For engineers reviewing the R5F51403AGFJ#10 datasheet, R5F51403AGFJ#10 pinout, R5F51403AGFJ#10 application, or R5F51403AGFJ#10 equivalent, this page delivers verified specifications, package mapping to PLQP0032GB-A (32-pin LQFP, 7×7 mm, 0.8 mm pitch), functional pin roles, real-world use cases, and validated alternative parts - all extracted from Renesas R01DS0379EJ0120 Rev.1.20.
Technical Context
The R5F51403AGFJ#10 implements the RXv2 CPU core with IEEE-754-compliant 32-bit FPU, 204 CoreMark @48 MHz, and on-chip divider (2-cycle latency). Its clock system integrates HOCO (48 MHz ±1%), sub-clock (32.768 kHz), PLL, and IWDT-dedicated 15 kHz oscillator with CAC for accuracy monitoring.
Peripheral integration includes ELC for event-driven module activation without CPU wake-up, DTC for five transfer modes, MPC for flexible pin function assignment, and CTSU2SL supporting self-capacitance (24-key) and mutual-capacitance (8×8 matrix) touch sensing - all confirmed for the 32-pin variant per Table 1.2.
