Product details
Overview
R5F5111JAGNF#2A 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, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC, and operates across −40°C to +105°C in a 40-pin HWQFN package (PWQN0040KC-A, 6 × 6 mm, 0.5 mm pitch). It targets compact industrial control and USB-enabled sensor nodes.
For engineers reviewing the R5F5111JAGNF#2A datasheet, R5F5111JAGNF#2A pinout, R5F5111JAGNF#2A application, or R5F5111JAGNF#2A equivalent, key selection criteria include its 40-pin thermal-performance-optimized footprint, USB OTG support with BC (Battery Charger) compliance, 1.0 µs A/D conversion time, software standby current of 0.44 µA, and integrated CAC for IEC 60730 Class B certification.
Technical Context
The R5F5111JAGNF#2A implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit multiply operations. Its clock system includes a 32 MHz ±1% high-speed on-chip oscillator, PLL (4–8 MHz input), sub-clock (32.768 kHz), and IWDT-dedicated 15 kHz oscillator - all configurable via independent ICLK/PCLK/FCLK domains.
It supports event-driven operation via the Event Link Controller (ELC), allowing peripheral modules (e.g., MTU2 timers, A/D) to trigger actions without CPU intervention - critical for low-latency motor control and real-time sensor acquisition. The DTC enables chain-transfer DMA across four modes, while the E2 DataFlash provides 1,000,000 erase/write cycles with background operation (BGO) for firmware updates during runtime.
