Product details
Overview
R5F51101ADFM#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 32 KB on-chip flash, 10 KB SRAM, 14-channel 12-bit A/D converter (1.0 µs conversion), RTC with calendar mode, and dual SCI + I²C + RSPI interfaces - deployed in industrial sensor nodes requiring low-power, deterministic real-time control.
For engineers reviewing the R5F51101ADFM#30 datasheet, R5F51101ADFM#30 pinout, R5F51101ADFM#30 application, or R5F51101ADFM#30 equivalent, this page delivers verified package mapping (PLQP0064KB-A, 64-pin LFQFP), confirmed peripheral channel counts (4× MTU2 channels, 2× CMT), supply voltage range (1.8–3.6 V), software standby current (0.35 µA), and RTC-triggered wake-up capability - all validated against Renesas R01DS0202EJ0120 Rev.1.20.
Technical Context
The R5F51101ADFM#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its 64-bit accumulator supports 32×32-bit multiply-accumulate operations in one cycle, while the on-chip DTC enables interrupt-driven data transfers without CPU intervention.
It integrates dedicated clock domains: ICLK (system, up to 32 MHz), PCLK (peripherals, up to 32 MHz), and FCLK (FlashIF, up to 32 MHz), each independently configurable via clock dividers. The high-speed on-chip oscillator delivers ±1% accuracy across −40°C to +85°C, and the CAC circuit validates clock frequency for IEC 60730 compliance.
