Product details
Overview
R5F5110JADNF#20 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 16 KB on-chip flash, 8 KB SRAM, 12-bit A/D converter with 7 input channels, RTC, and dual SCI interfaces - deployed in battery-powered sensor nodes and industrial control edge devices.
For engineers reviewing the R5F5110JADNF#20 datasheet, R5F5110JADNF#20 pinout, R5F5110JADNF#20 application, or R5F5110JADNF#20 equivalent, this page delivers verified package mapping (PWQN0040KC-A), confirmed low-power modes (software standby: 0.35 µA), real-time clock calendar mode, and validated alternative parts for migration or second-sourcing.
Technical Context
The R5F5110JADNF#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 on-chip debugging uses FINE interface, and clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators with CAC accuracy measurement.
It supports three low-power modes - sleep, deep sleep, and software standby (4.8 µs wake-up) - with supply voltage range 1.8–3.6 V. Peripheral integration includes MTU2 (4-channel 16-bit timer), CMT (2-channel), RIIC (I²C, 400 kbps), RSPI (16 Mbps), and 12-bit S12AD with double-trigger capability for motor sensing.
