Product details
Overview
R5F5110JADNE#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 10 channels, RTC, and dual SCI interfaces - deployed in industrial sensor nodes requiring low-power, deterministic real-time control and secure firmware updates.
For engineers reviewing the R5F5110JADNE#20 datasheet, R5F5110JADNE#20 pinout, R5F5110JADNE#20 application, or R5F5110JADNE#20 equivalent, key selection criteria include its HWQFN-48 package (7 × 7 mm, 0.5 mm pitch), −40 to +85°C temperature grade, 1.8–3.6 V supply range, software standby mode (0.35 μA), and IEC 60730-compliant safety features for Class B appliance control.
Technical Context
The R5F5110JADNE#20 implements the RXv1 CPU core with CISC Harvard architecture, five-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a dedicated 32 MHz ±1% on-chip oscillator, clock frequency accuracy measurement circuit (CAC), and independent watchdog timer (IWDT) driven by a 15 kHz on-chip oscillator - all supporting functional safety compliance per IEC 60730.
Its peripheral set includes two SCI modules (SCI1 and SCI5) supporting asynchronous, clock-synchronous, simple I²C, and simple SPI modes; one I²C bus interface (RIIC); one RSPI channel; MTU2 timer unit with four 16-bit channels; and a 12-bit A/D converter with double-trigger capability for motor current sampling - all accessible via multi-function pin controller (MPC) routing.
