Product details
Overview
R5F51115AGFL#1A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 Kbytes of on-chip flash, 16 Kbytes of SRAM, 8 Kbytes of data flash, a 12-bit A/D converter with 14 channels, USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial sensor nodes and low-power HMI control systems.
For engineers reviewing the R5F51115AGFL#1A datasheet, R5F51115AGFL#1A pinout, R5F51115AGFL#1A application, or R5F51115AGFL#1A equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +105°C temperature grade, USB OTG support with BC (Battery Charger) compliance, and integrated DTC/ELC for deterministic low-power peripheral coordination.
Technical Context
The R5F51115AGFL#1A 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 PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and CAC for IEC 60730 clock accuracy validation.
Peripheral integration includes Event Link Controller (ELC) enabling direct module-to-module triggering without CPU intervention, Data Transfer Controller (DTC) supporting chain transfers across four modes, and MTU2 with six 16-bit timer channels offering complementary PWM, phase counting, and A/D trigger generation - all synchronized to PCLK up to 32 MHz.
