For engineers reviewing the R5F51405BGFL#30 datasheet, R5F51405BGFL#30 pinout, R5F51405BGFL#30 application, or R5F51405BGFL#30 equivalent, key selection criteria include its 48-pin HWQFN (7 × 7 mm, 0.5 mm pitch) package, –40 to +105°C extended temperature grade, embedded AES-128/256 and RNG hardware accelerators, and support for ELC-triggered low-power peripheral operation without CPU wake-up.
Technical Context
The R5F51405BGFL#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, 32-bit multiply-accumulate and IEEE-754-compliant FPU, and on-chip 48 MHz ±1% high-speed oscillator. Its clock system supports PLL, sub-clock (32.768 kHz), and dedicated IWDT 15 kHz oscillator, with independent ICLK/PCLK/FCLK domains enabling precise timing partitioning.
It integrates event-driven peripherals via ELC - allowing MTU2 timers, SCI, and A/D conversion to operate autonomously during software standby mode (0.25 µA typ.), while the CTSU2SL capacitive touch unit supports up to 24 self-capacitance keys or 12 mutual-capacitance keys in matrix configuration per package constraints.
