For engineers reviewing the R5F51308ADFP#10 datasheet, R5F51308ADFP#10 pinout, R5F51308ADFP#10 application, or R5F51308ADFP#10 equivalent, key selection criteria include its 100-pin LFQFP package, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 4.8 µs wake-up time, and support for event-driven peripheral linking via ELC without CPU intervention.
Technical Context
The R5F51308ADFP#10 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip debugging circuitry. Its RX CPU core delivers 50 DMIPS at 32 MHz, supports 64-bit accumulator results from 32×32 operations, and includes fast interrupt handling with 115 vectors and 16 priority levels.
Power management integrates three low-power modes (sleep, deep sleep, software standby), a low-power timer (LPT) running off sub-clock or IWDT oscillator, and voltage detection circuits (LVD) with 14 selectable thresholds. Clock generation includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and clock accuracy measurement (CAC).
