Overview
R5F51101AGNE#20 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 32 Kbytes of on-chip flash, 10 Kbytes of SRAM, a 12-bit A/D converter with 10 input channels, RTC, and dual SCI interfaces - deployed in compact sensor nodes and low-power industrial control units.
For engineers reviewing the R5F51101AGNE#20 datasheet, R5F51101AGNE#20 pinout, R5F51101AGNE#20 application, or R5F51101AGNE#20 equivalent, key selection criteria include its HWQFN-48 package (7 × 7 mm, 0.5 mm pitch), −40 to +105°C extended temperature grade, 1.8–3.6 V single-supply operation, software standby current of 0.35 μA, and integrated IEC 60730 safety support functions.
Technical Context
The R5F51101AGNE#20 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit multiplication. Its clock system integrates high-speed (32 MHz ±1%), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz) oscillators with on-chip frequency accuracy measurement (CAC).
Peripheral integration includes a 4-channel MTU2 timer with phase counting and input capture, 2-channel CMT, 1-channel RIIC (I²C/SMBus), 1-channel RSPI (up to 16 Mbps), and a 12-bit A/D converter supporting double-trigger mode for motor control - all synchronized to independently configurable ICLK, PCLK, and FCLK domains.
