Product details
Overview
R5F51115ADNE#2A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 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, RTC with calendar mode, and hardware event linking for low-latency peripheral coordination - deployed in industrial sensor nodes requiring deterministic real-time control and USB connectivity.
For engineers reviewing the R5F51115ADNE#2A datasheet, R5F51115ADNE#2A pinout, R5F51115ADNE#2A application, or R5F51115ADNE#2A equivalent, key selection criteria include its 48-pin HWQFN (PWQN0048KB-A) package, −40°C to +85°C temperature grade, integrated USB transceiver with BC support, 1.0 µs ADC conversion time, and ELC-triggered peripheral synchronization without CPU wake-up.
Technical Context
The R5F51115ADNE#2A 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 IEC 60730 compliance.
Peripheral coordination is managed via the Event Link Controller (ELC), enabling direct module-to-module triggering (e.g., MTU timer events initiating ADC conversions), while the Data Transfer Controller (DTC) supports chain transfers across four modes without CPU intervention - critical for deterministic motor control and sensor fusion workflows.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
Does R5F51115ADNE#2A include an integrated USB transceiver?
Yes, R5F51115ADNE#2A integrates a full-speed USB 2.0 transceiver supporting host, function, and OTG roles. It requires no external PHY - only standard USB termination (27 Ω series resistors on DP/DM) and proper VBUS monitoring circuitry. The R5F51115ADNE#2A also supports Battery Charging (BC) detection for SDP/CDP/DCP identification.
What is the maximum ADC sampling rate achievable with R5F51115ADNE#2A?
R5F51115ADNE#2A achieves a minimum conversion time of 1.0 µs per channel when ADCLK runs at 32 MHz, enabling up to 1 MSPS aggregate throughput in scan mode. Its double-trigger function allows simultaneous sampling of two channels - essential for three-phase motor current reconstruction without external sample-and-hold circuits.
Is the 8-bit D/A converter available on R5F51115ADNE#2A?
No, the dual 8-bit DAC channels (DA0/DA1) are only implemented in 64-pin RX111 variants (e.g., R5F51115AGFM). The R5F51115ADNE#2A uses the 48-pin PWQN0048KB-A package, which omits DAC bonding - confirmed in Table 1.2 (Functions by Package) and pin function tables.
How does the Event Link Controller (ELC) improve real-time performance in R5F51115ADNE#2A?
The ELC in R5F51115ADNE#2A enables hardware-level triggering between peripherals - for example, an MTU2 timer overflow can directly initiate an ADC conversion or toggle a GPIO, bypassing interrupt latency and CPU wake-up. This reduces end-to-end response time to sub-microsecond levels, critical for closed-loop motor control and synchronized sensor acquisition.
What debug interface does R5F51115ADNE#2A support?
R5F51115ADNE#2A supports the FINE interface for on-chip debugging via Renesas E1/E2 emulators. The FINED pin provides bidirectional communication for breakpoints, register inspection, and flash programming - compatible with standard Renesas development tools including CS+ and e2 studio without requiring SWD/JTAG adapters.
