Renesas R5F51115AGNE#2A

Overview

R5F51115AGNE#2A 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, and 8 Kbytes of data flash. It integrates a 12-bit A/D converter (14 channels, 1.0 µs conversion), USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and operates across −40 to +105°C for industrial motor control and smart sensor applications.

For engineers reviewing the R5F51115AGNE#2A datasheet, R5F51115AGNE#2A pinout, R5F51115AGNE#2A application, or R5F51115AGNE#2A equivalent, this page delivers verified specifications, package mapping to PWQN0048KB-A (48-pin HWQFN, 7 × 7 mm, 0.5 mm pitch), functional pin roles, real-world use cases, and two validated alternative parts with technical distinctions.

Technical Context

The R5F51115AGNE#2A implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its 64-bit accumulator supports 32 × 32-bit multiply operations in one cycle, while the DTC and ELC enable interrupt-free peripheral coordination and low-power background transfers.

It features dual clock domains: ICLK (system, up to 32 MHz), PCLK (peripherals, up to 32 MHz), and FCLK (FlashIF, up to 32 MHz), with independent scaling. The MCU includes dedicated oscillators - high-speed on-chip (32 MHz ±1%), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz) - plus CAC for clock accuracy validation per IEC 60730.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51115AGNE#2A?

The R5F51115AGNE#2A operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its 32-bit RX CPU core features a five-stage pipeline, variable-length instruction encoding, and a 64-bit accumulator capable of holding full 32 × 32-bit multiplication results in a single cycle - all confirmed in the R01DS0190EJ0130 datasheet.

Does the R5F51115AGNE#2A include USB functionality, and what modes does it support?

Yes, the R5F51115AGNE#2A integrates a full-featured USB 2.0 host/function/OTG module compliant with USB 2.0 specification. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, Battery Charging (BC) detection, and On-The-Go operation - all implemented with an on-chip transceiver eliminating external PHY components.

What analog peripherals are included in the R5F51115AGNE#2A, and are they usable in low-power modes?

The R5F51115AGNE#2A includes a 12-bit A/D converter with up to 14 input channels (1.0 µs conversion time) and two 8-bit D/A converters. The A/D converter supports external trigger start and double-trigger mode for noise reduction. Both A/D and D/A remain functional in deep sleep mode when clocks are gated appropriately, as documented in Section 1.1 of R01DS0190EJ0130.

What package type and pin count does the R5F5115AGNE#2A use, and is it pin-compatible with other RX111 variants?

The R5F51115AGNE#2A uses the PWQN0048KB-A package: a 48-pin HWQFN, 7 × 7 mm body, 0.5 mm pitch with exposed thermal pad. It shares identical pinout with other RX111 48-pin variants (e.g., R5F51115ADNE#UA, R5F51116AGNE#UA), enabling drop-in replacement within the same package family - confirmed by Table 1.2 and Figure 1.5 in R01DS0190EJ0130.

How does the R5F51115AGNE#2A support functional safety standards such as IEC 60730?

The R5F51115AGNE#2A includes hardware features required for Class B compliance per IEC 60730: clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, RAM test assist functions, and voltage monitoring circuits (LVDA). These are explicitly listed in the "On-chip functions for IEC 60730 compliance" section of the datasheet.
