Overview
R5F51405BDNE#30 from Renesas is a 32-bit RXv2 core MCU operating at up to 48 MHz, featuring 128 KB flash, 32 KB SRAM, 8 KB data flash, single-precision FPU, and integrated CAN, 12-bit A/D (11 channels), dual 8-bit D/A, capacitive touch sensing (24 keys), and AES/RNG encryption. It targets low-power industrial control and sensor-edge applications requiring IEC60730 compliance.
For engineers reviewing the R5F51405BDNE#30 datasheet, R5F51405BDNE#30 pinout, R5F51405BDNE#30 application, or R5F51405BDNE#30 equivalent, key selection criteria include its 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch), –40 to +85°C temperature grade, 1.8–5.5 V supply, 0.25 µA software standby current, and support for event-driven low-power operation via ELC and LPT.
Technical Context
The R5F51405BDNE#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip debugging. Its clock system integrates HOCO (48 MHz ±1%), sub-clock oscillator (32.768 kHz), PLL, and CAC for accuracy monitoring - all configurable per peripheral domain (ICLK/PCLKB/PCLKD/FCLK).
Peripheral integration includes RSCAN (CAN 2.0B, 1 Mbps), S12ADE (11-channel 12-bit A/D, 0.67 µs conversion), MTU2a (6-channel 16-bit timer with PWM/phase counting), and CTSU2SL (24-key self-capacitance touch). Encryption is enabled via AESA (128/256-bit) and RNGA, while IEC60730 support covers RAM test, ADC self-diagnostic, and clock accuracy validation.
