliance.
