It targets low-power industrial sensor nodes and embedded control systems requiring deterministic real-time response and IEC 60730 compliance.
For engineers reviewing the R5F51105AGFL#30 datasheet, R5F51105AGFL#30 pinout, R5F51105AGFL#30 application, or R5F51105AGFL#30 equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +105°C extended temperature grade, software standby current of 0.35 µA, and integrated clock accuracy measurement (CAC) for functional safety.
Technical Context
The R5F51105AGFL#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its RX CPU core includes a 64-bit accumulator for 32×32-bit operations and dedicated hardware multiplier/divider.
It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 65 interrupt vectors, plus four MTU2 timer channels with input capture/output compare and phase counting, and two CMT channels for precise timing generation.
