Product details
Overview
R5F51114ADFK#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 96 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 14-channel 12-bit ADC, dual 8-bit DACs, USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial HMI and sensor gateway applications requiring deterministic real-time control and low-power operation.
For engineers reviewing the R5F51114ADFK#3A datasheet, R5F51114ADFK#3A pinout, R5F51114ADFK#3A application, or R5F51114ADFK#3A equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40°C to +85°C temperature grade, USB OTG capability with BC support, 4.8 μs wake-up from software standby mode, and integrated IEC 60730 safety functions for Class B compliance.
Technical Context
The R5F51114ADFK#3A implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for frequency accuracy monitoring.
Peripheral integration includes Event Link Controller (ELC) for interrupt-free inter-module triggering, Data Transfer Controller (DTC) supporting chain transfers across 82 interrupt sources, and MTU2 timer unit with six 16-bit channels for complementary PWM and phase counting - enabling motor control and precision timing without CPU intervention.
Key Specifications
