For engineers reviewing the R5F52316AGFM#10 datasheet, R5F52316AGFM#10 pinout, R5F52316AGFM#10 application, or R5F52316AGFM#10 equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-C (64-pin LFQFP, 10 × 10 mm), validated peripheral capabilities including ELC-triggered timer-A/D synchronization, CTSU key count scalability, and confirmed G-version temperature range (−40 to +105°C) for extended-environment deployment.
Technical Context
The R5F52316AGFM#10 belongs to the RX231 Group and implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions. It supports 88.56 DMIPS at 54 MHz, includes on-chip MPU, and executes floating-point and DSP instructions natively - enabling deterministic real-time control in motor drives and digital power converters.
Its clock system integrates PLL, USB-dedicated PLL (48 MHz output), sub-clock oscillator (32.768 kHz), and CAC for accuracy monitoring. Power management includes three low-power modes, LPT operation during software standby, and voltage detection circuits with 14-level programmable thresholds - critical for fail-safe operation in IEC 60730-compliant appliances.
