Overview
R5F51114AGNE#2A 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 A/D converter (1.0 µs conversion), two 8-bit D/A outputs, USB 2.0 full-speed host/function/OTG, and RTC with calendar mode - deployed in industrial sensor nodes requiring low-power, mixed-signal control and USB connectivity.
For engineers reviewing the R5F51114AGNE#2A datasheet, R5F51114AGNE#2A pinout, R5F51114AGNE#2A application, or R5F51114AGNE#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 validated alternative parts for design continuity and supply resilience.
Technical Context
The R5F51114AGNE#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. It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 82 interrupt sources.
Its clock system includes high-speed (32 MHz ±1%) and low-speed (15 kHz) on-chip oscillators, PLL, sub-clock (32.768 kHz), and Clock Accuracy Measurement (CAC) circuit - enabling IEC 60730-compliant safety monitoring. The Event Link Controller (ELC) allows direct module-to-module triggering without CPU intervention, including wake-up from software standby mode via RTC alarm.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51114ADNE#UA | Same package (PWQN0048KB-A), identical memory/peripheral set, but rated for −40°C to +85°C (D-grade) instead of +105°C (G-grade). | Suitable for commercial/indoor environments without extended thermal stress; lacks high-temp qualification for under-hood or factory-floor deployments. | Select R5F51114ADNE#UA only when ambient operating temperature remains ≤85°C and cost sensitivity outweighs thermal margin requirements. |
| R5F51115AGNE#UA | Same package and G-grade temp range, but upgraded to 128 KB flash, 16 KB SRAM, and same 8 KB data flash - no peripheral reduction. | Enables larger protocol stacks (e.g., USB CDC + BLE coexistence), more complex control algorithms, or dual-application firmware partitioning. | Choose R5F51115AGNE#UA when future firmware growth, safety redundancy, or enhanced logging capacity is anticipated - pin-compatible and drop-in upgrade path. |
