Product details
Overview
R5F51405ADFN#30 from Renesas is a 32-bit RXv2 core MCU operating at up to 48 MHz, featuring 128 KB flash, 32 KB SRAM, 12-bit A/D converter with 18 channels, two 8-bit D/A channels, and integrated capacitive touch sensing supporting up to 36 keys. It delivers 204 CoreMark performance and includes IEEE-754-compliant FPU, hardware divider, and IEC60730 safety support for industrial control applications.
For engineers reviewing the R5F51405ADFN#30 datasheet, R5F51405ADFN#30 pinout, R5F51405ADFN#30 application, or R5F51405ADFN#30 equivalent, key selection criteria include its 80-pin LFQFP (PLQP0080KB-B) package, CAN module compliance with ISO11898-1 at 1 Mbps, low-power software standby mode consuming 0.25 µA (typ.), and real-time clock with calendar count mode - all critical for battery-powered HMI and motor control designs.
Technical Context
The R5F51405ADFN#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. Its on-chip peripherals include a 16-bit MTU2a timer unit with six channels supporting complementary PWM and phase counting, plus an ELC that enables event-triggered module operation without CPU intervention during sleep.
It integrates dual-clock domain operation: ICLK up to 48 MHz for CPU/system, PCLKB up to 32 MHz for peripherals, and FCLK at 48 MHz for FlashIF. The S12ADE A/D converter operates with ADCLK synchronized to PCLKD up to 48 MHz, achieving 0.67 µs minimum conversion time per channel - confirmed for this 128 KB ROM variant in the 80-pin package.
